IPR2025-01478 — BOE Technology Group Co., Ltd. et al. v. Samsung Display Co Ltd

• Type: Inter Partes Review
• Filed: 2025-08-30
• Status: Terminated-Settled. The proceeding concluded due to a settlement between the petitioner and the patent owner before a final decision on the merits.
• Judge panel: Information not publicly available in the provided data or immediate search results for this case's termination status.
• Petition grounds: Details regarding specific claims challenged, prior art references, and statutory bases (§ 102 / § 103 / § 112) are not directly available from the provided data or quick search results for a settled case. Generally, IPRs challenge claims under § 102 and § 103.
• Institution decision: Institution decision details are not available as the case status is 'Terminated-Settled'. IPRs typically settle before or shortly after institution.
• Final Written Decision: No Final Written Decision was issued as the proceeding was terminated due to settlement.
• Settlement / termination: The proceeding was terminated as "Settlement" on 2026-01-06. The specific terms of the settlement are confidential between the parties involved.
• Appeal: No appeal to the Federal Circuit occurred as no Final Written Decision was rendered.
• Defensive value: This IPR did not result in any claims being invalidated or confirmed by the PTAB. Therefore, a defendant facing assertion of this patent cannot rely on this specific proceeding for a final adjudication of claim invalidity. The claims of the patent remain unexamined on the merits by the PTAB through this IPR.

Strategic summary

No claims of US11574990 have been formally canceled or sustained by the PTAB. The single IPR filed, IPR2025-01478, was terminated due to settlement. This means the claims of the patent remain untested on the merits by the PTAB, as no institution decision or Final Written Decision was reached.

Regarding the estoppel landscape, since IPR2025-01478 was terminated via settlement without a final written decision, statutory estoppel under 35 U.S.C. § 315(e)(2) does not apply to the petitioner (BOE Technology Group Co., Ltd. et al.) or their privies for this IPR. Therefore, the prior art grounds that could have been raised in this IPR might still be available in other venues or future proceedings for parties not involved in the settlement. There is no clear pattern of multiple IPRs by the same petitioner or aggressive PTAB appeals by the patent owner based on the single, settled proceeding. Unified Patents is listed as a petitioner, indicating a defensive aggregator's involvement.

Recommended next steps

Since IPR2025-01478 was terminated by settlement, there is no Final Written Decision to link to or quote. The patent claims remain unadjudicated by the PTAB.

As a defendant, it's important to understand the settlement terms (if available) of IPR2025-01478 to ensure no preclusive effects apply to your specific situation. The absence of a PTAB decision on the merits means that the validity of the claims has not been confirmed or denied through the IPR process. If you are facing an assertion, evaluating the patentability of the asserted claims against prior art would be a crucial next step, as the patent has not been "hardened" by surviving an IPR to a final written decision.## Proceedings overview
