Proceedings overview
There are no AIA trial proceedings on file for US patent 9854402. The USPTO ODP API currently shows no records of such proceedings, and a web search did not surface any older or recently-filed proceedings. This gives a defendant a posture where the patent's claims have not been challenged or altered through IPR, PGR, or CBM trials at the PTAB.
Strategic summary
As of 2026-05-31, all claims of US9854402 remain untested in AIA trial proceedings at the PTAB. There are no canceled or sustained claims from IPR, PGR, or CBM reviews. Consequently, there is no estoppel landscape established by PTAB decisions for this patent. The absence of PTAB activity suggests that, as of now, no party has initiated such a challenge or that any such challenges have not been publicly recorded or concluded in a manner discoverable via public web search.
Recommended next steps
No PTAB activity exists for US patent 9854402. This absence is a signal that the patent's claims have not been subject to the rigorous scrutiny of an AIA trial. A defendant facing assertion of this patent would therefore need to consider initiating a new IPR or PGR proceeding if they wish to challenge the patent's validity before the PTAB.
