Strategic summary
As of May 30, 2026, all claims (1-10) of US Patent 11,346,627 remain untested by any AIA trial proceeding. This means the patent owner has not yet had to defend the patentability of its claims before the PTAB.
Since there are no PTAB proceedings, there is no estoppel landscape to consider under 35 U.S.C. § 315(e)(2). All prior-art grounds remain available for a defendant to assert. There is no pattern of PTAB filings by any petitioner, nor has the patent owner been involved in any PTAB appeals for this patent. The absence of PTAB challenges for a patent that was granted in May 2022 could indicate a variety of factors, such as the patent not being widely asserted or its claims not being perceived as vulnerable to invalidation through AIA trials.
Recommended next steps
If you are a defendant facing assertion of US Patent 11,346,627, the absence of PTAB activity means that the full scope of available prior-art grounds is open for challenge. An IPR could be a viable defense strategy to consider. Since there are no active proceedings, there are no trial-stage milestones to track.
