8472936

Apple Inc. challenged the patentability of US8472936 before the PTAB. The PTAB issued a Final Written Decision, which was appealed. The Federal Circuit later reversed in part, vacated in part, and remanded, concluding the Board was precluded from finding certain claims of US8472936 patentable due to issue preclusion with claims from related patents 8761739 and 8442501 previously found unpatentable in other IPRs.

Smart Mobile Technologies LLC sued Apple Inc. for patent infringement. The court granted Apple's motion to transfer venue, and the case was subsequently transferred to the U.S. District Court for the Northern District of California.

Samsung appealed to the Federal Circuit, likely from a PTAB IPR proceeding involving Smart Mobile Technologies LLC. Samsung voluntarily dismissed the appeal on August 6, 2024.
