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.
Arbutus and Genevant asserted five LNP patents, including the '359 patent, against Pfizer and BioNTech over Comirnaty. The action remains pending after a September 2025 claim construction ruling and was carved out of the Moderna settlement.
Acuitas filed a declaratory-judgment action in S.D.N.Y. seeking declarations that Comirnaty does not infringe and nine Arbutus/Genevant patents are invalid; the '320 patent was identified in a June 3, 2022 notice. After a motion to dismiss, Acuitas amended and then voluntarily dismissed the action and refiled in D.N.J.
