Reported but unconfirmed D.N.J. declaratory-judgment action by Acuitas against Arbutus and Genevant, challenging a list of patents including 11141378 and other Arbutus family patents. The narrative could not independently verify the case number 3:23-cv-04200 against the Acuitas caption.
Moderna Therapeutics filed an IPR against Arbutus's U.S. 8,058,069. The PTAB instituted review on July 24, 2019 and issued a Final Written Decision on July 23, 2020 holding Moderna failed to show claims 1–22 unpatentable under §103.
ModernaTX appealed the PTAB's IPR2019-00554 Final Written Decision on U.S. 8,058,069. The Federal Circuit docketed the appeal on Sept. 25, 2020, heard argument Oct. 7, 2021 (jointly with the companion '435 appeal, No. 20-1184), and affirmed on Dec. 1, 2021; mandate issued Jan. 10, 2022.
Acuitas filed a declaratory judgment action in S.D.N.Y. on March 18, 2022 against Genevant and Arbutus, seeking declarations that Comirnaty does not infringe and that nine Arbutus/Genevant patents, expressly including U.S. 8,058,069, are invalid. Acuitas voluntarily dismissed without prejudice on Aug. 4, 2023; the case terminated Aug. 7, 2023, and Acuitas refiled in D.N.J.
A 2026 Federal Circuit filing listed on the '069 patent's litigation tab. The narrative could not verify its parties, subject matter, or status; it may be tied to the Moderna settlement's reserved §1498 appeal or the consent judgment, but that is not confirmed.
