IN THE UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF TEXAS DALLAS DIVISION GALDERMA LABORATORIES, L.P., GALDERMA S.A., and GALDERMA RESEARCH & DEVELOPMENT, S.N.C., v. Plaintiffs, ACTAVIS LABORATORIES UT, INC., TEVA PHARMACEUTICALS USA, INC., and TEVA PHARMACEUTICAL INDUSTRIES LTD., Defendants. CIVIL ACTION NO. COMPLAINT FOR PATENT INFRINGEMENT Plaintiffs GALDERMA LABORATORIES, L.P., GALDERMA S.A., and GALDERMA RESEARCH & DEVELOPMENT, S.N.C. (collectively, "Galderma" or "Plaintiffs") file this Complaint for patent infringement against Defendants ACTAVIS LABORATORIES UT, INC., TEVA PHARMACEUTICALS USA, INC., and TEVA PHARMACEUTICAL INDUSTRIES LTD. (collectively, "Actavis" or "Defendants") as follows: PARTIES 1. Galderma Laboratories, L.P. ("GLP") is a Texas limited partnership with its principal place of business at 14501 North Freeway, Fort Worth, Texas 76177. As Galderma S.A. s ("GSA") exclusive sub-licensee, GLP holds the exclusive right to use, manufacture, and sell Galdermaˈs patented products in the United States, including Epiduo Forte Gel, under FDA approval of New Drug Application ("NDA") No. 207917, approved July 15, 2015. Moreover, COMPLAINT FOR PATENT INFRINGEMENT PAGE 1

GLP is responsible for seeking regulatory approvals of Galdermaˈs products in the United States, and is the sole owner of NDA No. 207917. 2. GSA is a Swiss company with its principal place of business at World Trade Center, Avenue de Gratta-Paille 2, 1018 Lausanne, Switzerland. As Galderma Research & Development, S.N.C.ˈs ("GR&D") exclusive licensee, GSA holds exclusive rights to use, manufacture, and sell Galderma s patented products outside of France, including Epiduo Forte (adapalene and benzoyl peroxide) Gel, 0.3% / 2.5% ("Epiduo Forte Gel"). GSAˈs exclusive license also includes the right and authority to grant an exclusive sub-license, which GSA has granted to GLP as described above. 3. GR&D is a French corporation with its principal place of business at 2400 Route Des Colles, Les Templiers, Biot, France 06410. GR&D is the current owner of U.S. Patent No. 8,445,543 (the "ˈ543 Patent"), U.S. Patent No. 8,785,420 (the "ˈ420 Patent"), and U.S. Patent No. 8,809,305 (the "ˈ305 Patent"). A copy of the ˈ543 Patent is attached as Exhibit "A." A copy of the ˈ420 Patent is attached as Exhibit "B." A copy of the ˈ305 Patent is attached as Exhibit "C." 4. Epiduo Forte Gel is a topical ointment prescription drug that combines a retinoid (adapalene) and an antimicrobial (benzoyl peroxide) for the treatment of acne vulgaris (including severe acne) in people who are at least 12 years old. 5. Actavis Laboratories UT, Inc. ("Actavis UT") is a corporation organized and existing under the laws of the State of Delaware, with its principal place of business at 577 Chipeta Way, Salt Lake City, Utah 84108. Actavis UT may be served with process by and through its registered agent for service of process, Corporate Creations Network Inc., at 3411 Silverside Road #104 Rodney Building, Wilmington, Delaware 19810. Actavis UT is an indirect COMPLAINT FOR PATENT INFRINGEMENT PAGE 2

