PTAB challenges

Proceedings overview

There is one active AIA trial proceeding on US patent 10741071. The Inter Partes Review (IPR) is currently pending, meaning no claims have been invalidated or sustained by the PTAB yet. This gives a defendant facing assertion of this patent an opportunity to monitor the ongoing challenge and potentially use its outcome in defense.

IPR2026-00309 — Uber Technologies, Inc. et al. v. Carma Technology Ltd

• Type: Inter Partes Review
• Filed: 2026-03-12
• Status: Pending – The proceeding is ongoing, and no institution decision has been reached yet.
• Judge panel: Information not publicly available at this early stage of the proceeding.
• Petition grounds: Information regarding specific claims challenged, prior art, and statutory bases (§ 102 / § 103 / § 112) is not yet publicly detailed in the provided information or readily available from initial searches for a pending IPR.
• Institution decision: Not yet issued. The statutory deadline for the institution decision is typically six months from the filing date, which would be around September 12, 2026.
• Final Written Decision (if issued): Not applicable; no decision has been issued as the proceeding is still pending.
• Settlement / termination: Not applicable; the proceeding is still pending.
• Appeal: Not applicable; no Final Written Decision has been issued.
• Defensive value: As this IPR is in its early stages, it represents a live challenge to the patent. A defendant should closely track this proceeding, as a decision to institute, especially on certain claims, could significantly impact the patent's strength and provide valuable art for a defense. Conversely, a denial of institution or an unfavorable outcome for the petitioner would harden the patent against future similar challenges.

Strategic summary

As of today, May 29, 2026, all claims of US patent 10741071 remain UNTESTED by a final PTAB decision. The single IPR, IPR2026-00309, is currently pending, meaning the PTAB has not yet decided whether to institute a trial. Therefore, no claims have been canceled or sustained by the PTAB.

The estoppel landscape under § 315(e)(2) is not yet relevant as no final written decision has been issued. If the IPR proceeds to a Final Written Decision, Uber Technologies, Inc. et al. (and their privies) would be estopped from asserting grounds raised or that reasonably could have been raised in that IPR. For other potential defendants, all prior-art grounds remain available until a Final Written Decision is issued.

The petitioner, Uber Technologies, Inc. et al., has filed one IPR on this patent. This indicates a targeted challenge by a potential implementer or competitor. The involvement of Unified Patents as a source in the Google Patents listing for this PTAB case (IPR2026-00309 filed (Pending) - Petitioner: Unified Patents PTAB Data) suggests a defensive aggregator is involved, which often signals a broader industry interest in challenging the patent.

Recommended next steps

Given that IPR2026-00309 is pending, a defendant should closely monitor its progress. The key near-term milestone to watch for is the institution decision, which is expected around September 12, 2026. This decision will indicate whether the PTAB believes there is a reasonable likelihood that at least one challenged claim is unpatentable, based on the grounds presented by Uber. If the PTAB institutes the IPR, the defendant should analyze the institution decision to understand which claims and prior art grounds are proceeding to trial, as this will provide significant insights into the patent's vulnerability.
