Jumbo Technology Sues Evolution Over Alleged Patent Infringement

In a high-profile legal move, Taiwanese gaming supplier Jumbo Technology has filed a patent infringement lawsuit against Evolution Gaming, the global leader in live casino content. The lawsuit, filed on May 29 in the U.S. District Court for the District of Delaware, alleges that Evolution’s popular Lightning-branded games use patented technology owned by Jumbo without permission.

Dispute Centers Around “Dynamic Raised Odds” Patent

At the core of the lawsuit is U.S. Patent No. 9,646,459, granted to Jumbo in 2017. The patent covers a system that dynamically enhances odds in games such as online roulette, baccarat, and dice. According to the filing, Evolution’s Lightning Roulette, Lightning Baccarat, Lightning Dice, and Red Door Roulette all feature a version of this mechanic, introducing random multipliers that increase certain payouts.

Jumbo claims this patented feature not only increases player engagement by boosting excitement and unpredictability but also helps operators maintain profitability, making it a crucial innovation in modern game design.

Licensing Talks Collapsed Before Legal Action

The lawsuit reveals that Jumbo first contacted Evolution in June 2024, offering to license the patented system on reasonable royalty terms. However, Evolution allegedly declined to engage in licensing discussions and continued deploying the contested games across regulated U.S. markets, including New Jersey, Pennsylvania, Michigan, Delaware, and West Virginia.

Jumbo accuses Evolution of willful and deliberate infringement, noting that the company had prior knowledge of the patent but chose to ignore it. The complaint also includes claims of indirect infringement, stating that Evolution encouraged third-party casinos to offer the games and promoted them at major industry events, such as G2E Las Vegas.

Seeking Damages and Enhanced Compensation

Jumbo is asking the court to award damages and additional compensation due to the willfulness of the alleged infringement, as well as legal fees. The lawsuit outlines how Evolution’s game mechanics allow roulette payouts to increase from 35:1 to as high as 119:1, similar to those used in Jumbo’s J-Multi Roulette terminals.

Background and Industry Impact

Founded in 2000, Jumbo Technology is a well-established supplier in the Asian casino market, known for integrating patented features into electronic table games. The company’s legal filing marks its latest attempt to defend intellectual property, following similar action against other gaming giants like Light & Wonder.

This isn’t Evolution’s first patent-related courtroom battle. The company previously filed suit against Light & Wonder in 2024 over a competing multiplier roulette game, only for the court to dismiss Evolution’s claims as covering abstract ideas rather than patentable innovation. That precedent may now play a role in the outcome of Jumbo’s case.

Whether Jumbo’s claims hold up in court remains to be seen, but the lawsuit underscores the increasing legal complexity surrounding game mechanics in the competitive live casino space.
