Consequently, there is no estoppel landscape established by PTAB decisions for this patent under 35 U.S.C. § 315(e)(2). The patent owner has not faced any challenges to the patentability of these claims in IPR, PGR, or CBM proceedings.
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.
