On October 14, 2026, Unified Patents filed an ex parte reexamination proceeding against U.S. Patent 11,677,940, owned by Intellectual Discovery Co., Ltd., an NPE. The ‘940 patent covers a method for efficiently dividing video frames into smaller blocks for compression by using a Multi-Type-Tree (MTT) framework (quad-tree, binary-tree, and ternary-tree) with specific rules governing corner boundary splits as its alleged point of novelty. The ‘940 patent was identified as essential to Access Advance's VVC/H.266 pool and this filing is a part of Unified’s Video Codec SEP Zone.
Unified is represented by in-house counsel, Andrea Shoffstall and Jessica L.A. Marks, in this proceeding.
