CAFC Affirms PTAB Obviousness Finding in Sony IPR Remand

CAFC affirmed PTAB's obviousness finding invalidating claims 1-12 of Intellectual Pixels Limited's U.S. Patent 10,681,109 in IPR proceedings brought by Sony Interactive Entertainment. The patent covered digital image generation using external visual servers. On remand from earlier Federal Circuit appeal, PTAB found claims obvious over prior art references Wiltshire and Saha. CAFC rejected IPL's arguments that PTAB exceeded its mandate and lacked substantial evidence, emphasizing that courts review judgments, not opinions.
