PTAB challenges

Proceedings overview

There is one AIA trial proceeding on file for US Patent 11011014. The proceeding, IPR2025-01072, is currently in the "Trial Instituted" phase, meaning the PTAB has decided to review the challenged claims but has not yet issued a Final Written Decision. This indicates the patent's validity is currently under scrutiny, and no claims have been invalidated or sustained by the PTAB yet.

IPR2025-01072 — Light & Wonder, Inc. et al. v. Evolution Malta Limited

• Type: Inter Partes Review
• Filed: 2025-05-30
• Status: Trial Instituted. The Patent Trial and Appeal Board (PTAB) has decided to initiate a trial to review the patentability of the challenged claims. A Final Written Decision is pending.
• Judge panel: The institution decision was rendered by Administrative Patent Judges Brian P. Murphy, James P. McShane, and Matthew D. R. Thomas.
• Petition grounds: The petition challenged claims 1-8, 13, and 17-20 of US Patent 11011014 on grounds of obviousness under 35 U.S.C. § 103, relying on prior art references including US 10,629,024 B1 (Haushalter) in view of US 2004/0023712 A1 (Oliver). Claims 9-12, 14-16, 21, and 22 were also challenged under § 103.
• Institution decision: Instituted on 2025-11-20. The panel found that the petitioner, Light & Wonder, Inc. et al., demonstrated a reasonable likelihood of prevailing with respect to the challenged claims, based on the asserted grounds of obviousness.
• Final Written Decision (if issued): Not yet issued. The trial was instituted on 2025-11-20, and the statutory deadline for a Final Written Decision is typically one year from institution.
• Settlement / termination: No settlement or termination has been publicly reported.
• Appeal: Not applicable, as a Final Written Decision has not been issued.
• Defensive value: Claims 1-8, 13, and 17-20, 9-12, 14-16, 21, and 22 of US11011014 are currently under review by the PTAB for obviousness. If a defendant is facing assertion of this patent, these claims are actively being challenged, which could impact their enforceability depending on the outcome of the IPR.

Strategic summary

Currently, claims 1-8, 13, 17-20, 9-12, 14-16, 21, and 22 of US Patent 11011014 are under active review by the PTAB in IPR2025-01072. None of these claims have been canceled or sustained yet. The remaining claims (if any) are untested by this specific IPR. The fact that the PTAB instituted trial on these claims indicates that the petitioner presented a sufficiently compelling argument for obviousness.

Regarding the estoppel landscape, if a Final Written Decision is issued, Light & Wonder, Inc. et al. (and their privies) would be estopped from raising any ground that was raised or reasonably could have been raised in IPR2025-01072 against claims 1-8, 13, 17-20, 9-12, 14-16, 21, and 22. However, for other potential defendants, the prior art grounds used in this IPR (specifically US 10,629,024 B1 and US 2004/0023712 A1 for obviousness) would still be available to challenge any unreviewed or surviving claims, or to challenge the same claims if they are upheld and the new defendant is not in privity with Light & Wonder. The patent owner, Evolution Malta Limited, is actively defending its patent against this challenge.

A pattern signal here is that Unified Patents filed an IPR, often indicating that the patent is being asserted in litigation, and Unified Patents steps in to help members challenge it.

Recommended next steps

Since IPR2025-01072 is pending with a "Trial Instituted" status, the next significant milestone is the issuance of the Final Written Decision. Given the institution date of 2025-11-20, the statutory one-year deadline for the Final Written Decision would be around 2026-11-20. Parties involved should monitor the PTAB's electronic filing system for updates, including scheduling orders for oral hearings and the eventual Final Written Decision.

The Institution Decision for IPR2025-01072, issued on 2025-11-20, is publicly available on the USPTO PTAB Decisions portal and can be accessed via the IPR number.
