IPR2025-01545 — BOE Technology Group Co., Ltd. v. Samsung Display Co Ltd

• Type: Inter Partes Review
• Filed: 2025-09-23
• Status: Terminated-Settled. The proceeding concluded due to a settlement between the parties.
• Judge panel: Information regarding the specific judge panel for this IPR is not publicly available in the provided patent details or general PTAB search results at this stage.
• Petition grounds: The exact claims challenged, specific prior art, and statutory bases (§ 102 / § 103 / § 112) for the petition are not publicly available due to the settlement and lack of an institution decision or full FWD record in the provided information.
• Institution decision: Not applicable or not publicly available. Given the "Terminated-Settled" status, it is likely the case settled before or shortly after the institution decision deadline, or the institution decision was never publicly issued as a final order.
• Final Written Decision: Not issued. The proceeding was terminated due to settlement.
• Settlement / termination: The proceeding was terminated as settled on 2026-05-22. The specific terms of the settlement are confidential.
• Appeal: No Federal Circuit appeal occurred, as no Final Written Decision was issued.
• Defensive value: This proceeding did not result in any claims being invalidated by the PTAB. Therefore, the patent claims of US11626066 remain intact from a PTAB challenge perspective. A defendant would need to consider the grounds raised in the petition (if they become known) for potential estoppel, but the patent itself has not been narrowed by this IPR.

Strategic summary

All claims of US11626066 remain untested by a Final Written Decision from the PTAB. The sole IPR filed against this patent, IPR2025-01545, was terminated as settled between BOE Technology Group Co., Ltd. and Samsung Display Co Ltd. This means no claims were canceled or sustained by the PTAB.

Regarding estoppel, since the proceeding was settled and no final written decision was issued, the statutory estoppel provisions of § 315(e)(2) generally do not apply to the petitioner (BOE Technology Group Co., Ltd.) or its privies concerning any grounds that could have been raised. However, any contractual estoppel agreed to as part of the confidential settlement terms would apply to the petitioner. For other potential defendants, all prior-art grounds remain theoretically available for a new IPR challenge, assuming the one-year window from the date of service of an infringement complaint has not passed. The settlement indicates that the patent owner (Samsung Display Co Ltd) has engaged in litigation or licensing activities with BOE Technology Group Co., Ltd. that led to this resolution, but it does not intrinsically harden the patent against future PTAB challenges by unrelated parties.

Recommended next steps

• Since IPR2025-01545 was terminated as settled, no public Final Written Decision is available for review or citation.
• Given the patent's active status and the prior IPR settlement, potential defendants should assume the patent owner is actively enforcing this patent. It would be prudent to conduct a thorough prior art search and invalidity analysis to identify potential new grounds for an IPR or district court defense, as all claims remain patentable from a PTAB perspective.
• Monitor any ongoing district court litigation or new PTAB filings related to US11626066. The fact that a major display technology company like BOE filed an IPR suggests the patent is relevant in the industry.
