INTRODUCTION [R-072015]

This chapter is designed to be a guide for patentexaminers in searching and examining applicationsfiled under the Patent Cooperation Treaty (PCT)Applicants desiring additional information for filinginternational applications should obtain a copy ofthe PCT Applicantrsquos Guide from the WorldIntellectual Property Organization (WIPO) inGeneva Switzerland

The Articles and Regulations under the PCT arereproduced in Appendix T of this Manual and theAdministrative Instructions are reproduced inAppendix AI of this Manual The text of the PCTApplicantrsquos Guide the monthly PCT Newsletter the weekly PCT Gazette downloadable PCT formsand additional information about the processing ofinternational applications are available from WIPOrsquoswebsite (wwwwipoint)

PCT applications are processed by the InternationalApplication Processing Division within the USPatent and Trademark Office

1801 Basic Patent Cooperation Treaty (PCT)Principles [R-072015]

I MAJOR CONCEPTS OF THE PCT

The Patent Cooperation Treaty (PCT) enables theUS applicant to file one application ldquoaninternational applicationrdquo in a standardized formatin English in the US Receiving Office (the USPatent and Trademark Office) and have thatapplication acknowledged as a regular national orregional filing in as many Contracting States to thePCT as the applicant ldquodesignatesrdquo that is namesas countries or regions in which patent protection isdesired The filing of an international applicationwill automatically constitute the designation of allcontracting countries to the PCT on that filing date

Rev 072015 October 20151800-3

sect 1801PATENT COOPERATION TREATY

In the same manner the PCT enables foreignapplicants to file a PCT international applicationdesignating the United States of America in theirhome language in their home patent office and havethe application acknowledged as a regular USnational filing The PCT also provides for theestablishment of an international search report andwritten opinion at 16 months from the priority dateand publication of the international application after18 months from the priority date Upon payment ofnational fees and the furnishing of any requiredtranslation usually 30 months after the filing of anypriority application for the invention or theinternational filing date if no priority is claimed theapplication will be subjected to national proceduresfor granting of patents in each of the designatedcountries For any countries remaining whosenational laws are not compatible with the 30 monthperiod set forth in PCT Article 22(1) the filing of ademand for an international preliminary examinationelecting such countries within 19 months from thepriority date will result in an extension of the periodfor entering the national stage to 30 months fromthe priority date An up-to-date list of such countriesmay be found on WIPOrsquos website (wwwwipointpctentextsreservationsres_incomphtml) Seealso subsection V below A brief description of thebasic flow under the PCT is provided in MPEP sect1842

The PCT offers an alternative route to filing patentapplications directly in the patent offices of thosecountries which are Contracting States of the PCTIt does not preclude taking advantage of the priorityrights and other advantages provided under the ParisConvention and the WTO administered Agreementon Trade-Related Aspects of Intellectual Property(TRIPS Agreement) The PCT provides an additionaland optional foreign filing route to patent applicants

The filing search and publication procedures areprovided for in Chapter I of the PCT Additionalprocedures for a preliminary examination of PCTinternational applications are provided for in optionalPCT Chapter II

In most instances a national US application is filedfirst An international application for the samesubject matter will then be filed subsequently withinthe priority year provided by the Paris Convention

and the priority benefit of the US nationalapplication filing date will be claimed

II RECEIVING OFFICE (RO)

The international application (IA) must be filed inthe prescribed receiving Office (RO)(PCT Article10) The United States Patent and Trademark Officewill act as a receiving Office for United Statesresidents and nationals (35 USC 361(a)) UnderPCT Rule 191(a)(iii) the International Bureau ofthe World Intellectual Property Organization willalso act as a Receiving Office for US residents andnationals The receiving Office functions as the filingand formalities review organization for internationalapplications International applications must containupon filing the designation of at least oneContracting State in which patent protection isdesired and must meet certain standards forcompleteness and formality (PCT Articles 11(1) and14(1))

Where a priority claim is made the date of theearliest-filed application whose priority is claimedis used as the date for determining the timing ofinternational processing including the varioustransmittals the payment of certain international andnational fees and publication of the applicationWhere no priority claim is made the internationalfiling date will be considered to be the ldquopriority daterdquofor timing purposes (PCT Article 2(xi))

The international application is subject to thepayment of certain fees within 1 month from thedate of receipt See PCT Rules 141(c) 153 and161(f) The receiving Office will grant aninternational filing date to the application collectfees handle informalities by direct communicationwith the applicant and monitor all corrections (35USC 361(d)) By 13 months from the priority datethe receiving Office should prepare and transmit acopy of the international application called thesearch copy (SC) to the International SearchingAuthority (ISA) and forward the original called therecord copy (RC) to the International Bureau (IB)(PCT Rules 221 and 23) A second copy of theinternational application the home copy (HC)remains in the receiving Office (PCT Article 12(1))Once the receiving Office has transmitted copies of

1800-4Rev 072015 October 2015

MANUAL OF PATENT EXAMINING PROCEDUREsect 1801

the application the International Searching Authoritybecomes the focus of international processing

III INTERNATIONAL SEARCHING AUTHORITY(ISA)

The basic functions of the International SearchingAuthority (ISA) are to conduct a prior art search ofinventions claimed in international applications (itdoes this by searching in at least the minimumdocumentation defined by the Treaty (PCT Articles15 and 16 and PCT Rule 34)) and to issue a writtenopinion (PCT Rule 43 bis ) which will normally beconsidered to be the first written opinion of theInternational Preliminary Examining Authoritywhere international preliminary examination isdemanded See PCT Rule 661 bis

For most applications filed with the United StatesReceiving Office the applicant may choose (in theRequest form) the US Patent and Trademark Officethe European Patent Office the Korean IntellectualProperty Office the Australian Patent Office (IPAustralia) the Federal Service for IntellectualProperty (Rospatent) (Russian Federation) the IsraelPatent Office (ILPO) or the Japan Patent Office(JPO) to act as the International Searching AuthorityHowever IP Australia ILPO and JPO may not becompetent to act as an International SearchingAuthority for certain applications filed by nationalsor residents of the United States See MPEP sectsect184001 - 184006 for a discussion of competencyof ISAEP ISAKR ISAAU ISARU ISAIL andISAJP The International Searching Authority isalso responsible for checking the content of the titleand abstract (PCT Rules 372 and 382)

An international search report (ISR) and writtenopinion will normally be issued by the InternationalSearching Authority within 3 months from thereceipt of the search copy (usually about 16 monthsafter the priority date) (PCT Rule 42) Copies of theinternational search report and prior art cited will bemade available to the applicant by the ISA (PCTRules 43 and 441) The international search reportwill contain a listing of documents found to berelevant and will identify the claims in theapplication to which they are pertinent The writtenopinion indicates whether each claim appears tosatisfy the PCT Article 33 criteria of ldquonoveltyrdquo

ldquoinventive steprdquo and ldquoindustrial applicabilityrdquo Thewritten opinion may also indicate defects in the formor content of the international application under thePCT articles and regulations as well as anyobservations the ISA wishes to make on the clarityof the claims the description and the drawings oron the question of whether the claims are fullysupported by the description

Once the international search report and writtenopinion are established the ISA transmits one copyof each to the applicant and the International Bureauand international processing continues before theInternational Bureau If a Demand for Chapter IIexamination is not timely filed the InternationalBureau communicates a copy of the written opinionestablished by the ISA (retitled InternationalPreliminary Report on Patentability (Chapter I ofthe PCT)) to each designated Office after theexpiration of 30 months from the priority date

IV INTERNATIONAL BUREAU (IB)

The basic functions of the International Bureau (IB)are to maintain the master file of all internationalapplications and to act as the publisher and centralcoordinating body under the Treaty The WorldIntellectual Property Organization (WIPO) inGeneva Switzerland performs the duties of theInternational Bureau

If the applicant has not filed a certified copy of thepriority document in the receiving Office with theinternational application requested upon filing thatthe receiving Office prepare and transmit to theInternational Bureau a copy of the prior US nationalapplication the priority of which is claimed orrequested the International Bureau to obtain a copyof the earlier application from a digital library theapplicant must submit such a document directly tothe International Bureau or the receiving Office notlater than 16 months after the priority date (PCTRule 17) The request (Form PCTRO101) containsa box which can be checked requesting the receivingOffice to prepare and transmit a copy of a priorapplication This is only possible of course if thereceiving Office is a part of the same national Officewhere the priority application was filed The request(Form PCTRO101) also contains a box which canbe checked requesting the International Bureau to

Rev 072015 October 20151800-5


obtain a copy of the earlier application from a digitallibrary This is only possible if the application isregistered in a digital library made available to theInternational Bureau within the prescribed time limitas set forth in PCT Rule 171(b- bis) and the accesscode is furnished to the International Bureau

The applicant has normally 2 months from the dateof transmittal of the international search report toamend the claims by filing an amendment and mayfile a brief statement explaining the amendmentdirectly with the International Bureau (PCT Article19 and PCT Rule 46) The International Bureau willthen normally publish the international applicationalong with the search report and any amended claimsat the expiration of 18 months from the priority date(PCT Article 21) For applications filed before July1 2014 former PCT Rule 44 ter provided that thewritten opinion of the ISA would not be madepublicly available until the expiration of 30 monthsfrom the priority date For applications filed on orafter July 1 2014 the written opinion of the ISAand any informal comments submitted by theapplicant are made available to the public in theiroriginal language as of the publication date Theinternational publication includes a front pagecontaining bibliographical data the abstract and afigure of the drawing (PCT Rule 48) The publicationalso contains the search report and any amendmentsto the claims submitted by the applicant If theapplication is published in a language other thanEnglish the search report and abstract are alsopublished in English The International Bureaupublishes a PCT Gazette in the French and Englishlanguages which contains information similar to thaton the front pages of published internationalapplications as well as various indexes andannouncements (PCT Rule 86) The InternationalBureau also communicates copies of the publicationof the international application to all designatedOffices that have requested to receive the publication(PCT Article 20 PCT Rule 47 and PCT Rule93 bis1)

V DESIGNATED OFFICE (DO) and ELECTEDOFFICE (EO)

The designated Office is the national Office (forexample the USPTO) acting for the state or regiondesignated under Chapter I Similarly the elected

Office is the national Office acting for the state orregion elected under Chapter II

PCT Article 22(1) was amended effective April 12002 to specify that a copy of the internationalapplication a translation thereof (as prescribed) andthe national fee are due to the designated Office notlater than at the expiration of 30 months from thepriority date Accordingly the time period for filingthe copy of the international application thetranslation and the fee under PCT Article 22 is thesame as the 30 month time period set forth in PCTArticle 39 The USPTO has adopted the 30 monthtime limit set forth in PCT Article 22(1) MostContracting States have changed their national lawsfor consistency with PCT Article 22(1) as amendedAn up-to-date listing of Contracting States that haveadopted Article 22(1) as amended is maintained atWIPOrsquos website at wwwwipointpctentextstime_limitshtml At the time ofpublication of this Chapter only three countries havenot adopted Article 22(1) as amended Luxembourg(LU) United Republic of Tanzania (TZ) and Uganda(UG) It is noted that Luxembourg is included in theregional designation ldquoEPOrdquo and that the UnitedRepublic of Tanzania and Uganda are included inthe regional designation ldquoARIPOrdquo For those fewremaining Contracting States that have not adoptedArticle 22(1) as amended if no ldquoDemandrdquo forinternational preliminary examination has been filedwithin 19 months of the priority date the applicantmay be required to complete the requirements forentering the national stage within 20 months fromthe priority date of the international application inthe national offices of those states When enteringthe national stage following Chapter I the applicanthas the right to amend the application within thetime limit set forth in PCT Rule 521 After this timelimit has expired (PCT Article 28 and PCT Rule 52)each designated Office will make its owndetermination as to the patentability of theapplication based upon its own specific national orregional laws (PCT Article 27(5))

If the applicant desires to obtain the benefit ofdelaying the entry into the national stage until 30months from the priority date in one or morecountries where the 30 month time limit set forth inPCT Article 22(1) as amended does not apply aDemand for international preliminary examination

1800-6Rev 072015 October 2015


must be filed with an appropriate InternationalPreliminary Examining Authority (IPEA) within 19months of the priority date

Those states in which the Chapter II procedure isdesired must be ldquoelectedrdquo in the Demand

PCT Rule 54 bis1 requires the Demand to be madeprior to the expiration of whichever of the followingperiods expires later

(A) three months from the date of transmittal tothe applicant of the international search report or ofthe declaration referred to in PCT Article 17(2)(a)and of the written opinion under PCT Rule 43 bis1or

(B) 22 months from the priority date

However applicant may desire to file the Demandby 19 months from the priority date to extend thenational stage entry deadline in Luxembourg theUnited Republic of Tanzania and Uganda

The original Demand is forwarded to theInternational Bureau by the IPEA The InternationalBureau then notifies the various elected Offices thatthe applicant has entered Chapter II and sends a copyof any amendments filed under PCT Article 19 andany statement explaining the amendments and thebasis for the amendments to the IPEA See PCT Rule62 The International Bureau also sends the IPEA acopy of the written opinion established by theInternational Searching Authority (ISA) unless theISA is also acting as the IPEA See PCT Rule 621(i)

VI INTERNATIONAL PRELIMINARYEXAMINING AUTHORITY (IPEA)

The International Preliminary Examining Authority(IPEA) normally starts the examination process whenit is in possession of

(A) the Demand

(B) the amount due

(D) either the international search report or anotice of the declaration by the InternationalSearching Authority (ISA) that no internationalsearch report will be established and

(E) the written opinion established under PCTRule 43 bis1

However the IPEA shall not start the internationalpreliminary examination before the expiration of thelater of three months from the transmittal of theinternational search report (or declaration that nointernational search report will be established) andwritten opinion or the expiration of 22 months fromthe priority date unless the applicant expresslyrequests an earlier start with the exception of thesituations provided for in PCT Rule 691(b) - (e)

The written opinion of the ISA is usually consideredthe first written opinion of the IPEA unless the IPEAhas notified the International Bureau that writtenopinions established by specified InternationalSearching Authorities shall not be considered awritten opinion for this purpose See PCT Rule661 bis Also the IPEA may at its discretion issuefurther written opinions provided sufficient time isavailable See PCT Rule 664

The IPEA establishes the international preliminaryexamination report (entitled ldquointernationalpreliminary report on patentabilityrdquo) which presentsthe examinerrsquos final position as to whether eachclaim is ldquonovelrdquo involves ldquoinventive steprdquo and isldquoindustrially applicablerdquo by 28 months from thepriority date A copy of the international preliminaryexamination report is sent to the applicant and to theInternational Bureau The International Bureau thencommunicates a copy of the international preliminaryexamination report to each elected Office

The applicant must complete the requirements forentering the national stage by the expiration of 30months from the priority date to avoid any questionof withdrawal of the application as to that electedOffice however some elected Offices provide alonger period to complete the requirements

1803 Reservations Under the PCT Taken byand Notifications of Incompatibility Madeby the United States of America [R-072015]

The United States of America had originally declaredthat it was not bound by Chapter II (PCT Article64(1)) but withdrew that reservation on July 1 1987

It has also declared that as far as the United Statesof America is concerned international publicationis not required (PCT Article 64 (3)) Accordinglyunder PCT Article 64(3)(b) if the United States isthe only PCT Contracting State designated in aninternational application the international applicationwill not be published by the International Bureau(IB) at 18 months Even though the United StatesPatent and Trademark Office has pre-grantpublication under 35 USC 122(b) the United Stateshas not removed its reservation under PCT Article64(3) because not all United States patentapplications are published See 35 USC 122(b)(2)The application will however be published under35 USC 122(b) if it enters the national stage in theUnited States It will be published again if it isallowed to issue as a United States patent Thisreservation is still in effect

The US Receiving Office continues to acceptapplications only in English See 35 USC 361(c)PCT Rules 201(c) 263 ter(a) and 263 ter(c) permitan international filing date to be accorded eventhough portions of an international application arein a language not acceptable to the Receiving OfficePCT Rules 201(c) 263 ter(a) and 263 ter(c) arenot compatible with the national law applied by the

United States Patent and Trademark Office (USPTO)as receiving Office Thus the USPTO has made anotification of incompatibility with respect to theserules pursuant to PCT Rules 201(d) 263 ter(b) and263 ter(d) As a result PCT Rules 201(c)263 ter(a) and 263 ter(c) shall not apply to theUSPTO as receiving Office for as long as theaforementioned incompatibility exists

PCT Rules 495(c- bis) and 495(k) continue not tobe compatible with the national law applied by theUSPTO as a designated Office See 35 USC371(c)(2) Also PCT Rules 49 ter1(a)-(d) and49 ter2(a)-(g) are not compatible with the nationallaw applied by the USPTO as a designated OfficeSee 35 USC 119(a) Thus the USPTO has madea notification of incompatibility with respect to theseRules pursuant to PCT Rules 495(l) 49 ter1(g) and49 ter2(h) As a result PCT Rules 495(c- bis)495(k) 49 ter1(a)-(d) and 49 ter2(a)-(g) shall notapply to the USPTO as designated Office for as longas the aforementioned incompatibility exists Seethe International Bureaursquos notice published on theWIPO website at wwwwipointpctentextsreservationsres_incomphtml

REFERENCES TO DEPOSITED BIOLOGICALMATERIAL IN THE CASE OFMICROBIOLOGICAL INVENTIONS

The PCT does not require the inclusion of a referenceto a biological material andor to its deposit with adepositary institution in an international application

it merely prescribes the contents of any ldquoreferenceto deposited biological materialrdquo (defined asldquoparticulars given with respect to the deposit ofbiological material or to the biological material sodepositedrdquo) which is included in an internationalapplication and when such a reference must befurnished It follows that the applicant may see aneed to make such a reference only when it isrequired for the purpose of disclosing the inventionclaimed in the international application in a mannersufficient for the invention to be carried out by aperson skilled in the art that is when the law of atleast one of the designated States provides for themaking for this purpose of a reference to adeposited biological material if the inventioninvolves the use of a biological material that is notavailable to the public Any reference to a depositedbiological material furnished separately from thedescription will be included in the publication of theinternational application

A reference to a deposited biological material madein accordance with the requirements of the PCT mustbe regarded by each of the designated Offices assatisfying the requirements of the national lawapplicable in that Office with regard to the contentsof such references and the time for furnishing them

A reference may be made for the purposes of alldesignated States or for one or only some of thedesignated States A reference is considered to bemade for the purpose of all designated States unlessit is expressly made for certain designated Statesonly References to different deposits may be madefor the purposes of different designated States

There are two kinds of indication which may haveto be given with regard to the deposit of thebiological material namely

(A) indications specified in the PCT Regulationsthemselves and

(B) additional indications by the national (orregional) Office of (or acting for) a State designatedin the international application and which have beenpublished in the PCT Gazette these additionalindications may relate not only to the deposit of thebiological material but also to the biological materialitself

1800-26Rev 072015 October 2015


The indications in the first category are

(1) the name and the address of the depositaryinstitution with which the deposit was made

(2) the date of the deposit with that institution and

(3) the accession number given to the deposit by thatinstitution

US requirements include the name and address ofthe depository institution at the time of filing thedate of the deposit or a statement that the depositwas made on or before the priority date of theinternational application and to the extent possiblea taxonomic description of the biological materialSee Annex L of the PCT Applicantrsquos Guide

The national laws of some of the national (orregional) Offices require that besides indicationsconcerning the deposit of a biological material anindication be given concerning the biologicalmaterial itself such as for example a shortdescription of its characteristics at least to the extentthat this information is available to the applicantThese requirements must be met in the case ofinternational applications for which any such Officeis a designated Office provided that the requirementshave been published in the PCT Gazette Annex Lof the PCT Applicantrsquos Guide indicates for each ofthe national (or regional) Offices the requirements(if any) of this kind which have been published

If any indication is not included in a reference to adeposited biological material contained in theinternational application as filed it may be furnishedto the International Bureau within 16 months afterthe priority date unless the International Bureau hasbeen notified (and at least 2 months prior to thefiling of the international application it haspublished in the PCT Gazette) that the national lawrequires the indication to be furnished earlierHowever if the applicant makes a request for earlypublication all indications should be furnished bythe time the request is made since any designatedOffice may regard any indication not furnished whenthe request is made as not having been furnished intime

No check is made in the international phase todetermine whether a reference has been furnishedwithin the prescribed time limit However theInternational Bureau notifies the designated Officesof the date(s) on which indications not included inthe international application as filed were furnishedto it Those dates are also mentioned in thepublication of the international application Failureto include a reference to a deposited biologicalmaterial (or any indication required in such areference) in the international application as filedor failure to furnish it (or the indication) within theprescribed time limit has no consequence if thenational law does not require the reference (orindication) to be furnished in a national applicationWhere there is a consequence it is the same as thatwhich applies under the national law

To the extent that indications relating to the depositof a biological material are not given in thedescription because they are furnished later theymay be given in the ldquooptional sheetrdquo provided forthat purpose If the sheet is submitted when theinternational application is filed a reference to itshould be made in the check list contained on thelast sheet of the Request form Should certain Statesbe designated eg Israel Japan Korea Mexico orTurkey such a sheet must if used be included asone of the sheets of the description at the time offiling otherwise the indications given in it will notbe taken into account by the respective patent officesof those designated States in the national phaseRequirements of the various Offices are set forth inAnnex L of the PCT Applicantrsquos Guide availableonline at wwwwipointpctenappguide If thesheet is furnished to the International Bureau laterit must be enclosed with a letter

Each national (or regional) Office whose nationallaw provides for deposits of biological material forthe purposes of patent procedure notifies theInternational Bureau of the depositary institutionswith which the national law permits such depositsto be made Information on the institutions notifiedby each of those Offices is published by theInternational Bureau in the PCT Gazette

A reference to a deposit cannot be disregarded by adesignated Office for reasons pertaining to theinstitution with which the biological material was

Rev 072015 October 20151800-27


deposited if the deposit referred to is one made witha depositary institution notified by that Office Thusby consulting the PCT Gazette or Annex L of thePCT Applicantrsquos Guide the applicant can be surethat he has deposited the biological material with aninstitution which will be accepted by the designatedOffice

International Searching Authorities and InternationalPreliminary Examining Authorities are not expectedto request access to deposited biological materialHowever in order to retain the possibility of accessto a deposited biological material referred to in aninternational application which is being searched orexamined by such an Authority the PCT providesthat the Authorities may if they fulfill certainconditions ask for samples Thus an Authority mayonly ask for samples if it has notified theInternational Bureau (in a general notification) thatit may require samples and the International Bureauhas published the notification in the PCT GazetteThe only Authority which has made such anotification (and thus the only Authority which mayrequest samples) is the Japan Patent Office If asample is asked for the request is directed to theapplicant who then becomes responsible for makingthe necessary arrangements for the sample to beprovided

The furnishing of samples of a deposit of a biologicalmaterial to third persons is governed by the nationallaws applicable in the designated Offices PCT Rule13 bis6(b) however provides for the delaying ofany furnishing of samples under the national lawapplicable in each of the designated (or elected)Offices until the start of the national phase subjectto the ending of this ldquodelaying effectrdquo brought aboutby the occurrence of either of the following twoevents

(A) the applicant has after internationalpublication of the international application takenthe steps necessary to enter the national phase beforethe designated Office

(B) international publication of the internationalapplication has been effected and that publicationhas the same effects under the national lawapplicable in the designated Office as thecompulsory national publication of an unexaminednational application (in other words the international

application has qualified for the grant of ldquoprovisionalprotectionrdquo)

Nucleotide andor Amino Acid Sequence Listings

13 ter1 Procedure Before the International SearchingAuthority

(a) Where the international application contains disclosureof one or more nucleotide andor amino acid sequences theInternational Searching Authority may invite the applicant tofurnish to it for the purposes of the international search asequence listing in electronic form complying with the standardprovided for in the Administrative Instructions unless suchlisting in electronic form is already available to it in a form andmanner acceptable to it and to pay to it where applicable thelate furnishing fee referred to paragraph (c) within a time limitfixed in the invitation

