PART II. OTHER INFORMATION
ITEM 1. LEGAL PROCEEDINGS
Except as discussed below, there are no material changes from the legal proceedings previously disclosed in our 2024 Annual Report during the three and nine months ended September 30, 2025.
On June 14, 2022, the Company received a paragraph IV notice of certification (the “Fresenius Kabi Notice”) from Fresenius Kabi advising that Fresenius Kabi had submitted an ANDA to the FDA seeking approval to manufacture, use or sell a generic version of CINVANTI in the U.S. prior to the expiration of U.S. Patent Nos.: 9,561,229; 9,808,465; 9,974,742; 9,974,793; 9,974,794; 10,500,208; 10,624,850; 10,953,018; and 11,173,118 (the “CINVANTI Patents”), which are listed in the FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations (the “Orange Book”). The Fresenius Kabi Notice alleges that the CINVANTI Patents are invalid, unenforceable and/or will not be infringed by the commercial manufacture, use or sale of the generic product described in Fresenius Kabi’s ANDA.
On July 27, 2022, the Company filed a complaint for patent infringement of the CINVANTI Patents against Fresenius Kabi and a related entity in the U.S. District Court for the District of Delaware (the “Court”) in response to Fresenius Kabi’s ANDA filing. The complaint seeks, among other relief, equitable relief enjoining Fresenius Kabi from infringing the CINVANTI Patents. On May 15, 2024, the Court granted partial summary judgment of infringement for the Company and found no indefiniteness of U.S. Patent Nos. 9,561,229 and 9,974,794. On June 24, 2024, the parties commenced a four-day bench trial centered on Fresenius Kabi’s defense of obviousness of claims from U.S. Patent Nos. 9,561,229 and 9,974,794 that cover CINVANTI. Oral argument was held on August 29, 2024.
On December 3, 2024, the Court issued a ruling in the Company’s favor. The Court found that the Company’s U.S. Patent Nos. 9,561,229 and 9,974,794, which expire in 2035, are valid and would be infringed by Fresenius Kabi’s proposed generic product. In view of the decision, the Court ordered that the effective date of any final approval by the U.S. Food and Drug Administration of Fresenius Kabi’s ANDA shall not be a date earlier than September 18, 2035, the expiration date of each of U.S. Patents Nos. 9,561,229 and 9,974,794. On January 8, 2025, Fresenius Kabi filed notice of appeal to the U.S. Court of Appeals for the Federal Circuit (“Federal Circuit”). On September 24, 2025, the briefing was completed, and the Company awaits a date for oral argument. The Company intends to vigorously enforce its intellectual property rights relating to CINVANTI.
On August 4, 2023, the Company received a Notice Letter (the “Mylan August Notice”) from Mylan Pharmaceuticals Inc. (“Mylan”) advising that Mylan had submitted an abbreviated new drug application ("ANDA") to the FDA seeking approval to manufacture, use or sell a generic version of CINVANTI (“Mylan’s ANDA for a generic version of CINVANTI”) in the U.S. prior to the expiration of U.S. Patent Nos. 9,561,229; 9,808,465; 9,974,742; 9,974,793; 9,974,794; 10,500,208; 10,624,850; 10,953,018; and 11,173,118 (the “CINVANTI Patents”), which are listed in the Orange Book. The Mylan August Notice alleges that the CINVANTI Patents are invalid, unenforceable and/or will not be infringed by the commercial manufacture, use or sale of the generic product described in Mylan’s ANDA for a generic version of CINVANTI. On September 15, 2023, the Company filed a complaint for patent infringement of the CINVANTI Patents against Mylan in the U.S. District Court for the District of Delaware in response to the filing of Mylan’s ANDA for a generic version of CINVANTI. The complaint seeks, among other relief, equitable relief enjoining Mylan from infringing the CINVANTI Patents. On November 9, 2023, the Company received an updated Notice Letter from Mylan advising that it had submitted an amendment to Mylan’s ANDA for a generic version of CINVANTI to include a Paragraph IV certification to the Company's recently listed U.S. Patent No. 11,744,800. On May 6, 2025, the Company announced that it entered into a settlement agreement with Mylan to resolve the ongoing patent litigation in the U.S. District Court for the District of Delaware related to Mylan’s ANDA for a generic version of CINVANTI. Pursuant to the terms of the settlement agreement, the Company has granted Mylan a license under the Orange Book-listed patents for CINVANTI to market a generic version of CINVANTI in the United States beginning June 1, 2032, or earlier under certain customary circumstances. In connection with the settlement, on May 6, 2025, the Court granted the Stipulation and Order of Dismissal with the U.S. District Court for the District of Delaware requesting that the Court dismiss the pending litigation between the parties.
On December 16, 2023, the Company received a Notice Letter (the “Mylan December Notice”) from Mylan advising that Mylan had submitted an ANDA to the FDA seeking approval to manufacture, use or sell a generic version of APONVIE in the U.S. (“Mylan’s ANDA for a generic version of APONVIE”) prior to the expiration of U.S. Patent Nos.: 9,561,229; 9,808,465; 9,974,742; 9,974,793; 9,974,794; 10,500,208; 10,624,850; 10,953,018; 11,173,118; and 11,744,800 (the “APONVIE Patents”), which are listed
