On May 26, 2015, in a 6-2 Opinion written by Justice Anthony Kennedy in Commil USA v. Cisco Systems, 13-896, the Supreme Court ruled that a defendant’s good faith believe that a patent is invalid is not a defense to a claim of induced infringement. The decision vacated a $74 million verdict against Cisco Systems and overturned a Federal Circuit split panel decision that held “evidence of an accused inducer’s good-faith belief of invalidity may negate the requisite intent for induced infringement. A divided Federal Circuit denied an en banc rehearing of the split panel decision. The Supreme Court held that “the issue of infringement and validity appear in separate parts of the Patent Act. . . . Were this Court to interpret §271(b) as permitting a defense of belief in invalidity, it would inflate the issues of infringement and validity.” Justice Scalia, joined by Chief Justice Roberts, dissented on this issue.
