PTAB challenges

Proceedings overview

One AIA trial proceeding has been filed against US10832616, which was terminated due to settlement. This means the patent's claims were not adjudicated by the PTAB, and thus, no claims were invalidated by a Final Written Decision. This gives a defendant less clarity on the patent's validity from a PTAB perspective, as the claims remain untested by a full IPR trial.

IPR2025-01544 — BOE Technology Group Co., Ltd. v. Samsung Display Co., Ltd.

• Type: Inter Partes Review
• Filed: 2025-09-23
• Status: Terminated-Settled – The proceeding was concluded due to an agreement between the petitioner and the patent owner, rather than a full adjudication by the Patent Trial and Appeal Board.
• Judge panel: Information regarding the specific judge panel for this IPR is not publicly available at this time.
• Petition grounds: Details regarding the specific claims challenged, the prior art asserted, and the statutory bases (§ 102 / § 103 / § 112) of the petition are not publicly available due to the settlement and early termination of the proceeding.
• Institution decision: An institution decision was not publicly issued before the proceeding was terminated by settlement.
• Final Written Decision: No Final Written Decision was issued as the proceeding was terminated due to settlement.
• Settlement / termination: The proceeding was terminated as Terminated-Settled, with the last modification recorded on 2026-05-22. 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: Since this IPR was terminated by settlement and no claims were adjudicated, the patent claims of US10832616 have not been formally validated or invalidated by the PTAB. This means a defendant facing assertion of this patent will need to evaluate the claims based on their own prior art analysis, without the benefit of a PTAB decision on validity.

Strategic summary

As of today, US10832616 has been subject to one IPR proceeding, IPR2025-01544, which was initiated by BOE Technology Group Co., Ltd. This proceeding concluded in a settlement between the parties on 2026-05-22, and as such, no claims of the patent have been formally canceled or sustained by a Final Written Decision from the PTAB. Consequently, all claims of US10832616 remain legally patentable as far as PTAB proceedings are concerned. The patent is effectively "untested" in the context of a full IPR trial with a final validity determination.

The estoppel landscape for IPR2025-01544 is limited due to the settlement. Under 35 U.S.C. § 315(e)(1), if an IPR is instituted and leads to a final written decision, the petitioner and its real parties in interest are estopped from asserting in a civil action or another USPTO proceeding that a claim is invalid on any ground that the petitioner raised or reasonably could have raised during the IPR. However, for a terminated-settled proceeding, the Federal Circuit has held that estoppel under § 315(e)(1) does not apply because there is no Final Written Decision. Therefore, the petitioner, BOE Technology Group Co., Ltd., and its privies may not be estopped from raising the same or similar prior-art grounds in future proceedings, depending on the specific terms of their confidential settlement agreement. For other potential defendants, all prior-art grounds remain available.

There is no clear pattern of aggressive PTAB appeals by the patent owner or multiple IPRs from the same petitioner based on this single, settled proceeding. While Unified Patents is sometimes involved in IPRs against Samsung Display, the official petitioner of record for IPR2025-01544 as provided in the canonical data is BOE Technology Group Co., Ltd.

Recommended next steps

Since IPR2025-01544 was terminated by settlement and no claims were invalidated, any defendant facing assertion of US10832616 should conduct a thorough independent invalidity analysis. The absence of a PTAB Final Written Decision means there is no public record of the claims being tested on their merits in an IPR setting. It would be prudent to investigate the details surrounding the settlement of IPR2025-01544, if possible, to understand the context, although the terms are likely confidential. This patent has not been hardened through IPR, leaving potential avenues for a new petitioner.
