On March 7, 2025, one month after Unified filed an ex parte reexamination, the Central Reexamination Unit (CRU) granted Unified’s request, finding substantial new questions of patentability on all challenged claims of U.S. Patent 10,904,539, owned by Ideahub Inc., an NPE. The ‘539 patent relates to video coding techniques that apply linear method (LM) prediction modes and particularly to the prediction of a chroma pixel value using a LM chroma mode or a low-pass-filtered LM chroma mode. It has been designated as essential to the VVC standard in the Access Advance’s VVC patent pool.

Unified is represented by Dagim Tilahun and Jon Bowser of Haynes and Boone, and by in-house counsel, Jessica L.A. Marks and Michelle Aspen, in this proceeding.
