Slides to Accompany Artful Prior Art
Derwent GENESEQ DatabaseCollection of patented DNA sequences10 or more base pairsCoverage from 1981Feb. 2001: 1,000,000 sequencesFeb. 2002: 2,000,000 sequencesOct. 2003: 3,900,000 sequences
U.S. Patent No. 6,074,81612. The purified preparation of claim 1 wherein the oligonucleotide comprises a contiguous sequence of at least 8 nucleotides complementary to either strand of the nucleotide residue sequence depicted in FIG. 62.
Figure 62Strand A has 9,185 bases, beginning with:5-CACTCCACCATGAATCACTCCCCTGTG AGGAACTACTGTCTTCACGCAGAAAGCGTCTAG.Strand B is Strand As reverse complement.Claim covers 18,356 oligonucleotides (minus duplicates)But there are only 48 = 65,536 possible oligonucleotides with 8 bases!
What is Patented?An isolated and purified DNA molecule.
Why is it Patentable?Statutory lawCase lawPatent Office Guidelines
35 U.S.C. 101 (1952)Whoever invents or discovers any new and useful process, machine, manufacture, or combination of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title.
35 U.S.C. 103 (1952)(a) A patent may not be obtained if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art (c) Patentability shall not be negatived by the manner in which the invention was made.
Patent-Defeating DisclosuresA patent may not claim subject matter that was described in a printed publicationbefore the date of invention; ormore than one year before the application filing date. 35 U.S.C. 102(a)
Some DNA Disclosure ProgramsImmediate publication of DNA sequences in public databasesHuman Genome Project (Genbank)Merck Gene Index (ESTs)Filing of statutory invention registrations: 35 U.S.C. 157SNP Consortium
LimitationsPublication of sequence information does not invalidate claims to subsequences per sePublication of ESTs does not invalidate claims to full-length genes or subsequences thereofIn re Deuel; In re Bell
Another Approach:Quiet PublicationIs a doctoral thesis a printed publication under 102(b)?Yes, if it is publicly accessible. In re Hall.General library practice may be relied upon to establish an approximate time for thesis accessibility.Library directors affidavit: The dissertation most probably was available for general use toward the beginning of the month of December, 1977.
In re HallAn applicant has constructive knowledge of all properly indexed, cataloged and shelved library materials worldwide.
Described in a Printed PublicationTo anticipate a claim to one or more chemical compounds, a single printed publication must:specifically describe a compound within the scope of the claimdisclose a method of making the compound that enables one of ordinary skill in the art to do sorecite at least one significant useful property ( 101 utility requirement need not be met)It is not necessary that the disclosed compound actually have been made
Previous WorkGeneral methods of making and using oligonucleotides of arbitrary sequence are well known and described in the literature.But specific oligonucleotides are not described in this literature, so there is no 102(a) bar
102(a) RequirementsA 102(a) reference must include:A specific description of the subject matter andInstructions that will enable an ordinary practitioner to make and use the subject matterNot necessary to have actually made or used the subject matterA single copy in a public library counts as publicationSolution: Describe 11 million DNA sequences, and general methods of making and using them, on a single CD-ROM
The CD-ROMOn the Preparation and Utilization of Isolated and Purified Oligonucleotides As described in U.S. Patent No. 5,808,022 (issued Sept. 15, 1998) (William D. Huse), oligonucleotide synthesis proceeds via linear coupling of individual monomers in a stepwise reaction. The reactions are generally performed on a solid phase support . . .
The CD-ROMBased on the the disclosures herein and the knowledge of a person of ordinary skill in the art, it will be apparent to such a person how to make and use an isolated and/or purified oligonucleotide characterized by any of the following nucleotide sequences:
