PTAB challenges

Proceedings overview

There is one active AIA trial proceeding on file for US patent 11126889, which is currently in the "Trial Instituted" phase. This means that a challenge to the patent's claims has been found sufficiently compelling to proceed to a full trial before the Patent Trial and Appeal Board (PTAB). For a defendant facing assertion of this patent, this active IPR presents an opportunity for claims to be potentially invalidated, which could weaken the patent owner's position; however, no claims have been definitively canceled or sustained yet.

IPR2025-01574 — Tesla, Inc. v. Perceptive Automata LLC

• Type: Inter Partes Review
• Filed: 2025-10-02
• Status: Trial Instituted. The PTAB has determined that the petitioner, Tesla, Inc., has demonstrated a reasonable likelihood that at least one challenged claim of the patent is unpatentable, thus initiating a formal trial proceeding.
• Judge panel: The judge panel information for IPR2025-01574 is not publicly available in the provided patent text or readily accessible via general search without specific PTAB E2E docket access.
• Petition grounds: The patent document indicates "Prior art keywords: user, road, images, mind, autonomous vehicle" and the title "Machine learning based prediction of human interactions with autonomous vehicles," suggesting the IPR likely challenges claims related to these areas. However, the specific claims challenged, prior art cited, and statutory bases (§ 102 / § 103 / § 112) are not provided in the prompt and would require access to the petition itself.
• Institution decision: The proceeding status is "Trial Instituted" as of 2026-05-22. The specific date of the institution decision and the panel's detailed reasoning would be found in the institution decision document, which is not provided in the prompt or immediately accessible via general search. However, institution means the PTAB found that the petition demonstrated a reasonable likelihood that at least one challenged claim is unpatentable.
• Final Written Decision: Not yet issued. The proceeding is currently in the trial phase.
• Settlement / termination: Not applicable; the proceeding is active.
• Appeal: Not applicable; no Final Written Decision has been issued.
• Defensive value: This active IPR means that claims of US11126889 are currently being challenged by Tesla, Inc. If a defendant is being asserted against based on this patent, the outcome of this IPR could directly impact the strength of the patent owner's claims. While no claims are invalidated yet, the institution decision suggests that the PTAB believes Tesla has a reasonable chance of prevailing on at least some claims.

Strategic summary

All claims of US11126889 remain UNTESTED by a Final Written Decision in a PTAB proceeding. The single active IPR, IPR2025-01574, has been instituted, indicating that the PTAB found sufficient merit in Tesla's challenge to proceed to a full trial. This means that while no claims have been formally canceled, the validity of at least some claims is under serious scrutiny.

The estoppel landscape has not yet fully formed. Since IPR2025-01574 is still in the trial phase and no Final Written Decision has been issued, the statutory estoppel provisions of § 315(e)(2) do not yet apply. This means that if a defendant were to file their own IPR, they are not currently barred from raising grounds that Tesla raised or reasonably could have raised, though practical considerations might suggest coordination or waiting for Tesla's outcome. The petitioner for IPR2025-01574 is Tesla, Inc. The presence of Unified Patents in the litigation data and IPR data suggests a potential pattern of defensive aggregation or monitoring, although Unified Patents is not the petitioner in this specific IPR.

Recommended next steps

As IPR2025-01574 is currently active and in the "Trial Instituted" phase, key upcoming milestones include the filing of the Patent Owner Response, Petitioner Reply, any oral hearing, and ultimately the Final Written Decision. The PTAB has a statutory 1-year deadline to issue a Final Written Decision from the date of institution. To determine the precise FWD due date, the institution decision date would need to be identified. A defendant facing assertion should closely monitor the progress of IPR2025-01574. It is crucial to obtain and review the institution decision and the underlying petition to understand which claims are challenged and on what grounds. If the IPR results in claim invalidation, it could significantly impact any ongoing or potential infringement litigation.
