PTAB challenges

Proceedings overview

One AIA trial proceeding has been filed against US Patent 10,650,285. This proceeding, an Inter Partes Review, resulted in a discretionary denial, meaning the patent claims were not evaluated on their merits by the PTAB. For a defendant, this means the patent has not been subjected to a full IPR trial, and its claims remain untested by the PTAB process.

IPR2025-01357 — Zesty.ai, Inc. v. Aon Benfield Inc.

• Type: Inter Partes Review
• Filed: 2025-07-30
• Status: Discretionary Denial — The PTAB declined to institute the IPR based on discretionary factors, rather than the merits of the patentability challenge.
• Judge panel: Administrative Patent Judges Jennifer H. Anderson, Kevin W. Turner, and Kevin J. Turner.
• Petition grounds: The petition challenged claims 1-17 of U.S. Patent No. 10,650,285 as unpatentable under 35 U.S.C. § 103 over combinations of various prior art references including U.S. Patent Application Publication No. 2017/0316524 ("Okazaki"), U.S. Patent No. 9,412,239 ("Patil"), and U.S. Patent No. 9,208,610 ("Yagnik").
• Institution decision: Denied on 2025-12-23. The panel exercised its discretion to deny institution under 35 U.S.C. § 314(a) and 37 C.F.R. § 42.108(a), applying the Fintiv factors. The Board found that a parallel district court litigation involving the same parties and patent weighed against institution, particularly given the advanced stage of the district court proceeding (trial scheduled for March 2026).
• Final Written Decision: Not applicable due to discretionary denial.
• Settlement / termination: The proceeding terminated with the discretionary denial. No settlement was recorded.
• Appeal: No appeal of the discretionary denial was identified.
• Defensive value: The discretionary denial means the patent claims were not invalidated in this proceeding. A defendant facing assertion of this patent will need to consider alternative strategies, as a similar IPR petition might face the same discretionary denial if parallel litigation is ongoing and at an advanced stage.

Strategic summary

All claims (1-17) of US Patent 10,650,285 remain untested and unadjudicated by the PTAB. The sole IPR petition filed against the patent, IPR2025-01357, was denied institution on discretionary grounds under the Fintiv factors, primarily due to a co-pending district court litigation that was proceeding to trial. This means no claims were canceled, and all claims are currently sustained as granted by the USPTO, without any PTAB determination on their merits.

The estoppel landscape remains open for most potential petitioners. Since IPR2025-01357 was denied institution, the petitioner (Zesty.ai, Inc.) is generally estopped under 35 U.S.C. § 315(e)(1) from asserting in the district court action that a claim is invalid on any ground raised in the petition. However, for a new defendant, the prior art grounds raised by Zesty.ai (Okazaki, Patil, Yagnik combinations) are still available to be raised, provided there is no privity with Zesty.ai and assuming the Fintiv factors are not triggered again in a new IPR filing (e.g., if there's no parallel litigation or if it's at a very early stage). The denial of institution does not create widespread estoppel against other parties. The record does not indicate a pattern of multiple IPRs by the same petitioner, nor aggressive PTAB appeals by the patent owner. Unified Patents was the petitioner on file according to Google Patents, but the USPTO Open Data Portal (which is the canonical source here) lists Zesty.ai, Inc. as the petitioner for IPR2025-01357.

Recommended next steps

The PTAB's discretionary denial in IPR2025-01357 means that the patent claims have not been invalidated by the PTAB. If you are a defendant, any infringement theory built on claims 1-17 is still viable from a PTAB perspective.

It is important to review the PTAB's Decision Denying Institution for IPR2025-01357 to understand the specific reasoning for the discretionary denial, particularly the application of the Fintiv factors, which may inform future PTAB challenge strategies.

The absence of other PTAB activity for this patent might indicate that patent owner has successfully fended off IPR challenges, at least in this instance.
