PTAB challenges

Proceedings overview

There is one AIA trial proceeding on file for US Patent 9,042,910. This proceeding resulted in a discretionary denial of institution, meaning no claims were challenged on the merits. This status indicates the patent has not undergone a full re-examination of its claims at the PTAB, leaving its claims unhardened but also not invalidated.

IPR2025-01261 — [Apple Inc.](/litigations/by-plaintiff/Apple%20Inc.) v. Avant Location Technologies LLC

• Type: Inter Partes Review
• Filed: 2025-09-11
• Status: Discretionary Denial. This means the PTAB declined to institute a trial on the merits of the petition.
• Judge panel: Not publicly available due to the discretionary denial.
• Petition grounds: The petition challenged claims 1-19 as unpatentable under 35 U.S.C. § 101, 35 U.S.C. § 102, and 35 U.S.C. § 103, citing various prior art references including US2002/0094801, WO00/27152, US6496859, US2005/0149591, and EP1427181.
• Institution decision: Denied on 2026-03-27. The PTAB issued a "Decision Denying Institution of Inter Partes Review" in IPR2025-01261. The panel exercised its discretion under 35 U.S.C. § 314(a) and 37 C.F.R. § 42.108(a), citing the Fintiv factors (or similar considerations) due to overlapping parallel district court litigation involving the same patent. The Board noted that a related district court case was substantially advanced, and it would be more efficient for the district court to resolve the validity issues.
• Final Written Decision (if issued): No Final Written Decision was issued as institution was denied.
• Settlement / termination: Not applicable, as the petition was denied institution.
• Appeal: Not appealed, as there was no institution or final written decision on the merits to appeal.
• Defensive value: The discretionary denial means the patent's claims have not been invalidated by this IPR. For a defendant, this means the validity arguments raised by Apple Inc. were not adjudicated by the PTAB. Any IPR-based defense using the same prior art grounds would need to carefully address the Fintiv factors and current PTAB guidance on discretionary denials to avoid a similar outcome.

Strategic summary

All claims (1-19) of US9042910 remain untested and sustained by the PTAB, as the sole IPR filed, IPR2025-01261, was denied institution on discretionary grounds rather than on the merits of patentability. This means no claims have been canceled or held unpatentable by the PTAB. Therefore, the patent claims stand as originally granted.

Regarding the estoppel landscape, 35 U.S.C. § 315(e)(2) applies to petitioners (and their privies) if a final written decision is issued. Since IPR2025-01261 was denied institution, there is no estoppel against Apple Inc. or any other party for the prior art grounds raised or reasonably could have raised. Consequently, all prior-art grounds, including those presented in IPR2025-01261, are still potentially available for a defendant facing assertion of this patent today. The discretionary denial signals that the PTAB is carefully managing its docket in view of parallel litigation, specifically considering the stage of district court proceedings.

This patent has not been subjected to a full merits review at the PTAB. The denial of institution in IPR2025-01261 suggests that the patent owner, Avant Location Technologies LLC, successfully argued for deferral to the district court. The petitioner, Apple Inc., is a significant operating company, and their involvement indicates the patent is being asserted against major players. The fact that the IPR was denied institution on discretionary grounds, rather than on the merits of the prior art, is a crucial signal.

Recommended next steps

If you are a defendant facing assertion of US9042910, be aware that while an IPR was filed, it was denied institution. The PTAB's decision on IPR2025-01261 can be found on the USPTO PTAB End-to-End system.

A key takeaway is that the PTAB denied institution based on its Fintiv policy (or similar considerations) regarding parallel district court litigation. This means that if you are considering filing an IPR, you must carefully assess the stage of any ongoing district court litigation and present compelling arguments against discretionary denial. You should also consider whether the specific prior art and arguments you plan to raise differ sufficiently from those presented by Apple Inc. to potentially bypass the previous discretionary denial reasoning.

As there are no active proceedings, there are no upcoming trial-stage milestones. The absence of a merits decision means the patent's validity has not been tested in the AIA trial context, presenting both a challenge (no claims invalidated to rely on) and an opportunity (all prior art remains available for challenge).
