The absence of PTAB activity suggests that the patent owner, Caterpillar Inc., has either not extensively asserted this patent in a way that would trigger PTAB challenges, or potential challengers have not found sufficiently compelling grounds for an AIA trial.
Recommended next steps
Since no PTAB activity exists for US Patent 9347554, there are no specific FWDs or pending trial-stage milestones to reference. For a defendant facing assertion of this patent, this means that all claims are currently presumed valid from a PTAB perspective. A defensive strategy could involve initiating an IPR if strong prior art grounds can be identified, as the patent has not yet been "hardened" by surviving such challenges.
