Strategic summary
As of the current date, all claims of US Patent 7,624,138 are UNTESTED by AIA trial proceedings. This means that no claims have been canceled or sustained through an IPR, PGR, or CBM. The estoppel landscape is entirely open, as there are no previous PTAB decisions to bar any petitioner (or their privies) from raising any ground they raised or reasonably could have raised against any claim of the patent. There are no pattern signals to discern regarding this patent owner's behavior in PTAB proceedings, nor any involvement from defensive aggregators.
Recommended next steps
The absence of PTAB activity suggests that the patent has not yet been rigorously challenged in post-grant proceedings. If facing assertion of this patent, a potential defendant could consider initiating an IPR against the patent, as the claims are currently untested and no prior art grounds have been foreclosed by previous PTAB decisions.
