PTAB challenges

Proceedings overview

There are no AIA trial proceedings on file for US Patent 10681946. This means the patent has not been challenged through Inter Partes Review (IPR), Post-Grant Review (PGR), or Covered Business Method (CBM) proceedings at the Patent Trial and Appeal Board (PTAB). Therefore, for a defendant, the patent claims remain as granted, and there is no record of claims being invalidated or sustained by the PTAB.

Strategic summary

As of the current date, US Patent 10681946 has no PTAB proceedings on record. All claims (1-20) of the patent remain untested by AIA trial procedures. This means there are no claims that have been canceled or sustained by the PTAB. Consequently, there is no estoppel landscape established under § 315(e)(2) for this patent. The absence of PTAB challenges could indicate that potential challengers have not yet found sufficient prior art to meet the institution threshold, or that the patent has not been asserted aggressively enough to provoke such challenges. There is no evidence of any pattern of PTAB filings by a specific petitioner or any involvement of defensive aggregators.

Recommended next steps

Since no PTAB activity exists for US Patent 10681946, the first step for a defendant facing assertion of this patent would be to conduct a thorough prior art search to determine if strong invalidity arguments exist. If such art is found, initiating an Inter Partes Review (IPR) at the PTAB could be a viable defense strategy. The absence of prior PTAB challenges means that a petitioner would have a clear field to present their best prior art arguments without being constrained by estoppel from previous proceedings.The USPTO Open Data Portal (ODP) API indicates no AIA trial proceedings on file for US Patent 10681946 as of the most recent ingest. A web search for PTAB proceedings related to US10681946 also did not return any active or concluded Inter Partes Review (IPR), Post-Grant Review (PGR), or Covered Business Method (CBM) proceedings.

Proceedings overview

There are no AIA trial proceedings on file for US Patent 10681946. This means all claims of the patent remain as originally granted and have not been subject to review or modification by the PTAB. This gives a defendant no immediate PTAB-related leverage, as no claims have been invalidated or sustained in such proceedings.

Strategic summary

As of the current date (2026-05-30), US Patent 10681946 has no PTAB proceedings on record. All twenty claims (1-20) of the patent remain untested by AIA trial procedures such as IPR, PGR, or CBM. Consequently, no claims have been canceled or confirmed patentable by the PTAB. The absence of such proceedings also means there is no estoppel landscape established under 35 U.S.C. § 315(e)(2), which would bar petitioners (and their privies) from raising grounds that were raised or reasonably could have been raised. Therefore, all prior-art grounds remain available for potential challengers. There is no visible pattern of PTAB filings by a specific petitioner, nor any indication of aggressive PTAB appeals by the patent owner or involvement of defensive aggregators.

Recommended next steps

Given the absence of any PTAB activity, a defendant currently facing assertion of US Patent 10681946 should undertake a comprehensive prior art search. If strong prior art is discovered that anticipates or renders obvious the claimed invention, filing a petition for Inter Partes Review (IPR) at the PTAB could be a strategic and effective defense. The lack of previous challenges means that a well-supported IPR petition would be the first opportunity for the PTAB to consider the patentability of the claims based on prior art.
