MEMORANDUM OPINION December 4, 2025 Wilmington, Delaware

GREGORY B. WILLIAMS UNITED STATES DISTRICT JUDGE

Plaintiffs Merck KGaA, Merck Serono SA, and Ares Trading SA (collectively, “Plaintiffs” or “Merck”) filed suit against Defendants Hopewell Pharma Ventures, Inc. (“Hopewell”), Aurobindo Pharma USA Inc., Aurobindo Pharma Limited, Apotex Inc., and Apotex Corp. (collectively, “Defendants”), alleging infringement of U.S. Patent Nos. 7,713,947 and 8,377,903 (together, “the Asserted Patents”).' On December 23, 2024, the Court granted Hopewell’s Emergency Motion to Stay the Case Pending Resolution of any Appeal of IPR2023-00480 and IPR2023-00481 (‘the IPR Appeals”)” (D.1. 196) (“the Emergency Motion to Stay the Case”), and tolled the 30-month “statutory stay of FDA[*] approval of Hopewell’s ANDAJ"*] product” (“the Regulatory Stay”). (D.I. 223 at 1). On January 16, 2025, the Court stayed Merck’s action against the remaining Defendants. (See D.I. 236 at 2).° Pending before the Court is Hopewell’s Emergency Motion to Lift the Regulatory Stay (D.I. 252) (“Hopewell’s Motion’), which has been fully briefed (D.I. 252; D.I. 258; D.I. 261). For the following reasons, the Court denies Hopewell’s Motion.

Merck’s individual actions against the Defendants were consolidated. See Merck KGaA v. Hopewell Pharma Ventures, Inc., C.A. No. 22-1365-GBW-CJB, 2024 WL 2973034, at *1 n.l (D. Del. June 13, 2024), report and recommendation adopted, C.A. No. 22-1365- GBW-CIJB, 2024 WL 3967463 (D. Del. Aug. 28, 2024). IPR2023-00480 and IPR2023-00481 invalidated the claims of the Asserted Patents that Merck asserts in this action. The “FDA” refers to the United States Food and Drug Administration. “ANDA” refers to an Abbreviated New Drug Application. ° The Court will refer to this stay as “the Hopewell Stay.” ie,

I. BACKGROUND “Plaintiffs allege that Defendants have infringed [various patent] claims .. . by submitting their respective Abbreviated New Drug Applications seeking approval to market generic versions of Plaintiffs’ MAVENCLAD® product.” (2024 WL 2973034, at *1 (citing D.I. 67 at 1, 7 n.5); see also D.I. 1 ¥ 1). Hopewell filed successful inter partes review (“IPR”) challenges against Merck’s asserted patent claims. See Hopewell Pharma Ventures, Inc. v. Merck Serono S.A., No. IPR2023-00480, Paper 62, 2024 Pat. App. LEXIS 3751 (P.T.A.B. Sept. 18, 2024); Hopewell Pharma Ventures, Inc. v, Merck Serono S.A., No. IPR2023-00481, Paper 62, 2024 Pat. App. LEXIS 3752 (P.T.A.B. Sept. 18, 2024); (see also D.I. 233 at 5; D.I. 197 at 1; D.I. 195 at 1).° As noted below, the Court stayed Merck’s actions in light of Hopewell’s successful IPR challenges. A. Hopewell’s Emergency Motion to Stay On November 27, 2024, Hopewell filed its Emergency Motion to Stay the Case. (D.I. 196). Therein, Hopewell “move[d] to stay this matter pending the resolution of any appeal of IPR2023- °

00480 and IPR2023-00481, in which the PTAB[’] [held that] the asserted claims [of] U.S. Patent Nos. 7,713,947 and 8,377,903 [are] invalid as obvious.” (D.I. 196 at 1). In its accompanying opening brief, Hopewell contended that “[t]he Court should grant a stay so that the parties and the Court can stop devoting resources to a case in which no trial is necessary.” (D.I. 197 at 1; see also

6 “The Leahy-Smith America Invents Act, 35 U.S.C. § 100 et seq., establishes a process called ‘inter partes review.’ Under that process, the United States Patent and Trademark Office (PTO) is authorized to reconsider and to cancel an issued patent claim in limited circumstances.” Oil States Energy Servs., LLC v. Greene’s Energy Grp., LLC, 584 US. 325, 328-29 (2018); see also SNIPR Techs. Lid. v. Rockefeller Univ., 72 F 4th 1372, 1381- 82 (Fed. Cir. 2023). “[O]nce a claim is already and finally held unpatentable as a result of an IPR, the claim is subject to a wholly ministerial, inevitable, unreversible cancellation.” Kroy IP Holdings, LLC v. Groupon, Inc., 127 F.4th 1376, 1381 (Fed. Cir. 2025). 7 “PTAB” refers to the Patent Trial and Appeal Board.

id. at 2 (“[A] stay is appropriate despite the late stage of the litigation because there are no issues left to litigate.”)). Merck opposed Hopewell’s Emergency Motion to Stay the Case. (See D.I. 205 at 2). Merck alternatively requested that, “if the Court were to stay the trial, it should at a minimum toll Hopewell’s statutory 30-month stay under 21 U.S.C. § 355G)(5)(B)Gii) for the pendency of the litigation stay.” (/d.). According to Merck, Hopewell’s Emergency Motion to Stay was “‘itself a failure to cooperate in the expeditious resolution of this litigation and thus sufficient reason to toll the statutory stay.” (/d. at 4). This was so, according to Merck, because “Hopewell simply cannot simultaneously cooperate in the expeditious resolution of this litigation and request a stay of the same litigation.” (Ud. at 5). Merck also contended that “a tolling of the statutory stay period comports with the statutory scheme of the Hatch-Waxman Act.” (/d.). Hopewell disagreed. Hopewell responded that there was no “basis for extending the 30-month stay of FDA approval of Hopewell’s ANDA.” (D.L. 207 at 2). According to Hopewell, its “request for a stay to avoid the burden and expense of an unnecessary trial cannot be fairly characterized as a ‘failure to cooperate in the expeditious resolution of th[e] litigation.’” (/d. (alteration in original) (quoting D.I. 205 at 4)). Hopewell also contended that it “will certainly be prejudiced if the FDA determines [that] Hopewell’s ANDA is in condition for approval, but the agency is not free to grant final approval because of an injunction based on invalid patent claims.” (/d.). On December 23, 2024, the Court granted Hopewell’s Emergency Motion to Stay the Case. (D.I. 223 at 1). The Court also granted Merck’s alternative request for tolling. (See id. (“[P]ursuant to 21 U.S.C. § 355q)(S)(B)(Giii), the thirty (30) month statutory stay of FDA approval of Hopewell’s ANDA product is tolled during the pendency of the litigation stay.”)).
