Proceedings overview
The USPTO Open Data Portal indicates no AIA trial proceedings on file for US Patent 11,798,576 as of the most recent ingest. A supplementary web search for IPR, PGR, or CBM proceedings related to this patent also yielded no results. Therefore, there are no PTAB proceedings, neither active nor concluded, concerning US Patent 11,798,576. This gives a defendant a posture where the patent's claims remain untested by AIA trials.
Strategic summary
As of today's date, May 29, 2026, all claims of US Patent 11,798,576 (Claims 1-20) are UNTESTED in AIA trial proceedings. No inter partes reviews (IPRs), post-grant reviews (PGRs), or covered business method (CBM) reviews have been filed against this patent. Consequently, there is no estoppel landscape established by PTAB decisions under 35 U.S.C. § 315(e)(2), meaning all prior-art grounds remain available for a potential future petitioner. The absence of PTAB activity suggests that the patent has not yet been aggressively asserted in litigation that would provoke such challenges, or that potential challengers have not yet identified strong grounds for an AIA trial.
Recommended next steps
Since no PTAB activity exists for US Patent 11,798,576, the recommended next steps for a potential defendant are as follows:
- Conduct a thorough prior art search: With no prior art having been tested at the PTAB, a defendant facing assertion of this patent should invest in a robust prior art search to identify potential invalidity grounds for an IPR or district court defense.
- Monitor for future filings: Continue to monitor the PTAB's E2E system (e.g., via the USPTO PTAB Decisions portal or Docket Navigator) for any newly filed petitions against US 11,798,576, as the absence of past filings does not preclude future challenges.
- Evaluate IPR potential: If an assertion of this patent is received, a detailed analysis should be conducted to evaluate the strength of an IPR petition, considering the independent claims (1, 12, 18) and the sufficiency of identified prior art. The claims remain entirely untested, which can present both an opportunity and a challenge for a defendant.
