My initial search for PTAB proceedings related to US Patent 11871174 did not yield any relevant results. The search terms primarily returned information about "PGR Stock" (Progressive Corporation), which is unrelated to patent proceedings. This confirms the information from the structured "PTAB proceedings on file" block that states "The USPTO ODP API returns no AIA trial proceedings for this patent as of the most recent ingest."
Therefore, there is no PTAB activity on file for US Patent 11871174.
Proceedings overview
There are no AIA trial proceedings (Inter Partes Review, Post-Grant Review, or Covered Business Method) on file for US Patent 11871174. This means the patent's claims have not been challenged at the Patent Trial and Appeal Board (PTAB), and it stands with all claims untested in that forum. This gives a defendant no immediate defensive advantage from PTAB invalidations; any challenge would need to be a new filing.
Strategic summary
As of May 30, 2026, all claims of US 11871174 are UNTESTED at the Patent Trial and Appeal Board. There are no records of any IPR, PGR, or CBM proceedings having been filed against this patent. Consequently, there is no estoppel landscape from PTAB decisions to consider, as no grounds have been raised or ruled upon by the Board. The absence of PTAB activity suggests that the patent's validity has not yet been directly challenged by third parties in an AIA trial.
Recommended next steps
- Since no PTAB activity exists for US 11871174, a defendant facing assertion of this patent would need to consider initiating a new AIA trial (e.g., an Inter Partes Review) if they wish to challenge the patent's validity before the PTAB. The decision to file an IPR should be made carefully, considering the strength of available prior art and the one-year statutory bar from service of a complaint.
- The fact that no IPRs have been filed could indicate several things: the patent owner may not have vigorously asserted the patent yet, potential challengers may have found other avenues, or the patent's claims might be perceived as difficult to challenge under the IPR standards.
