IPR2026-00051 — Disney Entertainment & Sports LLC v. Albert J. McGowan et al

• Type: Inter Partes Review
• Filed: 2025-10-31
• Status: Terminated
• Judge panel: [No specific judge panel information is publicly available for terminated cases without an institution decision or FWD.]
• Petition grounds: [The petition grounds are not publicly available due to the procedural termination before institution.]
• Institution decision: Denied (procedural termination before institution).
• Final Written Decision: Not applicable; the proceeding was terminated before a Final Written Decision could be issued.
• Settlement / termination: The PTAB case IPR2026-00051 was filed on October 31, 2025, and reached "Procedural Termination" by March 28, 2026. While the specific terms are not publicly disclosed, the outcome suggests a resolution between the parties prior to the institution of trial.
• Appeal: Not applicable; there was no Final Written Decision to appeal.
• Defensive value: The procedural termination of this IPR before institution means the patent owner effectively prevailed at this stage, and the patent claims remain unchallenged by this specific proceeding. This strengthens the patent owner's position against a defendant, as an IPR-based defense on the same grounds by the petitioner (or those in privity) would be barred by estoppel.

Strategic summary

Currently, all claims of US8280987 are SUSTAINED and UNTESTED by any IPR Final Written Decision. The single IPR filed, IPR2026-00051, was procedurally terminated before a decision on institution, meaning no claims were ever put at risk or invalidated in this proceeding.

Regarding the estoppel landscape, since IPR2026-00051 was terminated before institution, 35 U.S.C. § 315(e)(1) estoppel, which applies to grounds raised in a petition that results in a final written decision, would not apply. However, depending on the nature of the "procedural termination" and any underlying settlement, contractual estoppel might prevent Disney Entertainment & Sports LLC (the petitioner) and its privies from re-asserting the same prior art grounds. For a new defendant facing assertion of this patent, virtually all prior-art grounds remain available for a potential IPR challenge, as there has been no institution decision or FWD.

The procedural termination of IPR2026-00051, coupled with the active District Court litigation, suggests a potential settlement or agreement between Adeia and Disney related to this patent and possibly others. The fact that the IPR was terminated before institution indicates a swift resolution, at least concerning the IPR aspect, between these specific parties.

Recommended next steps

Given the procedural termination of IPR2026-00051, there is no FWD to link to or quote for claim invalidation. All claims of US828097 remain intact from a PTAB perspective.

If you are a defendant facing assertion of this patent and are not in privity with Disney Entertainment & Sports LLC, all prior art grounds are theoretically available to challenge the patent's validity via a new IPR petition. However, a thorough prior art search would be crucial to identify strong grounds. The ongoing District Court litigation (1:24-cv-01231 in Delaware) should be closely monitored for any developments or arguments related to validity or infringement that may arise.

No other PTAB activity for US8280987 has been found. The absence of additional IPRs or other AIA trials, especially given the ongoing litigation, could signal either a lack of strong prior art challenges or a strategic decision by other potential petitioners to await the outcome of the district court case.

• Judge panel: Information not publicly available for terminated cases without an institution decision or FWD.

• Institution decision: Denied (procedural termination before institution). The PTAB case IPR2026-00051 was procedurally terminated before a decision on institution was reached.

• Appeal: Not applicable; there was no Final Written Decision to appeal.
• Defensive value: The procedural termination of this IPR before institution means the patent owner successfully avoided a PTAB review of the patent's claims.

For a defendant, this means that the specific grounds raised by Disney Entertainment & Sports LLC in this IPR are likely estopped for them and their privies in future proceedings.
