Strategic summary
As of today, May 29, 2026, there are no AIA trial proceedings (IPR, PGR, or CBM) on file for US patent 8374096 according to the USPTO ODP API. This means all claims of US8374096 remain untested by the PTAB.
The absence of PTAB activity could indicate several things. It might suggest that the patent has not been extensively asserted, or that previous assertions have not prompted defendants to challenge the patent's validity at the PTAB. It could also mean that the patent is relatively recent, or that its claims are perceived as robust against common prior art challenges.
Recommended next steps
Given the lack of PTAB activity, a defendant facing assertion of US8374096 would have a full range of prior-art grounds available for an IPR or PGR petition, should they choose to pursue that avenue. Without any prior challenges, there is no estoppel landscape to consider from previous AIA trials.