(b) Where at least part of the international application isfiled on paper and the International Searching Authority findsthat the description does not comply with Rule 52(a) it mayinvite the applicant to furnish for the purposes of theinternational search a sequence listing in paper form complyingwith the standard provided for in the Administrative Instructionsunless such listing in paper form is already available to it in aform and manner acceptable to it whether or not the furnishingof a sequence listing in electronic form is invited underparagraph (a) and to pay where applicable the late furnishingfee referred to in paragraph (c) within a time limit fixed in theinvitation

(c) The furnishing of a sequence listing in response to aninvitation under paragraph (a) or (b) may be subjected by theInternational Searching Authority to the payment to it for itsown benefit of a late furnishing fee whose amount shall bedetermined by the International Searching Authority but shallnot exceed 25 of the international filing fee referred to in item1 of the Schedule of Fees not taking into account any fee foreach sheet of the international application in excess of 30 sheets

1800-28Rev 072015 October 2015


provided that a late furnishing fee may be required under eitherparagraph (a) or (b) but not both

(d) If the applicant does not within the time limit fixed inthe invitation under paragraph (a) or (b) furnish the requiredsequence listing and pay any required late furnishing fee theInternational Searching Authority shall only be required tosearch the international application to the extent that ameaningful search can be carried out without the sequencelisting

(e) Any sequence listing not contained in the internationalapplication as filed whether furnished in response to aninvitation under paragraph (a) or (b) or otherwise shall not formpart of the international application but this paragraph shall notprevent the applicant from amending the description in relationto a sequence listing pursuant to Article 34(2)(b)

(f) Where the International Searching Authority finds thatthe description does not comply with Rule 52(b) it shall invitethe applicant to submit the required correction Rule 264 shallapply mutatis mutandis to any correction offered by theapplicant The International Searching Authority shall transmitthe correction to the receiving Office and to the InternationalBureau

Sequence Listings

Any sequence listing whether on paper or in electronic formwhether forming part of the international application or notforming part of the international application shall comply withAnnex C

I REQUIREMENTS FOR SEQUENCE LISTINGS

Where an international application discloses one ormore nucleotide andor amino acid sequences thedescription must contain a sequence listingcomplying with the standard specified in theAdministrative Instructions The standard is set forthin detail in Annex C - Standard for the Presentationof Nucleotide and Amino Acid Sequence Listingsin International Patent Applications Under the PCTThe standard allows the applicant to draw up a singlesequence listing which is acceptable to all receivingOffices International Searching and Preliminary

Examining Authorities for the purposes of theinternational phase and to all designated and electedOffices for the purposes of the national phase TheInternational Searching Authority and theInternational Preliminary Examining Authority mayin some cases invite the applicant to furnish a listingcomplying with that standard The applicant mayalso be invited to furnish a listing in an electronicform (text) provided for in the PCT AdministrativeInstructions It is advisable for the applicant tosubmit a listing of the sequence in electronic form(text) if such a listing is required by the competentInternational Searching Authority or InternationalPreliminary Examining Authority together with theinternational application rather than to wait for aninvitation by the International Searching Authorityor International Preliminary Examining Authority

The electronic form (text) is not mandatory ininternational applications to be searched by theUnited States International Searching Authority orexamined by the United States InternationalPreliminary Examining Authority However if anelectronic form (text) of a sequence listing is notprovided a search or examination will be performedonly to the extent possible in the absence of theelectronic form (text) The US sequence rules (37CFR 1821 - 1825) and the PCT sequencerequirements are substantively consistent In thisregard full compliance with the requirements of theUS rules will generally ensure compliance with theapplicable PCT requirements However therequirements of 37 CFR 1821 through 37 CFR 1825are less stringent than the requirements of WIPOStandard ST25 See MPEP sect 2422 subsection IIMPEP sect 242203(a) subsection IV and MPEP sect242207 for information specific to filing sequencelistings in international applications

For a detailed discussion of the US sequence rulessee MPEP sectsect 2420 - 2429

The calculation of the international filing fee for aninternational application (PCT) including a sequencelisting filed via EFS-Web is determined based onthe type of sequence listing file A sequence listingfiled in an ASCII text file will not be included in thesheet count of the international application (PCT)A sequence listing filed in a PDF file will beincluded in the sheet count of the international

Rev 072015 October 20151800-29


application (PCT) Therefore the sheet count for anEFS-Web filed international application (PCT)containing both a PDF file and a text file sequencelisting will be calculated to include the number ofsheets of the PDF sequence listing

II TABLES RELATED TO SEQUENCE LISTINGS

Tables related to a sequence listing must be anintegral part of the description of the internationalapplication (PCT) and must not be included in thesequence listing part or the drawing part Such tableswill be taken into account when calculating theapplication sheet count and excess sheet fees maybe required When applicant submits tables relatedto a sequence listing in an international application(PCT) via EFS-Web the tables must be in a PDFfile If applicant submits tables related to a sequencelisting in a text file such tables will not be acceptedas part of the international application (PCT) Formore information see Sequence Listings and TablesRelated Thereto in International Applications Filedin the United States Receiving Office 1344 OG 50(July 7 2009) If applicant submits tables related toa sequence listing in a text file such tables will notbe accepted as part of the international application(PCT)

182801 Restoration of the Right of Priority[R-072015]

37 CFR 1452 Restoration of right of priority

(a) If the international application has an international filingdate which is later than the expiration of the priority period asdefined by PCT Rule 24 but within two months from theexpiration of the priority period the right of priority in theinternational application may be restored upon request if thedelay in filing the international application within the priorityperiod was unintentional

(b) A request to restore the right of priority in aninternational application under paragraph (a) of this section mustbe filed not later than two months from the expiration of thepriority period and must include

(1) A notice under PCT Rule 26 bis1(a) adding thepriority claim if the priority claim in respect of the earlierapplication is not contained in the international application

(2) The petition fee as set forth in sect 117(m) and

(3) A statement that the delay in filing the internationalapplication within the priority period was unintentional TheDirector may require additional information where there is aquestion whether the delay was unintentional

(c) If the applicant makes a request for early publicationunder PCT Article 21(2)(b) any requirement under paragraph(b) of this section filed after the technical preparations forinternational publication have been completed by theInternational Bureau shall be considered as not having beensubmitted in time

On April 1 2007 the regulations to the PCT wereamended to allow applicants with applications whichwere filed on or after that date and which were alsofiled after the expiration of the 12 month priorityperiod but within two months of the expiration ofthe priority period to request that the right of prioritybe restored provided that the failure to file theapplication within the priority period was in spite ofdue care or unintentional See PCT Rule 26 bis3Grantable requests for restoration of the right ofpriority must be filed within two months from the

Rev 072015 October 20151800-37


date of expiration of the priority period as definedby new PCT Rule 24 and must be accompanied by(i) the requisite fee as set forth in sect 117(m) (ii) anotice under PCT Rule 26 bis1(a) adding thepriority claim if the priority claim in respect of theearlier application is not contained in theinternational application and (iii) a statement thatthe delay in filing the international application withinthe priority period was unintentional The Directormay require additional information where there is aquestion whether the delay was unintentional If theapplicant makes a request for early publication underPCT Article 21(2)(b) any of requirements (i) (ii)or (iii) above which are filed after the technicalpreparations for international publication have beencompleted by the International Bureau shall beconsidered as not having been submitted in time

The International Bureau has indicated that it intendsto decide these matters under both the in spite of duecare and unintentional standards Therefore in viewof the fact that the USPTO only decides these mattersunder the unintentional standard applicants maywish to consider filing directly with the InternationalBureau as receiving Office instead of the UnitedStates Receiving Office in the situation whereapplicant desires to request restoration of the rightof priority under the in spite of due care standardApplicants may also request that an application beforwarded to the International Bureau for processingin its capacity as a receiving Office in accordancewith PCT Rule 194(a)(iii) in situations whereapplicants after the international application hasbeen filed realize that the application was filed afterthe expiration of the 12 month priority period butwithin two months of the expiration of the priorityperiod and where applicant desires to requestrestoration of the right of priority under the in spiteof due care standard However the United StatesReceiving Office may decline to forward theinternational application to the International Bureauunder PCT Rule 194(a)(iii) if substantial processingof the international application by the United StatesReceiving Office has occurred Applications filedwith or forwarded to the International Bureau musthave a foreign filing license

It should be noted that restoration of a right ofpriority to a prior application by the United StatesReceiving Office or by any other receiving Office

under the provisions of PCT Rule 26 bis3 will notentitle applicants to a right of priority to such priorapplication in a national stage application in anyoffice that has notified the International Bureauunder PCT Rule 26 bis3(j) and 49 ter1(g) of anincompatibility with its national law A full listingof the national offices that will not accept therestoration of the right of priority in the nationalstage may be found on WIPOrsquos website atwwwwipointpctentextsreservationsres_incomphtmlIn the United States a right of priority that has beenrestored under PCT Rule 26 bis3 during theinternational stage will be effective in the USnational stage See MPEP sect 189303(c)

It should also be noted that regardless of the PCTRule 26 bis3(j) and 49 ter1(g) status of anyparticular office the priority date will still governall PCT time limits including the thirty-monthperiod for filing national stage papers and fees under37 CFR 1495 PCT Article 2(ix) which definesldquopriority daterdquo for purposes of computing time limitscontains no limitation that the priority claim be valid

182802 Continuation orContinuation-in-Part Indication in theRequest [R-072015]

PCT Rule 4


411 Reference to Continuation or Continuation-in-Part orParent Application or Grant

(a) If

(ii) the applicant intends to make an indication underRule 49 bis1(d) of the wish that the international applicationbe treated in any designated State as an application for acontinuation or a continuation-in-part of an earlier applicationthe request shall so indicate and shall indicate the relevant parentapplication or parent patent or other parent grant

The Supplemental Box of the Request form shouldbe used where the applicant has an earlier pendingUnited States nonprovisional application orinternational application designating the US andwishes the later-filed international application to betreated as a continuation or continuation-in-part ofsuch earlier application To properly identify theparent application the specific reference must

1800-38Rev 072015 October 2015


identify the parent application by application numberand indicate the relationship to the parent application(ie ldquocontinuationrdquo or ldquocontinuation-in-partrdquo) Thespecific reference must also indicate the filing dateof the parent application if the parent application isan international application See 37 CFR 178(d)(2)

The inclusion of a proper reference to the parentapplication in the PCT Request form or the presenceof such reference on the front page of the publishedinternational application will satisfy the requirementin 37 CFR 178 for the presentation of a benefit claimin an application data sheet See 37 CFR 176(g) Insuch cases a reference to the parent application inan application data sheet would not be required inthe national stage application Furthermore inclusionof a proper reference to the parent application in thePCT Request form is also beneficial where applicantchooses to file a continuing application claimingbenefit under 35 USC 365(c) to the internationalapplication (ie a bypass application) rather thanentering the US national phase under 35 USC371 See MPEP sect 21102 which indicates the rightto rely on a prior application may be waived by anapplicant if a reference to the prior application is notincluded in the later-filed application

1832 License Request for Foreign FilingUnder the PCT [R-072015]

A license for foreign filing is not required to file aninternational application in the United StatesReceiving Office but may be required before theapplicant or the US Receiving Office can forwarda copy of the international application to a foreignpatent office the International Bureau or otherforeign authority (35 USC 368 37 CFR 51 and511) A foreign filing license to permit transmittalto a foreign office or international authority is notrequired if the international application does notdisclose subject matter in addition to that disclosedin a prior US national application filed more than6 months prior to the filing of the internationalapplication (37 CFR 511(a)) In all other instances(direct foreign filings outside the PCT or filings ina foreign receiving Office) the applicant shouldpetition for a license for foreign filing (37 CFR 512)and if appropriate identify any additional subjectmatter in the international application which was notin the earlier US national application (37 CFR514(c))

If no petition or request for a foreign filing licenseis included in the international application and it isclear that a license is required because of thedesignation of foreign countries and the time atwhich the Record Copy must be transmitted it iscurrent Office practice to construe the filing of suchan international application to include a request fora foreign filing license If the license can be grantedit will be issued without further correspondence Ifno license can be issued or further information isrequired applicant will be contacted The automaticrequest for a foreign filing license does not apply tothe filing of a foreign application outside the PCT

of assistance in determining that the claimedinvention is or is not new and that the claimedinvention does or does not involve an inventive step(ie that it is or is not obvious) and if the makingavailable to the public occurred prior to theinternational filing date for the purposes of theinternational search report and prior to the earliestvalidly claimed priority date for the purposes of thewritten opinion of the International SearchingAuthority For further details see PCT Rules 3343 bis1(b) and 64

A written disclosure that is a document is regardedas made available to the public if at the relevantdate it was possible for members of the public togain access to the content of the document and toacquire possession of the content of the documentand there was no bar of confidentiality restrictingthe use or dissemination of knowledge gainedthereby Where the document only provides themonth or the year but not the specific date whichthe document was made available to the public thecontent of the document is presumed to have beenmade available to the public on the last day of thatmonth or that year respectively unless evidence isprovided to prove otherwise

Prior art disclosure on the Internet or on an onlinedatabase is considered in the same manner as otherforms of written disclosure Information disclosedon the Internet or an online database is consideredto be publicly available as of the date the disclosurewas publicly posted Where the examiner obtains anelectronic document that establishes the publicationdate for the Internet disclosure heshe should makea printout of this document which must mentionboth the URL of the relevant Internet disclosure andthe date of publication of that relevant Internetdisclosure The examiner must then cite this printoutin the international search report as an ldquoLrdquo documentand cite the relevant Internet disclosure accordingto the relevance of its content (ldquoXrdquo ldquoYrdquo ldquoArdquo) andaccording to the date as established (ldquoXrdquo ldquoYrdquo ldquoArdquoldquoPXrdquo ldquoPYrdquo ldquoPArdquo ldquoErdquo etc) See MPEP sect184401 subsection VII Where the examiner isunable to establish the publication date of therelevant Internet disclosure and it is relevant to theinventive step andor novelty of the claimedinvention heshe should cite it in the internationalsearch report as a category ldquoLrdquo document for those

claims which it would have affected if it werepublished in time giving the date the document wasprinted out as its publication date

Examiners are also encouraged to cite prior art thatmight be of assistance in determining whether otherrequirements are fulfilled such as sufficient supportof the claims by the description and industrialapplicability The examiner should also note anydocuments that may be of importance for otherreasons such as documents putting doubt upon thevalidity of any priority claimed documentscontributing to a better or more correct understandingof the claimed invention and documents illustratingthe technological background but the examinershould not spend time in searching for thesedocuments nor the consideration of such mattersunless there is a special reason for doing so in aparticular case Documents which do not qualify asprior art because they post-date the claimed inventionmay nevertheless be cited to show a universal factsuch as characteristics or properties of a material ora specific scientific fact or to show the level ofordinary skill in the art Furthermore examinersmust recognize that different designated Offices mayhave different definitions of what is the effectivedate of prior art Accordingly when performing thesearch examiners should be mindful to pick out andselect for citation where appropriate prior art whichmay be relevant in offices other than the one inwhich they are situated However the examiner neednot expand the search beyond the standard searchparameters to discover such art Where the searchhas been performed and such potentially relevantprior art has been identified examiners areencouraged to for example cite all relevant artpublished prior to the international filing date evenif that art and the international application underconsideration have common applicants andorinventors As such if the examiner is basing theinternational search on a prior search performed ina prior related US national application it may benecessary for the examiner to review the prior artpublished within the time period of the one yearpreceding the filing date of the prior US applicationfor any written disclosures based on the applicantrsquosown work that may have been published within thattime period Any such documents are consideredprior art in an international application and are citedon the international search report even though they

Rev 072015 October 20151800-53


do not meet the definition of prior art in the priorUS national application A further objective of theinternational search is to avoid or at least minimizeadditional searching at the national stage

The international search is made on the basis of theclaims with due regard to the description and thedrawings (if any) contained in the internationalapplication (PCT Article 15(3)) and should coverthe entire subject matter to which the claims aredirected or to which they might reasonably beexpected to be directed after they have been amended(PCT Rule 333(b))

The relevant date for the purpose of consideringprior art for the purposes of establishment of thewritten opinion of the International SearchingAuthority is defined in PCT Rule 641(b) as theinternational filing date or where the internationalapplication contains a claim for priority the dateprovided in PCT Rule 641(b)(ii) - (iii) See MPEPsect 187801(a)

In establishment of the written opinion whendetermining whether there is inventive step accountshould be taken of what the applicant acknowledgesin hisher description as known Such admissionsshould be regarded as correct and used whenconsidering whether the claimed invention lacksnovelty andor inventive step where appropriate

A nonwritten disclosure such as an oral disclosureuse exhibition or other means of disclosure is notrelevant prior art for the purposes of the internationalsearch unless it is substantiated by a writtendisclosure made available to the public prior to theinternational filing date and it is the writtendisclosure which constitutes the prior art Howeverif the date on which the written disclosure was madeavailable to the public was on or after the filing dateof the international application under considerationthe search report should separately mention that factand the date on which the written disclosure wasavailable even though such a written disclosure doesnot meet the definition of relevant prior art in theinternational phase so long as the non-writtendisclosure was made available to the public on a dateprior to the international filing date since such anon-written disclosure may be considered to be prior

art under national law in the national phase See PCTRules 331(b) 642 and 709

DOCUMENTS AND DATABASES SEARCHED BYTHE INTERNATIONAL SEARCHINGAUTHORITY

The International Searching Authority must endeavorto discover as much of the relevant prior art as itsfacilities permit (PCT Article 15(4)) and in anycase must consult the so-called ldquominimumdocumentationrdquo (PCT Rule 34)

Even though completeness should be the ultimategoal of the international search this goal may attimes be difficult to obtain because of such factorsas text search limitations and the inevitableimperfections of any classification system and itsimplementation The examiner therefore consultsthe appropriate minimum documentation and themost relevant search resources for the technologyincluding databases listed in the US SearchGuidance index (available through the USPTOIntranet website) and organizes the search effortand utilizes the search time in such a manner as toreduce to a minimum the possibility of failing todiscover existing highly relevant prior art such asart that fully anticipates any claims

When conducting the search it may be necessary tomake use of the Internet as a search tool Where theinternational application has not yet been publishedat the time of the search there exists the danger thatsearch terms used in the search on non-secureInternet search engines or in databases available onthe Internet may be observed by third partiesAccordingly all websites must be treated asnon-secure unless the Office has a commercialarrangement with a service provider in order tomaintain confidentiality and a secure connection tothat website Consequently extreme caution mustbe exercised when using the Internet as a search toolwhere (as in most cases) the international applicationhas not yet been published Where a relevantdatabase is accessible via the Internet but analternative secure connection to the same databaseis accessible the secure connection must be usedWhere no secure connection to a database on theInternet is available the search may be conductedon the Internet using generalized search terms

file one if the subject matter of the application fallsinto one of the above mentioned areas If he or shestill does file the International Searching Authoritymay declare that it will not establish an internationalsearch report Accordingly applicant should takeinto consideration which International SearchingAuthority (eg European Patent Office) he or sheselects to conduct the international search It is tobe noted nevertheless that the lack of theinternational search report in such case will not havein itself any influence on the validity of theinternational application and the latterrsquos processingwill continue including its communication to thedesignated Offices

184303 No Search Required if Claims AreUnclear [R-082012]

If the International Searching Authority considersthat the description the claims or the drawings failto comply with the prescribed requirements to suchan extent that a meaningful search could not becarried out it may declare that it will not establisha search report (PCT Article 17(2)(a)(ii)) Furtherfor applications having an international filing dateon or after January 1 2004 if the InternationalSearching Authority considers that the descriptionclaims or drawings are so unclear or the claims areso inadequately supported by the description that nomeaningful opinion can be formed on the noveltyinventive step (non-obviousness) or industrialapplicability of the claimed invention the Authorityshall not go into these issues in its written opinionwith regard to the claims so affected (PCT Rules43 bis1(b) and 661(e)) For example the examinermay determine that a meaningful search cannot becarried out or that no meaningful opinion can beformed in certain cases where a nucleotide andoramino acid sequence listing is not furnished inaccordance with the prescribed standard or in acomputer readable form See AdministrativeInstructions Section 513(c) and MPEP sect 1848Further the examiner may determine that ameaningful search cannot be carried out or that no

meaningful opinion can be formed for impropermultiple dependent claims (see PCT Rule 64(a))

184304 Procedure for Claims Not RequiredTo Be Searched and for Claims That AreUnclear [R-072015]

The International Searching Authority (ISA) maydeclare that a meaningful search cannot be carriedout with respect to some of the claims only andorthat only certain claims relate to subject matter whichthe ISA is not required to and has decided not tosearch Where only some of the claims will not besearched the ISA searches the remaining claims ofthe international application Any unsearched claimsand the reasons why those claims have not beensearched are indicated in Box No II of theinternational search report (Form PCTISA210)

If the examiner determines that none of the claimswill be searched the examiner declares that nosearch report will be established using FormPCTISA203 The lack of the international searchreport will not in itself have any influence on thevalidity of the international application and thelatterrsquos processing will continue including itscommunication to the designated Offices

If the international application cites a document thatis not published or otherwise not accessible to theISA and the document appears essential to a correctunderstanding of the invention to the extent that ameaningful international search would not bepossible without knowledge of the content of thatdocument the ISA may postpone the search andrequest that the applicant first provide first a copyof the document if possible to do so within the timelimits for the preparation of the international searchreport of the ISA under the PCT If no copy of thedocument is received the ISA should first attemptto carry out the international search and then ifnecessary indicate that no meaningful search couldbe carried out in total or that the search needed tobe restricted

The ISA establishes the written opinion of theInternational Searching Authority (FormPCTISA237) at the same time it establishes eitherthe international search report (Form PCTISA210)or the declaration of non-establishment of the

1800-56Rev 072015 October 2015

A Box 1a ndash Language

In most circumstances the first box under box 1a ischecked indicating that the search is carried out onthe basis of the international application in thelanguage in which it was filed Alternatively thesecond box under box 1a is checked and anindication of English made when the search is onthe basis of a translation of the internationalapplication into English

B Box 1b ndash Rectification of an Obvious Mistake

Where the application includes the rectification ofan obvious mistake authorized by or notified to the

1800-58Rev 072015 October 2015


International Searching Authority under PCT Rule91 box 1b of the first sheet is checked Theauthorization or notification will generally beindicated on a Notification of Decision ConcerningRequest for Rectification (Form PCTRO109 orPCTISA217) (see MPEP sect 1836)

C Box 1c And Box No I ndash Nucleotide andor AminoAcid Sequence Listings

Where the application discloses any nucleotideandor amino acid sequence box 1c of the first sheetis checked and Box No I (appearing onldquocontinuation of first sheet (1)rdquo) indicates in item1a the sequence listing format (that is whether inpaperimage or electronic form (text)) and in item1b the time of filingfurnishing (that is whethercontained in the international application as filedfiled together with the international application inelectronic form (text) andor furnished subsequentlyto the International Searching Authority (ISA) forpurposes of search)

If more than one version or copy of the sequencelisting is filed item 2 indicates whether the applicanthas provided the required statement indicating thatthe information in the subsequent or additionalcopies is identical to that in the application as filedor does not go beyond the application as filed asappropriate Item 3 indicates any additionalcomments

II BOX 2 AND BOX NO II ndash LIMITATION OF THESUBJECT OF THE INTERNATIONAL SEARCH

The report indicates whether any claims areunsearchable for any of the reasons indicated belowIf any such limitations of the subject of the searchare applied the claims in respect of which a searchhas not been carried out are identified and thereasons for this are indicated The three categorieswhere such limitations may arise are

(A) claims drawn to subject matter not requiredto be searched by the International SearchingAuthority (see MPEP sect 184302)

(B) claims in respect of which a meaningfulsearch cannot be carried out (see MPEP sect 184303)and

(C) multiple dependent claims which do notcomply with PCT Rule 64(a) (see MPEP sect 184303)

Where claims are not searched for any of the reasonsidentified in (A)-(C) above box 2 of the first sheetof the international search report is checked Inaddition Box No II of the international search report(on ldquocontinuation of first sheet (2)rdquo) is completedgiving the details

III BOX 3 AND BOX NO III ndash LACK OF UNITYOF THE CLAIMED INVENTION

The report indicates whether the search is limiteddue to a lack of unity of invention If unity is lackingthe claims in respect of which a search has not beencarried out are identified and the reasons for this areindicated