wholly-owned subsidiary of Teva Pharmaceuticals USA, Inc. ("Teva USA") and acts at the direction of, under the control of, and for the benefit of Teva USA. 6. Teva USA is a corporation organized and existing under the laws of the State of Delaware, with its principal place of business at 1090 Horsham Road, North Wales, Pennsylvania, 19454. Teva USA may be served with process by and through its registered agent for service of process, Corporate Creations Network Inc., at 3411 Silverside Road #104 Rodney Building, Wilmington, Delaware 19810. Teva USA is a wholly-owned subsidiary of Teva Pharmaceutical Industries Ltd. ("Teva Israel"), and acts at the direction of, under the control of, and for the benefit of Teva Israel. 7. Teva Israel is an Israeli company with its principal place of business at 5 Basel Street, Petach Tikva, 4951033, Israel. On August 2, 2016, Teva Israel purchased Allergan plcˈs generic pharmaceuticals business, including Actavis UT. Teva Israel may be served with process by and through its agent in the United States, Teva USA, at 1090 Horsham Road, North Wales, Pennsylvania, 19454. 8. Actavis UT, Teva USA, and Teva Israel work in active concert with respect to the development, regulatory approval, importing, marketing, sale, and distribution of pharmaceutical products, including the product described in Abbreviated New Drug Application No. 209641 (the "ANDA"). JURISDICTION AND VENUE 9. This is a complaint for patent infringement. This Court has jurisdiction over the subject matter of the claims asserted pursuant to 28 U.S.C. 1331 and 1338(a). Venue in this Court is proper under 28 U.S.C. 1391 and 1400(b). COMPLAINT FOR PATENT INFRINGEMENT PAGE 3

10. This Court has personal jurisdiction over Actavis UT, Teva USA, and Teva Israel, because these entities file ANDAs, including the ANDA at issue here, for the purpose of collectively manufacturing, importing, offering for sale, selling, and/or distributing generic pharmaceutical products throughout the United States, including this judicial district. 11. Actavis UT, Teva USA, and Teva Israel operate as an integrated business, as evidenced by Teva Israelˈs 2017 Form 20-F, which indicates that Teva Israel files a single annual report to the U.S. Securities and Exchange Commission for itself and its subsidiaries, including Teva USA and Actavis UT. 12. Actavis UT, formerly known as Watson Laboratories, Inc., was a party to previous litigation in this district involving the filing of an ANDA to market a generic version of Epiduo Gel (adapalene and benzoyl peroxide gel, 0.1% / 2.5%) in the United States. See Galderma Labs., L.P. v. Watson Pharmaceuticals, Inc. and Watson Laboratories, Inc., 3:12-cv- 02563-K (N.D. Tex.). Moreover, Actavis UT's affiliate, Actavis Mid Atlantic LLC, has also previously been involved in litigation in this district involving the filing of an ANDA to market a generic version of Epiduo Gel in the United States. See Galderma Labs., L.P. v. Actavis Mid Atlantic LLC, 3:12-cv-2038-K (N.D. Tex.). In that matter, this Court also evaluated Galdermaˈs patents covering Epiduo Gel, including the ˈ543 Patent, asserted in this suit. 13. Actavis also submitted the ANDA (an act of infringement under 35 U.S.C. 271(e)(2)) for the infringing product and issued a certification under 21 U.S.C. 355(j)(2)(B) (the "Paragraph IV Certification") the acts which give rise to the instant litigation with knowledge that GLP a company located in this district would be injured by such actions in this district, and delivered its Paragraph IV Certification to GLP in this district. Actavis intends to sell the infringing product in or for distribution in this district upon approval by the FDA. COMPLAINT FOR PATENT INFRINGEMENT PAGE 4

Actavis has thus purposefully targeted its conduct to cause harm in the State of Texas, and particularly in this district. 14. Venue is proper in this district because the claims asserted herein arise out of an act of patent infringement Actavisˈs submission of the ANDA and issuance of the Paragraph IV Certification purposefully targeting a resident of this district, GLP. Further, venue is proper in this district because 21 U.S.C. 355(j)(5)(C)(i)(II) establishes this district as the only proper venue for seeking a declaration of non-infringement or invalidity in connection with the ANDA. BACKGROUND FACTS A. The ˈ543 Patent 15. On May 21, 2013, the USPTO issued the ˈ543 Patent, entitled "Combinations of Adapalene and Benzoyl Peroxide for Treating Acne Lesions," to GR&D. GR&D exclusively licensed the ˈ543 Patent to GSA. GSA exclusively sublicensed its rights under the ˈ543 Patent in the United States to GLP. 16. The ˈ543 Patent is valid, enforceable, and has not expired. B. The ˈ420 Patent 17. On July 22, 2014, the USPTO issued the ˈ420 Patent, entitled "Combination/Association of Adapalene and Benzoyl Peroxide for Treating Acne Lesions," to GR&D. GR&D exclusively licensed the ˈ420 Patent to GSA. GSA exclusively sublicensed its rights under the ˈ420 Patent in the United States to GLP. 18. The ˈ420 Patent is valid, enforceable, and has not expired. COMPLAINT FOR PATENT INFRINGEMENT PAGE 5

