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
There are no AIA trial proceedings (Inter Partes Review, Post-Grant Review, or Covered Business Method) on file for US patent 11369322. The USPTO ODP API reports no proceedings as of its most recent ingest, and a web search did not surface any additional or recently-filed proceedings. This means the patent has not been challenged at the PTAB, offering no specific defensive posture from prior PTAB outcomes for a potential defendant.
Strategic summary
As of the current date (2026-06-02), all 20 claims of US11369322 remain untested and are considered sustained by the PTAB simply due to the absence of any challenges. No claims have been canceled or invalidated through an AIA trial proceeding.
Estoppel landscape: Since no AIA trial proceedings have been instituted or concluded, there is no estoppel under 35 U.S.C. § 315(e)(2) for any petitioner or their privies concerning US11369322. All prior art grounds (e.g., § 102 or § 103 challenges) remain available for potential future IPR or PGR petitions.
Pattern signals: The absence of PTAB activity suggests that this patent, despite being granted in 2022 and having a priority date stretching back to 2007, has not yet been asserted in a way that would provoke an AIA trial, or potential infringers have not yet deemed it worthwhile to challenge at the PTAB. There is no pattern of aggressive PTAB appeals by the patent owner or involvement of defensive aggregators.
Recommended next steps
Given the absence of any PTAB activity, a potential defendant should be aware that the claims of US11369322 have not been judicially vetted for patentability against prior art in an IPR or PGR.
If facing an assertion of this patent:
- Prior Art Search: Conduct a thorough prior art search to identify potential invalidity grounds under 35 U.S.C. § 102 and § 103, as these grounds remain entirely open for a future PTAB petition.
- Claim Analysis: Perform a detailed claim construction and infringement analysis for all asserted claims.
- Evaluation of PTAB Challenge: Consider whether filing an IPR or PGR petition would be a viable strategy, particularly if strong prior art can be identified. The absence of previous challenges means that a petitioner would not be estopped from raising any grounds.
