PTAB challenges

Proceedings overview

There is one active AIA trial proceeding on US patent 10771069, currently in the "Pending" status. This means the patent's claims are still being challenged, and the full defensive posture for a defendant will depend on the outcome of this ongoing IPR.

IPR2026-00386 — Optiver US LLC et al. v. HFT Solutions LLC

• Type: Inter Partes Review
• Filed: 2026-06-04
• Status: Pending. The petition has been filed, and the PTAB is currently reviewing it to determine whether to institute a trial.
• Judge panel: Not yet public.
• Petition grounds: Not yet public. The petition was filed too recently for this information to be publicly available.
• Institution decision: Not yet issued. The deadline for the institution decision is typically within six months of the preliminary response or the last due date for such a response.
• Final Written Decision (if issued): Not applicable.
• Settlement / termination: Not applicable.
• Appeal: Not applicable.
• Defensive value: This proceeding indicates that Optiver US LLC et al. are challenging the patent. For a defendant, this means there is an active challenge to the patent's validity, and the outcome of this IPR could significantly impact the strength of any assertion based on US10771069. If the IPR is instituted and claims are invalidated, it could weaken the patent owner's position. Conversely, if institution is denied or claims are upheld, it could strengthen the patent.

Strategic summary

Currently, all claims of US10771069 are legally considered untested in the context of an AIA trial, as the single IPR filed (IPR2026-00386) is still in the pending stage, awaiting an institution decision. No claims have been canceled or sustained through a Final Written Decision. This means that the patent's scope remains as granted by the USPTO.

The estoppel landscape is presently undeveloped. Since no institution decision or FWD has been issued, there are no prior art grounds that are yet barred from being raised by the petitioner (or its privies) under § 315(e)(2) for this specific IPR. For a defendant facing assertion of this patent, all prior art grounds remain potentially available for use in a future IPR or other validity challenges, assuming they are not in privity with Optiver US LLC et al.

The filing of this IPR by Optiver US LLC et al. suggests that they perceive vulnerabilities in the patent's claims. There is no public information at this time to suggest a pattern of multiple IPR filings by the same petitioner, aggressive appeals by the patent owner, or involvement of a defensive aggregator.

Recommended next steps

For a defendant facing assertion of US10771069, monitoring IPR2026-00386 is crucial. The key upcoming milestone is the institution decision. The PTAB has a statutory deadline of one year from institution to issue a Final Written Decision.