C. The ˈ305 Patent 19. On August 19, 2014, the USPTO issued the ˈ305 Patent, entitled "Administration of Adapalene and Benzoyl Peroxide for the Long-Term Treatment of Acne Vulgaris," to GR&D. GR&D exclusively licensed the ˈ305 Patent to GSA. GSA exclusively sublicensed its rights under the ˈ305 patent in the United States to GLP. 20. The ˈ305 Patent is valid, enforceable, and has not expired. D. Epiduo Forte Gel 21. GLP is the exclusive owner of NDA No. 207917 giving it sole permission to market and sell Epiduo Forte Gel in the United States. On July 15, 2015, GLP obtained FDA approval to market Epiduo Forte Gel. The ˈ543 Patent, ˈ420 Patent, and ˈ305 Patent are listed in the FDA publication entitled, "Approved Drug Products With Therapeutic Equivalence Evaluations" (known as the "Orange Book") as covering Epiduo Forte (adapalene and benzoyl peroxide) Gel, 0.3% / 2.5%. 22. GR&D has granted GSA, as exclusive licensee, the exclusive right to use, manufacture, and sell Epiduo Forte Gel outside of France, including the right to sub-license to GLP. 23. GR&D and GSA have granted GLP, as exclusive sub-licensee, the exclusive right to use, manufacture, and sell Epiduo Forte Gel in the United States. E. Actavisˈs Infringement 24. Actavis is in the business of developing, manufacturing, and marketing generic pharmaceutical products. COMPLAINT FOR PATENT INFRINGEMENT PAGE 6

25. Prior to February 15, 2017, Actavis decided to file an application seeking FDA approval to sell a generic version of Epiduo Forte Gel. 26. During the process of preparing such application, Actavis reviewed the ˈ543 Patent, ˈ420 Patent, ˈ305 Patent, and certain commercial and economic information relating to Epiduo Forte Gel. 27. Actavis submitted ANDA No. 209641 seeking approval to engage in the commercial manufacture, use, and sale of generic adapalene and benzoyl peroxide gel, 0.3% / 2.5% (the "Accused Product" or "Infringing Product") prior to the expiration of the ˈ543 Patent, ˈ420 Patent, and ˈ305 Patent. 28. The Accused Product that is the subject of the ANDA will directly and indirectly infringe one or more claims of the ˈ543 Patent, ˈ420 Patent, and ˈ305 Patent. 29. On or about February 15, 2017, Actavis sent the Paragraph IV Certification to GLP in Fort Worth, Texas and to GR&D. Through the Paragraph IV Certification, Actavis first notified Plaintiffs that Actavis had filed the ANDA with the FDA relating to the Accused Product, and that the ANDA includes a certification under 21 U.S.C. 355(j)(2)(A)(vii)(IV) that, in Actavisˈs opinion, the claims of the ˈ543 Patent, ˈ420 Patent, and ˈ305 Patent are invalid, unenforceable, and/or will not be infringed by the commercial manufacture, use, offer for sale, sale, or importation of the Accused Product. 30. Actavis was aware of the ˈ543 Patent, ˈ420 Patent, and ˈ305 Patent when it filed the ANDA and/or sent the Paragraph IV Certification. 31. Plaintiffs have commenced this action within 45 days of the date that they received the Paragraph IV Certification. COMPLAINT FOR PATENT INFRINGEMENT PAGE 7

