On February 10, 2023, the United States Court of Appeals for the Federal Circuit summarily affirmed the PTAB’s ruling that all challenged claims of U.S. Patent 9,641,849 are unpatentable. Owned by Ideahub Inc., the IPR was filed as part of Unified's ongoing efforts in its SEP Video Codec Zone. The '849 patent relates to a video compression technique known as intra prediction and Access Advance claims that certain claims of the '849 patent were essential to the HEVC standard.

This appeal comes from a Final Written Decision (IPR2020-00702) invalidating U.S. Patent 9,641,849 and denying a motion to amend the claims based on a lack of written description support. The decision is a nonprecedential written opinion.

Unified was represented by Angela Oliver, Raghav Bajaj, David McCombs, Jon Bowser, and Debbie McComas from Haynes and Boone, and by in-house counsel, Roshan Mansinghani, Ashraf Fawzy, and Michelle Aspen, in these proceedings.
