PTAB challenges

Proceedings overview

Only one AIA trial proceeding, IPR2025-01329, has been filed against US patent 7769238. This proceeding was terminated due to settlement before a decision on institution was reached. This means no claims of US7769238 have been challenged on their merits at the PTAB, leaving the patent's claims entirely untested by AIA trial proceedings. For a defendant, this means the patent has not been "hardened" by surviving IPRs, but also that no claims have been invalidated by the PTAB.

IPR2025-01329 — Hisense USA Corporation et al. v. VIDEOLABS Inc.

• Type: Inter Partes Review
• Filed: 2025-07-25
• Status: Terminated-Settled. The parties reached a settlement agreement, leading to the termination of the proceeding before a decision on institution.
• Judge panel: Not applicable, as the proceeding was terminated before institution.
• Petition grounds: Information not publicly available due to termination prior to institution.
• Institution decision: Denied (implicitly, due to termination before institution decision deadline). The proceeding was terminated on 2026-01-27, which is within the typical 6-month statutory period for an institution decision. The settlement resulted in the proceeding's termination.
• Final Written Decision: Not issued. The proceeding settled before reaching this stage.
• Settlement / termination: The proceeding was terminated on 2026-01-27 due to settlement between Hisense USA Corporation and VIDEOLABS Inc. The specific terms of the settlement are confidential.
• Appeal: No appeal was filed, as no Final Written Decision was issued.
• Defensive value: This IPR had no impact on the validity of the patent's claims, as it was settled and terminated before institution. This means the patent owner, VIDEOLABS Inc., did not have to defend the claims on their merits at the PTAB in this instance. For a new defendant, the claims of US7769238 remain untested by this IPR.

Strategic summary

As of today, US patent 7769238 has all its claims (claims 1-20)

• SUSTAINED: No claims have been sustained by the PTAB.
• CANCELED: No claims have been canceled by the PTAB.
• UNTESTED: All claims of US7769238 remain untested by AIA trial proceedings, as the sole IPR filed against it (IPR2025-01329) was terminated due to settlement before an institution decision was rendered.

Estoppel landscape: Since IPR2025-01329 was terminated by settlement before institution, the petitioner (Hisense USA Corporation et al.) and their privies are not subject to the statutory estoppel provisions of 35 U.S.C. § 315(e)(2). This means that Hisense, or any party in privity with them, would not be barred from raising the same or similar prior art grounds in future litigation or PTAB proceedings if they chose to do so. For other defendants, all prior-art grounds remain available for challenge.

Pattern signals: The single IPR filing by Hisense USA Corporation et al. indicates that at least one entity found grounds to challenge the patent. The settlement before institution suggests that the parties resolved their dispute without the PTAB ruling on the merits of the patentability challenge. It is worth noting that Unified Patents has filed other IPRs related to this patent family, such as IPR2022-00628 and IPR2018-00658, which were not instituted. This suggests a history of attempts to challenge the patent by defensive aggregators.

Recommended next steps

• Since no PTAB activity resulted in claim invalidation, a defendant facing assertion of US7769238 would need to consider a fresh challenge to the patent's claims. Given the previous attempts by Unified Patents that were not instituted, a careful analysis of prior art and petition grounds would be crucial for any new IPR filing.
• The legal status of the patent indicates it "Expired - Lifetime" on 2024-08-16. This means the patent is no longer enforceable for future acts of infringement. However, past infringement (prior to 2024-08-16) could still be asserted. This significantly alters the landscape for any potential defendant, as remedies for future infringement are moot.
• Given the patent's expired status, any new PTAB proceeding would likely be focused on past damages, if applicable. The value proposition of filing a new IPR would need to be carefully weighed against the cost, especially considering the patent's expiration.
• It would be advisable for a defendant to conduct a thorough prior art search to assess the patentability of the claims independently, especially if facing accusations of past infringement.
