PTAB challenges

Proceedings overview

There is one AIA trial proceeding on file for US Patent 10,541,279. The proceeding, IPR2025-01476, was terminated due to a settlement. This means the patent has not been subjected to a final written decision on the merits, and no claims have been invalidated or sustained by the PTAB. Therefore, the defensive posture for a defendant is that the patent claims remain untested by the PTAB.

IPR2025-01476 — BOE Technology Group Co., Ltd. et al. v. Samsung Display Co Ltd

• Type: Inter Partes Review
• Filed: 2025-08-31
• Status: Terminated-Settled
• Judge panel: Not publicly available at this stage of termination.
• Petition grounds: Not publicly available due to termination.
• Institution decision: Not applicable; the proceeding was terminated prior to an institution decision.
• Final Written Decision (if issued): Not issued; the proceeding was terminated prior to a final written decision.
• Settlement / termination: The proceeding was terminated on 2026-01-06 due to a settlement between BOE Technology Group Co., Ltd. et al. (Petitioner) and Samsung Display Co Ltd (Patent Owner). The specific terms of the settlement are confidential.
• Appeal: No appeal to the Federal Circuit occurred as no Final Written Decision was issued.
• Defensive value: This IPR does not offer a direct defensive advantage in terms of claim invalidation, as it settled before a decision on the merits. However, the fact that an IPR was filed and subsequently settled might indicate that the petitioner found sufficient grounds to challenge the patent's validity, even if those grounds were not ultimately litigated to a final decision. The patent owner chose to settle rather than pursue the IPR to a Final Written Decision, which could be interpreted in various ways, but does not definitively harden the patent.

Strategic summary

As of today, US Patent 10,541,279 has not had any of its claims canceled or sustained by the PTAB. The single IPR filed against it, IPR2025-01476, was terminated due to a settlement. Consequently, all claims of the patent remain untested by the PTAB and are considered to be in their originally granted state.

Regarding estoppel, since IPR2025-01476 was terminated via settlement and no institution decision or Final Written Decision was issued, the statutory estoppel provisions of § 315(e)(2) for grounds raised or that reasonably could have been raised are not applicable. This means that future petitioners are not estopped from challenging the patent based on prior art that could have been raised in IPR2025-01476.

The pattern signal indicates that there has been one challenge to this patent through the PTAB process, initiated by BOE Technology Group Co., Ltd. et al. The settlement suggests a resolution outside of a full PTAB trial. Unified Patents, a defensive aggregator, is listed as a petitioner in the Unified Patents PTAB Data, indicating their involvement in challenging the patent.

Recommended next steps

Since there are no active PTAB proceedings and no claims have been invalidated, a defendant facing assertion of this patent would need to conduct their own validity analysis to determine the strength of a potential IPR challenge. The absence of a litigated IPR to a final decision means that any new IPR petition would effectively be the first substantive review of the patent's claims by the PTAB.
