USPTO Director Kathi Vidal recently vacated a PTAB decision denying institution of a post-grant review and remanded the case for further proceedings. The petitioner challenged claims 1–27 of the ’274 patent under 35 U.S.C. § 112(a) for lacking written description and enablement, and under 35 U.S.C. § 103 as obvious in view of prior art. The Board denied institution, exercising its discretion under 35 U.S.C. § 325(d).
