Strategic summary
As of 2026-05-29, there are no recorded PTAB proceedings, such as Inter Partes Reviews (IPRs), Post-Grant Reviews (PGRs), or Covered Business Method (CBM) reviews, related to US Patent 8772416. This means that all claims (1-19) of the patent remain untested and sustained from a PTAB perspective. The absence of PTAB challenges can suggest several things: the patent may not have been aggressively asserted, potential challengers may have found the claims robust, or assertion activities have not yet triggered such challenges.
Since no PTAB proceedings have occurred, there is no estoppel landscape established under 35 U.S.C. § 315(e)(2). Therefore, all prior-art grounds that could be raised in a PTAB petition against this patent remain available to a potential petitioner or defendant.
Recommended next steps
If facing an assertion of US Patent 8772416, a potential defendant would need to conduct their own prior art search and analysis to identify grounds for invalidity, which could then form the basis for a PTAB petition (e.g., IPR or PGR, depending on the claims and filing dates). The absence of PTAB activity means that the claims have not been subjected to the scrutiny of an AIA trial, and their validity against prior art remains open for challenge.
