Strategic summary
As there are no PTAB proceedings on file, all claims of US Patent 11419787 remain untested by AIA trials. This means that a defendant facing assertion of this patent would have a full range of prior-art grounds available for a potential IPR, PGR, or CBM petition, assuming statutory requirements are met. The absence of PTAB activity could suggest that the patent has not yet been aggressively asserted in a way that would provoke such challenges, or that potential challengers have opted for other defensive strategies.
Recommended next steps
If you are a defendant facing assertion of US Patent 11419787, and there are no PTAB proceedings on file, a thorough prior art search would be a critical first step. Based on the findings, initiating an AIA trial (such as an Inter Partes Review) could be a viable strategy to challenge the patentability of the asserted claims. The absence of prior PTAB challenges means there is no estoppel against raising any patentability grounds.
