Jumbo Technology Takes Legal Action Against Evolution Over Alleged Patent Violation

Taiwanese gaming supplier Jumbo Technology has filed a patent infringement lawsuit against leading live casino developer Evolution, alleging that several of Evolution’s flagship Lightning-branded games use a patented feature without authorization. The complaint centers around Jumbo’s US Patent No. 9,646,459, which protects a system for dynamically generating enhanced odds in games like roulette, baccarat, and dice.

Dynamic Odds Feature at Heart of the Dispute

Filed on May 29 in the US District Court for the District of Delaware, the suit accuses Evolution of willfully infringing on Jumbo’s patent, which was granted in 2017. According to the legal filing, Evolution’s popular games—including Lightning Roulette, Lightning Baccarat, Lightning Dice, and Red Door Roulette—allegedly utilize the patented “dynamic raised odds” feature, which introduces randomly generated multipliers to selected bets.

Jumbo’s legal team emphasized that this technology represents a shift from conventional game mechanics. As stated in the court documents: “The result of the innovation claimed in the ‘459 Patent is that players are more engaged, play longer, and derive more enjoyment from a system that converts the standard, static game structure to an exciting, dynamic, and less predictable game.”

The company contends that the patented feature not only adds excitement by boosting payouts intermittently but also sustains operator profitability—making it a commercially valuable innovation in the online casino space.

Licensing Talks Rejected, Lawsuit Follows

According to the lawsuit, Jumbo first alerted Evolution in June 2024 about the possible patent infringement and extended an offer to license the technology on reasonable royalty terms. Despite initiating communication, Jumbo claims Evolution ultimately refused to enter into licensing negotiations and continued offering the contested games across several U.S. markets, including New Jersey, Michigan, Pennsylvania, Delaware, and West Virginia.

In the legal filing, the Taiwanese company alleges that Evolution’s actions were not only deliberate but also “wilful, deliberate, and intentional,” noting that the developer had actual knowledge of the patent yet chose to proceed without authorization.

Damages and Broader Claims of Infringement

Jumbo is now seeking a court ruling that awards damages, enhanced compensation due to the willfulness of the alleged infringement, and attorney’s fees. Among the specific examples cited are enhancements in roulette payouts, where traditional odds of 35:1 might be raised to 42:1 using the patented system. Comparable mechanics are described for baccarat and sic bo, where specific bet outcomes trigger variable multipliers, balanced to preserve the house edge.

The complaint also outlines indirect infringement, asserting that Evolution encouraged third-party operators—such as licensed U.S. casinos —to offer the infringing games. Furthermore, the suit points to marketing efforts at major trade shows, including G2E Las Vegas, as evidence of Evolution’s promotion of the contested content within the U.S. market.

At the time of publication, Evolution has not publicly responded to the complaint or commented on the allegations. This lawsuit adds to Jumbo Technology’s broader legal efforts, including other ongoing IP cases, such as one against Light & Wonder.
