On November 21, 2016, the Federal Circuit reversed a CBM institution decision made by the PTAB in Unwired Planet, LLC. v. Google Inc., criticizing that the PTAB's defiintion of a CBM patent was overly broad. This case originated when Unwired Planet enforced U.S. Patent No. 7203752 (the '752 patent) against Google, which related to methods and systems for managing location information for wireless devices. In defense, Google concurrently petitioned the PTAB to institute both an IPR proceeding as well as a CBM proceeding in December, 2013, challenging the validity of the '752 patent.
