The following litigation involving US patent 11828425 is known:

  1. PTAB Inter Partes Review (IPR2024-01095)

    • Plaintiff(s): Samsung Display Co., Ltd. (Petitioner)
    • Defendant(s): Pictiva Displays International Ltd. (Patent Owner)
    • Jurisdiction: Patent Trial and Appeal Board (PTAB)
    • Case Number: IPR2024-01095
    • Filing Date: July 3, 2024
    • Outcome/Current Status: The PTAB issued a Final Written Decision on January 22, 2026 (corrected February 9, 2026), finding claims 2, 4, 9-12, and 17 of US patent 11828425 unpatentable as obvious. However, USPTO Director John Squires granted Director Review on June 25, 2026, and partially vacated the PTAB's decision, remanding the case for reconsideration of claim 2. This remand was due to the Board's failure to explain why its conclusion on claim 2 differed from a jury verdict in a parallel district court case. The status is currently "Pending Director Review".

    • Outcome/Current Status: Case No. 2:24-cv-00532 was consolidated with the earlier-filed Case No. 2:23-cv-00495 for all pretrial purposes on May 29, 2025, with 2:23-cv-00495 becoming the lead consolidated case.
