Known litigation involving US patent 12256463 as of April 26, 2026:

  1. Inter Partes Review (IPR) Proceeding

    • Jurisdiction: Patent Trial and Appeal Board (PTAB)
    • Case Number: IPR2026-00112
    • Plaintiff(s)/Petitioner: Likely Meta Platforms, Inc. (based on related district court litigation and other IPRs in the same patent family), but not explicitly named in the provided snippets for this specific IPR.
    • Defendant(s)/Patent Owner: Sitnet LLC (as the current assignee of the patent and plaintiff in related district court litigation)
    • Filing Date: Not explicitly stated, but the case number IPR2026- indicates it was filed in 2026.
    • Outcome/Current Status: Pending.

  2. District Court Litigation

    • Jurisdiction: New York Southern District Court
    • Case Number: 1:25-cv-06185
    • Plaintiff(s): SitNet LLC
    • Defendant(s): Meta Platforms, Inc.
    • Filing Date: July 28, 2025
    • Outcome/Current Status: Active. This is a second complaint filed by SitNet LLC, asserting six patents from the same family, with infringement allegations targeting Facebook's Crisis Response feature and Ad platform. An earlier, related case (from July 2023) is reportedly stayed, awaiting final written decisions in IPRs concerning four patents from that complaint.

  3. Worldwide Family Litigation

    • Jurisdiction: Not specified.
    • Case Number: Not specified.
    • Plaintiff(s): Not specified.
    • Defendant(s): Not specified.
    • Filing Date: Not specified.
    • Outcome/Current Status: Litigation is ongoing for the patent family. Specific details require accessing the Darts-ip platform, which is beyond the scope of this response.

Note: Another case, "Castro v. Catholic Guardian Services (1:25-cv-06185)" in the New York Eastern District Court, was found with the same case number. However, based on the differing jurisdiction and parties, and the explicit linking of SitNet LLC v. Meta Platforms, Inc. to patent 12256463 (or its family) in multiple sources, the Castro case is not considered relevant to US patent 12256463 for this analysis.
