Proceedings overview
The USPTO ODP API returns no AIA trial proceedings for this patent as of the most recent ingest. There is no PTAB activity on file for US Patent 11,431,431. This means all claims (1-9) of the patent remain untested at the PTAB.
Strategic summary
Currently, all claims of US 11,431,431 (claims 1-9) are UNTESTED at the PTAB. This means there are no claims that have been canceled or sustained in an AIA trial.
Since there are no PTAB proceedings, the estoppel landscape under § 315(e)(2) is currently clear. No petitioner, nor their privies, has been barred from raising any ground they raised or reasonably could have raised against this patent. For a defendant currently being asserted against, all prior-art grounds remain available for a potential IPR petition. There are no patterns of multiple IPR filings on this patent, nor has the patent owner pursued PTAB appeals related to IPRs. There is no indication of a defensive aggregator like Unified Patents in any PTAB proceedings for this patent.
Recommended next steps
If you are a defendant facing assertion of US 11,431,431, the absence of PTAB activity suggests that the patent has not yet faced a direct challenge to its validity through this forum. This could mean that potential prior art arguments have not been fully explored or tested in an efficient administrative setting. As such, considering an IPR petition against the patent's claims would be a viable defensive strategy.
