Strategic summary
As of today, May 29, 2026, all claims of US Patent 11,336,597 remain untested by Inter Partes Review (IPR), Post-Grant Review (PGR), or Covered Business Method (CBM) proceedings at the Patent Trial and Appeal Board (PTAB). This means the patent has not been challenged through these administrative processes, and no claims have been canceled or narrowed by the PTAB.
The absence of PTAB activity suggests that any prior art grounds that could have been raised in an IPR, PGR, or CBM are still available for a defendant currently facing assertion of this patent. There are no estoppel implications under § 315(e)(2) for any potential petitioner or their privies regarding this patent.
Recommended next steps
Since no PTAB activity exists for US Patent 11,336,597, a defendant currently facing assertion of this patent would have all avenues for challenging the patent at the PTAB open to them. The absence of PTAB challenges for a patent that has been in litigation since at least mid-2022 is notable and could indicate that potential petitioners have not found sufficiently strong grounds for IPR/PGR or have chosen to settle rather than pursue PTAB trials. A thorough prior art search would be a crucial first step to evaluate the viability of an IPR or PGR petition.
