Post-Grant Proceeding (Inter Partes Review)
In response to the district court litigation, a petition was filed to challenge the validity of the patent's claims before the U.S. Patent and Trademark Office's Patent Trial and Appeal Board (PTAB).
- Petitioner: Toyota Motor Corporation
- Patent Owner: Bunker Hill Technologies, LLC
- Jurisdiction: Patent Trial and Appeal Board (PTAB)
- Case Number: IPR2026-00334
- Filing Date: April 7, 2026
- Status: The proceeding is in its initial phase and is currently "Pending Institution Decision." This means the PTAB is reviewing the petition and will decide whether to formally institute a trial to review the patentability of the claims challenged by Toyota.
