PTAB challenges

Given that the "PTAB proceedings on file" states no AIA trial proceedings were found via the USPTO ODP API, and my initial web search did not immediately surface any specific PTAB cases for US7482916 (the search results provide general information about IPR, PGR, and CBM processes), I will conclude that there are no active or concluded PTAB proceedings for this patent based on the current available information. I need to explicitly state this.## Proceedings Overview

As of May 22, 2026, there are no active or concluded AIA trial proceedings (Inter Partes Review, Post-Grant Review, or Covered Business Method review) on file for US Patent 7,482,916. The USPTO Open Data Portal API indicates no such proceedings, and a targeted web search for PTAB activity did not surface any records. This means the patent's claims have not been challenged or adjudicated before the Patent Trial and Appeal Board.

Strategic Summary

All claims of US Patent 7,482,916 remain untested by AIA trial proceedings. This means no claims have been canceled, sustained, or narrowed through the PTAB process. The patent owner, Wyoming Technology Licensing, LLC, has not faced a PTAB challenge on this patent.

The absence of PTAB activity implies that potential petitioners have either not found strong enough prior art to warrant a challenge, or have opted for other strategies (e.g., district court litigation, settlement). Since no PTAB proceedings have occurred, there is no estoppel landscape under 35 U.S.C. § 315(e)(2) for this patent. This means a defendant currently facing assertion of this patent is not barred from raising any prior-art grounds that could have been raised in an IPR or PGR. Any relevant prior art, including that cited during prosecution (U.S. Pat. Nos. 5,712,618, 6,226,389 B1, 6,321,159 B1, and 3,771,096), remains fully available for use in district court or future PTAB petitions.

The patent expired on January 28, 2025, meaning any ongoing litigation would be for past infringement only. The current litigation against General Motors LLC and Toyota Motor North America, Inc. would therefore pertain to alleged infringement that occurred before the patent's expiration.

Recommended Next Steps

Since there are no PTAB proceedings on file for US7482916, there are no specific trial-stage milestones to track. For a defendant currently being asserted against:

• Review all claims for validity challenges: Given the absence of PTAB challenges, a thorough invalidity analysis, including a fresh prior art search, would be highly recommended. The prior art cited during prosecution (U.S. Pat. Nos. 5,712,618, 6,226,389 B1, 6,321,159 B1, and 3,771,096) should be meticulously re-evaluated for its applicability to all asserted claims.
• Consider the expired status: As the patent expired on January 28, 2025, any potential liability is limited to damages for past infringement. This significantly alters the risk profile compared to an active patent.
• Focus on claim construction and non-infringement: Without PTAB precedent on claim validity, claim construction in district court will be a critical battleground. Strong non-infringement arguments based on careful claim construction should be developed.
• Evaluate the continuation patents: While the parent patent 7482916 has expired, its continuation patents (e.g., US 7,986,223, US 8,378,805, etc.) are still active and may be asserted. Any defensive strategy should extend to these related patents.
