Commil USA, LLC v. Cisco Systems, Inc., 135 S.Ct. 1920 (2015), was a 2015 decision by the United States Supreme Court pertaining to the standard for induced patent infringement. Writing for a 6-2 majority, Justice Anthony Kennedy held that (1) a claim of induced infringement requires a showing that the defendant knew that it is engaging in infringing conduct and (2) a defendant's belief that a patent is invalid is not a defense to a claim of induced infringement. Justice Antonin Scalia dissented from the second point, arguing that, in his view, a good faith belief in a patent's invalidity should constitute a defense to a charge of induced infringement.
