Strategic summary
As of today, US20170193836A1 has no claims that are canceled, sustained, or untested by the PTAB through AIA trial proceedings. All claims within the patent remain as they were granted, as there has been no PTAB activity to challenge or confirm their patentability. This absence of PTAB proceedings suggests that the patent has not yet been subject to the scrutiny of an IPR, PGR, or CBM.
The estoppel landscape under 35 U.S.C. § 315(e)(2) is not applicable here, as no AIA trial proceedings have been instituted.