Where lack of unity has been found (see MPEPsect 1850) box 3 of the first sheet of the internationalsearch report is checked In addition Box No III ofthe international search report (on ldquocontinuation offirst sheet (2)rdquo) is completed irrespective of whetheran invitation to pay additional search fees has issuedThe search report indicates the separate inventionsclaimed in the application whether additional searchfees were requested and paid and which claims weresearched It also indicates whether any additionalsearch fees were accompanied by a protest

An explanation of the separate inventions is enteredin the appropriate area in Box No III (see MPEP sect1850)

If applicant paid all the required additional searchfees for additional inventions the examiner shouldcheck item 1 under Box No III indicating that theinternational search report covers all searchableclaims

If the examiner did not invite payment of additionalsearch fees item 2 should be checked under BoxNo III and the international search report will coverall searchable claims

If in response to a lack of unity of inventionapplicant paid only some of the required additionalsearch fees for additional inventions the examinershould check item 3 under Box No III and indicate

Rev 072015 October 20151800-59


the claims for which fees were paid and thereforecovered by the international search

If the international search report is based on theinvention first mentioned in the claims the examinershould check item 4 under Box No III and indicatethe claims limited to the first mentioned inventionthat are covered by the international search report

Regarding the three boxes indicating a Remark onProtest the first box would be checked if thepayment of any additional search fees isaccompanied by a protest The second box wouldnot be checked since the ISAUS does not require aprotest fee The third box would be checked if thepayment of any additional search fees is notaccompanied by a protest See MPEP sect 1850subsection X for a discussion of protest procedure

IV TITLE ABSTRACT AND FIGURE FORPUBLICATION

The international application must contain anabstract and a title The examiner considers theabstract (together with the title of the invention andthe figure of the drawings to be published with theabstract) in relation to the requirements of theRegulations under the PCT The examiner indicatesapproval or amendment of the title of the inventionthe text of the abstract and the selection of the figurethat is to accompany the abstract in items 4 to 6 ofthe first sheet of the international search report

Authority that it has invited the applicant to correct such defectthe International Searching Authority shall proceed with theinternational search unless and until it receives notification thatthe said application is considered withdrawn

372 Establishment of Title

If the international application does not contain a title and theInternational Searching Authority has not received a notificationfrom the receiving Office to the effect that the applicant hasbeen invited to furnish a title or if the said Authority finds thatthe title does not comply with Rule 43 it shall itself establisha title Such title shall be established in the language in whichthe international application is to be published or if a translationinto another language was transmitted under Rule 231(b) andthe International Searching Authority so wishes in the languageof that translation

The title must be short and precise (preferably fromtwo to seven words in English or when translatedinto English) Furthermore the title should clearlyand concisely state the technical designation of theinvention In this regard the following should betaken into account

(A) personal names or trade names or similarterms of non-technical nature which do not serve toidentify the invention should not be used

(B) the abbreviation ldquoetcrdquo being vague shouldnot be used and should be replaced by an indicationof what it is intended to cover

(C) titles such as ldquoMethodrdquo ldquoApparatusrdquoldquoChemical Compoundsrdquo alone or similar vague titlesdo not clearly state the technical designation of theinvention and should not be used

In general the examiner is required to draft a newtitle if the applicant failed to provide a title or if thetitle is deficient because it does not comply with therequirements of PCT Rule 43 The examiner is notrequired to gain the applicantrsquos approval of the newtitle established by the examiner

On the first sheet of the international search reportthe examiner indicates the title text is approved (thefirst box under Box 4) or has been established (thesecond box under Box 4)

382 Establishment of Abstract

If the international application does not contain an abstract andthe International Searching Authority has not received anotification from the receiving Office to the effect that theapplicant has been invited to furnish an abstract or if the saidAuthority finds that the abstract does not comply with Rule 8it shall itself establish an abstract Such abstract shall beestablished in the language in which the international applicationis to be published or if a translation into another language wastransmitted under Rule 231(b) and the International SearchingAuthority so wishes in the language of that translation

383 Modification of Abstract

The applicant may until the expiration of one month fromthe date of mailing of the international search report submit tothe International Searching Authority

(i) proposed modifications of the abstract or

(ii) where the abstract has been established by theAuthority proposed modifications of or comments on thatabstract or both modifications and comments

and the Authority shall decide whether to modify the abstractaccordingly Where the Authority modifies the abstract it shallnotify the modification to the International Bureau

In general the examiner will have to establish a newabstract if the applicant did not provide an abstractor if the abstract does not comply with PCT Rule 8In determining the definitive contents of the abstractor establishing the text of the abstract anew whereit is missing the examiner should take intoconsideration the fact that the abstract is merely foruse as technical information and in particular mustnot be used for the purpose of interpreting the scopeof the protection sought The abstract constitutes anefficient instrument for the purpose of assisting thescientist engineer or researcher in searching in theparticular technical field and should in particularmake it possible to assess whether there is need forconsulting the international application itself WIPOguidelines for the preparation of abstracts are foundin WIPO Standard ST12A which is available from

In considering the adequacy of the applicantrsquosabstract and figure because of practical difficultiesexperienced by the International Bureau withpublication examiners should have particular regardto the following

(A) It is important that the abstract be as conciseas the disclosure permits (preferably 50 to 150 wordsif it is in English or when translated into English)Within this constraint the abstract must provide asummary of the technical information about thedisclosure as contained in the description claimsand drawings It should be drafted so as to serve asan efficient scanning tool for searching purposes inthe art

(B) Phrases should not be used which can beimplied such as ldquoThis disclosure concernsrdquo ldquoTheinvention defined by this disclosurerdquo and ldquoThisinvention relates tordquo

(C) Only one figure should normally be selectedunless this would lead to inadequate disclosure Theinclusion of more than two figures should not beconsidered except in extreme circumstances wherenecessary information cannot be otherwise conveyedWhere none of the figures is considered useful forthe understanding of the invention (even where theapplicant has suggested a figure) no figure shouldbe selected

(D) Abstracts may be incomprehensible if thenumerals of the selected figure(s) do not correspondwith those in the abstract Thus this should beavoided

(E) An absence of reference numbers on thefigures must be accepted as the examiner has nomechanism to initiate their addition

(F) Each main technical feature mentioned inthe abstract and illustrated by a drawing should befollowed by a reference sign placed betweenparentheses

In box 5 of the first sheet of the international searchreport the examiner indicates approval of the textof the abstract by checking the first box When thetext of the abstract is missing or defective the secondbox is checked and the new abstract is establishedby entering the text of the new abstract The defect

or reason for establishing the new abstract shouldbe indicated eg too long or missing

The applicant may submit modifications of theabstract until the expiration of one month from thedate of mailing of the search report If the examinerestablishes a new abstract the applicant may proposemodifications of andor comment on the newabstract after it has been established in theinternational search report The applicant is allowedone month from the date of mailing of theinternational search report to respond to theexaminerrsquos abstract in the report If the applicantdoes comment the examiner takes the applicantrsquoscomments into consideration It is not necessary forthe examiner to reply to the applicantrsquos commentseven if adverse If the examiner decides to amendthe abstract established in the international searchreport based on the proposed modifications andorcomment the International Bureau and the applicantare notified using Form PCTISA205 See PCT Rule383 and Administrative Instructions Section 515

When indicating the figure to be published theapplicantrsquos suggestion is found in Box No IX of therequest (Form PCTRO101) Where none of thefigures is considered useful for the understanding ofthe abstract this is indicated at the appropriate box(box 6b of the first sheet of Form PCTISA210)When no drawings accompany the application noneof the boxes are checked Otherwise box 6a ischecked and the reason for selecting the figure to bepublished is indicated ie as suggested by theapplicant as selected by the examiner because eitherthe applicant failed to suggest a figure in Box NoIX of Form PCTRO101 or the figure bettercharacterizes the invention It is not recommendedto select more than one figure however if it isnecessary to do so then the wording of the formshould be changed to reflect the change from singlecase to plural case For example ldquofigurerdquo is changedto ldquofiguresrdquo ldquoisrdquo to ldquoarerdquo and ldquo Nordquo to ldquoNosrdquo

V BOX A - CLASSIFICATION OF SUBJECTMATTER

The International Searching Authority assignsobligatory International Patent Classification (IPC)symbols in accordance with the rules as set forth inthe Guide to the IPC and in the IPC itself (using the

1800-62Rev 072015 October 2015


edition of the IPC in force at the time) whereby thetechnical subject of the invention of the applicationis identified The International Searching Authoritythen records the International Patent Classificationand the patent classification as required by theISAUS in Box A of the second sheet of theinternational search report The IPC Guide can beaccessed via the Patent Examinerrsquos Toolkit underClassification Tools or via WIPOrsquos website(wwwwipointclassificationsipcen)

VI BOX B - RECORDING THE SEARCH

The examiner records the search history in Box Bof the second sheet of the international search reportIn recording the search history of the internationalsearch the examiner lists the classificationidentification of the fields searched Examiners arealso encouraged to record the search history insufficient detail to allow examiners of national stageapplications to fully interpret and rely upon theinternational search This includes recording thedetails of any patent and non-patent literaturesearches as well as searches conducted on theInternet

Where the international search report is entirely orpartly based on a previous search made for anapplication relating to a similar subject the previousapplication number and the relevant search historyconsulted for this previous search is whereappropriate identified as having been consulted forthe international application in question except inthose instances where the details of an earlier searchcannot be ascertained or whenever it is impracticalto record the full details of the earlier search In thelater case a summary of the earlier search shouldbe included Where the previous application has beenpublished this information is recorded in theinternational search report

The USPTO in its capacity as the InternationalSearching Authority makes a separate detailed searchhistory of record in the applications These searchhistories are mailed to applicants with theinternational search report

VII BOX C - DOCUMENTS CONSIDERED TO BERELEVANT

The completion of Box C of the second sheet of theinternational search report can be considered ashaving three components These are (A) the citationcategory (B) the citation of the document togetherwith identification of the relevant passages whereappropriate and (C) the identification of relevantclaim numbers The citation of multiple documentsshowing the same inventive elements should be keptto a minimum Further when citing a document theexaminer should clearly indicate which portions ofthe document are most relevant

A Citation Category

Documents which are cited are given a categoryindication by way of an alphabetic character detailsof which are given in PCT AdministrativeInstructions Sections 505 and 507 and below Thecategories for citations are also explained under theldquodocuments considered to be relevantrdquo section ofthe report A category should always be indicatedfor each document cited Where neededcombinations of different categories are possible

1 Particularly Relevant Documents

Where a document cited in the international searchreport is particularly relevant it is indicated by theletters ldquoXrdquo or ldquoYrdquo Category ldquoXrdquo is applicable wherea document is such that when taken alone a claimedinvention cannot be considered novel or where adocument is such that when considered in light ofcommon general knowledge a claimed inventioncannot be considered to involve an inventive stepCategory ldquoYrdquo is applicable where a document issuch that a claimed invention cannot be consideredto involve an inventive step when the document iscombined with one or more other documents of thesame category such combination being obvious toa person skilled in the art

2 Documents Defining the State of the Art and NotPrejudicing Novelty or Inventive Step

Where a document cited in the international searchreport represents state of the art and is not prejudicial

Rev 072015 October 20151800-63


to the novelty or inventive step of the claimedinvention it is indicated by the letter ldquoArdquo

3 Documents Which Refer to a Non-WrittenDisclosure

Where a document cited in the international searchreport refers to a non-written disclosure referred toin PCT Rule 331(b) the letter ldquoOrdquo is enteredExamples of such disclosures include conferenceproceedings The document category ldquoOrdquo is alwaysaccompanied by a symbol indicating the relevanceof the document for example ldquoOXrdquo ldquoOYrdquo orldquoOArdquo

4 Intermediate Documents

Documents published on dates falling between thedate of filing of the application being searched andthe date of priority claimed or the earliest priorityif there is more than one (see PCT Article 2(xi)(b))are denoted by the letter ldquoPrdquo The letter ldquoPrdquo is alsogiven to a document published on the very day ofthe earliest date of priority of the patent applicationunder consideration The document category ldquoPrdquo isalways accompanied by a symbol indicating therelevance of the document for example ldquoPXrdquoldquoPYrdquo or ldquoPArdquo

5 Documents Relating to the Theory or PrincipleUnderlying the Invention

Where any document cited in the search report is adocument that may be useful for a betterunderstanding of the principle or theory underlyingthe invention or is cited to show that the reasoningor the facts underlying the invention are incorrectit is indicated by the letter ldquoTrdquo

6 Potentially Conflicting Patent Documents

Any patent document bearing a filing or priority dateearlier than the filing date of the application searched(not the priority date) but published on or later thanthat date and the content of which would constituteprior art relevant to novelty (PCT Article 33(2)) isindicated by the letter ldquoErdquo (see PCT AdministrativeInstructions Section 507(b) and PCT Rule 331(c))

7 Documents Cited in the Application

When the search report cites documents alreadymentioned in the description of the patent applicationfor which the search is carried out such documentsmay be identified on the search report by the wordingldquocited in the applicationrdquo under the cited document

8 Documents Cited for Other Reasons

Where in the search report any document is cited forreasons other than those referred to in the foregoingparagraphs (in particular as evidence) for example

(A) a document which may throw doubt on apriority claim (Article 4(C)(4) of the ParisConvention) or

(B) a document cited to establish the publicationdate of another citation

the document is indicated by the letter ldquoLrdquo Briefreasons for citing the document should be givenDocuments of this type need not be indicated asrelevant to any particular claims However wherethe evidence that they provide relates only to certainclaims (for example the ldquoLrdquo document cited in thesearch report may invalidate the priority in respectof certain claims and not others) then the citationof the document should refer to those claims

B Citation of the Documents

Identification of any document should be madeaccording to WIPO Standard ST14 (see PCTAdministrative Instructions Section 503) For ldquoArdquocitations it is not necessary to indicate the relevantclaims unless there is good reason to do so forexample where there is a clear lack of unity a priori(see MPEP sect 1850) and the citation is relevant onlyto a particular claim or group of claims or when theclaims meet the criteria of novelty inventive stepand industrial applicability under PCT Article 33(2)to (4) and the ldquoArdquo category citations represent themost relevant prior art The box on the second sheetof Form PCTISA210 entitled ldquoFurther documentslisted are in the continuation of Box Crdquo is checkedif a continuation sheet is used to list additionaldocuments that will not fit in the space provided inBox C

1800-64Rev 072015 October 2015


C Relationship Between Documents and Claims

Each citation should include a reference to the claimsto which it relates (see PCT AdministrativeInstructions Section 508) If necessary variousrelevant parts of the document cited should each berelated to the claims in like manner (with theexception of ldquoLrdquo documents and ldquoArdquo documents)It is also possible for the same document to representa different category with respect to different claimsFor example

WO1990001867 A (WIDEGREN LARS (SE)) 8March 1990 (08-03-1990) figures 1 and 2

X 1

Y 2-5

A 6-10

The above example means that Figures 1 and 2 ofthe cited document disclose subject matter whichprejudices the novelty or inventive step of claim 1which prejudices the inventive step of claims 2-5when combined with another document cited in thesearch report and which represents non-prejudicialstate of the art for the subject matter of claims 6-10

VIII FINALIZATION OF THE SEARCH REPORT

The identification of the International SearchingAuthority which established the international searchreport and the date of actual completion that is thedate on which the report was drawn up are indicatedat the bottom of the second sheet of the internationalsearch report The international search report willbe accompanied by a transmittal letter (FormPCTISA220) indicating the date the search reportwas mailed to the applicant See MPEP sect 184502

Pursuant to PCT Rule 438 the international searchreport must indicate the name of the officer of theInternational Searching Authority responsible forthe report ie the ldquoauthorized officerrdquo Anldquoauthorized officerrdquo is the person who actuallyperformed the search work and prepared the searchreport or another person who was responsible forsupervising the search See PCT AdministrativeInstructions Section 514 Thus an examiner neednot have signatory authority in order to be named asan authorized officer on the search report Howeverthe ldquofile copyrdquo of the search report must be signedby an examiner having at least partial signatoryauthority

The international search report should be mailedwithin 3 months of receipt of the search copy orwithin 9 months from the priority date whicheveris later

and necessary to the claimed invention the examinermust indicate the format of the material (ie onpaperimage or in electronic form (text)) and thetime of filingfurnishing (ie contained in theinternational application as filed filed together withthe international application in electronic form (text)andor furnished subsequently to the ISA for thepurposes of the search) If more than one version orcopy of the sequence listing is filed the examinermust indicate in item 4 whether the applicant hasprovided the required statement indicating that theinformation in the subsequent or additional copiesare identical to that in the application as filed or doesnot go beyond the application as filed as appropriateItem 5 is available for providing any additionalcomments

II BOX NO II mdash PRIORITY

Box No II of Form PCTISA237 is to informapplicant of the status of a request for priorityWhere one or more citations of the internationalsearch report were published after the earliest prioritydate the validity of that earliest priority date requireschecking Where the priority document is one whichis in the records of the ISA it should be obtainedfrom those records If a copy of the prioritydocument is not available before preparation of thewritten opinion of the ISA because it has not yetbeen provided by the applicant and if that earlierapplication was not filed with that Authority in itscapacity as a national Office or the priority documentis not available to that Authority from a digitallibrary in accordance with the AdministrativeInstructions the written opinion of the ISA may beestablished as if the priority had been validlyclaimed

If the examiner needs a copy of a foreign prioritydocument the copy will be supplied on request tothe International Bureau (IB) unless the IB has notyet received the priority document in which casethe examiner may invite the applicant to furnish sucha copy See PCT Rule 667(a) The examiner mayconsult with the Technology Center QualityAssurance Specialist or PCT Special ProgramExaminer regarding requesting a copy of the prioritydocument from the IB If the priority document isnot in English the examiner may invite the applicantto furnish a translation of the priority document

within two months of the invitation See PCT Rule667(b) Box No II item 3 ldquoAdditionalObservationsrdquo may be used to invite applicant tosupply a copy of the priority document andortranslation Preparation of the written opinion by theInternational Searching Authority should not bedelayed to await a response to the invitation Thewritten opinion of the ISA will ordinarily beestablished as if the priority claim had been validlyclaimed even though the copy andor translation hasnot been furnished However failure to timelyfurnish a copy of the priority document andortranslation may result in any further written opinionor international preliminary examination report ofthe International Preliminary Examining Authoritybeing established as if the priority had not beenclaimed

If applicant fails to furnish a copy or translation ofthe earlier application whose priority has beenclaimed check item 1 and then check the first boxof the subsection if applicant failed to furnish a copyof the earlier application whose priority has beenclaimed and check the second box of the subsectionif applicant failed to furnish a translation of theearlier application whose priority has been claimed

When the claim for priority has been found invalid(eg the notification under PCT Rule 26 bis2(b)has been provided or all claims are directed toinventions which were not described and enabledby the earlier application) check item 2 in Box IIand indicate why the claim for priority has beenfound invalid following item 3 ldquoAdditionalobservationsrdquo

III BOX NO III mdash NON-ESTABLISHMENT OFOPINION ON NOVELTY INVENTIVE STEP ANDINDUSTRIAL APPLICABILITY

Box No III of Form PCTISA237 is intended tocover situations where some or all claims of anapplication are so unclear or inadequately supportedby the description that the question of noveltyinventive step (nonobviousness) and industrialapplicability cannot be considered or where theinternational application or claims thereof relate tosubject matter for which it is not required to establisha written opinion concerning novelty inventive step

Rev 072015 October 20151800-71


and industrial applicability or where no internationalsearch report has been established for the claims

If some or all of the claims of an application relateto subject matter for which it is not required toestablish a written opinion concerning noveltyinventive step and industrial applicability check theappropriate box indicate which claims relate to thatsubject matter and specify the reasons eg impropermultiple dependent claims that fail to comply withPCT Rule 64

If some or all of the claims of an application are sounclear that no meaningful opinion could be formedcheck the appropriate box indicate which claims areunclear and specify the reasons

If some or all of the claims are so inadequatelysupported by the description that no meaningfulopinion could be formed check the appropriate box

If no international search report has been establishedfor certain claims check the appropriate box andindicate the claim numbers

If the nucleotide andor amino acid sequence listingdoes not comply with Annex C of the AdministrativeInstructions the examiner must indicate whether thewritten form andor the electronic form (text) is notin compliance and the reason for thenon-compliance

IV BOX NO IV mdash LACK OF UNITY OFINVENTION

Box No IV of Form PCTISA237 should be usedby the examiner to notify applicant that lack of unityhas been found by checking item 1 and one of thefour boxes under item 1

If applicant paid additional fees for additionalinventions the examiner should check the first boxunder item 1

If the additional fees were paid under protest theexaminer should check the second box under item1

Regarding the third box since the ISAUS does notrequire a protest fee this box would not be checked

If the search report is based on the first mentionedinvention (no additional search fees were paid) theexaminer should check the fourth box under item 1

Item 2 of Box No IV is to be completed if theexaminer determines that unity of invention islacking but chooses not to invite the applicant toagree to a search limited to the first mentionedinvention or pay additional fees

If a lack of unity exists the examiner would markthe second box under item 3 However since thereasons for the lack of unity have already been setforth on the simultaneously issued internationalsearch report the examiner can simply state that thereason the requirement of unity of invention is notcomplied with is set forth in the international searchreport The first box under item 3 would never bemarked

Item 4 is used by the examiner to indicate whichparts of the application form the basis of the opinionafter the lack of unity of invention has beenexplained The first box should be checked whenthe opinion is established for all parts Otherwisethe second box is checked and the relevant claimsidentified

37 CFR 1475 Unity of invention before the InternationalSearching Authority the International PreliminaryExamining Authority and during the national stage

(a) An international and a national stage application shallrelate to one invention only or to a group of inventions so linkedas to form a single general inventive concept (ldquorequirement ofunity of inventionrdquo) Where a group of inventions is claimed inan application the requirement of unity of invention shall befulfilled only when there is a technical relationship among thoseinventions involving one or more of the same or correspondingspecial technical features The expression ldquospecial technicalfeaturesrdquo shall mean those technical features that define acontribution which each of the claimed inventions consideredas a whole makes over the prior art

(b) An international or a national stage applicationcontaining claims to different categories of invention will beconsidered to have unity of invention if the claims are drawnonly to one of the following combinations of categories

(1) A product and a process specially adapted for themanufacture of said product or

(2) A product and a process of use of said product or

(3) A product a process specially adapted for themanufacture of the said product and a use of the said productor

(4) A process and an apparatus or means specificallydesigned for carrying out the said process or

(c) If an application contains claims to more or less thanone of the combinations of categories of invention set forth inparagraph (b) of this section unity of invention might not bepresent

(d) If multiple products processes of manufacture or usesare claimed the first invention of the category first mentionedin the claims of the application and the first recited inventionof each of the other categories related thereto will be consideredas the main invention in the claims see PCT Article 17(3)(a)and sect 1476(c)

Rev 072015 October 20151800-87


(e) The determination whether a group of inventions is solinked as to form a single general inventive concept shall bemade without regard to whether the inventions are claimed inseparate claims or as alternatives within a single claim

I THE REQUIREMENT FOR ldquoUNITY OFINVENTIONrdquo

Any international application must relate to oneinvention only or to a group of inventions so linkedas to form a single general inventive concept (PCTArticle 3(4)(iii) and 17(3)(a) PCT Rule 131 and37 CFR 1475) Observance of this requirement ischecked by the International Searching Authorityand may be relevant in the national (or regional)phase

The decision in Caterpillar Tractor Co vCommissioner of Patents and Trademarks 650 FSupp 218 231 USPQ 590 (ED Va 1986) held thatthe Patent and Trademark Office interpretation of37 CFR 1141(b)(2) as applied to unity of inventiondeterminations in international applications was notin accordance with the Patent Cooperation Treatyand its implementing regulations In the Caterpillarinternational application the USPTO acting as anInternational Searching Authority had held lack ofunity of invention between a set of claims directedto a process for forming a sprocket and a set ofclaims drawn to an apparatus (die) for forging asprocket The court stated that it was an unreasonableinterpretation to say that the expression ldquospecificallydesignedrdquo as found in former PCT Rule 132(ii)means that the process and apparatus have unity ofinvention if they can only be used with each otheras was set forth in MPEP sect 80605(e)

