PTAB challenges
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 May 20, 2026, a search of the USPTO Open Data Portal and publicly available records indicates that there are no AIA trial proceedings (such as Inter Partes Reviews, Post-Grant Reviews, or Covered Business Method reviews) on file for US Patent 11937145. This means the patent's claims remain untested by the PTAB, offering a different defensive posture than one that has survived or been invalidated by PTAB challenges.
Strategic summary
Currently, all nine claims of US11937145 remain UNTESTED by the PTAB. There are no PTAB decisions that have either canceled or sustained any claims. Therefore, there is no estoppel landscape established by prior AIA trials under 35 U.S.C. § 315(e)(2), which would typically bar petitioners and their privies from raising grounds that were raised or reasonably could have been raised. This means all prior art grounds remain available for a potential future PTAB challenge.
The absence of PTAB activity for a patent, especially one that is currently involved in district court litigation (as indicated in the patent summary), can be a signal. It suggests that potential challengers may not have pursued this avenue, or that any challenges have not yet become public.
Recommended next steps
Given the absence of PTAB activity on US11937145, a defendant currently facing assertion of this patent should consider the following:
- Conduct a thorough prior art search: Since no claims have been tested, all prior art grounds (e.g., under § 102 or § 103) are available for a potential IPR or other AIA trial. This search should specifically look for art not previously considered by the USPTO during prosecution.
- Evaluate for PTAB challenge: If strong prior art is found, consider filing an IPR petition. This would be a first PTAB challenge for this patent, and the claims would be evaluated on their merits without prior PTAB decisions to consider.
- Monitor for future filings: Keep an eye on the PTAB's docket for US11937145, as well as any related patents in the family, for new petitions that may be filed by other parties.
As there are no active or concluded PTAB proceedings, there are no specific FWDs or institution decisions to link to at this time.

The patent family associated with US11937145 B2 is currently active and has a "Family has litigation" status, with multiple cases filed in the Texas Eastern District Court. Despite this district court activity, no corresponding PTAB challenges have been publicly filed against US11937145. For instance, in a case involving Nearby Systems LLC (the patent owner) and Cinemark USA concerning location technology patents, the dispute ended in a settlement on March 1, 2024, without any inter partes review petitions being filed. Similarly, a patent infringement action by Nearby Systems LLC against Little Caesar Enterprises concluded on February 19, 2026, also without a substantive ruling on patent validity or infringement, and no IPRs were explicitly noted. This pattern suggests that defendants in these cases may have assessed negotiated settlements as more economically rational than pursuing a multi-front PTAB challenge in addition to district court litigation.
