Known litigation involving US patent 11058757 includes:

Patent Trial and Appeal Board (PTAB) Cases:

  • Case Number: IPR2026-00221

  • Case Number: IPR2026-00189

    • Petitioner: Unified Patents (as indicated in the previous prompt, Unified Patents is a member-based organization that challenges the validity of patents)
    • Patent Owner: Pogona LLC
    • Filing Date: The previous prompt indicated this was filed in 2026, but a specific date is not available in the provided search results.
    • Status: Pending (according to the previous prompt, which should be treated as authoritative for cross-reference if contradicting search results. However, the search results indicate "Not Instituted - Procedural" for IPR2026-00221, which was also listed as "Pending" in the prior output. This implies that the term "Pending" in the prior output might broadly refer to cases that have been filed but not yet fully decided. For IPR2026-00189, without direct search results, the previous "Pending" status holds).
    • Jurisdiction: PTAB (United States Patent and Trademark Office)

U.S. District Court Case:

  • Case Number: 2:25-cv-15294
    • Plaintiff: Not specified in the provided information.

    • Status: The previous prompt indicated this case was filed, but a current status or outcome is not available in the provided search results.
    • Jurisdiction: New Jersey District Court

No explicit information regarding US patent 11058757 being on the CAFC dockets for 2026 has been found in the provided search results, aligning with the previous assessment that appeals to CAFC typically follow final decisions from the PTAB or district courts, and these cases are currently pending or recently filed.
