“The notion that G+ had no notice of the ‘may’ language or the arguments surrounding it is one that we squarely reject.” – Federal CircuitThe U.S. Court of Appeals for the Federal Circuit (CAFC) on Thursday affirmed a Patent Trial and Appeal Board (PTAB) ruling for Samsung Electronics, finding the Board did not violate the Administrative Procedures Act (APA) and that substantial evidence supported its findings. Samsung filed for inter partes review (IPR) of claims 1–5, 7–9, 14, and 20 of G+ Communications’ U.S. Patent No. 10,736,130, which is titled “Method and device for uplink control signal transmission, user terminal, and storage medium.” G+ also questioned whether substantial evidence supports the Board’s finding that Kwak discloses limitation 1d of the ’130 patent, but the CAFC accepted the Board’s reliance on Samsung’s expert’s testimony as substantial evidence of anticipation, and ultimately affirmed.
