Case 2:11-cv-03995-WHW -MCA Document 7 Filed 09/12/11 Page 6 of 17 PageID: 62 Lupin Ltd. admits that the Reference Listed Drug product that is the basis for Lupin Ltd. s ANDA is Prezista. Lupin Ltd. further states that its ANDA contains information and data required by FDA for the submission of an ANDA. Lupin Ltd. denies all remaining allegations of Paragraph 13. 14. The government and the University of Illinois received letters from Lupin, dated June 3, 2011, and attached memoranda (collectively, Lupin s Notifications), stating that Lupin had included certifications in its ANDA, pursuant to 21 U.S.C. 355(j)(2)(A)(vii)(IV), that the 506 patent is invalid, unenforceable, and/or will not be infringed by the commercial manufacture, use, or sale of Lupin s Product (the Paragraph IV certifications). The Plaintiffs are filing this complaint within the 45 day interval of receipt of Lupin s ANDA as specified by 21 U.S.C. 355(c)(3)(C). Lupin Ltd. admits that, in a letter dated June 3, 2011, it gave written notification to, among others, Plaintiffs that it had filed an ANDA with FDA seeking approval for Darunavir Ethanolate Tablets, which ANDA contains a certification pursuant to 21 U.S.C. 355(j)(2)(A)(vii)(IV) stating, among other things, that in its opinion and to the best of its knowledge, the 506 patent is invalid, unenforceable and/or will not be infringed by the manufacture, use, sale, offer for sale and/or importation of its proposed ANDA products.

Plaintiffs reallege and incorporate by reference the allegations of paragraphs 1-14 of this Complaint. Lupin Ltd. restates and incorporates by reference its answers to the allegations of Paragraphs 1 through 14 as though fully set forth herein. 16. Under 35 U.S.C. 271(b), [w]hoever actively induces infringement of a patent shall be liable as an infringer. - 6 -

Case 2:11-cv-03995-WHW -MCA Document 7 Filed 09/12/11 Page 7 of 17 PageID: 63 Paragraph 16 states legal conclusions to which no answer is required. To the extent an answer is required, denied. 17. The proposed generic versions of Prezista as described in ANDA No. 202-073, if utilized in treatment according to their proposed indications, will infringe every limitation of at least one claim of the 506 patent. 18. Lupin is thus knowingly, intentionally, and deliberately seeking approval of a product that, if used according to its indications, will infringe the 506 patent. 19. In addition, if ANDA No. 202-073 is approved, Lupin will be knowingly, intentionally, deliberately and actively involved in inducing treating physicians, among others, to utilize Lupin s Product in a manner that infringes the 506 patent. 20. Lupin is therefore liable under 35 U.S.C. 271(e)(2) for inducement of infringement of the 506 patent. COUNT TWO: CONTRIBUTORY INFRINGEMENT OF THE 506 PATENT 21. Plaintiffs reallege and incorporate by reference the allegations of paragraphs 1-20 of this Complaint.

The proposed generic versions of Prezista as described in ANDA No. 202-073, if utilized in treatment according to their proposed indications, will infringe every limitation of at least one claim of the 506 patent. 23. Lupin is thus knowingly, intentionally, and deliberately seeking approval of a product that, if used according to its indications, will infringe the 506 patent. - 7 -

Case 2:11-cv-03995-WHW -MCA Document 7 Filed 09/12/11 Page 8 of 17 PageID: 64 24. Lupin s commercial manufacture, use, offer to sell, or sale of Lupin s Product within the United States, or importation of Lupin s Product into the United States while knowing Lupin s Product to be especially made or especially adapted for use is an infringement of the 506 patent, and not a staple article or commodity of commerce suitable for substantial noninfringing use during the term of the 506 patent will contributorily infringe the 506 patent under 35 U.S.C. 271(a), (b), and/or (c). 25. The Plaintiffs will be substantially and irreparably harmed if Lupin is not enjoined from infringing the 506 patent. 26. The Plaintiffs have no adequate remedy at law. 27. This case is an exceptional one, and Plaintiffs are entitled to an award of attorneys fees under 35 U.S.C. 285. * * * Lupin Ltd. denies all remaining allegations not specifically admitted herein. Lupin Ltd. further denies that Plaintiffs are entitled to the relief requested, or to any relief whatsoever. Lupin Ltd. respectfully requests that the Court: (a) dismiss the Complaint with prejudice; (b) enter judgment in favor of Lupin Ltd.; (c) award Lupin Ltd. the reasonable attorneys fees and costs of defending this action pursuant to 35 U.S.C. 285; and (d) award Lupin Ltd. such further relief as the Court deems just and appropriate. - 8 -

Case 2:11-cv-03995-WHW -MCA Document 7 Filed 09/12/11 Page 9 of 17 PageID: 65 SEPARATE DEFENSES Without prejudice to the denials set forth in its Answer, without admitting any averments of the Complaint not otherwise admitted, and without undertaking any of the burdens imposed by law on the Plaintiffs, Lupin Limited ( Lupin Ltd. ) avers and asserts the following separate defenses to the Complaint: First Defense The claims of U.S. Patent No. 7,470,506 B1 ( the 506 patent ) are invalid for failure to comply with one or more of the conditions for patentability set forth in Title 35 of the United States Patent Code. Second Defense The manufacture, use, sale, offer for sale and/or importation of Lupin Ltd. s proposed Darunavir Ethanolate Tablets that are the subject of its Abbreviated New Drug Application ( ANDA ), would not infringe, either directly or indirectly, any valid and enforceable claim of the 506 patent, either literally or under the doctrine of equivalents. Third Defense Lupin Ltd. has not and will not induce or contribute to infringement of any valid and enforceable claim of the 506 patent.
