AMGEN, INC.,

Plaintiff,

v. Civil No. 24-9052 (CPO/EAP)

CELLTRION USA, INC.,

Defendant.

OPINION

This matter comes before the Court on Plaintiff Amgen Inc.’s (“Amgen”) application pursuant to 28 U.S.C. § 1782 for an order to take discovery for use in a foreign proceeding. See ECF No. 1. Amgen filed a brief in support. See ECF No. 1-3 (“Amgen Br.”). Defendant Celltrion USA, Inc. (“Celltrion USA”) opposes Amgen’s requested relief. See ECF No. 10 (“Celltrion Br.”). Amgen has filed a reply brief. See ECF No. 21 (“Amgen Reply”). The Court has considered the parties’ submissions and decides this matter without oral argument pursuant to Federal Rule of Civil Procedure 78(b) and Local Civil Rule 78.1. For the following reasons, Amgen’s application will be GRANTED. FACTUAL BACKGROUND A. Amgen’s Development and Patent of Denosumab Amgen is a biotechnology company incorporated in Delaware and headquartered in Thousand Oaks, California. ECF No. 1-8, Declaration of Hyun-Jin Chang (“Chang Decl.”) ¶ 4. In 2010, Amgen received Food and Drug Administration (“FDA”) approval for Prolia and XGEVA. ECF No. 1-4, Certification of Charles H. Chevalier (“Chevalier Certif.”) ¶ 4 & Ex. C (Prolia product label). Physicians prescribe Prolia to treat patients with a high risk of bone fractures, including patients with osteoporosis. Chang Decl. ¶ 4; Chevalier Certif. ¶ 4 & Ex. C. XGEVA is prescribed to prevent skeletal-related events (e.g., fractures or spinal cord compression) in cancer patients whose cancer has spread to the bone, as well as to treat certain types of tumors.

Chang Decl. ¶ 4; Chevalier Certif. ¶ 3 & Ex. C. The active ingredient in both drugs is a monoclonal antibody named denosumab. Chang Decl. ¶¶ 2, 4; Chevalier Cert. ¶ 3 & Ex. B (FDA Imports Entry Data Search). According to Amgen, its scientists have spent decades and millions of dollars creating the denosumab antibody and developing Prolia and XGEVA. Chang Decl. ¶ 4. In addition, Amgen’s scientists have made significant advancements in the manufacturing processes for these products to ensure consistency, quality, efficacy, and safety. Id.; Amgen Br. at 8. In relation to its denosumab products, Amgen maintains an extensive portfolio of patents covering both the products and the manufacturing processes. Id. ¶ 5. In particular, Amgen holds South Korean Patent No. 10-1038585 (the “’585” Patent), which relates to and claims denosumab—the active ingredient in Prolia and XGEVA—and is the counterpart of Amgen’s U.S.

Patent No. 7,354,736 (the “Boyle Patent”). Id. ¶¶ 5, 7. According to Amgen, the ’585 Patent is valid and listed on the Green List of the South Korean Ministry of Food and Drug Safety (“MFDS”) in connection with “Prolia Pre-filled Syringe (denosumab)” and “XGEVA Injection (denosumab).” Id. The ’585 patent expires on March 17, 2025. Id. Amgen also has several South Korean patents covering manufacturing processes that can be used to produce denosumab (i.e., the “Korean Manufacturing Patents”), which also have counterpart U.S. Patents. Id. ¶ 7. These Korean Manufacturing Patents expire on various dates between 2025 and 2035. Id. ¶ 8. B. Alleged Infringing Activities of Celltrion Celltrion Inc. is a biotechnology company incorporated and headquartered in South Korea. Id. ¶ 6. Celltrion, Inc. is the parent company of Celltrion USA, the current application’s target. Id.; ECF No. 1 at 1 (Application). Celltrion USA is a Delaware corporation with its principal place

