As a patent attorney, I can report the following known litigation involving U.S. Patent No. 11,589,142 based on currently available information.

There are two primary legal actions identified involving this patent: a district court patent infringement lawsuit and an Inter Partes Review (IPR) proceeding before the Patent Trial and Appeal Board (PTAB).

  • Jurisdiction: U.S. District Court for the Central District of California.
  • Case Number: 2:24-cv-06703.
  • Filing Date: August 7, 2024.
  • Status: The case appears to be in its early stages.

Patent Trial and Appeal Board (PTAB) Proceeding

  • Inter Partes Review (IPR)
  • Petitioner: Nokia Of America Corp.
  • Patent Owner: Spada Innovations Inc.
  • Jurisdiction: USPTO Patent Trial and Appeal Board.
  • Case Number: IPR2025-01442.
  • Filing Date: August 27, 2025.
  • Status: The PTAB has not instituted a trial on the merits. A decision on whether to institute the IPR was made on February 24, 2026.

These matters indicate that U.S. Patent No. 11,589,142 is being actively asserted and challenged. SPADA Innovations, Inc. is the current owner of the patent and is enforcing it against AT&T in federal court. Concurrently, Nokia is challenging the validity of the patent's claims before the USPTO.