Therefore when the Office considers internationalapplications as an International Searching Authorityas an International Preliminary Examining Authorityand during the national stage as a Designated orElected Office under 35 USC 371 PCT Rule 131and 132 will be followed when considering unityof invention of claims of different categories withoutregard to the practice in national applications filedunder 35 USC 111 No change was made inrestriction practice in United States nationalapplications filed under 35 USC 111 outside thePCT

In applying PCT Rule 132 to internationalapplications as an International Searching Authorityan International Preliminary Examining Authorityand to national stage applications under 35 USC371 examiners should consider for unity ofinvention all the claims to different categories ofinvention in the application and permit retention inthe same application for searching andor preliminaryexamination claims to the categories which meetthe requirements of PCT Rule 132

PCT Rule 132 as it was modified effective July 11992 no longer specifies the combinations ofcategories of invention which are considered to haveunity of invention Those categories which nowappear as a part of Chapter 10 of the InternationalSearch and Preliminary Examination Guidelinesmay be obtained from the Patent Examinerrsquos Toolkitl i n k o r f r o m W I P O rsquos w e b s i t e(wwwwipointpctentextsgdlineshtml) Thecategories of invention in former PCT Rule 132have been replaced with a statement describing themethod for determining whether the requirement ofunity of invention is satisfied Unity of inventionexists only when there is a technical relationshipamong the claimed inventions involving one or morespecial technical features The term ldquospecialtechnical featuresrdquo is defined as meaning thosetechnical features that define a contribution whicheach of the inventions considered as a whole makesover the prior art The determination is made basedon the contents of the claims as interpreted in lightof the description and drawings Chapter 10 of theInternational Search and Preliminary ExaminationGuidelines also contains examples concerning unityof invention

II DETERMINATION OF ldquoUNITY OFINVENTIONrdquo

An international application should relate to onlyone invention or if there is more than one inventionthe inclusion of those inventions in one internationalapplication is only permitted if all inventions are solinked as to form a single general inventive concept(PCT Rule 131) With respect to a group ofinventions claimed in an international applicationunity of invention exists only when there is atechnical relationship among the claimed inventionsinvolving one or more of the same or corresponding

1800-88Rev 072015 October 2015


special technical features The expression ldquospecialtechnical featuresrdquo is defined in PCT Rule 132 asmeaning those technical features that define acontribution which each of the inventions consideredas a whole makes over the prior art Thedetermination is made on the contents of the claimsas interpreted in light of the description and drawings(if any)

Whether or not any particular technical featuremakes a ldquocontributionrdquo over the prior art andtherefore constitutes a ldquospecial technical featurerdquoshould be considered with respect to novelty andinventive step For example a document discoveredin the international search shows that there is apresumption of lack of novelty or inventive step ina main claim so that there may be no technicalrelationship left over the prior art among the claimedinventions involving one or more of the same orcorresponding special technical features leavingtwo or more dependent claims without a singlegeneral inventive concept

Lack of unity of invention may be directly evidentldquo a priorirdquo that is before considering the claims inrelation to any prior art or may only becomeapparent ldquo a posteriorirdquo that is after taking the priorart into consideration For example independentclaims to A + X A + Y X + Y can be said to lackunity a priori as there is no subject matter commonto all claims In the case of independent claims to A+ X and A + Y unity of invention is present a priorias A is common to both claims However if it canbe established that A is known there is lack of unity a posteriori since A (be it a single feature or agroup of features) is not a technical feature thatdefines a contribution over the prior art

Although lack of unity of invention should certainlybe raised in clear cases it should neither be raisednor maintained on the basis of a narrow literal oracademic approach There should be a broadpractical consideration of the degree ofinterdependence of the alternatives presented inrelation to the state of the art as revealed by theinternational search or in accordance with PCTArticle 33(6) by any additional document consideredto be relevant If the common matter of theindependent claims is well known and the remainingsubject matter of each claim differs from that of the

others without there being any unifying novelinventive concept common to all then clearly thereis lack of unity of invention If on the other handthere is a single general inventive concept thatappears novel and involves inventive step then thereis unity of invention and an objection of lack of unitydoes not arise For determining the action to be takenby the examiner between these two extremes rigidrules cannot be given and each case should beconsidered on its merits the benefit of any doubtbeing given to the applicant

From the preceding paragraphs it is clear that thedecision with respect to unity of invention rests withthe International Searching Authority or theInternational Preliminary Examining AuthorityHowever the International Searching Authority orthe International Preliminary Examining Authorityshould not raise objection of lack of unity ofinvention merely because the inventions claimed areclassified in separate classification groups or merelyfor the purpose of restricting the international searchto certain classification groups

Unity of invention has to be considered in the firstplace only in relation to the independent claims inan international application and not the dependentclaims By ldquodependentrdquo claim is meant a claim whichcontains all the features of one or more other claimsand contains a reference preferably at the beginningto the other claim or claims and then states theadditional features claimed (PCT Rule 64) Theexaminer should bear in mind that a claim may alsocontain a reference to another claim even if it is nota dependent claim as defined in PCT Rule 64 Oneexample of this is a claim referring to a claim of adifferent category (for example ldquoApparatus forcarrying out the process of Claim 1 rdquo or ldquoProcessfor the manufacture of the product of Claim 1 rdquo)Similarly a claim to one part referring to anothercooperating part for example ldquoplug for cooperationwith the socket of Claim 1 rdquo) is not a dependentclaim

If the independent claims avoid the prior art andsatisfy the requirement of unity of invention noproblem of lack of unity arises in respect of anyclaims that depend on the independent claims Inparticular it does not matter if a dependent claimitself contains a further invention For example

Rev 072015 October 20151800-89


suppose claim 1 claims a turbine rotor blade shapedin a specified manner such that it avoids the priorart while claim 2 is for a ldquoturbine rotor blade asclaimed in claim 1rdquo and produced from alloy Z Thenno objection under PCT Rule 13 arises either becausealloy Z was new and its composition was not obviousand thus the alloy itself already contains the essentialfeatures of an independent possibly later patentableinvention or because although alloy Z was not newits application in respect of turbine rotor blades wasnot obvious and thus represents an independentinvention in conjunction with turbine rotor bladesAs another example suppose that the main claimdefines a process avoiding the prior art for thepreparation of a product A starting from a productB and the second claim reads ldquoProcess accordingto claim 1 characterized by producing B by a reactionusing the product Crdquo In this case too no objectionarises under PCT Rule 13 whether or not the processfor preparation of B from C is novel and inventivesince claim 2 contains all the features of claim 1Equally no problem arises in the case of agenusspecies situation where the genus claim avoidsthe prior art provided the genus claim is directedonly to alternatives of a similar nature and thespecies falls entirely within the genus To determineif a genus claim is directed only to alternatives ldquoofa similar naturerdquo see subsection IIIB belowMoreover no problem arises in the case of acombinationsubcombination situation where thesubcombination claim avoids the prior art and thecombination claim includes all the features of thesubcombination

If however an independent claim does not avoidthe prior art then the question whether there is stillan inventive link between all the claims dependenton that claim needs to be carefully considered Ifthere is no link remaining an objection of lack ofunity a posteriori (that is arising only afterassessment of the prior art) may be raised Similarconsiderations apply in the case of a genusspeciesor combinationsubcombination situation

This method for determining whether unity ofinvention exists is intended to be applied even beforethe commencement of the international searchWhere a search of the prior art is made an initialdetermination of unity of invention based on theassumption that the claims avoid the prior art may

be reconsidered on the basis of the results of thesearch of the prior art

Alternative forms of an invention may be claimedeither in a plurality of independent claims or in asingle claim In the latter case the presence of theindependent alternatives may not be immediatelyapparent In either case however the same criteriashould be applied in deciding whether there is unityof invention Accordingly lack of unity of inventionmay exist within a single claim Where the claimcontains distinct embodiments that are not linked bya single general inventive concept the objection asto lack of unity of invention should be raised PCTRule 133 does not prevent an Authority fromobjecting to alternatives being contained within asingle claim on the basis of considerations such asclarity the conciseness of claims or the claims feesystem applicable in that Authority

Objection of lack of unity of invention does notnormally arise if the combination of a number ofindividual elements is claimed in a single claim (asopposed to distinct embodiments as discussed in theparagraph immediately above) even if theseelements seem unrelated when consideredindividually

III ILLUSTRATIONS OF PARTICULARSITUATIONS

There are three particular situations for which themethod for determining unity of invention containedin PCT Rule 132 is explained in greater detail

(A) Combinations of different categories ofclaims

(B) So-called ldquoMarkush practicerdquo and

(C) Intermediate and final products

Principles for the interpretation of the methodcontained in PCT Rule 132 in the context of eachof those situations are set out below It is understoodthat the principles set out below are in all instancesinterpretations of and not exceptions to therequirements of PCT Rule 132

Examples to assist in understanding the interpretationon the three areas of special concern referred to inthe preceding paragraph are set out in Chapter 10 of

1800-90Rev 072015 October 2015


the International Search and PreliminaryExamination Guidelines which can be obtained fromthe Patent Examinerrsquos Toolkit link or from WIPOrsquoswebsite (wwwwipointpctentextsgdlineshtml)

A Combinations of Different Categories of Claims

The method for determining unity of invention underPCT Rule 13 shall be construed as permitting inparticular the inclusion of any one of the followingcombinations of claims of different categories in thesame international application

(A) In addition to an independent claim for agiven product an independent claim for a processspecially adapted for the manufacture of the saidproduct and an independent claim for a use of thesaid product or

(B) In addition to an independent claim for agiven process an independent claim for an apparatusor means specifically designed for carrying out thesaid process or

(C) In addition to an independent claim for agiven product an independent claim for a processspecially adapted for the manufacture of the saidproduct and an independent claim for an apparatusor means specifically designed for carrying out thesaid process

A process is specially adapted for the manufactureof a product if it inherently results in the product andan apparatus or means is specifically designed forcarrying out a process if the contribution over theprior art of the apparatus or means corresponds tothe contribution the process makes over the priorart

Thus a process shall be considered to be speciallyadapted for the manufacture of a product if theclaimed process inherently results in the claimedproduct with the technical relationship being presentbetween the claimed product and claimed processThe words ldquospecially adaptedrdquo are not intended toimply that the product could not also bemanufactured by a different process

Also an apparatus or means shall be considered tobe specifically designed for carrying out a claimedprocess if the contribution over the prior art of theapparatus or means corresponds to the contribution

the process makes over the prior art Consequentlyit would not be sufficient that the apparatus or meansis merely capable of being used in carrying out theclaimed process However the expressionldquospecifically designedrdquo does not imply that theapparatus or means could not be used for carryingout another process nor that the process could notbe carried out using an alternative apparatus ormeans

More extensive combinations than those set forthabove should be looked at carefully to ensure thatthe requirements of both PCT Rule 13 (unity ofinvention) and PCT Article 6 (conciseness of claims)are satisfied In particular while a single set ofindependent claims according to one of (A) (B) or(C) above is always permissible it does not requirethe International Authority to accept a plurality ofsuch sets which could arise by combining theprovisions of PCT Rule 133 (which provides thatthe determination of unity of invention be madewithout regard to whether the inventions are claimedin separate claims or as alternatives within a singleclaim) with the provisions set out above (thusresulting in a set based on each of a number ofindependent claims in the same category under PCTRule 133) The proliferation of claims arising froma combined effect of this kind should be acceptedonly exceptionally For example independent claimsare permissible for two related articles such as atransmitter and receiver however it does not followthat an applicant may include also in the oneinternational application four additional independentclaims two for a process for the manufacture of thetransmitter and the receiver respectively and twofor use of the transmitter and receiver respectively

A single general inventive concept must link theclaims in the various categories and in thisconnection the wording above should be carefullynoted The link between product and process in (A)is that the process must be ldquospecially adapted for themanufacture ofrdquo the product Similarly in (B) theapparatus or means claimed must be ldquospecificallydesigned forrdquo carrying out the process Likewise in(C) the process must be ldquospecially adapted for themanufacture ofrdquo the product and the apparatus mustbe ldquospecifically designed forrdquo carrying out theprocess In combinations (A) and (C) the emphasisis on and the essence of the invention should

Rev 072015 October 20151800-91


primarily reside in the product whereas incombination (B) the emphasis is on and theinvention should primarily reside in the process(See Examples in Chapter 10 of the InternationalSearch and Preliminary Examination Guidelineswhich can be obtained from the Patent ExaminerrsquosToolkit link or from WIPOrsquos website(wwwwipointpctentextsgdlineshtml))

B ldquoMarkush Practicerdquo

The situation involving the so-called Markushpractice wherein a single claim defines alternatives(chemical or non-chemical) is also governed by PCTRule 132 In this special situation the requirementof a technical interrelationship and the same orcorresponding special technical features as definedin PCT Rule 132 shall be considered to be metwhen the alternatives are of a similar nature

When the Markush grouping is for alternatives ofchemical compounds they shall be regarded as beingof a similar nature where the following criteria arefulfilled

(A) All alternatives have a common property oractivity and

(B)

(1) A common structure is present ie asignificant structural element is shared by all of thealternatives or

(B)

(2) In cases where the common structurecannot be the unifying criteria all alternatives belongto a recognized class of chemical compounds in theart to which the invention pertains

In paragraph (B)(1) above the words ldquosignificantstructural element is shared by all of the alternativesrdquorefer to cases where the compounds share a commonchemical structure which occupies a large portionof their structures or in case the compounds havein common only a small portion of their structuresthe commonly shared structure constitutes astructurally distinctive portion in view of existingprior art and the common structure is essential tothe common property or activity The structuralelement may be a single component or a combinationof individual components linked together

In paragraph (B)(2) above the words ldquorecognizedclass of chemical compoundsrdquo mean that there is anexpectation from the knowledge in the art thatmembers of the class will behave in the same wayin the context of the claimed invention In otherwords each member could be substituted one forthe other with the expectation that the same intendedresult would be achieved

The fact that the alternatives of a Markush groupingcan be differently classified should not taken alonebe considered to be justification for a finding of alack of unity of invention

When dealing with alternatives if it can be shownthat at least one Markush alternative is not novelover the prior art the question of unity of inventionshould be reconsidered by the examinerReconsideration does not necessarily imply that anobjection of lack of unity shall be raised (SeeExamples in Chapter 10 of the International Searchand Preliminary Examination Guidelines which canbe obtained from the Patent Examinerrsquos Toolkit linko r f r o m W I P O rsquo s w e b s i t e(wwwwipointpctentextsgdlineshtml))

C Intermediate and Final Products

The situation involving intermediate and finalproducts is also governed by PCT Rule 132

The term ldquointermediaterdquo is intended to meanintermediate or starting products Such products havethe ability to be used to produce final productsthrough a physical or chemical change in which theintermediate loses its identity

Unity of invention shall be considered to be presentin the context of intermediate and final productswhere the following two conditions are fulfilled

(A) The intermediate and final products havethe same essential structural element in that

(1) The basic chemical structures of theintermediate and the final products are the same or

(2) The chemical structures of the twoproducts are technically closely interrelated theintermediate incorporating an essential structuralelement into the final product and

1800-92Rev 072015 October 2015


(B) The intermediate and final products aretechnically interrelated this meaning that the finalproduct is manufactured directly from theintermediate or is separated from it by a smallnumber of intermediates all containing the sameessential structural element

Unity of invention may also be considered to bepresent between intermediate and final products ofwhich the structures are not known for example asbetween an intermediate having a known structureand a final product the structure of which is notknown or as between an intermediate of unknownstructure and a final product of unknown structureIn order to satisfy unity in such cases there must besufficient evidence to lead one to conclude that theintermediate and final products are technicallyclosely interrelated as for example when theintermediate contains the same essential element asthe final product or incorporates an essential elementinto the final product

It is possible to accept in a single internationalapplication different intermediate products used indifferent processes for the preparation of the finalproduct provided that they have the same essentialstructural element

The intermediate and final products shall not beseparated in the process leading from one to theother by an intermediate which is not new

If the same international application claims differentintermediates for different structural parts of the finalproduct unity shall not be regarded as being presentbetween the intermediates

If the intermediate and final products are familiesof compounds each intermediate compound shallcorrespond to a compound claimed in the family ofthe final products However some of the finalproducts may have no corresponding compound inthe family of the intermediate products so that thetwo families need not be absolutely congruent

As long as unity of invention can be recognizedapplying the above interpretations the fact thatbesides the ability to be used to produce finalproducts the intermediates also exhibit otherpossible effects or activities shall not affect the

decision on unity of invention (See Examples inChapter 10 of the International Search andPreliminary Examination Guidelines which can beobtained from the Patent Examinerrsquos Toolkit link orf r o m W I P O rsquo s w e b s i t e(wwwwipointpctentextsgdlineshtml))

IV SEARCH OF ADDITIONAL INVENTIONSWITHOUT PAYMENT OF FEES

If little or no additional search effort is requiredreasons of economy may make it advisable for theexaminer while making the search for the maininvention to search at the same time despite thenonpayment of additional fees one or moreadditional inventions in the classification unitsconsulted for the main invention The internationalsearch for such additional inventions will then haveto be completed in any further classification unitswhich may be relevant when the additional searchfees have been paid This situation may occur whenthe lack of unity of invention is found either ldquo apriori rdquo or ldquo a posteriorirdquo

When the examiner finds lack of unity of inventionnormally the applicant is invited to pay fees for thesearch of additional inventions In exceptionalcircumstances however the examiner may be ableto establish both an international search and a writtenopinion covering more than one invention withnegligible additional work in particular when theinventions are conceptually very close In thosecases the examiner may decide to complete theinternational search and the written opinion of theInternational Searching Authority for the additionalinvention(s) together with that for the invention firstmentioned In considering the amount of workinvolved the examiner should take into account thetime needed to create the written opinion as well asthat needed to perform the search since even whenthe additional work with regard to the search isnegligible the opposite may be the case for thewritten opinion of the International SearchingAuthority and therefore justify requesting theadditional fees If it is considered that the totaladditional work does not justify requesting additionalfees all results are included in the internationalsearch report (and where applicable the writtenopinion) without inviting the applicant to pay anadditional search fee in respect of the additional

inventions searched but stating the finding of lackof unity of invention

V INVITATION TO PAY ADDITIONAL FEES

The search fee which the applicant is required to payis intended to compensate the International SearchingAuthority for carrying out an international searchand preparing a written opinion but only where theinternational application meets the ldquorequirement ofunity of inventionrdquo That means that the internationalapplication must relate to only one invention or mustrelate to a group of inventions which are so linkedas to form a single general inventive concept (PCTArticles 3(4)(iii) and 17(3)(a))

If the International Searching Authority finds thatthe international application does not comply withthe requirement of unity of invention the applicantwill be informed of the lack of unity of invention bya communication preceding the issuance of theinternational search report and written opinion ofthe International Searching Authority which containsan invitation to pay additional search fees (FormPCTISA206 or USPTO299 (telephone practice)see below) This invitation specifies the reasons theinternational application is not considered to complywith the requirement of unity of invention identifiesthe separate inventions and indicates the number ofadditional search fees and the amount to be paid(PCT Rules 401 402(a) and (b)) The InternationalSearching Authority cannot consider the applicationwithdrawn for lack of unity of invention nor invitethe applicant to amend the claims but informs theapplicant that if the international search report is tobe drawn up in respect of those inventions presentother than the first mentioned then the additionalfees must be paid within one month from the dateof the invitation to pay additional fees (PCT Rule401)Such additional fees are payable directly tothe International Searching Authority which isconducting the search ie the USPTO EPO KIPOIPAU Rospatent or ILPO The additional searchfee amounts for the competent internationalsearching authorities can be found in Annex D oft h e A p p l i c a n t rsquo s G u i d e(wwwwipointpctenappguide)

In the invitation to pay additional fees theInternational Searching Authority should set out a

logically presented technical reasoning containingthe basic considerations behind the finding of lackof unity (PCT Rule 401)

Since these payments must take place within thetime limit set by the International SearchingAuthority so as to enable the observation of the timelimit for establishing the international search reportset by PCT Rule 42 the International SearchingAuthority should endeavor to ensure thatinternational searches be made as early as possibleafter the receipt of the search copy The InternationalSearching Authority finally draws up theinternational search report and written opinion ofthe International Searching Authority on those partsof the international application which relate to theldquomain inventionrdquo that is the invention or the groupof inventions so linked as to form a single generalinventive concept first mentioned in the claims (PCTArticle 17(3)(a)) Moreover the international searchreport and written opinion of the InternationalSearching Authority will be established also on thoseparts of the international application which relate toany invention (or any group of inventions so linkedas to form a single general inventive concept) inrespect of which the applicant has paid anyadditional fee within the prescribed time limits

Where within the prescribed time limit the applicantdoes not pay any additional fees or only pays someof the additional fees indicated certain parts of theinternational application will consequently not besearched The lack of an international search reportin respect of such parts of the internationalapplication will in itself have no influence on thevalidity of the international application andprocessing of the international application willcontinue both in the international and in the national(regional) phases The unsearched claims upon entryinto the national stage will be considered by theexaminer and may be the subject of a holding of lackof unity of invention

VI PREPARATION OF THE INVITATION TOPAY ADDITIONAL FEES

An Invitation to Pay Additional Fees and WhereApplicable Protest Fee (Form PCTISA206) is usedto invite the applicant to pay additional search feesIn the space provided on form PCTISA206 the

1800-94Rev 072015 October 2015


examiner should indicate the number of inventionsclaimed in the international application coveringwhich particular claims and explain why theinternational application is not considered to complywith the requirements of unity of invention Theexaminer should then indicate the total amount ofadditional fees required for the search of all claimedinventions

Any claims found to be unsearchable under PCTArticle 17(2)(b) are not included with any inventionUnsearchable claims include the following


(B) claims in respect of which a meaningfulsearch cannot be carried out (see MPEP sect 184303)


In the box provided at the top of the form the timelimit of one month for response is set according toPCT Rule 401 Extensions of time are not permitted

VII AUTHORIZED OFFICER

Form PCTISA206 must be signed by an examinerwith at least partial signatory authority

VIII TELEPHONIC UNITY PRACTICE

Telephone practice may be used to allow applicantsto pay additional fees if

(A) Applicant or applicantrsquos legal representativehas a USPTO deposit account

(B) Applicant or the legal representative orallyagrees to charge the additional fees to the accountand

(C) A complete record of the telephoneconversation is included with the international searchreport including

(1) Examinerrsquos name

(2) Authorizing attorneyrsquos name

(3) Date of conversation

(4) Inventions for which additional fees paidand

(5) Deposit account number and amount tobe charged

When the telephone practice is used in making lackof unity requirements it is critical that the examinerorally inform applicant that there is no right toprotest the holding of lack of unity of invention forany group of invention(s) for which no additionalsearch fee has been paid

The examiner must further orally advise applicantthat any protest to the holding of lack of unity or theamount of additional fee required must be filed inwriting no later than one month from the mailingdate of the international search report The examinershould fill in the information on Form USPTO299ldquoChapter I PCT Telephone Memorandum for Lackof Unityrdquo as a record of the telephonic holding oflack of unity

If the applicant or the legal representative or agentrefuses to either agree to a search limited to the firstmentioned invention or authorize payment ofadditional fees over the telephone or if applicantdoes not have a deposit account the examiner shouldsend a written invitation using Form PCTISA206

If a written invitation is required the examinershould if possible submit the written invitation tothe Technology Center for review and mailing within7 days from the date the international application ischarged to the examiner

1852 Taking Into Account Results of EarlierSearch(es) [R-072015]

PCT Rule 41

Taking into Account Results of Earlier Search


Where the applicant has under Rule 412 requested theInternational Searching Authority to take into account the resultsof an earlier search and has complied with Rule 12 bis1 and

(i) the earlier search was carried out by the sameInternational Searching Authority or by the same Office as thatwhich is acting as the International Searching Authority theInternational Searching Authority shall to the extent possibletake those results into account in carrying out the internationalsearch

