9138862

Samsung Austin Semiconductor and other Samsung entities petitioned for inter partes review of U.S. 9,138,862. The PTAB instituted review and issued a Final Written Decision on September 17, 2025 holding the challenged claims unpatentable. The proceeding was appealed.

Appeal from PTAB IPR2024-00534 concerning U.S. 9,138,862. The record indicates the appeal was resolved by dismissal pursuant to settlement, but the narrative did not independently verify the 26-1528 order.

Chien-Min Sung sued Kinik Company in D. Del. The Delaware action asserted U.S. 9,724,802, not the '862 patent. The '862 appears as a parent/family patent in the related dispute; the case was closed.
