On Monday, April 9th, the Court of Appeals for the Federal Circuit upheld the invalidity of a series of patents asserted against the American subsidiary of Japanese consumer electronics firm Funai. The patents, owned by Illinois-based Maxon, LLC, covered electronic means for improving user control over subscription entertainment content but the claimed technologies were deemed to be invalid under 35 U.S.C. § 101, the basic statute governing the patentability of inventions. The decision was issued by a panel comprised of Chief Judge Sharon Prost and Circuit Judges Todd Hughes and Kara Stoll.