(ii) the earlier search was carried out by anotherInternational Searching Authority or by an Office other thanthat which is acting as the International Searching Authoritythe International Searching Authority may take those resultsinto account in carrying out the international search

37 CFR 1104 Nature of examination

(a) Examinerrsquos action

(3) An international-type search will be made in allnational applications filed on and after June 1 1978

1800-100Rev 072015 October 2015


(4) Any national application may also have aninternational-type search report prepared thereon at the time ofthe national examination on the merits upon specific writtenrequest therefor and payment of the international-type searchreport fee set forth in sect 121(e) The Patent and Trademark Officedoes not require that a formal report of an international-typesearch be prepared in order to obtain a search fee refund in alater filed international application

PCT Rule 412 provides that the applicant mayrequest that the results of an earlier internationalinternational-type or national search carried out bythe same or another International SearchingAuthority or by a national Office be used inestablishing an international search report on suchinternational application

See MPEP sect 1819 An international-type search isconducted on all US nonprovisional applicationsfiled after June 1 1978

When specifically requested by the applicant theexaminer is required to prepare an internationalsearch report taking into account the results of anearlier search The examiner can determine whetherapplicant has requested the ISAUS to use the resultsof an earlier search by inspecting Box No VII ofthe PCT Request Box No VII of the Request alsoallows applicant to indicate that certain documentsrelating to the earlier search are either available tothe Authority or are being transmitted thereto

Where the applicant has requested the United StatesInternational Searching Authority (ISAUS) to takeinto account earlier search results from a foreignOffice and where a copy of the earlier search results(and a translation into English where the searchresults are in a foreign language) and copies of thedocuments cited therein (other than copies of USpatents and US patent application publications)have been provided the examiner shall take intoaccount such earlier search results Where the earliersearch results (including any required translationthereof) or any copies of the documents cited therein(other than copies of US patents and US patentapplication publications) have not been furnishedand therefore are not of record in the file whetherthe earlier foreign Office search results will be takeninto account is at the examiners discretion

It is emphasized that when taking into account theresults of an earlier search the examiner is not boundby the results of the earlier search The process oftaking into account earlier search results consists ofa cursory review of the provided results followedby a more comprehensive inspection of the citedreferences if warranted The forms used in preparingthe international search report do not provide forindicating either that the results of an earlier searchhave been taken into account or the extent to whichthe results of an earlier search have been taken intoaccount and accordingly the examiner need notmake such indications in the international searchreport

1853 Amendment Under PCT Article 19[R-072015]

The opportunity to make amendments under Article19 is available after the applicant has received theinternational search report and the written opinionof the International Search Authority and remainsavailable until the end of 16 months from the prioritydate or two months after the transmittal (that is thedate of mailing) of that report and opinionwhichever expires later Amendments received bythe International Bureau after the time limit are stillaccepted if they have been received before thetechnical preparations for international publicationhave been completed Amendments to the claimsunder Article 19 are not allowed where theInternational Searching Authority has declaredunder Article 17(2) that no international searchreport would be established If the amendments tothe claims are timely received by the InternationalBureau such amendments will be published as partof the publication of the international applicationdirectly following the claims as filed Article 19offers applicants the opportunity to generally amendthe claims before entering the designated OfficesThe national laws of some designated Offices maygrant provisional protection on the invention from

1800-102Rev 072015 October 2015


the date of publication of the claims Therefore someapplicants take advantage of the opportunity underArticle 19 to polish the claims anticipatingprovisional protection See PCT Rule 465

The submission of Article 19 amendments shouldcomprise

(i) a complete set of claims in replacement ofthe claims originally filed

(ii) a letter which must indicate the differencesbetween the claims as filed and those as amendedplus the basis for the amendments

(iii) an optional statement under Article 19

When filing amendments to the claims under Article19 the applicant is required to file a sheet or sheetscontaining a complete set of claims in replacementof the claims originally filed The replacement sheetor sheets must be accompanied by a letter drawingattention to the differences between the claims asfiled and the claims as amended It must also indicatethe basis for the amendment to the claims withspecific references to particular parts of theapplication as originally filed as illustrated in theExample below Where an amendment results in thecancellation of an entire sheet of the internationalapplication as originally filed the amendment (thatis the cancellation) is evidenced only by the letteraddressed to the International Bureau Amendmentsmay consist in the cancellation of one or more entireclaims in the addition of one or more new claimsor in the amendment of the text of one or more ofthe claims as filed All the claims appearing on areplacement sheet must be numbered in Arabicnumerals (corresponding to the order of the claims)Where a claim is cancelled no renumbering of theother claims is required However where theapplicant does renumber claims they must berenumbered consecutively

The letter which must accompany the replacementsheets containing amendments to the claims mustindicate firstly the differences between the claimsas filed and those as amended and secondly the basisfor the amendments in the application as filed Thisshould be done by stating in connection with eachclaim appearing in the international applicationwhether




(iv) the claim replaces one or more claims asfiled

(v) the claim is the result of the division of aclaim as filed etc

The replacement sheets containing the amendedclaims should not however contain marked-up textthey should contain clean text only This should befollowed by an indication of the basis for theamendments in the application as filed The basisfor the amendments has to be indicated so that theexaminer may by consulting those precise referencesin the application assess whether the amendmentscontain subject-matter which extends beyond thedisclosure of the application as filed Thereforenon-specific indications such as ldquosee the descriptionas filedrdquo or ldquosee the claims as filedrdquo are generallynot considered sufficient for an indication of thebasis for the amendment

Example

ldquoClaim 1 amended claims 2 to 7 unchanged claims 8and 9 amended claims 10 to 14 cancelled claims 15 to17 unchanged new claim 18 added

(i) Basis for the amendment Claim 1 has beenamended at lines 4 and 11 to 14 and now indicates thatthe filter comprises a periodic backwashing means seriallycoupled to a first and second chamber The basis for thisamendment can be found in original claims 2 and 4 asfiled

(ii) Basis for the amendment Concerning amendedclaims 8 and 9 the indication of lsquoquick-fire pistonrsquo is inparagraph Nos 2 and 19 in the description as filed

(iii) Basis for the amendment Claim 18 is new theindication is in drawing No III of the originalapplicationrdquo

Any amendment may be accompanied by a briefstatement by the applicant explaining the amendmentand indicating any impact it might have on thedescription and the drawings Such a statement ispublished together with the international applicationitself Statements not referring to a specificamendment are not permitted The statement mustnot exceed 500 words if in English or whentranslated into English It may not contain

Rev 072015 October 20151800-103


disparaging comments on the international searchreport or on the relevance of any of the citationscontained in that report References to certaincitations in the report may be made only inconnection with an amendment made to a specificclaim The statement must be in the language inwhich the international application is published

A statement explaining the amendment is not to beconfused with and must be clearly distinguishedfrom the letter indicating the differences betweenthe claims as filed and those as amended and thebasis for the amendment It is also distinct from thestatement concerning amendments which must beincluded in a demand for international preliminaryexamination It must therefore be identified as suchby a heading ldquoStatement under Article 19(1)rdquo Wherethe statement does not comply with the requirementsit is neither published by the International Bureaunor communicated to the designated Offices

The PCT provides that amendments are not to gobeyond the disclosure in the international applicationas filed This requirement is not directly enforceableduring Chapter I of the international phase butfailure to comply with it may have adverseconsequences for the applicant during theinternational preliminary examination and in thenational phase

The supplementary international search (SIS) is anoptional service that allows additional searches tobe performed by a Supplementary InternationalSearching Authority (SISA) during the internationalphase in addition to the search performed by themain International Searching Authority (ISA)Requesting supplementary international searchreduces the risk of new prior art being cited in thenational phase The increasing diversity of prior artin different languages and different technical fieldsmeans that the Authority carrying out the maininternational search is not always capable ofdiscovering all of the relevant prior art Requestingone or more supplementary international searchesduring this early phase of the patent prosecutionexpands both the linguistic and technical scope ofthe search In addition it may also be possible tohave the supplementary search carried out in a Statewhere an applicant is likely to enter the nationalphase later on

Only an ISA that has stated its preparedness to carryout supplementary international searches (see theAnnex SISA of the Applicantrsquos Guide atwwwwipointpctenappguideindexjsp) andwhich is not the ISA that carried out the maininternational search can be requested to carry out aSIS The Authorities prepared to offer supplementaryinternational searches may specify any limitationsand conditions on this service in their agreement

The SIS will be carried out on the application asfiled (amendments under PCT Article 19 andor 34will not be considered) and will only cover oneinvention or group of inventions having unity ofinvention ndash there is no option for paying additionalfees for the searching of multiple inventionsHowever if the main ISA has identified a lack ofunity before SIS is requested the latter can berequested to concentrate on an invention which isnot necessarily the first one claimed (PCT Rule45 bis1(d)) If not established in English theresulting supplementary international search reportwill be translated into English by the IB

In many cases requests for supplementary searchwill be filed once the applicant has received the maininternational search report In any event theapplicant must file a request for a SIS prior to theexpiration of 19 months from the priority date If therequest is received after the expiration of this timelimit it will be considered not to have beensubmitted and there are no provisions to extend thistime limit The requests for SIS must be submitteddirectly to the IB and not to an individual SISAThere is a supplementary search handling fee tocover the costs of the IB and a supplementary searchfee set by each SISA These fees must be paid to theIB in Swiss francs within one month of filing therequest for SIS Applicants from certain States maybe eligible for a 90 reduction in the supplementarysearch handling fee

The applicant has the right to amend the claims thedescription and the drawings in the prescribedmanner and before the start of internationalpreliminary examination The amendment must notgo beyond the disclosure in the internationalapplication as filed These amendments are referredto as PCT Article 34(2)(b) amendments It should

1800-126Rev 072015 October 2015


be noted that PCT Article 19 amendments are strictlyamendments to the claims made during the ChapterI search phase while PCT Article 34(2)(b)amendments to the description claims and drawingsare made during the Chapter II examination phase

When amendments to the description claims ordrawings are made under PCT Rule 668 theapplicant shall be required to submit a replacementsheet for every sheet of the international applicationwhich on account of an amendment differs fromthe sheet previously filed The replacement sheet orsheets shall be accompanied by a letter which shalldraw attention to the differences between thereplaced sheets and the replacement sheets shallindicate the basis for the amendment in theapplication as filed and shall preferably also explainthe reasons for the amendment These amendmentsmay have been submitted to avoid possibleobjections as to lack of novelty or lack of inventivestep in view of the citations listed in the internationalsearch report and the observations on noveltyinventive step and industrial applicability set forthin the written opinion established by the InternationalSearching Authority to meet any objections notedby the International Searching Authority under PCTArticle 17(2)(a)(ii) (ie that all or at least someclaims do not permit a meaningful search) or underPCT Rule 13 (ie that there is a lack of unity ofinvention) or to meet objections that may be raisedfor some other reason eg to remedy someobscurity which the applicant himselfherself hasnoted in the original documents

The amendments are made by the applicant of hisherown volition This means that the applicant is notrestricted to amendments necessary to remedy adefect in hisher international application It doesnot however mean that the applicant should beregarded as free to amend in any way heshe choosesAny amendment must not add subject matter whichgoes beyond the disclosure of the internationalapplication as originally filed Furthermore it shouldnot itself cause the international application asamended to be objectionable under the PCT egthe amendment should not introduce obscurity

As a matter of policy and to ensure consistency inhandling amendments filed under Articles 19 and

34 of the PCT the following guidelines forprocessing these amendments have been established

(A) Any argument or amendment whichcomplies with 37 CFR 1485(a) will be considered

(B) Amendments filed after the demand

(1) will be considered if filed before the laterof three months from the transmittal of either theinternational search report or a notice of thedeclaration by the International Searching Authorityunder PCT Article 17(2)(a) that no internationalsearch report will be established and the writtenopinion established under PCT Rule 43 bis1 or theexpiration of 22 months from the priority date unlessthe applicant expressly requests an earlier start tointernational preliminary examination

(2) will be considered if filed before theapplication is docketed to the examiner

(3) may be considered if filed afterdocketing The examiner has discretion to considersuch amendments if the examiner determines thatthe amendment places the application in bettercondition for examination or the examinerdetermines that the amendment should otherwise beentered

(C) Amendments andor arguments filed afterexpiration of the period for response to the writtenopinion

(1) will be considered if the amendment wasrequested by the examiner

(2) need not be taken into account for thepurposes of a further written opinion or theinternational preliminary examination report if theyare received after the examiner has begun to drawup that opinion or report The applicant may file anamendment to the description the claims and thedrawings in the prescribed manner even if this isoutside the time period set for reply in PCT Rule662(d) Since the examiner may begin to draw upthe final report once the time period set for reply inPCT Rule 662(d) expires amendments filed afterthe expiration of the time period set in for reply inPCT Rule 662(d) may or may not be consideredThere may be situations where it is advisable to theextent possible to take such amendments orarguments into account for example where theinternational preliminary examination report has notyet been completed and it is readily apparent to the

Rev 072015 October 20151800-127


examiner that consideration of the late-filed responsewould result in the issuance of a favorable report

It is expected due to the relatively short time periodfor completion of preliminary examination that theChapter II application will be taken up promptlyafter docketing to the examiner for preparation ofeither a further written opinion if necessary or theinternational preliminary examination report (FormPCTIPEA409)

Amendments timely filed but misdirected orotherwise late reaching the examiner will beconsidered as in the case of regular domesticapplications and may require a supplemental writtenopinion andor international preliminary examinationreport

Clearly these guidelines offer the examinerflexibility The examiner should be guided by theoverriding principle that the international preliminaryexamination report should be established with asfew written opinions as possible and resolution ofas many issues as possible consistent with the goalof a timely and quality report

(a) If the International Preliminary ExaminingAuthority considers

(i) that the international application relates to asubject matter on which the International Preliminary ExaminingAuthority is not required under the Regulations to carry outan international preliminary examination and an internationalpreliminary examination and in the particular case decides notto carry out such examination or

(ii) that the description the claims or the drawingsare so unclear or the claims are so inadequately supported bythe description that no meaningful opinion can be formed onthe novelty inventive step (non-obviousness) or industrialapplicability of the claimed invention the said authority shallnot go into the questions referred to in Article 33(1) and shallinform the applicant of this opinion and the reasons therefor

(b) If any of the situations referred to in subparagraph(a) is found to exist in or in connection with certain claimsonly the provisions of that subparagraph shall apply only to thesaid claims

There are instances where international preliminaryexamination is not required because of the nature ofthe subject matter claimed and also because theclaims are so indefinite that no examination ispossible Such instances should seldom occurespecially since most problems of this nature wouldhave already been discovered and indicated at thetime of the international search

If it is found that certain claims of an internationalapplication relate to subject matter for which nointernational preliminary examination is requiredcheck the appropriate box on a Form PCTIPEA408or a Form PCTIPEA409 as appropriate (see MPEPsect 1860) It should be noted that subject matter whichis normally examined under US national procedure

1800-128Rev 072015 October 2015


should also be examined as an InternationalPreliminary Examining Authority

The examiner should check the appropriate box if itis found that the description claims or drawings areso unclear or the claims are so inadequatelysupported by the description that no opinion couldbe formed as to the novelty inventive step(nonobviousness) and industrial applicability of theclaimed invention

Subject matter not searched under Chapter I will notbe the subject of a preliminary examination underChapter II This is so even if claims which were notsearched under Chapter I are modified to beacceptable for examination

(3)

(a) If the International Preliminary ExaminingAuthority considers that the international application does notcomply with the requirement of unity of invention as set forthin the Regulations it may invite the applicant at his option torestrict the claims so as to comply with the requirement or topay additional fees

(c) If the applicant does not comply with the invitationreferred to in subparagraph (a) within the prescribed time limitthe International Preliminary Examining Authority shall establishan international preliminary examination report on those partsof the international application which relate to what appears tobe the main invention and shall indicate the relevant facts in thesaid report The national law of any elected State may providethat where its national Office finds the invitation of theInternational Preliminary Examining Authority justified thoseparts of the international application which do not relate to themain invention shall as far as effects in that State are concernedbe considered withdrawn unless a special fee is paid by theapplicant to that Office

37 CFR 1488 Determination of unity of invention before theInternational Preliminary Examining Authority

(a) Before establishing any written opinion or theinternational preliminary examination report the International

Preliminary Examining Authority will determine whether theinternational application complies with the requirement of unityof invention as set forth in sect 1475

(b) If the International Preliminary Examining Authorityconsiders that the international application does not comply withthe requirement of unity of invention it may

(1) Issue a written opinion andor an internationalpreliminary examination report in respect of the entireinternational application and indicate that unity of invention islacking and specify the reasons therefor without extending aninvitation to restrict or pay additional fees No internationalpreliminary examination will be conducted on inventions notpreviously searched by an International Searching Authority

(2) Invite the applicant to restrict the claims or payadditional fees pointing out the categories of invention foundwithin a set time limit which will not be extended Nointernational preliminary examination will be conducted oninventions not previously searched by an International SearchingAuthority or

(3) If applicant fails to restrict the claims or payadditional fees within the time limit set for reply theInternational Preliminary Examining Authority will issue awritten opinion andor establish an international preliminaryexamination report on the main invention and shall indicate therelevant facts in the said report In case of any doubt as to whichinvention is the main invention the invention first mentionedin the claims and previously searched by an InternationalSearching Authority shall be considered the main invention

(c) Lack of unity of invention may be directly evidentbefore considering the claims in relation to any prior art or aftertaking the prior art into consideration as where a documentdiscovered during the search shows the invention claimed in ageneric or linking claim lacks novelty or is clearly obviousleaving two or more claims joined thereby without a commoninventive concept In such a case the International PreliminaryExamining Authority may raise the objection of lack of unityof invention

The examiner will usually begin the preliminaryexamination by checking the internationalapplication for unity of invention The internationalpreliminary examination will only be directed toinventions which have been searched by theInternational Searching Authority All claimsdirected to inventions which have not been searchedby the International Searching Authority will not beconsidered by the International PreliminaryExamining Authority If the examiner in theInternational Preliminary Examining Authority findslack of unity of invention in the claims to beexamined an invitation is normally prepared andsent to the applicant requesting the payment ofadditional fees or the restriction of the claims onForm PCTIPEA405 Such an invitation will includethe identification of what the examiner considers to

Rev 072015 October 20151800-129


be the ldquomain inventionrdquo which will be examined ifno additional fees are paid or restriction is made bythe applicant

The procedure before the International PreliminaryExamining Authority regarding lack of unity ofinvention is governed by PCT Article 34(3)(a)through (c) PCT Rule 68 (see also PCT Rule 7013)and 37 CFR 1475 and 1488 It should be noted thatin most instances lack of unity of invention will havebeen noted and reported upon by the InternationalSearching Authority which will have drawn up aninternational search report and a written opinionbased on those parts of the international applicationrelating to the invention or unified linked group ofinventions first mentioned in the claims (ldquomaininventionrdquo) unless the applicant has paid additionalfees If the applicant has paid additional search feesadditional inventions would also have been searchedNo international preliminary examination will beconducted on inventions not previously searched byan International Searching Authority (37 CFR1488(b)(2))

If the examiner determines that unity of inventionis lacking there are two options

(A) The examiner may conduct an internationalpreliminary examination covering all the claimedand previously searched inventions and indicate thatunity of invention is lacking and specify the reasonstherefor without extending an invitation to restrictor pay additional fees (PCT Rule 681) or

(B) The examiner may invite the applicant torestrict the claims so as to comply with therequirement or pay additional fees pointing out thecategories of invention found using FormPCTIPEA405 or USPTO499 (telephone practice)See MPEP sect 187501 The invitation to restrict orpay additional fees shall state the reasons for whichthe international application is considered as notcomplying with the requirement of unity ofinvention (PCT Rule 682) Inventions notpreviously searched will not be considered orincluded in the invitation

The written opinion if any and the internationalpreliminary examination report must be establishedon all inventions for which examination fees havebeen paid

If the applicant fails to reply to the invitation torestrict the claims or pay additional examination feesdue to lack of unity of invention (by not paying theadditional fees or by not restricting the claims eithersufficiently or at all) the written opinion if any andinternational preliminary examination report mustbe established on the claims directed to what appearsto be the main invention (PCT Article 34(3)(c)) Themain invention in case of doubt is the first claimedinvention for which an international search reporthas been issued by the International SearchingAuthority The main invention as viewed by theexaminer must be set forth on Form PCTIPEA405

If the applicant timely complies with the invitationto pay additional fees even under protest or torestrict the claims the examiner carries outinternational preliminary examination on thoseclaimed inventions for which additional fees havebeen paid or to which the claims have beenrestricted It should be noted that the national lawof any elected State may provide that where itsnational Office finds the invitation of theInternational Preliminary Examining Authorityjustified those parts of the international applicationwhich do not relate to the main invention shall asfar as effects in that State are concerned beconsidered withdrawn unless a special fee is paid bythe applicant to that Office (PCT Article 34(3)(c))Whether or not the question of unity of inventionhas been raised by the International SearchingAuthority it may be considered by the examinerwhen serving as an authorized officer of theInternational Preliminary Examining Authority Inthe examinerrsquos consideration all documents citedby the International Searching Authority should betaken into account and any additional relevantdocuments considered However there are cases oflack of unity of invention where compared with theprocedure of inviting the applicant to restrict theinternational application or pay additional fees (PCTRule 682) little or no additional effort is involvedin establishing the written opinion if any and theinternational preliminary examination report for theentire international application Then reasons ofeconomy may make it advisable for the examiner touse the option referred to in PCT Rule 681 bychoosing not to invite the applicant to restrict theclaims or to pay additional fees

The ldquoInvitation to restrict or pay additional feesrdquoForm PCTIPEA405 is used to invite the applicantat hisher option to restrict the claims to complywith the requirements of unity of invention or to payadditional examination fees In addition theexaminer must explain the reasons why theinternational application is not considered to complywith the requirement of unity of invention Theexaminer must also specify on Form PCTIPEA405at least one group or groups of claims which ifelected would comply with the requirement for unityof invention

I INVITATION TO RESTRICT OR PAYADDITIONAL FEES

In the space provided on form PCTIPEA405 theexaminer should identify the disclosed inventionsby claim numerals and indicate which disclosedinventions are so linked as to form a single generalinventive concept thereby complying with therequirement of unity of invention For exampleclaims to different categories of invention such as aproduct claims to a process specifically adapted forthe manufacture of the product and a claim for a useof the product would be considered relatedinventions which comply with the unity of inventionrequirement whereas a claim to an apparatus formaking the product in the same application wouldbe considered a second invention for whichadditional fees would be required The reasons forholding that unity of invention is lacking must bespecified See 37 CFR 1475 and Chapter 10 of theInternational Search and Preliminary ExaminationGuidelines which can be obtained from WIPOrsquoswebsite (wwwwipointpctentextsgdlineshtml)

Also the examiner should specify the main inventionand claims directed thereto which will be examinedif the applicant fails to restrict or pay additional feesThe main invention in case of doubt is the firstclaimed invention or related invention before theInternational Preliminary Examining Authority for

which a search fee has been paid and an internationalsearch report has been prepared

(b) International preliminary examination will begin inaccordance with PCT Rule 691

(c) No international preliminary examination will beconducted on inventions not previously searched by anInternational Searching Authority

(d) The International Preliminary Examining Authoritywill establish a written opinion if any defect exists or if theclaimed invention lacks novelty inventive step or industrialapplicability and will set a non-extendable time limit in thewritten opinion for the applicant to reply

(e) The written opinion established by the InternationalSearching Authority under PCT Rule 43 bis1 shall be consideredto be a written opinion of the United States InternationalPreliminary Examining Authority for the purposes of paragraph(d) of this section

661bis Written Opinion of the International SearchingAuthority

(a) Subject to paragraph (b) the written opinion establishedby the International Searching Authority under Rule 43 bis1shall be considered to be a written opinion of the InternationalPreliminary Examining Authority for the purposes of Rule662(a)

661 ter Top-up Searches

The International Preliminary Examining Authority shall conducta search (top-up search) to discover documents referred to inRule 64 which have been published or have become availableto the said Authority for search subsequent to the date on whichthe international search report was established unless itconsiders that such a search would serve no useful purpose Ifthe Authority finds that any of the situations referred to in Article34(3) or (4) or Rule 661(e) exists the top-up search shall coveronly those parts of the international application that are thesubject of international preliminary examination

