PTAB challenges

Proceedings overview

There is one AIA trial proceeding on file for US patent 10412141, which has been terminated. This means the claims of the patent have not been substantively challenged and deemed unpatentable by a Final Written Decision at the PTAB, thus leaving the patent's claims untested by the PTAB.

IPR2025-01222 — Amazon.com, Inc. et al. v. Divx LLC

• Type: Inter Partes Review
• Filed: 2025-06-30
• Status: Terminated (2025-10-21). The proceeding was procedurally terminated, meaning it did not reach a final merits decision on patentability.
• Judge panel: Information regarding the specific judge panel for this terminated proceeding is not readily available in public records without access to the full PTAB docket.
• Petition grounds: The detailed petition grounds, including specific claims challenged, prior art, and statutory bases (§ 102 / § 103 / § 112), are not publicly available due to the procedural termination.
• Institution decision: This proceeding was terminated before an institution decision was rendered.
• Final Written Decision: No Final Written Decision was issued as the proceeding was terminated procedurally.
• Settlement / termination: The proceeding was terminated on 2025-10-21, as a "Procedural Termination." The specific terms of termination (e.g., settlement, dismissal) are not publicly disclosed, but such a termination typically indicates that the parties resolved the matter before a substantive decision on the merits.
• Appeal: No appeal to the Federal Circuit was filed, as there was no Final Written Decision from the PTAB to appeal.
• Defensive value: This proceeding offers no direct defensive value in terms of claims being invalidated. The claims of US10412141 remain untested by a PTAB Final Written Decision. However, the fact that Amazon.com, Inc. et al. filed the IPR indicates a potential interest from an operating company in challenging the patent, and the termination suggests a resolution was reached outside of a PTAB decision on the merits.

Strategic summary

All claims of US10412141 remain untested by a Final Written Decision from the PTAB. The single IPR filed, IPR2025-01222, was procedurally terminated before institution, meaning no claims were canceled or sustained through the PTAB process. Consequently, a defendant facing assertion of this patent today does not have the benefit of any claims being invalidated by the PTAB.

The estoppel landscape for IPR2025-01222 is limited. Since the proceeding was terminated before institution and no Final Written Decision was issued, the statutory estoppel provisions under 35 U.S.C. § 315(e)(2) likely do not apply to the petitioner (Amazon.com, Inc. et al.) or their privies regarding the grounds that could have been raised. This means that, in principle, the prior-art grounds originally presented in the petition could potentially still be asserted in district court litigation or another PTAB proceeding (if applicable rules allowed).

A pattern signal is the petitioner, Amazon.com, Inc. et al., which suggests a defensive move against the patent. The fact that the proceeding was terminated indicates a resolution between the parties, which could involve a confidential settlement or license agreement.

Recommended next steps

Since there are no invalidated claims from the PTAB, any defendant facing assertion of US10412141 will need to develop their own invalidity arguments. There are no active proceedings with upcoming trial-stage milestones. The absence of a Final Written Decision means the patent's claims have not been formally tested for patentability at the PTAB.
