Strategic summary
As there are no PTAB proceedings on file for US Patent 10423918, all claims (1-19) remain unchallenged and are presumed valid. This means that a defendant facing assertion of this patent currently faces all claims as originally granted. Without any PTAB history, there is no estoppel landscape established under 35 U.S.C. § 315(e)(2), leaving all prior-art grounds available for potential challenge. The absence of PTAB activity could indicate that the patent has not yet been heavily asserted or that potential challengers have not found sufficiently compelling grounds to file a petition.
Recommended next steps
Since no PTAB activity exists for US Patent 10423918, a potential defendant would need to initiate a new AIA trial if they wish to challenge the patent's validity before the PTAB. This would involve a thorough prior art search to identify grounds for invalidity under 35 U.S.C. §§ 102 or 103, followed by the preparation and filing of a petition for Inter Partes Review (IPR). The absence of prior challenges means there is a clean slate to present any viable prior art.
