Proceedings overview
There are no AIA trial proceedings on file for US Patent 11,419,823 as of the most recent ingest.
Strategic summary
Currently, all claims of US Patent 11,419,823 remain unchallenged and sustained. The absence of PTAB activity suggests that the patent has not yet been subjected to an inter partes review (IPR), post-grant review (PGR), or covered business method (CBM) review. This means there is no estoppel landscape established through AIA trials that would bar potential petitioners from raising any prior-art grounds.
Recommended next steps
Since there is no PTAB activity on file for US Patent 11,419,823, a potential defendant facing assertion of this patent has a full range of prior-art grounds available for an IPR or PGR petition, should they choose to pursue that avenue. The absence of PTAB challenges for a patent that has been in litigation in district court (as noted in the patent summary) could be a signal that potential challengers have not yet identified strong prior art grounds or chosen to litigate in that forum.
