Strategic summary

There is no estoppel landscape from PTAB proceedings to consider, as no petitions have been filed. The absence of PTAB activity could signal that the patent has not been extensively asserted in a manner that would typically provoke IPR filings, or that potential challengers have not found strong prior art grounds to pursue such actions.
Recommended next steps
If you are a defendant facing assertion of US Patent 7267820, it is important to note that the patent's claims have not been subject to PTAB review. This means that all claims are currently considered patentable as far as PTAB proceedings are concerned. A thorough prior art search would be a crucial next step to identify potential grounds for an Inter Partes Review (IPR) should the patent be asserted. The absence of PTAB activity suggests that this could be a viable avenue for a defendant to explore, as the patent has not been "hardened" by surviving previous PTAB challenges.
