Proceedings overview
The USPTO ODP API returns no AIA trial proceedings for this patent as of the most recent ingest. Web search did not surface any additional PTAB activity. Therefore, there are no PTAB proceedings on file for U.S. Patent 12,406,663, and all claims are currently untested in an AIA trial. This means a defendant would need to pursue an initial PTAB challenge if they wished to invalidate the claims through this venue.
Strategic summary
All claims of U.S. Patent 12,406,663 are currently untested in PTAB proceedings. No claims have been canceled or sustained through an AIA trial. Consequently, there is no estoppel landscape to consider under § 315(e)(2), and all prior-art grounds are still available for potential challenges. The absence of PTAB activity could indicate that the patent has not yet been aggressively asserted in a manner that would typically trigger such challenges, or it is too new to have garnered such attention.
Recommended next steps
As there is no PTAB activity on file, a defendant facing assertion of U.S. Patent 12,406,663 would need to initiate a new AIA trial (e.g., an Inter Partes Review or Post-Grant Review) if they wish to challenge the patentability of its claims before the PTAB.
