As a patent attorney on May 8, 2026, I have reviewed the litigation history for U.S. Patent No. 11,991,234 B2.

Contrary to the information in the previously generated "Patent summary," which stated that a search of CAFC dockets yielded no results, the authoritative patent text provided for this analysis explicitly lists several legal proceedings. The following is a detailed summary of known litigation involving this specific patent, based on the provided patent documentation and further research.

Patent Trial and Appeal Board (PTAB) Proceedings

1. IPR2024-00940

  • Petitioner: Aylo Freesites Ltd.
  • Patent Owner: DISH Technologies LLC
  • Jurisdiction: USPTO Patent Trial and Appeal Board
  • Case Number: IPR2024-00940
  • Filing Date: I am unable to confirm the specific filing date with high confidence.
  • Outcome/Status: The authoritative patent text indicates a "Final Written Decision" was reached. On February 3, 2026, a decision was made to vacate the Final Written Decision and terminate the proceeding. This occurred because the petitioner had to add a real party in interest, which resulted in the petition being accorded a new, later filing date, rendering it time-barred under 35 U.S.C. § 315(b).

2. IPR2024-00941

  • Petitioner: I am unable to confirm the petitioner with high confidence.
  • Patent Owner: DISH Technologies LLC
  • Jurisdiction: USPTO Patent Trial and Appeal Board
  • Case Number: IPR2024-00941
  • Filing Date: I am unable to confirm the specific filing date with high confidence.
  • Outcome/Status: The authoritative patent text describes the status as "Not Instituted - Procedural." This indicates the PTAB declined to initiate an Inter Partes Review on procedural grounds.
