PTAB Inter Partes Review (IPR):

  • American Airlines, Inc. et al. v. Intellectual Ventures I LLC
    • Case Number: IPR2025-00785
    • Filing Date: Before April 10, 2025 (as Director's decision mentions it was filed by that date).
    • Status: Not Instituted - Merits. The Director's decision, dated August 29, 2025, declined discretionary denial of institution, citing factors such as the age of the challenged patents (14-18 years, creating settled expectations), an existing ex parte reexamination request for one of the patents, and the large number and wide scope of patents asserted in parallel district court litigation. The projected final written decision due date in these proceedings is November 9, 2026. The PTAB decision was "Not Instituted - Merits" as per Google Patents, but the Director's decision indicates discretionary denial was not appropriate. This suggests a more nuanced outcome where the IPR was not instituted for reasons other than discretionary denial based on the merits of the arguments presented. The Google Patents information stating "Not Instituted - Merits" is acknowledged.

Ex Parte Reexamination:

  • Unified Patents filed an ex parte reexamination proceeding against U.S. Patent 7,257,582 on June 19, 2025. This reexamination is currently before the USPTO.
