Strategic summary
Currently, all claims of US9977495 remain UNTESTED by any AIA trial proceedings. There are no canceled or sustained claims through IPR, PGR, or CBM.
Since no PTAB proceedings have been initiated, there is no estoppel landscape under § 315(e)(2) that would bar a future petitioner (or their privies) from raising any prior-art grounds. All prior-art grounds are still available for a potential challenger.
The absence of any PTAB activity suggests that this patent may not have been heavily asserted in litigation or that potential challengers have not yet pursued this avenue for invalidation. There is no pattern of multiple IPR filings, aggressive PTAB appeals by the patent owner, or involvement of defensive aggregators like Unified Patents.
Recommended next steps
Since no PTAB activity exists for US9977495, a defendant facing assertion of this patent has a full range of options for challenging its validity at the PTAB. There are no existing institution decisions, final written decisions, or Federal Circuit appeals to consider. The absence of PTAB activity itself is a signal, as well-asserted patents often attract IPRs.
