Strategic summary
All claims of US Patent 11356947 remain untested by AIA trial proceedings. This means that a potential defendant facing assertion of this patent would have all prior art grounds available for a new Inter Partes Review petition, as there is no estoppel from previous challenges under § 315(e)(2). The absence of PTAB activity is a notable signal; well-asserted patents often become targets for IPRs, suggesting that this patent may not have been aggressively asserted or that previous assertions have not led to PTAB challenges by defendants.
