PTAB challenges

Proceedings overview

There is one AIA trial proceeding on file for US Patent 9727655. This proceeding, IPR2025-01327, was terminated before a Final Written Decision was issued, meaning no claims of the patent were invalidated or sustained by the Patent Trial and Appeal Board (PTAB). This leaves the patent's claims formally untested by a PTAB validity determination. From a defensive posture, a defendant facing assertion of this patent will find its claims currently intact in the eyes of the PTAB.

IPR2025-01327 — Reolink Innovation Inc. et al. v. THROUGHTEK TECHNOLOGY (SHENZHEN) Co Ltd

• Type: Inter Partes Review
• Filed: 2025-07-18
• Status: Terminated. This indicates the proceeding ended before a Final Written Decision was rendered by the PTAB. The exact reason for termination (e.g., settlement between parties, voluntary withdrawal of the petition, or a discretionary denial by the Director before institution) is not detailed in the publicly available search results. The last modification date was 2026-05-19.
• Judge panel: Information regarding the specific Administrative Patent Judges assigned to the panel for this proceeding is not publicly available from the provided search results.
• Petition grounds: The specific claims challenged, prior art references asserted, and statutory bases (§ 102 / § 103 / § 112) for the petition are not publicly available from the provided search results.
• Institution decision: Details regarding whether the petition was instituted, denied, or partially instituted, including the date of the decision and any reasoning by the panel or Director, are not publicly available from the provided search results. Given the "Terminated" status, it is possible the proceeding was terminated prior to a formal institution decision being issued or published.
• Final Written Decision: A Final Written Decision was not issued for this proceeding due to its termination.
• Settlement / termination: The proceeding was terminated, with the last modification date being 2026-05-19. If the termination was due to a settlement, the specific terms would typically be confidential and are not publicly available.
• Appeal: There was no appeal to the Federal Circuit, as the proceeding was terminated before a Final Written Decision.
• Defensive value: Since this IPR was terminated without a Final Written Decision, it did not result in any claims being invalidated or confirmed as patentable by the PTAB. Consequently, the patent's validity, specifically the patentability of its claims under IPR review standards, remains formally untested by a PTAB trial. For a defendant, this means the patent claims are currently presumed valid in the context of PTAB proceedings.

Strategic summary

All claims of US9727655 remain UNTESTED by a PTAB Final Written Decision. The single IPR filed, IPR2025-01327, was terminated prior to reaching a final judgment on the merits of the challenged claims. Therefore, there has been no narrowing of the patent through IPR, and all claims are currently considered enforceable from a PTAB perspective.

Regarding the estoppel landscape, since IPR2025-01327 was terminated without a Final Written Decision, the statutory estoppel provisions of 35 U.S.C. § 315(e)(2) against the petitioner (Reolink Innovation Inc. et al.) and their privies would not apply for any grounds that were raised or reasonably could have been raised. This means that, in principle, the prior-art grounds that could have been asserted in this IPR remain available for future challenges by other parties (or potentially even Reolink in a different context if estoppel is not triggered by the termination reason itself).

There is only one PTAB proceeding on this patent, IPR2025-01327, filed by Reolink Innovation Inc. et al. The termination of the proceeding without a Final Written Decision is a notable signal. While the specific reason is not public, possibilities include a settlement between the parties or a discretionary denial by the USPTO Director (especially given increased Director involvement in institution decisions around late 2025 and early 2026). The termination implies the petitioner did not achieve a claims invalidation, leaving the patent owner in a relatively strong position concerning PTAB-related validity challenges so far.

Recommended next steps

Given that IPR2025-01327 was terminated without a Final Written Decision, no claims of US9727655 were invalidated by the PTAB. Therefore, there is no Final Written Decision to link to or quote for claim invalidation.

For a defendant facing assertion of this patent, the absence of an adverse PTAB ruling means the patent claims have not been weakened in this forum. However, the termination of the IPR could imply a confidential settlement, which might indicate some underlying strength of the patent or a strategic decision by the petitioner. Alternatively, it could have been a discretionary denial, which, depending on the reason (e.g., Fintiv factors), could make future IPR challenges more difficult.

Further investigation into the precise reason for the termination of IPR2025-01327 (e.g., through a review of the PTAB docket if available via subscription services or PACER if related to district court litigation) would be highly recommended to understand the context and potential strategic implications for future defensive actions.
