On November 6, 2018, the Court of Appeals for the Federal Circuit (CAFC) issued an opinion affirming a final written decision by the Patent Trial and Appeal Board (PTAB) finding the patent claims that had been challenged by inter partes review (IPR) to be not unpatentable.   Acceleration Bay, LLC v. Activision Blizzard Inc., —F.3d—, (Fed. Cir. November 6, 2018).  The CAFC ruled that the patent challenger had not proved that an article available on the Internet before the critical date was a “printed publication,” and that the article therefore was not available as prior art.
