The estoppel landscape is entirely open, as no petitioner has brought a challenge that would bar future parties from raising prior-art grounds. The absence of PTAB activity suggests that, while the patent is active, it has not yet faced the scrutiny of an AIA trial, which is a common occurrence for well-asserted patents.
