US Patent 10237577 has been involved in the following litigation:

Case 1: Inter Partes Review (IPR) and Subsequent Appeals

  • Plaintiff(s): Unified Patents, LLC (Petitioner in IPR), Dolby Laboratories Licensing Corp. (Patent Owner in IPR, Appellant in CAFC, Petitioner in Supreme Court)
  • Defendant(s): Dolby Laboratories Licensing Corp. (Patent Owner in IPR), Unified Patents, LLC (Appellee in CAFC, Respondent in Supreme Court)
  • Jurisdiction: Patent Trial and Appeal Board (PTAB), U.S. Court of Appeals for the Federal Circuit (CAFC), Supreme Court of the United States
  • Case Number:
    • IPR: IPR2021-00275 (though the provided text references IPR2021-00275, the Google Patents page for US10237577 also lists IPR2021-00275 filed (Final Written Decision), linking to the Unified Patents portal, so this confirms the IPR number.)
    • CAFC: 23-2110
    • Supreme Court: No. 25A713 (extension of time to file petition) (The provided text from the Supreme Court petition refers to a case number for the petition for certiorari itself, not a final Supreme Court case number yet, as the petition was just filed.)
  • Filing Date:
    • IPR Petition: December 11, 2020
    • CAFC Appeal: July 6, 2023
    • Supreme Court Petition: Time extended to February 20, 2026
  • Outcome/Current Status:
    • PTAB (IPR2021-00275): The Patent Trial and Appeal Board (PTAB) issued a final written decision finding that Unified Patents failed to show any of the challenged claims (claims 1, 7, and 8) of US10237577 were unpatentable. The Board also declined to adjudicate Dolby's arguments regarding other real parties in interest.
    • CAFC (Case No. 23-2110): Dolby Laboratories Licensing Corp. appealed the PTAB's decision. The Federal Circuit dismissed the appeal on June 5, 2025, on procedural grounds due to Dolby failing to establish an injury in fact sufficient to confer standing to appeal. No ruling was issued on the substantive patentability questions.
    • Supreme Court: Dolby Laboratories Licensing Corp. filed a petition for certiorari to the Supreme Court by February 20, 2026, challenging the Federal Circuit's conclusions regarding a patent owner's right to know all real parties in interest and whether 35 U.S.C. § 314(d) bars judicial review of final decisions regarding real parties in interest. The current status is that the petition for certiorari has been filed.
