As of May 4, 2026, U.S. Patent No. 10,664,518 has been involved in significant litigation, including a district court case that was appealed to the U.S. Court of Appeals for the Federal Circuit, and a proceeding before the Patent Trial and Appeal Board.

District Court and Federal Circuit Litigation

  • Case Name: NantWorks, LLC et al. v. Niantic, Inc.
  • Plaintiff(s): NantWorks, LLC, and Nant Holdings IP, LLC.
  • Defendant(s): Niantic, Inc.
  • Jurisdiction: U.S. District Court for the Northern District of California.
  • Case Number: 3:20-cv-06262.
  • Filing Date: September 3, 2020.
  • Status/Outcome:
    • District Court: On January 13, 2023, the court granted summary judgment in favor of Niantic, Inc., ruling that the claims of U.S. Patent 10,664,518 were invalid. The court found the claims were directed to the abstract idea of providing information based on a location on a map and therefore were not patent-eligible under 35 U.S.C. § 101. The case involved Niantic's popular augmented reality games, such as Pokémon Go and Harry Potter: Wizards Unite.
    • Court of Appeals: NantWorks appealed the decision to the U.S. Court of Appeals for the Federal Circuit (Case No. 24-2216). On April 23, 2026, the Federal Circuit affirmed the district court's decision in a non-precedential opinion. The appellate court agreed that the patent claims were directed to an abstract idea and lacked a sufficient inventive concept.

Patent Trial and Appeal Board (PTAB) Proceeding

  • Case Name: Niantic, Inc. v. Nant Holdings IP, LLC, and NantWorks, LLC
  • Petitioner: Niantic, Inc.
  • Patent Owner: Nant Holdings IP, LLC, and NantWorks, LLC.
  • Jurisdiction: U.S. Patent and Trademark Office, Patent Trial and Appeal Board (PTAB).
  • Case Number: IPR2021-01119.
  • Filing Date: The petition for Inter Partes Review (IPR) was filed by Niantic, Inc. to challenge the validity of the patent claims.
  • Status/Outcome: The PTAB ultimately did not institute a trial on the merits for this IPR petition. This proceeding ran concurrently with the district court litigation.
