PTAB challenges

Proceedings overview

There is one AIA trial proceeding on file for US Patent 10482517. The proceeding, IPR2025-01144, was terminated due to settlement. As no claims were invalidated, the patent remains undiminished by PTAB challenges thus far, which slightly hardens the defensive posture for a defendant.

IPR2025-01144 — Perfect Corporation v. Zugara Inc.

• Filed: 2025-06-26
• Status: Terminated-Settled
• Judge panel: Not publicly available from the provided information.
• Petition grounds: Not publicly available from the provided information.
• Institution decision: Not publicly available from the provided information as the case was terminated-settled before a decision on 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 settled on 2026-02-03. The specific terms of the settlement are confidential.
• Appeal: Not applicable, as no Final Written Decision was issued.
• Defensive value: This IPR was terminated due to settlement, meaning no claims of US10482517 were challenged to a final decision. This implies that the patent claims have not been subjected to a full PTAB review of patentability, so prior art grounds remain available for potential future challenges.

Strategic summary

All claims of US10482517 remain UNTESTED by a full PTAB trial. The single IPR filed, IPR2025-01144, was terminated due to settlement before an institution decision or Final Written Decision, meaning no claims were canceled or sustained through the PTAB process.

The estoppel landscape for this patent is unaffected by IPR2025-01144 because the proceeding settled. As there was no institution decision, 35 U.S.C. § 315(e)(2) estoppel, which bars petitioners and their privies from asserting grounds raised or that reasonably could have been raised in an IPR, would not apply. Therefore, all prior-art grounds are still available for a defendant currently facing assertion of this patent.

The settlement of IPR2025-01144 with Perfect Corporation, without reaching an institution decision or Final Written Decision, indicates a private resolution between the parties rather than a public determination of the patent's validity. While the petitioner was Perfect Corporation, the settlement prevents any public insight into the strength of the invalidity arguments they might have presented.

Recommended next steps

As there is no Final Written Decision invalidating claims, a defendant facing assertion of US10482517 would need to develop their own prior art invalidity arguments. If considering a new PTAB challenge, it would be prudent to review the IPR petition from IPR2025-01144 (if publicly accessible through a PACER search or other means, as the USPTO PTAB E2E portal link for settlement notices is often for the notice itself, not the petition content) to understand the prior art and arguments previously considered by Perfect Corporation, even though no estoppel applies. There are no active PTAB proceedings currently pending for this patent. The absence of a completed PTAB trial means the patent has not been subjected to the scrutiny of the PTAB process, which could be an opportunity or a challenge depending on the strength of available prior art.
