The United States Court of Appeals for the Federal Circuit reviewed an appeal from the Patent Trial and Appeal Board’s decision in an ex parte reexamination of U.S. Patent No. 7,933,431, owned by Gesture Technology Partners, LLC. The decision interpreted provisions of 35 U.S.C. § 315(e)(1), affirmed the PTAB’s decision to invalidate two claims in Gesture’s patent on motion-sensing technology, and confirmed the Board’s authority to rule on expired patents.
