Consequently, there is no estoppel landscape established by PTAB decisions for this patent under 35 U.S.C. § 315(e)(2).

Recommended next steps

Since no PTAB activity exists for US Patent 10944400, a potential defendant has full flexibility to raise any available prior-art grounds in a future AIA trial proceeding (IPR or PGR, if applicable) without being estopped by prior PTAB decisions related to this patent. The absence of PTAB challenges for a patent, especially one that has been involved in district court litigation (as noted in the patent summary), could indicate either that prior art suitable for IPR/PGR has not been found or that parties have opted for other dispute resolution mechanisms.
