Strategic summary

As there are no PTAB proceedings on record for US Patent 9,289,645, all claims of the patent remain UNTESTED by an AIA trial. This means there have been no administrative decisions from the PTAB regarding the patentability of claims 1, 11, and 12 (or any other claims).

Consequently, there is no estoppel landscape established under 35 U.S.C. § 315(e)(2) for this patent through PTAB proceedings. All prior art grounds that could be raised in an IPR, PGR, or CBM are theoretically still available for a potential petitioner. There is no pattern of PTAB challenges or appeals by the patent owner or any defensive aggregators like Unified Patents on this specific patent.

Recommended next steps

Since no PTAB activity exists for US Patent 9,289,645, a potential defendant currently facing assertion of this patent should consider the absence of such challenges as a signal. While it might suggest the patent has not been a frequent target, it also means its claims have not been subjected to the scrutiny of an AIA trial.

For a defendant, the recommended next steps would be:

  • Prior Art Search: Conduct a thorough prior art search to identify any relevant art that could form the basis for an IPR or PGR petition.
  • Validity Analysis: Perform a detailed validity analysis of all asserted claims against the identified prior art, including a review under 35 U.S.C. §§ 102, 103, and 112.
  • Consider PTAB Petition: If strong prior art is found, evaluate the viability of filing an Inter Partes Review petition (IPR) to challenge the patent's claims at the PTAB. Since no IPRs have been filed, a potential petitioner would not be subject to any existing estoppel.
  • Monitor for new filings: Regularly monitor the PTAB E2E system and other litigation databases for any newly filed petitions against US9289645.
