The absence of PTAB activity indicates that there is no estoppel landscape to consider under § 315(e)(2) for potential future petitioners. All prior art grounds remain available for a defendant facing assertion of this patent, should they choose to pursue a PTAB challenge.
Recommended next steps
Since no PTAB activity exists for US11209863, a defendant facing assertion of this patent would need to consider other defensive strategies, including initiating their own AIA trial proceeding if suitable prior art can be identified. The absence of previous challenges suggests that this patent has not yet been thoroughly vetted in the PTAB forum.