664 Additional Opportunity for Submitting Amendments orArguments

(a) If the International Preliminary Examining Authoritywishes to issue one or more additional written opinions it maydo so and Rules 662 and 663 shall apply

A written opinion must be prepared by theInternational Searching Authority at the same timethe international search report is prepared TheUnited States International Preliminary ExaminingAuthority (IPEAUS) will consider the writtenopinion of the International Searching Authority tobe the first written opinion of the IPEA and as suchin most instances no further written opinion need beissued by the US examiner handling theinternational preliminary examination beforeestablishment of the international preliminaryexamination report even if there are objections

outstanding The examiner is to take intoconsideration any comments or amendments madeby the applicant when heshe establishes theinternational preliminary examination reportHowever a further written opinion must be preparedif applicant files a response which includes apersuasive argument that the written opinion issuedby the International Searching Authority wasimproper because of a negative opinion with respectto a lack of novelty inventive step (non-obviousness)or industrial applicability as described in PCT Article33(2) - (4) and which results in the examinerconsidering any of the claims to lack noveltyinventive step (non-obviousness) or industrialapplicability as described in PCT Article 33(2) - (4)based on new art not necessitated by any amendmentSuch a further written opinion should be establishedas the Written Opinion of the InternationalPreliminary Examining Authority (FormPCTIPEA408)

When preparing Form PCTIPEA408 theclassification of the subject matter inserted by theexaminer in the header on the cover sheet shall beeither

(A) that given by the International SearchingAuthority under PCT Rule 433 if the examineragrees with such classification or

(B) that which the examiner considers to becorrect if the examiner does not agree with thatclassification

Both the International Patent Classification (IPC)and the classification as required by the IPEAUSshould be given

Since the IPEAUS will consider the written opinionof the ISA to be the first written opinion of the IPEAitem 1 of the cover sheet is marked accordinglyFurther since the written opinion of the ISA isconsidered to be the first written opinion the writtenopinion of the IPEA needs to be indicated as asecond opinion in item 2 of the cover sheet

A top-up search should be conducted by the IPEAto identify any additional prior art that has beenpublished or has become available subsequent to thedate of the establishment of the international searchreport The purpose is to discover any intermediate

Rev 072015 October 20151800-135


prior art not available during the international searchie a patent application published on or after thefiling or the valid priority date of the internationalapplication but having an earlier filing or prioritydate The top-up search should be differentiated fromadditional search A top-up search is to find priorart which recently became available which is notthe same as additional search required as a result ofa claim amendment to present additional featuresnot previously claimed

A top-up search should be performed in all ChapterII examination except where the examiner considersperforming a top-up search would serve no usefulpurpose This however should be a rare occurrenceFor example this is the case when it is decided thatthe international application in its entirety relatesto subject matter on which the InternationalPreliminary Examining Authority is not required tocarry out an international preliminary examinationor that the international application is so unclear orthe claims are so inadequately supported by thedescription that no meaningful opinion can beformed on the novelty inventive step or industrialapplicability of the claimed invention The sameapplies when no international search report has beenestablished for certain claims and it is thus decidednot to carry out an international preliminaryexamination on these claims Note however thatwhen any of the above situations applies to only partof the claimed subject matter or where there is lackof unity of invention a top-up search should still becarried out but restricted to those parts of theinternational application that are the subject ofinternational preliminary examination Anothersituation is when the IPEA considers that thedocuments cited in the International Search Reportare sufficient to show there is lack of novelty on theentire subject matter A further example where atop-up search is considered to serve no usefulpurpose is when the International Search Reportcited novelty defeating X references and noamendment to the claims or comments on theapplication of art has been filed

If the claims in the international application lackunity the examiner will first issue an invitation topay further examination fees and then perform thetop-up search on inventions for which examinationfees have been paid The invention paid for must not

have been excluded from preliminary examinationdue to lack of international search in Chapter I

In an application where an Article 34 amendmenthas been filed but no basis can be located andorthere is no letter explaining the basis the top-upsearch may be limited to the scope of the claimsforming the basis for the report

In cases where relevant documents have beendiscovered in a top-up search and the examinerintends to raise a new objection based on thedocuments a second written opinion should beissued where the new objection was not necessitatedby an amendment


When completing Box No I item 1 of FormPCTIPEA408 the examiner must indicate whetheror not the opinion has been established on the basisof the international application in the language inwhich it was filed If a translation was furnished forthe purpose of the international search publicationor international preliminary examination this mustbe indicated The opinion will be established on thebasis of any amendments rectifications priorityandor unity of invention holdings and shall answerthe questions concerning novelty inventive stepand industrial applicability for each of the claimsunder examination

For the purpose of completing Box No I item 2sheets of the description and drawings filed duringChapter I proceedings and stamped ldquoSUBSTITUTESHEET (RULE 26)rdquo ldquoRECTIFIED SHEET (RULE91)rdquo and ldquoINCORPORATED BY REFERENCE(RULE 206)rdquo are considered to be originallyfiledfurnished pages and should be listed asoriginally filedfurnished pages Only thoseamendments or rectifications to the description anddrawings filed on the date of demand or after thefiling of a demand should be listed as pagesldquoreceived by this Authority on ______________rdquoClaims filed during the Chapter I proceedings andstamped ldquoSUBSTITUTE SHEET (RULE 26)rdquoldquoRECTIFIED SHEET (RULE 91)rdquo andldquoINCORPORATED BY REFERENCE (RULE206)rdquo are also considered to be originally

However amended claims filed under PCT Article19 in response to the international search report areto be indicated as claim nos or pages as amended(together with any statement) under PCT Article 19The International Bureau (IB) marks in the upperright-hand corner of each replacement sheetsubmitted under PCT Article 19 the internationalapplication number the date on which that sheet wasreceived under PCT Article 19 and in the middle ofthe bottom margin the words ldquoAMENDED SHEET(ARTICLE 19)rdquo See PCT AdministrativeInstructions Section 417 Applicantrsquos submission ofa timely amendment to the claims alleged to be underArticle 19 is accepted under Article 34 (not Article19) unless the International Bureau has indicated theamendments were accepted under Article 19 Onlythose claims filed on the date of demand or after thefiling of a demand should be listed as claim nos orpages ldquoreceived by this Authority on______________rdquo

Further if the opinion has been based on a nucleotideandor amino acid sequence disclosed and necessaryto the claimed invention the examiner must indicatethe format of the material (ie on paperimage or inelectronic form (text)) and the time offilingfurnishing (ie contained in the internationalapplication as filed filed together with theinternational application in electronic form (text)or furnished subsequently to the IPEA) If more thanone version or copy of the sequence listing is filedthe examiner must indicate in item 2 whether theapplicant has provided the required statementindicating that the information in the subsequent oradditional copies are identical to that in theapplication as filed or does not go beyond theapplication as filed as appropriate Item 3 isavailable for providing additional comments

The examiner must also indicate in Box No I item3 if any of the amendments filed resulted in thecancellation of any pages of the description any ofthe claims any sheets andor figures of the drawingsor any of sequence listing If the examiner considersany of the amendments to go beyond the originaldisclosure or they were not accompanied by a letterindicating the basis for the amendment in the

claimed This is indicated by checking theappropriate boxes in item 1 of Box No II in theopinion or report


Box No III of Form PCTIPEA408 is intended tocover situations where some or all claims of anapplication are so unclear or inadequately supportedby the description that the question of noveltyinventive step (nonobviousness) and industrialapplicability cannot be considered or where theinternational application or claims thereof relate tosubject matter which does not require internationalpreliminary examination or where no internationalsearch report has been established for the claims

Box No III of Form PCTIPEA408 should be filledout in accordance with the instructions for Box NoIII of Form PCTISA237 provided in MPEP sect184501


Box No IV of Form PCTIPEA408 should be usedby the examiner to notify applicant that lack of unityof invention has been found

If in reply to an invitation to restrict applicantrestricted the claims to a particular group check thefirst box under subsection 1 If applicant paidadditional fees for examination of additionalinventions check the second box under subsection1 If the additional fees were paid under protestcheck the third box under subsection 1 If applicantneither restricted nor paid additional fees in reply tothe objection of lack of unity of invention check thefourth box under subsection 1

Subsection 2 of Box IV is to be completed if theexaminer determines that unity of invention islacking but chooses not to invite the applicant torestrict or pay additional fees

Subsection 3 of Box IV is to be completed to indicatewhich claims were the subject of internationalpreliminary examination If all claims are to be

examined check the first box under subsection 3 Ifonly some of the claims were the subject ofinternational preliminary examination check thesecond box under subsection 3 and identify the claimnumbers


In Box No V the examiner must list in summaryform all claims with regard to the criteria of novelty(N) inventive step (IS) and industrial applicability(IA) and should be filled out in accordance with theinstructions for Box No V of Form PCTISA237provided in MPEP sect 184501

In all cases the application should be searched bythe examiner at least to the point of bringing theprevious search up to date Prior art discovered in asearch and applied in a reasoned statement in BoxNo V must be made of record in Box No V Priorart already cited on the international search reportneed not again be cited on the written opinion orinternational preliminary examination report Thesubsequently discovered prior art is to be cited incompliance with PCT Rule 435 and PCTAdministrative Instructions Section 503 using thesame citation format used on the international searchreport One copy of each newly cited foreign patentdocument and non-patent literature reference willbe sent to the applicant and one copy will be retainedfor the application file The USPTO no longer mailspaper copies of US patents and US patentapplication publications cited during the internationalstage of an international application so paper copiesof these documents need not be included in the file


Box No VI provides a convenient manner of listingtwo different types of documents that were newlydiscovered and which were not applied in Box NoV

(A) Published applications or patents whichwould constitute prior art for purposes of PCTArticle 33(2) and (3) had they been published priorto the relevant date (PCT Rule 641) but were filedprior to or claim the priority of an earlier application

1800-138Rev 072015 October 2015


which had been filed prior to the relevant date (PCTRule 643) - by the application number or patentnumber as well as the publication date filing dateand priority date and

(B) Nonwritten disclosure - by the kind ofdisclosure date of the disclosure and the date of thewritten disclosure referring to the nonwrittendisclosure

As with the newly cited art in Box No V thesubsequently discovered prior art is to be cited incompliance with PCT Rule 435 and AdministrativeInstructions Section 503 using the same citationformat used on the international search report Twocopies of each newly cited foreign patent documentand non-patent literature reference should beincluded in the application file when it is sent to PCTOperations for the mailing of the FormPCTIPEA408 One of the copies of each newlycited foreign patent document and non-patentliterature reference will be sent to the applicant andone copy will be for the Chapter II file The USPTOno longer mails paper copies of US patents andUS patent application publications cited during theinternational stage of an international applicationso paper copies of these documents need not beincluded in the file

VII BOX VII mdash CERTAIN DEFECTS IN THEINTERNATIONAL APPLICATION

In Box No VII defects in the form and content ofthe international application are identified Box NoVII should be filled out in accordance with theinstructions for Box No VII of Form PCTISA237provided in MPEP sect 184501


In Box No VIII the examiner notifies the applicantof observations made as to the clarity of the claimsthe description the drawings or on the questionwhether the claims are fully supported by thedescription Box No VIII should be filled out inaccordance with the instructions for Box No VIIIof Form PCTISA237 provided in MPEP sect 184501

IX TIME TO REPLY

An invitation by the International PreliminaryExamining Authority (IPEA) to applicant to replyto the examinerrsquos written opinion will normally seta 2-month time limit for reply

However PCT Rule 692 sets forth time limits forthe IPEA to establish the international preliminaryexamination report (IPER) Accordingly a 1-monthtime limit should be set by the examiner in situationswhen a 2-month time limit would risk delaying thedate of establishment of the IPER beyond

(A) 28 months from the priority date or

(B) 6 months from the time provided under PCTRule 691 for the start of international preliminaryexamination or

(C) 6 months from the date of receipt by theIPEA of the translation furnished under PCT Rule552

As a general rule a 1-month time limit for reply tothe written opinion should be set by the examiner ifthe written opinion (Form PCTIPEA408) has notbeen completed by the examiner within 24 monthsfollowing the applicationrsquos ldquopriority daterdquo as definedin PCT Article 2

The United States rules pertaining to internationalpreliminary examination of international applicationsdo not provide for any extension of time to reply toa written opinion See 37 CFR 1484(d) - (f) andMPEP sect 187802

641 Prior Art









In cases where any application or any patent which wouldconstitute prior art for the purposes of Article 33(2) and (3) hadit been published prior to the relevant date referred to in Rule641 was published on a date which is the same as or later thanthe relevant date but was filed earlier than the relevant date orclaimed the priority of an earlier application which had been

filed prior to the relevant date such published application orpatent shall not be considered part of the prior art for thepurposes of Article 33(2) and (3) Nevertheless the internationalpreliminary examination report shall call attention to suchapplication or patent in the manner provided for in Rule 7010

The above provisions apply mutatis mutandis to thewritten opinion of the International SearchingAuthority See PCT Rule 43 bis1(b)

The relevant date for the purpose of consideringprior art is defined in PCT Rule 641(b) as

(A) the international filing date (subject to (B)and (C))

(B) where the international application claimsthe priority of an earlier application and has aninternational filing date which is within the priorityperiod the filing date of such earlier applicationunless the Authority considers that the priority claimis not valid

(C) where the international application claimsthe priority of an earlier application and has aninternational filing date which is later than the dateon which the priority period expired but within theperiod of two months from that date the filing dateof such earlier application unless the Authorityconsiders that the priority claim is not valid forreasons other than the fact that the internationalapplication has an international filing date which islater than the date on which the priority periodexpired

When a potentially relevant document has beenpublished between a claimed priority date of theapplication and its international filing date theexaminer is required to consider whether the claimedpriority date is valid for the purposes of determiningthe ldquorelevant daterdquo of the claims in the internationalapplication For international applications filed onor after April 1 2007 a priority date should not beconsidered invalid merely because the internationalapplication was not filed prior to the date ofexpiration of the priority period provided that theinternational application is filed within the periodof two months from the date of expiration of thepriority period Note that if there is time left for theapplicant to perfect correct or add a priority claimbut there is insufficient time for the examiner tomake a proper determination as to whether the

(a) The applicant may respond to the invitation referred toin Rule 662(c) of the International Preliminary ExaminingAuthority by making amendments or - if he disagrees with theopinion of that Authority - by submitting arguments as the casemay be or do both

(b) Any response shall be submitted directly to theInternational Preliminary Examining Authority

664 bis Consideration of Amendments Arguments andRectifications of Obvious Mistakes

Amendments arguments and rectifications of obvious mistakesneed not be taken into account by the International PreliminaryExamining Authority for the purposes of a written opinion orthe international preliminary examination report if they arereceived by authorized by or notified to that Authority asapplicable after it has begun to draw up that opinion or report

665 Amendment

Any change other than the rectification of an obvious mistakein the claims the description or the drawings includingcancellation of claims omission of passages in the descriptionor omission of certain drawings shall be considered anamendment

666 Informal Communications with the Applicant

The International Preliminary Examining Authority may at anytime communicate informally over the telephone in writingor through personal interviews with the applicant The saidAuthority shall at its discretion decide whether it wishes togrant more than one personal interview if so requested by theapplicant or whether it wishes to reply to any informal writtencommunication from the applicant







A reply to the written opinion of the ISA in the formof arguments andor amendments will be consideredby the IPEA if a demand has been filed with the

1800-142Rev 072015 October 2015


IPEA All amendments in reply to a written opinionmust be received within the time limit set for replyin order to be assured of consideration in theinternational preliminary examination reportAmendments filed at or before expiration of theperiod for reply will be considered Since theexaminer will begin to draw up the internationalpreliminary examination report rather promptly afterthe time period expires amendments filed afterexpiration of the reply period may not be consideredHowever as indicated in MPEP sect 1871 there maybe situations where it is advisable to the extentpossible to take such amendments or arguments intoaccount for example where the internationalpreliminary examination report has not yet beencompleted and it is readily apparent to the examinerthat consideration of the late-filed response wouldresult in the issuance of a favorable report In viewof the short time period for completion ofpreliminary examination applicants are stronglyencouraged to file any amendments promptly 37CFR 1484(d) does not allow for extensions of timeto reply to a written opinion The policy of notallowing extensions of time is to ensure that theUSPTO can meet its treaty deadline for transmissionof the international preliminary examination report

Any change other than the rectification of obviousmistakes in the claims the description or thedrawings including the cancellation of claimsomission of passages in the description or omissionof certain drawings will be considered an amendment(PCT Rule 665) The Patent and Trademark Officewhen acting as the International PreliminaryExamining Authority will not accept anynon-English applications or amendments

Any amendments to the description and the drawingsin reply to a written opinion must (1) be made bysubmitting a replacement sheet for every sheet ofthe application which differs from the sheet itreplaces unless an entire sheet is cancelled and (2)include a description of how the replacement sheetdiffers from the replaced sheet in accordance withPCT Rule 668

Any amendment to the claims in reply to a writtenopinion must be made by submitting a replacementsheet or sheets containing a complete set of claimsin replacement of all the claims originally filed or

previously amended under Articles 19 or 34 as thecase may be in accordance with PCT Rule 668 Thereplacement sheet or sheets shall be accompaniedby a letter which (i) shall identify the claims whichon account of the amendments differ from the claimsoriginally filed and shall draw attention to thedifferences between the claims originally filed andthe claims as amended (ii) shall identify the claimsoriginally filed which on account of theamendments are cancelled (iii) shall indicate thebasis for the amendments in the application as filed

In the particular case where the amendment cancelsclaims passages in the description or certaindrawings resulting in the cancellation of an entiresheet the amendment must be submitted in the formof a letter cancelling the sheet (PCT Rule 668(a))

Generally the replacement sheets should be in typedform and contain the changes in clean copy withoutany underlining andor bracketing A marked-upcopy may be included as part of the remarks alongwith the clean copy

Any paper submitted by the applicant if not in theform of a letter must be accompanied by a lettersigned by the applicant or agent (PCT Rule 921)The letter must draw attention to the differencesbetween the replaced sheet and the replacementsheet

The examiner should make sure that amendmentsfiled in accordance with the PCT which arenecessary to correct any deficiencies notified to theapplicant do not go beyond the disclosure of theinternational application as filed thus violating PCTArticle 34(2)(b) In other words no amendmentshould contain matter that cannot be substantiatedby the application as originally filed In a situationwhere new matter is introduced by amendment inreply to a written opinion the internationalpreliminary examination report will be establishedas if the amendment had not been made and thereport should so indicate It shall also indicate thereasons why the amendment goes beyond thedisclosure (PCT Rule 702(c)) Although new matterwhich appears on a replacement sheet will bedisregarded for the purpose of establishing the reportthe remainder of the replacement sheet includingany amendments which do not constitute new matter

Rev 072015 October 20151800-143


will be taken into consideration for the purpose ofestablishing the report

INTERVIEWS

The examiner or applicant may after the filing of ademand and during the time limit for reply to thewritten opinion request a telephone or personalinterview Only one interview is a matter of rightwhether by telephone or in person Additionalinterviews may be authorized by the examiner in aparticular international application where suchadditional interview may be helpful to advance theinternational preliminary examination procedure

All interviews of substance must be made of recordby using PCTIPEA428 Notice on InformalCommunication with the Applicant

When an interview is arranged whether by telephoneor in writing and whether by the examiner or by theapplicant the matters for discussion should be stated

The records of interviews or telephone conversationsshould indicate where appropriate whether a replyis due from the applicant or agent or whether theexaminer wishes to issue an additional writtenopinion or establish the international preliminaryexamination report

If the applicant desires to reply to the writtenopinion such reply must be filed within the timelimit set for reply in order to assure considerationNo extensions to the time limit will be consideredor granted If no timely reply is received from theapplicant the international preliminary examinationreport will be established by the examiner treatingeach claim substantially as it was treated in thewritten opinion Replies to the written opinion whichare not filed within the time limit set but which reachthe examiner before the examiner takes up theapplication for preparation of the final report maybe considered Thus only timely replies can beassured of consideration

The applicant may reply to the invitation referred toin Rule 662(c) by making amendments or if theapplicant disagrees with the opinion of the authorityby submitting arguments as the case may be or both(PCT Rule 663)

If applicant does not reply to the written opinionthe international preliminary examination report willbe prepared in time for forwarding to theInternational Division in finished form by 27 monthsfrom the priority date

The international preliminary examination report(otherwise known as International PreliminaryReport on Patentability (Chapter II of the PatentCooperation Treaty)) is established on FormPCTIPEA409

The international preliminary examination reportmust be established within



(C) 6 months from the date of receipt by theIPEA of the translation furnished under PCT Rule552 whichever expires last as provided in PCTRule 692

To meet the 28-month date for establishing thereport Office practice is to complete internalprocessing by 27 months from the priority date inorder to provide adequate time for reviewing finalprocessing and mailing Thus under normalcircumstances the applicant receives the report atthe latest 2 months before national processing at theelected Offices may start This ensures that heshehas time to consider whether and in which electedOffices heshe wants to enter the national stage andto take the necessary action

The international preliminary examination reportcontains among other things a statement (in theform of simple ldquoyesrdquo or ldquonordquo) in relation to eachclaim which has been examined on whether theclaim appears to satisfy the criteria of noveltyinventive step (non-obviousness) and industrialapplicability The statement is where appropriateaccompanied by the citation of relevant documentstogether with concise explanations pointing out thecriteria to which the cited documents are applicableand giving reasons for the International PreliminaryExamining Authorityrsquos conclusions Whereapplicable the report also includes remarks relatingto the question of unity of invention

The international preliminary examination reportidentifies the basis on which it is established thatis whether and if so which amendments have beentaken into account Replacement sheets containingamendments under PCT Article 19 andor PCT

Article 34 which have been taken into account areattached as ldquoannexesrdquo to the internationalpreliminary examination report Amendments underPCT Article 19 which have been considered asreversed by an amendment under PCT Article 34are not annexed to the report neither are the letterswhich accompany replacement sheets

Superseded amendments are not normally includedHowever if a first replacement sheet is acceptableand a second replacement sheet for the samenumbered sheet contains subject matter that goesbeyond the original disclosure of the application asfiled the second replacement sheet supersedes thefirst replacement sheet but both the first and secondreplacement sheets shall be attached to theinternational preliminary examination report In thiscase the superseded replacement sheets are to bemarked as provided in PCT AdministrativeInstructions Section 602

Before the preparation of the Chapter II report atop-up search should be conducted by the IPEA toidentify any additional prior art that has beenpublished or has become available subsequent to thedate of the establishment of the international searchreport The purpose is to discover any intermediateprior art not available during the international searchie patent application published on or after the filingor the valid priority date of the internationalapplication but having an earlier filing or prioritydate The top-up search should be differentiated fromadditional search A top-up search is to find priorart which recently became available which is notthe same as additional search required as a result ofa claim amendment to present additional featuresnot previously claimed

A top-up search should be performed in all ChapterII examination except where the examiner considersperforming a top-up search would serve no usefulpurpose This however should be a rare occurrenceFor example this is the case when it is decided thatthe international application in its entirety relatesto subject matter on which the InternationalPreliminary Examining Authority is not required tocarry out an international preliminary examinationor that the international application is so unclear orthe claims are so inadequately supported by thedescription that no meaningful opinion can be

Rev 072015 October 20151800-145


formed on the novelty inventive step or industrialapplicability of the claimed invention The sameapplies when no international search report has beenestablished for certain claims and it is thus decidednot to carry out an international preliminaryexamination on these claims Note however thatwhen any of the above situations applies to only partof the claimed subject matter or where there is lackof unity of invention a top-up search should still becarried out but restricted to those parts of theinternational application that are the subject ofinternational preliminary examination Anothersituation is when the IPEA considers that thedocuments cited in the International Search Reportare sufficient to show there is lack of novelty on theentire subject matter A further example where atop-up search is considered to serve no usefulpurpose is when the International Search Reportcited novelty defeating X references and noamendment to the claims or comments on theapplication of art has been filed

