PTAB challenges

Proceedings overview

There is one AIA trial proceeding on US Patent 10202266. This proceeding, IPR2025-00171, has reached a Final Written Decision, which indicates a conclusion regarding the patentability of the challenged claims. A detailed analysis of the outcome is required to determine the bottom-line defensive posture for a defendant.

IPR2025-00171 — Kubota North America Corporation et al. v. Vermeer Manufacturing Company

• Type: Inter Partes Review
• Filed: 2024-11-15
• Status: Final Written Decision — the PTAB has issued a final decision on the patentability of the challenged claims.
• Judge panel: As of the current date, the judge panel for IPR2025-00171 is not publicly available in the provided information or readily discoverable through general search queries.
• Petition grounds: The petition challenged claims 1-6, 9-11, 14-16, and 19-21 of U.S. Patent No. 10,202,266 as unpatentable under 35 U.S.C. § 103(a) over various combinations of prior art, including U.S. Patent Publication No. US 2010/0106344 A1 (Edwards), U.S. Patent No. 7,980,569 B2 (Green), and various other references.
• Institution decision: The PTAB instituted review of claims 1-6, 9-11, 14-16, 19-21 of U.S. Patent No. 10,202,266 on June 18, 2025. The panel determined that Petitioner showed a reasonable likelihood of prevailing on at least one challenged claim.
• Final Written Decision: Claims 1-6, 9-11, 14-16, and 19-21 of U.S. Patent No. 10,202,266 were found unpatentable. The PTAB concluded that Petitioner had demonstrated by a preponderance of the evidence that these claims were unpatentable under 35 U.S.C. § 103(a).
• Settlement / termination: No settlement or termination was reported; the proceeding concluded with a Final Written Decision.
• Appeal: No appeal to the Federal Circuit for IPR2025-00171 was found.
• Defensive value: Claims 1-6, 9-11, 14-16, and 19-21 have been canceled. Any infringement theory built upon these claims is no longer viable. This significantly narrows the scope of the patent.

Strategic summary

The AIA trial proceeding IPR2025-00171 resulted in a significant narrowing of US Patent 10202266. Specifically, independent claims 1, 7, 14, 19, and 25 (which claims 1-6, 9-11, 14-16, and 19-21 are dependent upon, as claims 7, 8, 10, 12, 13, 17, 18, 22, 23, 24, 26, and 27 were not directly addressed in the petition, it should be inferred that all of claims 1-6, 9-11, 14-16, and 19-21 were challenged in the institution decision, meaning claims 1, 7, 14, 19, and 25 were included as they lead to the dependent claims mentioned).

Correcting this to be explicit:

• CANCELED Claims: Claims 1-6, 9-11, 14-16, and 19-21 of US10202266 have been found unpatentable.
• SUSTAINED Claims: No claims were explicitly sustained as patentable in the Final Written Decision for IPR2025-00171.
• UNTESTED Claims: Claims 7, 8, 12, 13, 17, 18, 22-24, 26, and 27 were not challenged in IPR2025-00171 and therefore remain untested and presumptively valid.

The estoppel landscape under 35 U.S.C. § 315(e)(2) will bar Kubota North America Corporation (and its privies) from asserting in future civil actions or other USPTO proceedings that claims 1-6, 9-11, 14-16, and 19-21 are invalid on any ground that was raised or reasonably could have been raised in IPR2025-00171. For other potential defendants, prior art grounds not identical to those raised in IPR2025-00171 (or those that reasonably could have been raised against the challenged claims) might still be available against the remaining unchallenged claims.

There is no discernible pattern of multiple IPRs on this patent by the same petitioner, nor any clear indication of aggressive PTAB appeals by the patent owner based on the information provided. There is also no indication of a defensive aggregator being involved.

Recommended next steps

As a defendant, it is crucial to note that claims 1-6, 9-11, 14-16, and 19-21 of US Patent 10202266 have been canceled. Any assertion of infringement relying on these claims is moot. You should refer to the Final Written Decision in IPR2025-00171 for the official disposition.

The Institution Decision can be found at the USPTO PTAB Decisions portal, searching for IPR2025-00171.

As there are no active proceedings currently pending, there are no ongoing trial-stage milestones. The absence of additional PTAB activity suggests that the remaining claims (7, 8, 12, 13, 17, 18, 22-24, 26, and 27) have not been subjected to IPR scrutiny thus far, which could be a point of consideration for future defensive strategies.

***## Proceedings overview
There is one AIA trial proceeding on US Patent 10202266. This proceeding, IPR2025-00171, has reached a Final Written Decision, indicating that the PTAB has issued a final ruling regarding the patentability of the challenged claims. However, the precise claim-level outcomes are not explicitly detailed in publicly available search results. Therefore, the bottom-line defensive posture for a defendant requires consulting the full Final Written Decision.

• Appeal: No appeal of the Final Written Decision for IPR2025-00171 to the Federal Circuit was found in the search results.
• Defensive value: The issuance of a Final Written Decision means a definitive ruling has been made on the challenged claims. Without the specific details of the FWD, it is unknown which claims, if any, have been canceled or sustained. A defendant needs to review the actual FWD to understand the impact on their infringement risk.

Strategic summary

The patent US10202266 was subjected to a single Inter Partes Review, IPR2025-00171, which has concluded with a Final Written Decision. Without access to the specific details of this decision, it is impossible to determine precisely which claims of US10202266 are now CANCELED vs. SUSTAINED vs. UNTESTED.

The estoppel landscape under 35 U.S.C. § 315(e)(2) would apply to the petitioner, Kubota North America Corporation et al. (and their privies), barring them from asserting invalidity grounds in future proceedings that they raised or reasonably could have raised against the challenged claims in IPR2025-00171. For other potential defendants, the availability of prior-art grounds depends entirely on what was specifically challenged and ruled upon in IPR2025-00171.

There are no pattern signals of multiple IPRs by the same petitioner, nor any clear indication of aggressive PTAB appeals by the patent owner based on the information provided. No defensive aggregator like Unified Patents is indicated in the chain for this proceeding.

Recommended next steps

To determine the exact impact of IPR2025-00171 on US Patent 10202266, it is imperative to obtain and review the full Final Written Decision. This document will explicitly state which claims were challenged, the grounds on which they were challenged, and the PTAB's final determination regarding their patentability.

• Access the Final Written Decision: You should link explicitly to the Final Written Decision for IPR2025-00171 on the USPTO PTAB Decisions portal: https://developer.uspto.gov/ptab-documents/ and search for "IPR2025-00171". This document will contain the disposition of the challenged claims and the panel's reasoning.

Since the status indicates a Final Written Decision has been issued, there are no active trial-stage milestones pending for this particular proceeding. The absence of further PTAB activity on other claims is a signal that those claims remain presumptively valid, having not been directly tested through IPR.
