“We convene en banc to resolve whether, in light of the Supreme Court’s recent decision in Petrella v. Metro-Goldwyn-Mayer, Inc., 134 S. Ct. 1962 (2014), laches remains a defense to legal relief in a patent infringement suit.”
“We conclude that Congress codified a laches defense in 35 U.S.C. § 282(b)(1) that may bar legal remedies. Accordingly, we have no judicial authority to question the law’s propriety.”
