On June 17, 2022, the USPTO issued a final rejection of all challenged claims at issue of U.S. Patent 10,244,252, owned by the Electronics and Telecommunications Research Institute (ETRI). This rejection comes less than a year after Unified filed the request for ex parte reexamination in October 2021. The ‘252 patent is part of the HEVC Advance Patent Pool, as well as SISVEL's AV1 patent pool. This reexamination was filed as part of Unified's ongoing efforts in its SEP Video Codec Zone.