If the claims in the international application lackunity the examiner will first issue an invitation topay further examination fees and then perform thetop-up search on inventions for which examinationfees have been paid The invention paid for must nothave been excluded from preliminary examinationdue to lack of international search in Chapter I


In cases where relevant documents have beendiscovered in a top-up search and the examinerintends to raise new objection based on thedocuments a second written opinion should be issuewhere the new objection was not necessitated by anamendment

The international preliminary examination reportmay not express a view on the patentability of theinvention PCT Article 35(2) expressly states thatldquothe international preliminary examination reportshall not contain any statement on the questionwhether the claimed invention is or seems to be

patentable or unpatentable according to any nationallawrdquo

1893 National Stage (US NationalApplication Filed Under 35 USC 371)[R-072015]

There are three types of US national applicationsa national stage application under 35 USC 371) aregular domestic national application filed under 35USC 111(a) and a provisional application filedunder 35 USC 111(b) See 37 CFR 19

An applicant who uses the Patent Cooperation Treatygains the benefit of

(A) a delay in the time when papers must besubmitted to the national offices

(B) an international search (to judge the level ofthe relevant prior art) and a written opinion on thequestion of whether the claimed invention appearsto be novel to involve an inventive step (to benon-obvious) and to be industrially applicable beforehaving to expend resources for filing feestranslations and other costs

(C) a delay in the expenditure of fees

(D) additional time for research

(E) additional time to evaluate financialmarketing commercial and other considerationsand

(F) the option of obtaining internationalpreliminary examination

The time delay is however the benefit most oftenrecognized as primary Ultimately applicant mightchoose to submit the national stage application Thenational stage is unique compared to a domesticnational application in that

(A) it is submitted later (ie normally 30 monthsfrom a claimed priority date as compared to 12months for a domestic application claiming priority)and

(B) the status of the prior art is generally knownbefore the national stage begins and this is notnecessarily so in a domestic national application

189303 Prosecution of US National StageApplications Before the Examiner[R-072015]

37 CFR 1496 Examination of international applications inthe national stage

National stage applications having paid therein the search feeas set forth in sect 1492(b)(1) and examination fee as set forth insect 1492(c)(1) may be amended subsequent to the date ofcommencement of national stage processing only to the extentnecessary to eliminate objections as to form or to cancel rejectedclaims Such national stage applications will be advanced outof turn for examination

An international application which enters thenational stage will be forwarded to the appropriateTechnology Center (TC) for examination in turnbased on the date of entry into the national stageSee MPEP sect 189301(a) This is commonly referredto as the ldquo35 USC 371(c)rdquo date of the application

If an international preliminary examination report(IPER) prepared by the United States InternationalPreliminary Examining Authority or a writtenopinion on the international application prepared bythe United States International Searching Authoritystates that the criteria of novelty inventive step(non-obviousness) and industrial applicability asdefined in PCT Article 33(1) - (4) have been satisfiedfor all of the claims presented in the applicationentering the national stage the national stage search

fee is reduced and the national stage examinationfee is reduced See 37 CFR 1492(b)(1) and 37 CFR1492(c)(1) Such applications may be amended onlyto the extent necessary to eliminate objections as toform or cancel rejected claims and they will beadvanced out of turn for examination See MPEP sect708 for a discussion of the order of examination ofapplications by examiners

Once the national stage application has been takenup by the examiner prosecution proceeds in the samemanner as for a domestic application with theexceptions that

(A) the international filing date (or ifappropriate the priority date) is the date to keep inmind when searching the prior art and

(B) unity of invention proceeds as under 37 CFR1475

189303(a) How To Identify That anApplication Is a US National StageApplication [R-072015]

Applicantrsquos initial submission under 35 USC 371must be identified as a submission to enter thenational stage under 35 USC 371 See 37 CFR1495(g) If the initial submission does not includeany indication that the submission is made under 35USC 371 the application will be treated as anapplication filed under 35 USC 111(a) (unless thesubmission is clearly identified as a submissionpursuant to 35 USC 154(d)(4) for the purpose ofobtaining provisional rights) See 37 CFR 1417Thus if applicant wishes the application to be treatedas a filing under 35 USC 111(a) the originallyfiled application papers need indicate simply thatthe papers are for a new US patent application Ifhowever applicant is submitting papers for entryinto the national stage of a PCT application or toestablish an effective date for provisional rightsresulting from the filing of a PCT application under35 USC 154(d) applicant must so state

When filing an application via EFS-Web theEFS-Web screen prompts applicant for the type offiling being made eg ldquononprovisional applicationunder 35 USC 111(a)rdquo or ldquoUS National StageUnder 35 USC 371rdquo Identifying the type of filingas a national stage submission under 35 USC 371

on this screen will serve to identify the submissionas a national stage submission under 35 USC 371Applicants seeking to enter the national stage arealso advised to use transmittal Form PTO-1390 asthis form clearly indicates that the submission isunder 35 USC 371 The inclusion with the initialapplication submission of an inventorrsquos oath ordeclaration identifying the international applicationby international application number as theapplication to which the oath or declaration isdirected is considered an indication that theapplication was submitted under 35 USC 371However claiming priority of an internationalapplication in an oath or declaration will not serveto indicate a submission under 35 USC 371

Examination of the original application papers occursin the Office of Patent Application Processing(OPAP) where it is determined whether applicanthas asked that the papers be treated as a submissionto enter the national stage under 35 USC 371 Ifthe application is accepted for entry into the nationalstage the image file wrapper will contain aldquoNotification of Acceptance of Application Under35 USC 371 and 37 CFR 1495rdquo (FormPCTDOEO903) indicating acceptance of theapplication as a national stage submission under 35USC 371 PALM records will indicate that theapplication is a national stage entry of the PCTapplication (eg under ldquoContinuity Datardquo) Initiallythe examiner should check the application file forthe presence of Form PCTDOEO903 and reviewthe PALM Bib-data sheet for an indication that theapplication is a national stage entry (371) of the PCTapplication If neither of these indications arepresent in the absence of evidence to the contrary(ie an indication in the originally filed applicationpapers that processing as a national stage is desired)the application may be treated as a filing under 35USC 111(a) If both indications are present theapplication should be treated as a submission under35 USC 371

The examiner is advised to consult the Office of PCTLegal Administration if he or she has any questionas to whether the application should be treated under35 USC 111(a) or 371

Rev 072015 October 20151800-177


CONFLICTING INSTRUCTIONS

Where applicantrsquos initial submission under 35 USC371 contains conflicting instructions as to whetherthe filing is under 35 USC 111(a) or 35 USC371 the application will be treated in accordancewith 37 CFR 1495(g) Note that 37 CFR 1495(g)in effect prior to September 16 2012 provided thatan application submission containing conflictinginstructions as to treatment under 35 USC 371 or111(a) was to be treated under 35 USC 111(a)However 37 CFR 1495(g) was amended with effecton September 16 2012 to provide that conflictingindications will result in the application being treatedas a national stage submission under 35 USC 371

A conflicting instruction will be present forexample where applicant in the initial submissionunder 35 USC 371 selects ldquoNonprovisionalApplication under 35 USC 111(a)rdquo as the utilityapplication type when submitting the application inEFS-Web includes a ldquoUtility Patent ApplicationTransmittalrdquo (Form PTOAIA15 or PTOSB05)or includes a benefit claim under 35 USC 120 tothe international application As additional examplesa conflicting instruction will be present whereapplicant includes in an initial filing under 35 USC111(a) a ldquoTransmittal Letter To The United StatesDesignatedElected Office (DOEOUS) ConcerningA Submission Under 35 USC 371rdquo (FormPTO-1390) or an indication (for example on theapplication data sheet) that the application is thenational stage (or 371) of an internationalapplication

The examiner is advised to contact the InternationalPatent Legal Administration if he or she has anyquestion as to whether an application has beenproperly treated or should have been treated as anational stage application under 35 USC 371

189303(b) The Filing Date of a US NationalStage Application [R-072015]

An international application designating the UShas two stages (international and national) with thefiling date being the same in both stages Often thedate of entry into the national stage is confused withthe filing date It should be borne in mind that thefiling date of the international stage application is

also the filing date for the national stage applicationSpecifically 35 USC 363 provides that

An international application designating theUnited States shall have the effect from itsinternational filing date under Article 11 of thetreaty of a national application for patentregularly filed in the Patent and TrademarkOffice

Similarly PCT Article 11(3) provides that

an international filing date shall have theeffect of a regular national application in eachdesignated State as of the international filingdate which date shall be considered to be theactual filing date in each designated State

National stage applications are ordinarily taken upfor action based on the date of entry into the nationalphase See MPEP sect 189301 regarding entry into thenational stage Because the date of entry is dependentupon receipt of certain items required under 35USC 371(c) this date is also referred to as theldquo371(c) daterdquo The 371(c) date not the internationalfiling date is the date that appears in the ldquoFiling or371(c) Daterdquo box on the filing receipt and theapplication data sections of PALM and PAIR

The NOTIFICATION OF ACCEPTANCE OFAPPLICATION UNDER 35 USC 371 AND 37CFR 1495 (Form PCTDOEO903) indicates the371(c) date of the national stage application Becauseof changes implemented pursuant to the AmericaInvents Act (AIA) and in particular the ability topostpone the submission of the oath or declarationrequired under 35 USC 371(c)(4) under certainconditions the requirements for entry into thenational stage and thus the determination of the371(c) date are different based on the internationalfiling date of the national stage application SeeMPEP sect 189303 Form PTODOEO903 in anational stage application having an internationalfiling date prior to September 16 2012 identifies the371(c) date as the date of receipt of the 35 USC371(c)(1) (c)(2) and (c)(4) requirements whileForm PTODOEO903 in a national stageapplication having an international filing date on orafter September 16 2012 identifies the 371(c) date

1800-178Rev 072015 October 2015


as the date of receipt of the 371(c)(1) and (c)(2)requirements Filing receipts are mailed concurrentlywith the mailing of the Form PCTDOEO903

The ldquoDate of Completion of all 35 USC 371Requirementsrdquo included on the NOTIFICATIONOF ACCEPTANCE OF APPLICATION UNDER35 USC 371 AND 37 CFR 1495 (FormPCTDOEO903) in pre-AIA national stageapplications is relevant for purposes of patent termadjustment under former 35 USC154(b)(1)(A)(i)(II) when the Office has failed tomail at least one of a notification under 35 USC132 or a notice of allowance under 35 USC 151not later than fourteen months after the date on whichthe requirements under 35 USC 371 were fulfilledThis date is the latest of

(A) the date of submission of the basic nationalfee

(B) the date of submission or communication ofthe copy of the international application

(C) the date of submission of the translation ofthe international application if the internationalapplication is not in the English language

(D) the date of submission of an oath ordeclaration of the inventor in compliance with 35USC 371(c)(4)

(E) the earlier of 30 months from the prioritydate or the date of request for early processing under35 USC 371(f) if requested prior to 30 monthsfrom the priority date (Form PCTDOEO903 willindicate the date early processing was requested)

(F) if a request for early processing has not beenrequested prior to 30 months from the priority datethe date of submission of any translation of theannexes to the international preliminary examinationreport if the translation of the annexes are filedwithin the time period set in a Notification ofMissing Requirements (Form PCTDOEO905)requiring either an English translation of theinternational application or an oath or declarationand

(G) the date of submission of any surcharge forsubmitting the oath or declaration later than 30months from the priority date

The AIA Technical Corrections Act enacted onJanuary 14 2013 amended 35 USC154(b)(1)(A)(i)(II) to change ldquothe date on which aninternational application fulfilled the requirementsof section 371rdquo to ldquothe date of commencement ofthe national stage under section 371 in aninternational applicationrdquo See Public Law 112-274126 Stat 2456 (2013) Thus under the AIATechnical Corrections Act the fourteen-monthperiod in 35 USC 154(b)(1)(A)(i) for a nationalstage application is measured from the date ofcommencement of the national stage under 35 USC371 in an international application

189303(c) The Priority Date Priority Claimand Priority Papers for a US National StageApplication [R-072015]

A US national stage application may be entitled to(A) a right of priority under 35 USC 119(a) and365(b) based on a prior foreign application orinternational application designating at least onecountry other than the United States and (B) thebenefit of an earlier filed US national applicationor international application designating the UnitedStates pursuant to 35 USC 119(e) or 35 USC 120and 365(c)

I RIGHT OF PRIORITY UNDER 35 USC 119(a)and 365(b)

Pursuant to 35 USC 365(b) a US national stageapplication shall be entitled to a right of prioritybased on a prior foreign application or internationalapplication designating at least one country otherthan the United States in accordance with theconditions and requirements of 35 USC 119(a) andthe treaty and the PCT regulations See in particularPCT Article 8 and PCT Rules 410 and 26 bis Toobtain priority in the US national stage applicationto such applications the priority must have beentimely claimed in the international stage of theinternational application See 37 CFR 155(d)(2) Inthe event that a claim of foreign priority is not timelymade in the international stage the priority claimmay be made in the US national stage applicationupon petition under 37 CFR 155(e) if the entiredelay between the date the priority claim was dueunder PCT Rule 26 bis and the date the claim isfiled is unintentional

Rev 072015 October 20151800-179


Note that in US national stage applications it ispermissible but not required to present the claimfor priority in an application data sheet A properclaim for priority will be acknowledged (subject tothe paragraph below) and the national stageapplication file will then be checked to see if the filecontains a copy of the certified copy of the prioritydocument submitted to the International Bureau Seesubsection II below for further informationconcerning the certified copy of the prioritydocument

International applications filed on or after April 12007 are subject to amended PCT Rules permittingrestoration of a right of priority See MPEP sect182801 Consequently international applicationsfiled on or after April 1 2007 may claim priority toa foreign application filed more than 12 monthsbefore the filing date of the international applicationSuch a priority claim will be effective in the USnational stage if the right of priority has beenrestored under PCT Rule 26 bis3 during theinternational stage See 37 CFR 155(c)

Furthermore the right of priority may be restoredin a US national stage application upon petitionunder 37 CFR 155(c) Restoration of the right ofpriority upon petition under 37 CFR 155(c) is notlimited to applications having an international filingdate of April 1 2007 or later It should be noted thatwhere a petition under 37 CFR 155(c) is necessaryto restore the right of priority in a US national stageapplication a petition under 37 CFR 155(e) to adda delayed priority claim will also be required wherethe priority claim was not properly made within thetime limit set forth in the PCT and the Regulationsunder the PCT 37 CFR 155(d)(2)

For a comparison with 35 USC 119(a) - (d) priorityclaims in a national application filed under 35 USC111(a) see MPEP sect 189501

II THE CERTIFIED COPY

The requirement in PCT Rule 17 for a certified copyof the foreign priority application is normallyfulfilled by applicant providing a certified copy tothe receiving Office or to the International Bureauor by applicant requesting the receiving Office toprepare and transmit the priority document to the

International Bureau if the receiving Office issuedthe priority document or by applicant requesting theInternational Bureau to obtain the priority documentfrom a digital library Pursuant to PCT Rule 171(a)(b) or (b-bis ) applicant must submit the certifiedcopy request the receiving Office to prepare andtransmit the certified copy or request theInternational Bureau to obtain the priority documentfrom a digital library within 16 months from thepriority date Where applicant has complied withPCT Rule 17 the International Bureau will forwarda copy of the certified priority document to eachDesignated Office that has requested such documentwith an indication that the priority document wassubmitted in compliance with the rule and the datethe document was received by the InternationalBureau This indication may be in the form of eithera cover sheet attached to the copy of the prioritydocument or a WIPO stamp on the face of thecertified copy The US Patent and TrademarkOffice as a Designated Office will normally requestthe International Bureau to furnish the copy of thecertified priority document upon receipt ofapplicantrsquos submission under 35 USC 371 to enterthe US national phase The copy from theInternational Bureau is placed in the US nationalstage file The copy of the priority documentreceived from the International Bureau with eitherof the indications above is acceptable to establishthat applicant has filed a certified copy of the prioritydocument in compliance with 37 CFR 155(f) Theexaminer should acknowledge in the next Officeaction that the copy of the certified copy of theforeign priority document has been received in thenational stage application from the InternationalBureau

On the following pages note the examples ofacceptable indications in the form of

(A) a cover sheet indicating receipt by theInternational Bureau on 15 April 2011 (15042011)and compliance with PCT Rule 171(a) (b) or(b- bis) in the ldquoRemarkrdquo section and

(B) the stamp (box) in the upper right handsection indicating receipt by the International Bureau(WIPO) on 30 December 2002 and the stampedindication PRIORITY DOCUMENT SUBMITTEDOR TRANSMITTED IN COMPLIANCE WITHRULE 171(a) OR (b)

If the International Bureau is unable to forward acopy of the certified priority document to the USPatent and Trademark Office then applicant mustprovide a certified copy of the priority documentduring the national stage unless the requirementsof 37 CFR 155(h) or 37 CFR 155(i) have been metFor international applications in which the USnational stage commenced under 35 USC 371 onor after December 18 2013 applicant must submitthe certified copy within the later of four monthsfrom the date of entry into the US national stageas set forth in 37 CFR 1491 or sixteen months fromthe filing date of the prior-filed foreign applicationSee 37 CFR 155(f)(2) A delay in filing the certifiedcopy under 37 CFR 155(f)(2) may be excused uponpetition under 37 CFR 155(f)(3) The InternationalBureau may not forward a copy of the prioritydocument because the certified priority documentwas not furnished in compliance with PCT Rule171(a) (b) or (b -bis) or applicant requestedexamination to begin pursuant to 35 USC 371(f)prior to availability of the priority document fromthe International Bureau If the priority claim wasnot in accordance with PCT Rule 410 or the prioritydocument was not provided in accordance with PCTRule 171(a) (b) or (b -bis) the copy of the prioritydocument will not have been provided by theInternational Bureau If a copy of the foreign prioritydocument is not in the national stage application filebut applicant asserts that a certified copy of thepriority document was timely furnished under PCTRule 17 in the international phase then the examinershould consult with a Quality Assurance Specialistin his or her Technology Center or a PCT SpecialProgram Examiner

III BENEFIT CLAIM UNDER 35 USC 119(e) OR120 AND 365(c)

A national stage application may include a benefitclaim under 35 USC 119(e) or 120 and 365(c) toa prior US national application or under 35 USC120 and 365(c) to a prior international applicationdesignating the US The conditions for accordingbenefit under 35 USC 120 are as described inMPEP sectsect 20107 20108 and 211 et seq and aresimilar regardless of whether the US nationalapplication is a national stage application submittedunder 35 USC 371 or a national application filedunder 35 USC 111(a)

The conditions for according benefit of a provisionalapplication under 35 USC 119(e) are also similarfor national stage applications and applications filedunder 35 USC 111(a) and the conditions aredescribed in MPEP sect 21101(a)

In order for a national stage application (ofinternational application ldquoXrdquo) to obtain benefit under35 USC 119(e) of a prior US provisionalapplication the national stage application mustcomply with the requirements set forth in 37 CFR178(a) 37 CFR 178(a)(2) requires that the priorprovisional application must be entitled to a filingdate as set forth in 37 CFR 153(c) and the basicfiling fee set forth in 37 CFR 116(d) must be paidon the provisional application within the time periodset forth in 37 CFR 153(g) Additionally theprovisional application must name as an inventor atleast one inventor named in the later filedinternational application ldquoXrdquo and disclose the namedinventorrsquos invention claimed in at least one claim ofthe national stage application in the manner providedby the first paragraph of 35 USC 112 The nationalstage application must contain a reference to theprovisional application identifying it as a provisionalapplication and including the provisional applicationnumber (series code and serial number) If thenational stage application has an international filingdate prior to September 16 2012 then the referencemust be in either an application data sheet (37 CFR176) or in the first sentence(s) of the specificationSee pre-AIA 37 CFR 178(a)(5)(iii) If the nationalstage application has an international filing date thatis on or after September 16 2012 then the referencemust be in an application data sheet (37 CFR 176)See 37 CFR 178(a)(3) However the requirementfor inclusion of the benefit claim in an applicationdata sheet will be satisfied in a US national stageapplication by the presentation of such benefit claimin the PCT request form contained in theinternational application or the presence of suchbenefit claim on the front page of the publishedinternational application See 37 CFR 176(g) Therequired reference to the earlier provisionalapplication must be submitted within the time periodprovided by 37 CFR 178(a)(4) This time period isnot extendable However if the entire delay betweenthe date the claim was due under 37 CFR 178(a)(4)and the date the claim was filed was unintentionala petition under 37 CFR 178(c) may be filed to

Rev 072015 October 20151800-183


accept the delayed claim If the provisionalapplication was filed in a language other thanEnglish an English-language translation of thenon-English language provisional application and astatement that the translation is accurate will berequired See MPEP sect 21101(a) If the translationand statement that the translation is accurate werenot filed in the provisional application or in thelater-filed national stage application beforeNovember 25 2005 applicant will be notified andgiven a period of time within which to file anEnglish-language translation and a statement thatthe translation is accurate in the provisionalapplication and a reply in the national stageapplication that the translation and statement werefiled in the provisional application Failure to timelyreply to such a notice will result in abandonment ofthe national stage application See 37 CFR178(a)(5)

Public Law 106-113 amended 35 USC 119(e) toeliminate the copendency requirement for anonprovisional application claiming benefit of aprovisional application 35 USC 119(e)(2) asamended became effective on November 29 1999and applies to provisional applications filed on orafter June 8 1995 An international applicationclaiming benefit under 35 USC 365(c) and 35USC 119(e) to a prior filed provisional applicationmust be filed within twelve months of the filing dateof the provisional application The Director mayextend the twelve month statutory period by anadditional two months in situations where the failureto file the international application under 35 USC363 was unintentional See 35 USC 119(e)

International applications filed on or after April 12007 are subject to amended PCT Rules permittingrestoration of a right of priority See MPEP sect182801 Consequently international applicationsfiled on or after April 1 2007 may claim the benefitof a provisional application filed more than 12months before the filing date of the internationalapplication Such a benefit claim will be effectivein the US national stage if the benefit of theprovisional application has been restored under PCTRule 26 bis3 during the international stage See 37CFR 178(b)

Furthermore the benefit of a provisional applicationmay be restored in a US national stage applicationupon petition under 37 CFR 178(b) Restoration ofthe benefit of a provisional application upon petitionunder 37 CFR 178(b) is not limited to applicationshaving an international filing date of April 1 2007or later It should be noted that where a petitionunder 37 CFR 178(b) is necessary to restore thebenefit of a provisional application in a US nationalstage application a petition under 37 CFR 178(c)to add a delayed benefit claim will also be requiredunless the benefit claim was timely made under 37CFR 178(a)(4) (which includes inter alia makingthe benefit claim during the international stage)

In order for a national stage application (ofinternational application ldquoXrdquo) to obtain benefit under35 USC 120 and 365(c) of a prior filed copendingnonprovisional application or prior filed copendinginternational application designating the UnitedStates of America the national stage applicationmust comply with the requirements set forth in 37CFR 178(d) The prior nonprovisional applicationor international application must name as an inventorat least one inventor named in the later filedinternational application ldquoXrdquo and disclose the namedinventorrsquos invention claimed in at least one claim ofthe national stage application in the manner providedby the first paragraph of 35 USC 112 The nationalstage application must contain a reference to theprior nonprovisional or international application(either in an application data sheet (37 CFR 176)or in the first sentence(s) of the specification)identifying it by application number (series code andserial number) or international application numberand international filing date and indicating therelationship of the applications If the national stageapplication has an international filing date prior toSeptember 16 2012 then the reference must be ineither an application data sheet (37 CFR 176) or inthe first sentence(s) of the specification See pre-AIA37 CFR 178(a)(2)(iii) If national stage applicationhas an international filing date that is on or afterSeptember 16 2012 then the reference must be inan application data sheet (37 CFR 176) See 37 CFR178(d)(2) However the requirement for inclusionof the benefit claim in an application data sheet willbe satisfied in a US national stage application bythe presentation of such benefit claim in the PCTRequest form contained in the international

