MTD Products Inc. v. Andrei Ianchu, Under Secretary of Commerce for Intellectual Property and Director of the United States Patent and Trademark Office
Fed. Cir. August 12, 2019 Before Circuit Judges Reyna, Taranto, and Stoll
The Toro Company sought inter partes review before the Patent Trial and Appeal Board. The Board held the challenged claims obvious under 35 U.S.C. § 103.
