Aristocrat Wins Crucial Discovery Victory in Legal Dispute with Light & Wonder

Background of the Legal Dispute
Aristocrat, a prominent Australian slot machine developer, recently achieved an important procedural win in its ongoing lawsuit against Light & Wonder (L&W), a competing gaming technology firm. A court in Nevada has granted Aristocrat the right to access essential evidence relevant to the case. This evidence includes the mathematical models used in several game titles launched by L&W since 2021, which are central to the allegations in this legal battle.
Details of the Court’s Decision
The US District Court for the District of Nevada overturned an earlier ruling that had prevented Aristocrat from reviewing the mathematical frameworks behind L&W’s games. The prior decision had found that Aristocrat did not clearly specify which trade secrets it aimed to protect. However, the new court order found that Aristocrat sufficiently clarified its request, allowing further scrutiny of the underlying game mathematics which are critical to the unique design of slot machines.
Core Allegations in the Case
At the heart of the dispute, Aristocrat accuses Light & Wonder—formerly known as Scientific Games—of unlawfully using proprietary algorithms and design elements from Aristocrat’s popular “Dragon Link” and “Lightning Link” slot series. Aristocrat contends that this infringement began after one of its key game designers, Emma Charles, left Aristocrat to join L&W in 2021.
Aristocrat points to L&W’s “Dragon Train” game series, developed following Ms. Charles’ move, as bearing strong resemblances to its own games. The company has also criticized L&W for incomplete disclosures, including missing financial documents related to the Dragon Train development. Aristocrat argues that these omissions obstruct its ability to fully investigate whether its technology was improperly used or duplicated.
Positions of the Parties
Light & Wonder firmly denies these allegations, asserting that its game development processes are independent and that the discovery demands by Aristocrat represent an overreach. Despite accepting the court’s ruling, L&W expressed disappointment and emphasized that its games, with the exception of Dragon Train and Jewel of the Dragon, do not incorporate Aristocrat’s mathematical systems.
Based on expert analysis, no evidence has been found showing Aristocrat’s math being used in any commercially released games other than Dragon Train and Jewel of the Dragon.
Statement from Light & Wonder
Current Status and Future Outlook
The case is expanding as Aristocrat has recently claimed that another L&W game, developed by a separate studio, also violates its trade secrets. The ongoing discovery process will be pivotal in clarifying these new allegations and could significantly influence the course of the dispute.
Although the recent ruling is a key advancement for Aristocrat, no final resolution appears near. The fact discovery phase is set to continue until December 15, 2025, with expert testimony scheduled to conclude by March 2026. This timeline suggests that unless a settlement is reached promptly, the litigation may persist for several years further.