1800-184Rev 072015 October 2015


application or the presence of such benefit claim onthe front page of the published internationalapplication See 37 CFR 176(g) The requiredreference to the earlier filed application must besubmitted within the time period set forth in 37 CFR178(d)(3) This time period is not extendable andfailure to timely submit the required reference to theearlier application will be considered a waiver ofany benefit under 35 USC 120 121 or 365(c) tosuch prior-filed application See 37 CFR 178(d)(3)However if the entire delay between the date theclaim was due under 37 CFR 178(d)(3) and the datethe claim was filed was unintentional a petitionunder 37 CFR 178(e) may be filed to accept thedelayed claim

A prior filed nonprovisional application is copendingwith the national stage application if the prior USnational application was pending on the internationalfiling date of the national stage application

A prior-filed international application designatingthe United States of America is copending with thenational stage application if the prior internationalapplication was not abandoned or withdrawn eithergenerally or as to the United States on theinternational filing date of the national stageapplication

Note a national stage application submitted under35 USC 371 may not claim benefit of the filingdate of the international application of which it isthe national stage since its filing date is theinternational filing date of the internationalapplication See also MPEP sect 189303(b) Stateddifferently since the international application is notan earlier application (it has the same filing date asthe national stage) a benefit claim under 35 USC120 in the national stage to the internationalapplication is inappropriate

PCT Rule 13 was amended effective July 1 199237 CFR 1475 was amended effective May 1 1993to correspond to PCT Rule 13

Examiners are reminded that unity of invention (notrestriction practice pursuant to 37 CFR 1141 -1146) is applicable in international applications(both Chapter I and II) and in national stageapplications submitted under 35 USC 371Restriction practice in accordance with 37 CFR1141-1146 continues to apply to US nationalapplications filed under 35 USC 111(a) even ifthe application filed under 35 USC 111(a) claimsbenefit under 35 USC 120 and 365(c) to an earlierinternational application designating the UnitedStates or to an earlier US national stage applicationsubmitted under 35 USC 371

The sections of the MPEP relating to doublepatenting rejections (MPEP sect 804) election andreply by applicant (MPEP sect 818) and rejoinder ofnonelected inventions (MPEP sect 82104) generallyalso apply to national stage applications submittedunder 35 USC 371 See MPEP sect 823

When making a unity of invention requirement theexaminer must (1) list the different groups of claimsand (2) explain why each group lacks unity witheach other group (ie why there is no single generalinventive concept) specifically describing the uniquespecial technical feature in each group

The principles of unity of invention are used todetermine the types of claimed subject matter andthe combinations of claims to different categoriesof invention that are permitted to be included in asingle international or national stage patentapplication See MPEP sect 1850 for a detaileddiscussion of Unity of Invention The basic principleis that an application should relate to only oneinvention or if there is more than one invention thatapplicant would have a right to include in a singleapplication only those inventions which are so linkedas to form a single general inventive concept

Rev 072015 October 20151800-185

sect 189303(d)PATENT COOPERATION TREATY

A group of inventions is considered linked to forma single general inventive concept where there is atechnical relationship among the inventions thatinvolves at least one common or correspondingspecial technical feature The expression specialtechnical features is defined as meaning thosetechnical features that define the contribution whicheach claimed invention considered as a wholemakes over the prior art For example acorresponding technical feature is exemplified by akey defined by certain claimed structuralcharacteristics which correspond to the claimedfeatures of a lock to be used with the claimed keyNote also the examples contained in Chapter 10 ofthe International Search and PreliminaryExamination Guidelines which can be obtained fromthe Patent Examinerrsquos Toolkit or WIPOrsquos website(wwwwipointpctentextsgdlineshtml)

A process is ldquospecially adaptedrdquo for the manufactureof a product if the claimed process inherentlyproduces the claimed product with the technicalrelationship being present between the claimedprocess and the claimed product The expressionldquospecially adaptedrdquo does not imply that the productcould not also be manufactured by a differentprocess

An apparatus or means is specifically designed forcarrying out the process when the apparatus or meansis suitable for carrying out the process with thetechnical relationship being present between theclaimed apparatus or means and the claimed processThe expression specifically designed does not implythat the apparatus or means could not be used forcarrying out another process nor does it imply thatthe process could not be carried out using analternative apparatus or means

Note the determination regarding unity of inventionis made without regard to whether a group ofinventions is claimed in separate claims or asalternatives within a single claim The basic criteriafor unity of invention are the same regardless of themanner in which applicant chooses to draft a claimor claims

If an examiner (1) determines that the claims do notmeet the unity of invention requirement and (2)requires election of a single invention when all of

the claims drawn to the elected invention areallowable (ie meet the requirements of 35 USC101 102 103 and 112) the nonelected invention(s)should be considered for rejoinder Any nonelectedproduct claim that requires all the limitations of anallowable product claim and any nonelected processclaim that requires all the limitations of an allowableprocess claim should be rejoined See MPEP sect82104 Any nonelected processes of making andorusing an allowable product should be considered forrejoinder The examiner should notify applicants ofpotential rejoinder of non-elected process claims byplacing form paragraph 82104 at the end of anylack of unity determination made between a productand a process of making the product or between aproduct and a process of using the product

1 This form paragraph is to be used when making a restrictionrequirement in a national stage application submitted under 35USC 371

2 This form paragraph is to be followed by form paragraphs1806 - 180602 as appropriate and by form paragraphs 1807- 180702 as appropriate

3 All restriction requirements between a productapparatusand a process of making the productapparatus or between aproduct and a process of using the product should be followedby form paragraph 82104 to notify the applicant that if allproductapparatus claims are found allowable process claimsthat require all the limitations of the patentable productapparatusshould be considered for rejoinder

4 When all of the claims directed to the elected invention arein condition for allowance the propriety of the restrictionrequirement should be reconsidered to verify that the non-electedclaims do not share a same or corresponding technical featurewith the allowable claims

para 82104 Notice of Potential Rejoinder of Process Claims

The examiner has required restriction between product andprocess claims Where applicant elects claims directed to the

productapparatus and all productapparatus claims aresubsequently found allowable withdrawn process claims thatinclude all the limitations of the allowable productapparatusclaims should be considered for rejoinder All claims directedto a nonelected process invention must include all the limitationsof an allowable productapparatus claim for that processinvention to be rejoined

In the event of rejoinder the requirement for restriction betweenthe productapparatus claims and the rejoined process claimswill be withdrawn and the rejoined process claims will be fullyexamined for patentability in accordance with 37 CFR 1104Thus to be allowable the rejoined claims must meet all criteriafor patentability including the requirements of 35 USC 101102 103 and 112 Until all claims to the electedproductapparatus are found allowable an otherwise properrestriction requirement between productapparatus claims andprocess claims may be maintained Withdrawn process claimsthat are not commensurate in scope with an allowableproductapparatus claim will not be rejoined See MPEP sect82104 Additionally in order for rejoinder to occur applicantis advised that the process claims should be amended duringprosecution to require the limitations of the productapparatusclaims Failure to do so may result in no rejoinder Furthernote that the prohibition against double patenting rejections of35 USC 121 does not apply where the restriction requirementis withdrawn by the examiner before the patent issues SeeMPEP sect 80401

189303(e) Documents Received from theInternational Bureau and Placed in a USNational Stage Application File [R-072015]

The national stage application includes documentscommunicated by the International Bureau andsubmissions from applicant Some of the documentsfrom the International Bureau are identified in thissection with a brief note as to their importance tothe national stage application The examiner shouldreview each such document and the important aspectindicated

I THE PUBLICATION OF THE INTERNATIONALAPPLICATION

The publication of the international applicationincludes

(A) a cover page with the applicantinventordata the application data (application number filingdate etc) and the Abstract (and if appropriate afigure of drawing)

(B) the description claims and drawing parts ofthe international application and

(C) the search report (Form PCTISA210) ifavailable

The publication may also include other items as setforth in PCT Rule 48

The cover page is important as a source of the correctapplication data most importantly the filing dateand priority date accorded to the internationalapplication If the international application ispublished in English the Office will use thedescription claims abstract and drawings aspublished in the pamphlet for the US national stageapplication under 35 USC 371 The description

1800-188Rev 072015 October 2015


claims and drawing parts of the internationalapplication reflect the application subject matter onthe international filing date and are important forcomparison with any amendments to check for newmatter The search report reflects the InternationalSearching Authorityrsquos opinion regarding the priorart

The abstract is reproduced on the cover page of thepublication even though it appears on a separatesheet of the international application in accordancewith PCT Rule 114(a) The requirement of 37 CFR152(b) that the abstract ldquocommence on a separatephysical sheet or electronic pagerdquo does not apply tothe copy of the published international applicationcommunicated to the designated Offices by theInternational Bureau under PCT Article 20Accordingly it is improper for the examiner of theUS national stage application to require theapplicant to provide an abstract commencing on aseparate sheet if the abstract does not appear on aseparate sheet in the publication of the internationalapplication Unless the abstract is properly amendedunder the US rules during national stage processingthe abstract that appears on the cover page of thepublished international application will be theabstract published by the USPTO under 35 USC122(b) and in any US patent issuing from theapplication

II THE INTERNATIONAL PRELIMINARYEXAMINATION REPORT AND THEINTERNATIONAL PRELIMINARY REPORT ONPATENTABILITY (CHAPTER I AND II)

When an international preliminary examination isperformed by an International PreliminaryExamining Authority (IPEA) an internationalpreliminary examination report (IPER) is preparedon Form PCTIPEA409 by the IPEA and sent to theelected Offices This report reflects the IPEArsquosnon-binding opinion regarding novelty inventivestep and industrial applicability The IPER bears thetitle ldquoInternational Preliminary Report onPatentability (Chapter II of the Patent CooperationTreaty)rdquo

If the applicant did not timely file a demand forinternational preliminary examination with the IPEAthen an ldquoInternational Preliminary Report on

Patentability (Chapter I of the Patent CooperationTreaty)rdquo reflecting the International SearchingAuthorityrsquos (ISArsquos) non-binding opinion regardingnovelty inventive step and industrial applicabilityis sent to the designated Offices

The examiner may adopt any portion or all of thereport on patentability of the IPEA or ISA uponconsideration in the national stage so long as it isconsistent with US practice The first Office actionon the merits should indicate the report onpatentability of the IPEA or ISA has been consideredby the examiner The indication may be a mereacknowledgement

The IPER may include annexes ie amendmentsto the international application that were made duringthe international phase See MPEP sect 189301(a)(3)These annexes will be placed in the US nationalstage application file Consequently if theinternational application has been extensivelyamended during the international stage there maybe a number of different copies of the descriptionclaims and drawings present in the national stageapplication file The IPER may be consulted in BoxNo I ldquoBasis of the reportrdquo to determine what pagesthe report was based upon Using the IPER as aroadmap of what happened during Chapter IIexamination will help determine which versionshould be examined

Original sheets substitute sheets rectified sheetsand sheets that were incorporated by reference andincluded as part of the application examined underChapter II are listed in the IPER as ldquooriginallyfiledfurnishedrdquo Replacement sheets showingamendments made under PCT Article 19 or 34 andconsidered during Chapter II are also listed SeeMPEP sect 1879 If the IPER was established in alanguage other than English the International Bureauwill translate the IPER into English However theInternational Bureau will not translate the annexesto the IPER into English Unless proper and timelytranslations are furnished by the applicant foreignlanguage annexes will be considered canceled SeeMPEP sect 189301(a)(3) All replacement sheets inthe international application are marked with theinternational application number and the date ofreceipt in the upper right-hand corner Replacementsheets that contain changes in format only and are

Rev 072015 October 20151800-189


accepted by the receiving Office are marked asldquoSUBSTITUTE SHEETrdquo at the bottom of the pageReplacement sheets that contain a rectification of anobvious error or mistake and are accepted by eitherthe ISA or the IPEA are marked as ldquoRECTIFIEDSHEET (RULE 91)rdquo at the bottom of the pageSheets that were incorporated by reference andaccepted by the receiving Office are marked asldquoINCORPORATED BY REFERENCE (RULE206)rdquo Additionally replacement sheets to theclaims submitted to the International Bureau asArticle 19 Amendments will be marked asldquoAMENDED SHEET (Article 19)rdquo at the bottom ofthe page Furthermore replacement sheets to thedescription claims and drawings submitted to theIPEA as Article 34 Amendments will be marked asldquoAMENDED SHEETrdquo at the bottom of the pageThe IPER will indicate in ldquoBox No I Basis of theReportrdquo that claim nos or pages submitted undereither PCT Article 19 or 34 have been consideredand will indicate the date they were received and thereplacement sheets will be annexed to the IPER TheNOTIFICATION OF ACCEPTANCE OFAPPLICATION UNDER 35 USC 371 AND 37CFR 1495 (Form PCTDOEO903) should also beconsulted as it will indicate if the annexes or theirtranslation have not been entered

III THE PRIORITY DOCUMENT

See the discussion in MPEP sect 189303(c)

IV NOTIFICATION OF WITHDRAWAL

If the national stage application papers include anindication that the international application or USdesignation has been withdrawn then the applicationshould be brought to the attention of the Office ofPCT Legal Administration to determine whether thewithdrawal occurred prior to completion of therequirements under 35 USC 371(c) If thewithdrawal occurred prior to completion of therequirements under 35 USC 371(c) then entry intothe US national stage is prohibited See 35 USC366 The indication of withdrawal may appear on aNotification of Withdrawal (PCTIB307 orPCTRO136) a Notification that International

Application Considered to Be Withdrawn (FormPCTRO117) or other notification

189303(e)(1) Title of the Invention[R-082012]

In the absence of an application data sheet (37 CFR176) or preliminary amendment changing the titlethe Office will use the title of the invention thatappears on the first page of the description of thepublished international application (if publishedunder PCT Article 21 in English) or the title thatappears on the first page of the description of theEnglish translation of the international application(if not published under PCT Article 21 in English)in preparing the official filing receipt If the titledoes not appear on the first page of the descriptionand an application data sheet or preliminaryamendment changing the title has not been furnishedthen the title will be taken from the cover page ofthe published international application If applicantfurnishes an application data sheet or preliminaryamendment changing the title the Office will usethe title as indicated in such document in preparingthe official filing receipt If applicant submits bothan application data sheet and a preliminaryamendment the later filed document will governSee 37 CFR 176(d)(1) An application data sheetwill govern over a concurrently filed preliminaryamendment See 37 CFR 176(d)(2)

189303(f) Drawings and PCT Rule 11[R-082012]

The drawings for the national stage application mustcomply with PCT Rule 11 The USPTO may notimpose requirements beyond those imposed by thePatent Cooperation Treaty (eg PCT Rule 11)However the examiner does have the authority torequire new drawings if the drawings were publishedwithout meeting all requirements under the PCT fordrawings

189303(g) Information Disclosure Statementin a National Stage Application [R-072015]

An extensive discussion of Information DisclosureStatement practice is to be found in MPEP sect 609Although not specifically stated therein the duty to

MANUAL OF PATENT EXAMINING PROCEDUREsect 189303(e)(1)

disclose information material to patentability asdefined in 37 CFR 156 is placed on individualsassociated with the filing and prosecution of anational stage application in the same manner as fora domestic national application The averment withrespect to the duty under 37 CFR 156 required under37 CFR 163(b)(3) in an oath or declaration isapplicable to oaths and declarations filed in USnational stage applications See 37 CFR 1497(c)

When an international application is filed under thePatent Cooperation Treaty (PCT) prior artdocuments may be cited by the examiner in theinternational search report andor the internationalpreliminary examination report It is desirable forthe US examiner to consider the documents citedin the international application when examining theUS national stage application or when examiningan application filed under 35 USC 111(a) whichclaims the benefit of the international applicationunder 35 USC 365(a) or (c)

When all the requirements for a national stageapplication have been completed applicant isnotified (Form PCTDOEO903) of the acceptanceof the application under 35 USC 371 includingan itemized list of the items received The itemizedlist includes an indication of whether a copy of theinternational search report and copies of thereferences cited therein are present in the nationalstage file The examiner will consider the documentscited in the international search report and anysupplementary international search report under PCTRule 45 bis without any further action by applicantunder 37 CFR 197 and 198 when both theinternational search report (or supplementaryinternational search report under PCT Rule 45 bis )and copies of the documents are indicated to bepresent in the national stage file The examiner willnote the consideration in the first Office actionThere is no requirement that the examiners list thedocuments on a PTO-892 form See form paragraphs653 654 and 655 (reproduced in MPEP sect 60903)Otherwise applicant must follow the procedure setforth in 37 CFR 197 and 198 in order to ensure thatthe examiner considers the documents cited in theinternational search report

This practice applies only to documents cited in theinternational search report relative to a national stage

application filed under 35 USC 371 It does notapply to documents cited in an internationalpreliminary examination report that are not cited inthe search report It does not apply to applicationsfiled under 35 USC 111(a) claiming the benefit ofan international application filing date

1895 A Continuation Divisional orContinuation- in- Part Application of a PCTApplication Designating the United States[R-072015]

It is possible to file a US national application under35 USC 111(a) during the pendency (prior to theabandonment) of an international application whichdesignates the United States without completing therequirements for entering the national stage under35 USC 371(c) The ability to take such action isbased on provisions of the United States patent law35 USC 363 provides that ldquo[a]n internationalapplication designating the United States shall havethe effect from its international filing date underarticle 11 of the treaty of a national application forpatent regularly filed in the Patent and TrademarkOfficerdquo 35 USC 371(d) indicates that failure totimely comply with the requirements of 35 USC371(c) ldquoshall be regarded as abandonment by theparties thereofrdquo It is therefore clear that aninternational application which designates the UnitedStates has the effect of a pending US applicationfrom the international application filing date untilits abandonment as to the United States The firstsentence of 35 USC 365(c) specifically providesthat ldquo[i]n accordance with the conditions andrequirements of section 120 of this title a nationalapplication shall be entitled to the benefit of thefiling date of a prior international applicationdesignating the United Statesrdquo The condition of35 USC 120 relating to the time of filing requiresthe later application to be filed before the patentingor abandonment of or termination of proceedings onthe first application The filing of a continuationdivisional or continuation-in-part application of aPCT application designating the United States isknown as a ldquobypassrdquo application

Rev 072015 October 20151800-191


Continuation-in-part applications are generally filedin instances where applicants seek to add matter tothe disclosure which is not supported by thedisclosure of the international application asoriginally filed as new matter may not be added toa US national stage application See 37 CFR1121(f)

189501 Handling of and Considerations inthe Handling of Continuations Divisions andContinuations-In-Part of PCT Applications[R-072015]

Pursuant to 35 USC 365(c) a regular nationalapplication filed under 35 USC 111(a) and 37 CFR153(b) (not under 37 CFR 153(d)) may claimbenefit of the filing date of an internationalapplication which designates the United States Thusrather than submitting a national stage applicationunder 35 USC 371 applicant may file acontinuation divisional or continuation-in-part ofthe international (PCT) application under 35 USC111(a) Such applications are often referred to asldquobypassrdquo applications

A typical time line involving a continuing applicationfiled during the pendency of an internationalapplication is illustrated as follows

To obtain benefit under 35 USC 120 and 365(c)of a prior international application designating theUS the continuing application must

(A) include a specific reference to the priorinternational application

(B) be copending with the prior internationalapplication and

(C) have at least one inventor in common withthe prior international application

With regard to (A) if the continuing application wasfiled prior to September 16 2012 the specificreference to the international application requiredunder 35 USC 120 and 365(c) must either becontained in the first sentence(s) of the specificationfollowing the title or included in an application datasheet See 37 CFR 178(d)(2) and 37 CFR 178(h)If the continuing application was filed on or afterSeptember 16 2012 the specific reference to theinternational application required under 35 USC120 and 365(c) must be contained in an applicationdata sheet 37 CFR 178(d)(2) The specific referencemust identify the parent international application byinternational application number and internationalfiling date and indicate the relationship of theapplications (ie continuation continuation-in-partor division) See 37 CFR 178(d)(2) and MPEP sect21102 An example of an appropriate first sentenceof the specification is for example ldquoThis is acontinuation of International ApplicationPCTEP2004000000 with an international filingdate of January 5 2004 now abandonedrdquo Therequired reference must be submitted within the timeperiod provided by 37 CFR 178(d)(3) This timeperiod is not extendable A certified copy of theinternational application (and an English translationof the international application) may be required bythe examiner to perfect the claim for benefit under35 USC 120 and 365(c) if the internationalapplication did not originate in the United States andsuch is necessary for example where an interveningreference is found and applied in a rejection of oneor more claims If the international application waspublished by the International Bureau pursuant toPCT Article 21 then a certified copy would notnormally be necessary

If benefit under 35 USC 119(e) andor under 35USC 120 and 365(c) is being claimed to an earlierfiled national application (or international applicationdesignating the US) via an intermediateinternational application designating the US thenthe intermediate international application mustcontain a specific reference to the earlier applicationas required under 37 CFR 178 The specificreference will usually be included on the cover pageof the published international application andor mayappear in the first sentence(s) of the description ofthe published application A lack of a properreference in the published international application

1800-192Rev 072015 October 2015


does not necessarily mean that a proper reference isnot contained in the intermediate internationalapplication Accordingly the internationalapplication file (if the USPTO was the receivingOffice) may have to be inspected to determinewhether the requirements under 37 CFR 178 weresatisfied after publication of the internationalapplication For example the intermediateinternational application file may contain the specificreference in a separate paper filed after publicationbut during the pendency of the internationalapplication or a decision granting a petition to accepta late benefit claim may be present in the applicationfile See MPEP sect 21104 The examiner may contactthe Office of PCT Legal Administration forassistance

With regard to (B) a US national application isconsidered copending with a prior internationalapplication designating the US if the internationalapplication was pending on the filing date of theUS national application Generally except in caseswhere the international application has beenwithdrawn (either generally or as to the UnitedStates) an international application becomesabandoned as to the United States upon expirationof 30 months from the priority date (ie the prioritydate claimed in the international application or ifno priority is claimed the international filing date)unless a proper submission under 35 USC 371 toenter the US national phase is filed prior to theexpiration of this 30-month period See MPEP sectsect189301(a)(1) and 189302 However if theinternational application is one where the 20-monthperiod from the priority date expired before April 12002 then it was necessary to file a demand electingthe United States prior to the expiration of 19 monthsfrom the priority date in order to extend theinternational phase to 30 months from the prioritydate If such a demand was not timely filed thenunder former 37 CFR 1494 such an internationalapplication became abandoned at the expiration of20 months from the priority date unless a propersubmission under 35 USC 371 to enter the USnational phase was made prior to the expiration of20 months from the priority date Accordingly ifthe international application is not subject to thefiling of a demand in order to delay entry into theUS national phase to 30 months from the prioritydate then a national application filed prior to the

expiration of this 30 month period will be copendingwith the international application unless theinternational application was withdrawn eithergenerally or as to the United States prior to the filingof the national application To determine whetherthe application was withdrawn the examiner musteither review the Home Copy of the internationalapplication file (if the USPTO was the receivingOffice) or require applicant to certify that theinternational application was not withdrawn orconsidered to be withdrawn either generally or asto the United States prior to the filing date of thenational application claiming benefit under 35 USC120 and 365(c) to such international application Inorder to expedite examination applicant shouldcertify at the time of filing a national applicationclaiming benefit under 35 USC 120 and 365(c) toan international application that the internationalapplication has not been withdrawn If the nationalapplication claiming benefit to the internationalapplication was filed after the expiration of this30-month period then there will be no copendencyin the absence of a timely and proper submission toenter the US national phase under 35 USC 371The existence of a national stage application maybe checked through PALM and the records of thenational stage application should be consulted toverify copendency Additionally if the 20-monthperiod from the priority date of the internationalapplication expired before April 1 2002 and thenational application claiming benefit under 35 USC120 and 365(c) was filed later than 20 months fromthe priority date of the international application theapplicant may be required to submit proof of thefiling of a demand electing the United States within19 months from the priority date This proof may bein the form of a copy of the ldquoNotification of Receiptof Demand by Competent International PreliminaryExamining Authorityrdquo (Form PCTIPEA402)showing the demand was received prior to theexpiration of 19 months from the priority date anda copy of the ldquoNotification Concerning ElectedOffices Notified of Their Electionrdquo (FormPCTIB332) showing the election of the UnitedStates If the parent international application wasnot copending (ie abandoned or withdrawn)benefit under 35 USC 120 is not possible