of business in Jersey City, New Jersey (collectively, Celltrion, Inc. and Celltrion USA are referred to as “Celltrion”). Id.; Amgen Br. at 9; Celltrion Br. at 4. Celltrion has developed a follow-on drug product (biosimilar) of Prolia/XGEVA using the active ingredient denosumab with the name “CT-P41,” which it is now preparing for global launch. Chang Decl. ¶ 6. Celltrion filed a Biologics License Application (“BLA”) with the FDA seeking regulatory approval to market its biosimilar CT-P41 in the United States. Compl., Amgen, Inc. v. Celltrion, Inc., Civ. A. No. 24-6497, ECF No. 1 (“Compl.”) On May 2, 2024, Celltrion sent a Notice of Commercial Marketing to Amgen in the United States, indicating that Celltrion may begin to commercially market its biosimilar as soon as October 29, 2024. Chang Decl. ¶ 6. Amgen alleges that publicly available records indicate that Celltrion has already imported its biosimilar,

CT-P41, into the United States. Chevalier Certif. ¶ 3, Ex. B. Amgen further claims that, through these actions, Celltrion seeks to market its biosimilar before Amgen’s U.S. and South Korean Patents expire. Chang Decl. ¶¶ 6, 8; Amgen Br. at 4. C. Amgen’s Pending and Anticipated Litigation Against Celltrion On May 28, 2024, Amgen and its affiliate, Amgen Manufacturing Limited LLC, filed a patent infringement complaint against Celltrion, Inc. and Celltrion USA in this Court, seeking a declaratory judgment that Celltrion will infringe a number of U.S. patents covering denosumab and the manufacturing methods that may be used to produce denosumab. Chang Decl. ¶ 7; see Compl., ECF No. 1, Amgen, Inc. v. Celltrion, Inc., Civ. A. No. 24-6497. Amgen has also identified the South Korean counterparts of a subset of the U.S. patents that have been asserted in the underlying patent litigation in this Court against Celltrion: United States Patent South Korean Counterpart/Relative U.S. 7,364,736 (the “Boyle Patent”) KR10-1038585 (the “’585 Patent”) U.S. 7,928,205 (the “Dillon Patent”) KR10-1370253 U.S. 9,320,816 (the “Zhou Patent”) KR10-1307697 U.S. 10,106,829 (the “Gupta Patent”) KR10-2301034 KR10-2410393 KR10-2519540 U.S. 10,167,492 (the “Leiske Patent”) KR10-2623965 U.S. 10,513,723 (the “Kang Patent”) KR10-2381791 U.S. 10,538,397 (the “Gefroh Patent”) KR10-2370714 KR10-2504829

Chang Decl. ¶ 7. On July 1, 2024, Amgen filed a patent infringement preliminary injunction action before the Seoul Central District Court (the “South Korean Court”), under the caption Amgen Fremont, Inc. et al. v. Celltrion, Inc., Case. No. 2024 Kahap 20960 (“South Korean Proceedings”). Chang Decl. ¶¶ 2, 9. In the South Korean Proceedings, Amgen Inc. and Amgen Fremont, Inc. seek a preliminary injunction to prohibit Celltrion from manufacturing and stockpiling denosumab biosimilar drug substance and drug products—which allegedly infringe the ’585 Patent—in South Korea. Id. Because South Korean law requires that preliminary injunction proceedings be brought separately from a main patent infringement action seeking permanent relief, Amgen anticipates filing a main action in South Korea, seeking a permanent injunction and damages based upon Celltrion’s infringement of the ’585 Patent. Id. ¶¶ 2, 10-11; ECF No. 1-9, Declaration of Sung Jai Choi (“Choi Decl.”) ¶ 7. Amgen further contemplates additional preliminary injunction and main action proceedings in South Korea to prevent the ongoing and/or planned infringement of Amgen’s South Korean Manufacturing Patents. Chang Decl. ¶ 2. To prevail in a South Korean preliminary injunction action, the patentee has the burden to show likelihood of success on the merits of the infringement claim and that irreparable harm will

imminently result if the preliminary injunction is not granted. Choi Decl. ¶ 8. While a preliminary injunction action may be filed with only prima facie evidence of infringement, South Korea limits litigation discovery, thereby requiring a patentee to obtain and present the evidence it needs to prove infringement and harm through its own devices, without expecting discovery from the alleged infringer. Id. ¶ 9.
