On March 10, 2022, InterDigital elected to withdraw the approval of their claims on both EP 1869893 B1 and EP 1872588 B1, bringing Unified’s opposition proceedings to an end. The EP ’893 and EP ’588 patents were part of a family purportedly essential to HEVC and part of the SISVEL AV1 patent pool. This filing is a part of Unified’s ongoing efforts in its SEP Video Codec Zone.

Unified is represented by Andrew McGettrick and Susan Keston from HGF Law, and by in-house counsel, Jessica L.A. Marks and Jung Hahm.
