The Patent Trial and Appeal Board denied a petition to institute inter partes review, finding there was no reasonable likelihood that petitioners would prevail on their obviousness challenges. In rendering its decision, the PTAB rejected petitioners’ proposed claim construction as being contrary to plain meaning and being improperly grounded in irrelevant embodiments. The PTAB also declined to rely on statements concerning a device depicted in a video because those statements fell outside the ambit of prior art under 35 U.S.C. § 311(b). Finally, while the majority opinion declined to address the issue of whether the video itself was a printed publication, one judge found, in concurrence, that a publicly accessible video can qualify as a printed publication under the statute. More details regarding those rulings are provided below.
