Proceedings overview
There is no PTAB activity on file for US Patent 7817208. This means the patent has not yet been challenged in an AIA trial proceeding, giving a defendant a wide range of potential prior art grounds to pursue if facing assertion.
Strategic summary
As there are no PTAB proceedings on file for US7817208, all claims of the patent remain untested in an AIA trial setting. This means no claims have been canceled or sustained through IPR, PGR, or CBM. Consequently, the estoppel provisions of 35 U.S.C. § 315(e)(2) do not apply, leaving all prior-art grounds open for potential future petitioners. The absence of PTAB activity suggests that either the patent has not been extensively asserted, or prior challenges have not taken the form of AIA trials.
Recommended next steps
If you are a defendant facing assertion of US7817208, consider evaluating the patent for potential IPR challenges. The lack of prior PTAB proceedings means that a wide range of prior art and invalidity arguments are available. No specific deadlines for PTAB milestones are applicable since no proceedings have been initiated.
