Proceedings overview
There are no AIA trial proceedings currently on file for US patent 11516694. This means the patent has not been challenged in an Inter Partes Review (IPR), Post-Grant Review (PGR), or Covered Business Method (CBM) proceeding at the Patent Trial and Appeal Board (PTAB). This gives a defendant currently facing assertion of this patent the defensive posture that all claims remain untested by PTAB.
Strategic summary
As of May 22, 2026, all claims (1-20) of US patent 11516694 are considered valid and untested by any AIA trial proceeding. There are no canceled, sustained, or narrowed claims resulting from PTAB challenges. Consequently, the estoppel landscape is clear; there are no prior-art grounds that are barred from being raised in a new PTAB petition or in district court litigation due to a previous PTAB final written decision. There are no pattern signals to observe, as no proceedings have been initiated.
Recommended next steps
Since no PTAB activity exists for US11516694B1, a defendant facing assertion of this patent should be aware that the claims have not been subjected to the scrutiny of an AIA trial. The absence of PTAB activity can be a signal that the patent has not been widely asserted or that potential challengers have not yet found compelling prior art to pursue an IPR.
For a defendant, the next steps could include:
- Conducting a thorough prior art search to identify potential invalidity grounds under 35 U.S.C. §§ 102 and 103, which could form the basis for a new IPR petition.
- Assessing the commercial relevance and strength of the asserted claims in light of the prior art found, to determine the viability of a PTAB challenge.
- Monitoring for any newly filed PTAB petitions against this patent, as such filings would change the defensive landscape.
