2 1859320.3 7/13/2011

3. Personal jurisdiction is proper in this District by virtue of Defendants’ threats of

derives substantial revenue from interstate or international commerce.

4. Venue is proper in this District pursuant to 28 U.S.C. §§ 1391(b) and (c) and

§ 1400(b).

5. There is an actual justiciable case or controversy between ConMed and

Defendants in this district that arises under the patent laws, 35 U.S.C. §§ 101 et seq., by virtue of

Defendants’ accusation that ConMed is infringing its U.S. patent rights.

FACTS

6. Plaintiff ConMed is a New York corporation headquartered at 525 French Road in

Utica, New York that specializes in orthopedics and general surgery products. Since its founding

in 1973 as small, privately held company, ConMed has grown into a large, publicly held and

diversified medical device organization that manufacturers thousands of products and employs

over 3,000 people in multiple manufacturing facilities and sales offices worldwide.

7. Defendant Cosmescu is an individual and the owner of U.S. Patent No. 7,935,109

(the ’109 patent), a copy of which is attached hereto as Exhibit A, which is directed to certain

multifunctional electrosurgery pencils having biopolar electrodes. Defendant I.C. Medical is a

corporation organized and existing under the laws of the Arizona and having a principal place of

business at 2340 West Shangri La Road, Phoenix, Arizona 85029. Defendant Cosmescu is the

founder and President of Defendant I.C. Medical and, upon information and belief, Defendant

I.C. Medical is the exclusive licensee of the ’109 patent and/or has been granted the right to

enforce the ’109 patent against third parties.



3 1859320.3 7/13/2011

8. ConMed in currently offering to sell and selling certain monopolar electrosurgical

pencils throughout the United States, including a monopolar electrosurgical pencil referred to as

the GoldVac® electrosurgery pencil (“the Accused Product”).

9. On or about September 5, 2013, counsel for Defendant I.C. Medical notified

ConMed by written correspondence that, in the opinion of Defendants, the Accused Products

infringe the claims of the ’109 patent. A true and correct copy of the correspondence dated

September 5, 2013 is attached hereto as Exhibit B. In response to correspondence dated

September 15, 2013 from ConMed that disputed the allegations of infringement, Defendant I.C.

Medical against wrote to ConMed on September 30, 2013 and reasserted its claim that ConMed

was infringing the ’109 patent. A true and correct copy of the correspondence dated September

30, 2013 is attached hereto as Exhibit C.

10. Based on Defendants’ threats of infringement, ConMed has a reasonable

apprehension that it will face a patent infringement lawsuit if it continues to offer to sell and sell

the Accused Products, which ConMed is current doing and intends to do in the future.

11. In light of ConMed’s continuing sale of the Accused Products and Defendants’

express accusations that such products are infringing its rights in the ’109 patent, a real and

substantial controversy exists between parties’ having adverse legal interests.

12. ConMed does not have an adequate remedy at law.

DECLARATORY JUDGMENT OF NON-INFRINGEMENT

13. Upon information and belief, the Accused Products do not contain each and every

element of any one claim of the ’109 patent.

14. ConMed is therefore entitled to a declaratory judgment that the claims of the ’109

patent are not infringed.



4 1859320.3 7/13/2011

DECLARATORY JUDGMENT OF INVALIDITY

15. Upon information and belief, the claims of the ’109 patent are invalid under 35

U.S.C. §§ 102, 103 and/or 112.

16. As a result, ConMed is entitled to a declaratory judgment that the claims of the

’109 patent are invalid.

PLAINTIFF DEMANDS A TRIAL BY JURY

WHEREFORE, the plaintiff prays that the Court:

(a) enter judgment that the claims of U.S. Patent No. 7,935,109 are not infringed by

the accused product;

(b) enter judgment that the claims of U.S. Patent No. 7,935,109 are invalid under the

Patent Act, 35 U.S.C. §§ 102, 103 and/or 112;

(c) enter judgment that this is an exceptional case under 35 U.S.C. § 285.

I am writing to address the points you raised in your letter. I appreciate that you did not

have an opportunity to conduct a full analysis, but I wished to advise that I disagree with the

statements you have made following your preliminary review. My client and I continue to

believe that the GoldVac infringes IC Medical' s US patent 7,935 ,109 (the " 109 Patent").

First, I do not agree with your construction of the term "multifunctional". This term doesnot relate to the monopolar/bipolar aspect as you alleged. This term relates to the invented

device having more than one function - i.e. electrosurgery, smoke evacuation, etc. In this

respect, please refer to the claim language, which is itself incompatible with your interpretation

of "multifunctional" as meaning "both monopolar and bipolar". In particular, I refer you to

claim 5, which describes "The multifunctional electrosurgery pencil of claim 1 wherein said

electrode is a bipolar electrode." If "multifunctional" could be properly construed as "monopolar

and bipolar", this claim would not have been allowed in its current form , and the claims as a

whole would be internally inconsistent.

In response to your request for a claim chart, please see the attached.

Regarding your allegation of inequitable conduct relating to the ' 109 Patent, we strongly

disagree with the characterizations you have made of our client's actions and the prosecutionhistory. In any event, none of the points you raised would meet the test for inequitable conduct ,

which is set out in the Therasense case. Intent and materiality would be required to be proven.

We do not believe that any Court reviewing the points you have raised, even accepting thecharacterizations you have placed on them, could reasonably conclude that any of them rise to

the level of inequitable conduct.



Daniel S. JonasSeptember 30, 2013

We are therefore confident that if Court proceedings were necessary, the 109 Patentwould be upheld as valid, and the GoldY ac found to infringe.

However, we agree that it makes sense to undertake discussions with one another beforespending further significant funds on litigation. Our client ' s primary focus is ConMed' sinfringing activities of manufacture and sale in the US. However, we do recognize that theCanadian litigation will soon be entering a more cost and time-intensive phase, and it therefore

makes sense to consider a global settlement at this time.

We believe that the specific terms of settlement would be best discussed live, but canprovide the following terms to frame our discussion. We believe these terms would provide a

reasonable, global resolution of the ongoing disputes:

• IC Medical to refrain from commencing further litigation in the US against ConMed inrespect of the 109 Patent and any patents claiming priority to that patent;

• ConMed would be permitted to continue the manufacture and sale of the GoldVac withinthe US, but would transition out of the Canadian market until the relevant Canadianpatents expire;

• The relevant releases would be signed to discontinue the Canadian case;

• ConMed would pay a one time $125,000 fee for a fully paid-up license for all of IC

Medical's existing US patents which could read on the currently existing GoldVac andany patent applications claiming priority from those patents.

• All parties to bear their own legal costs to date.

We look forward to discussing the above with you .
