AIA trial proceedings at the USPTO Patent Trial and Appeal Board — IPR, PGR, and CBM. Petitioners, judge panels, claim-level invalidation outcomes from Final Written Decisions, and Federal Circuit appeals. The single most important defensive datapoint after litigation history.
Proceedings overview
As of July 3, 2026, there are no AIA trial proceedings on file for US Patent 12359958. This means that all claims of the patent remain untested at the PTAB, and no claims have been invalidated or sustained through an AIA trial.
Strategic summary
Given that there are no PTAB proceedings on file for US Patent 12359958, all 18 claims (Claims 1-10, 15-18 for apparatus and Claims 11-14 for method) remain legally valid and untested by this specific administrative body. This means a defendant facing assertion of this patent would find that no claims have been canceled or narrowed through IPR, PGR, or CBM trials.
The estoppel landscape is currently moot, as no PTAB trials have occurred. Therefore, the statutory estoppel provisions of 35 U.S.C. § 315(e)(2) (for IPRs) or § 325(e)(2) (for PGRs) do not apply to any potential petitioner. All prior art grounds are theoretically still available for a new PTAB challenge, should a defendant choose to pursue one. The absence of PTAB activity also suggests that the patent has not yet faced significant challenges in this forum, either because it has not been widely asserted, or because potential challengers have opted for other strategies or found no compelling grounds for an AIA trial.
Recommended next steps
Since no PTAB activity exists for US Patent 12359958, a defendant facing assertion of this patent should be aware that all claims are presumed valid and have not been subjected to PTAB scrutiny. The absence of PTAB proceedings suggests that the patent may not have been heavily litigated or challenged in this specific forum.
If considering an AIA trial, potential petitioners would need to:
- Conduct a thorough prior art search to identify grounds for challenging the patentability of claims under 35 U.S.C. §§ 102 or 103 (for IPR) or additional grounds under § 112 (for PGR).
- File a petition for an IPR or PGR, meeting all statutory and regulatory requirements, including the threshold for institution.
The absence of PTAB activity indicates that this particular avenue of challenge remains open, without the constraints of prior estoppel.
