Proceedings overview
There are no AIA trial proceedings on file for US Patent 7364736B2 as of 2026-05-29. This means the patent has not been subjected to IPR, PGR, or CBM challenges, and its claims remain untested by the PTAB.
Strategic summary
All claims of US7364736B2 remain untested by the PTAB. There are no canceled, sustained, or invalidated claims to report from AIA trial proceedings. Consequently, there is no estoppel landscape established by the PTAB for this patent, and all prior-art grounds remain available for a potential future challenger. The absence of any PTAB activity suggests that the patent has not yet faced an IPR challenge, which is a common defensive maneuver for patents that are actively asserted or license-demanded.
Recommended next steps
As there is no PTAB activity on file for US7364736B2, a defendant currently facing assertion of this patent should be aware that all claims are currently presumed valid as far as PTAB proceedings are concerned. The absence of prior PTAB challenges means that any potential prior art could form the basis of a new IPR, PGR, or CBM petition, depending on the patent's eligibility. The default position of "no PTAB activity on file" for a patent published in 2008 suggests either a lack of aggressive assertion activity leading to challenges or that prior art sufficient for institution has not yet been identified and leveraged by potential petitioners.