32. Actavis intends to continue seeking approval of the ANDA from the FDA, and to engage in the commercial manufacture, marketing, and sale of the Accused Product (including commercial marketing and sale of the Accused Product in the State of Texas and this District), in the event that the FDA approves the ANDA. forth herein. COUNT I: INFRINGEMENT OF U.S. PATENT NO. 8,445,543 33. Plaintiffs incorporate paragraphs 1 through 32 above by reference as if fully set 34. The ˈ543 Patent is valid, enforceable, and has not expired. 35. The Accused Product and/or its use as directed infringes at least claim 1 of the ˈ543 Patent. As such, under 35 U.S.C. 271(e)(2)(A), Actavis infringed the ˈ543 Patent by submitting the ANDA seeking permission to commercially manufacture, use, or sell the Accused Product prior to the expiration of the ˈ543 Patent. 36. Actavis will induce infringement of one or more claims of the ˈ543 Patent in violation of Plaintiffsˈ patent rights if the FDA approves the sale of the Accused Product with instructions and labeling that will result in direct infringement of one or more claims of the ˈ543 Patent by users of the Accused Product. 37. Actavis seeks approval of at least one indication for the Accused Product that is claimed in the ˈ543 Patent. 38. Actavis intends that physicians will prescribe, and patients will use, the Accused Product in accordance with the indication(s) sought by Actavis and will therefore infringe one or more claims of the ˈ543 Patent under 35 U.S.C. 271(b). 39. In addition, pursuant to the Drug Price Competition and Patent Term Restoration Act, 21 U.S.C. 355 et seq., Actavisˈs ANDA must include information showing that the COMPLAINT FOR PATENT INFRINGEMENT PAGE 8

Accused Product (1) contains the same active ingredients as Epiduo Forte Gel [21 U.S.C. 355(j)(2)(A)(II)]; (2) has the same route of administration, dosage form, and strength as Epiduo Forte Gel [21 U.S.C. 355(j)(2)(A)(iii)]; and (3) is bioequivalent and/or has the same therapeutic effect as Epiduo Forte Gel [21 U.S.C. 355(j)(2)(A)(iv)]. 40. As such, under 35 U.S.C. 271(e)(2)(A), Actavis has infringed the ˈ543 Patent by submitting the ANDA seeking permission to commercially manufacture, use, or sell the Accused Product prior to the expiration of the ˈ543 Patent. 41. As a result of Actavisˈs infringement, Plaintiffs are entitled to a declaration that the Accused Product infringes the ˈ543 Patent if made, used as directed, sold, offered for sale, or imported during the term of the ˈ543 Patent. 42. Plaintiffs will be substantially and irreparably harmed by Actavisˈs infringing activities unless those activities are enjoined by this Court. Plaintiffs have no adequate remedy at law. 43. As a result of Actavisˈs infringement, Plaintiffs are entitled to permanent injunctive relief, restraining and enjoining Actavis and all those in privity or acting in concert with Actavis from manufacturing, selling, offering to sell, or importing the Accused Product during the term of the ˈ543 Patent, or from otherwise infringing or inducing the infringement of the ˈ543 Patent. forth herein. COUNT II: INFRINGEMENT OF U.S. PATENT NO. 8,785,420 44. Plaintiffs incorporate paragraphs 1 through 43 above by reference as if fully set 45. The ˈ420 Patent is valid, enforceable, and has not expired. COMPLAINT FOR PATENT INFRINGEMENT PAGE 9

46. The Accused Product and/or its use as directed infringes at least claim 1 of the ˈ420 Patent. As such, under 35 U.S.C. 271(e)(2)(A), Actavis infringed the ˈ420 Patent by submitting the ANDA seeking permission to commercially manufacture, use, or sell the Accused Product prior to the expiration of the ˈ420 Patent, 47. Actavis will induce infringement of one or more claims of the ˈ420 Patent in violation of Plaintiffsˈ patent rights if the FDA approves the sale of the Accused Product with instructions and labeling that will result in direct infringement of one or more claims of the ˈ420 Patent by users of the Accused Product. 48.
