Taiwanese gaming equipment supplier Jumbo Technology has initiated a patent infringement lawsuit against Evolution, alleging that Evolution’s popular Lightning-branded games unlawfully use its patented “dynamic raised odds” feature. This legal battle, filed on May 29, 2025, in the U.S. District Court for the District of Delaware, claims that Evolution’s games violate US Patent No. 9,646,459, a patent granted to Jumbo in 2017. The patent covers a system that randomly generates enhanced odds in games like roulette, baccarat, and dice, creating an exciting dynamic that increases player engagement.
Jumbo Technology’s Claims and the Patented Feature
Jumbo Technology asserts that its innovative system, designed to offer occasional boosted payouts, forms the backbone of several of Evolution’s flagship live casino games, including Lightning Roulette, Red Door Roulette, Lightning Baccarat, and Lightning Dice. These games incorporate random multipliers that elevate the payout potential on selected bets, with the goal of boosting player engagement and increasing excitement. According to Jumbo’s legal team, the innovation behind the dynamic raised odds system transforms static game formats into more unpredictable and thrilling experiences.
The lawsuit claims that this feature has revolutionized online gambling by making games more dynamic and less predictable, allowing players to enjoy the thrill of bigger payouts while still maintaining profitability for operators. Jumbo’s patent is intended to enhance the overall gaming experience by injecting a level of excitement that traditional, static models of gaming simply do not offer.
Jumbo’s Efforts to Resolve the Issue
Jumbo Technology reportedly contacted Evolution in June 2024, bringing attention to the potential patent infringement and offering to license the technology for a reasonable royalty fee. However, after a period of communication, Evolution allegedly refused to enter into licensing negotiations and continued to operate its games in several U.S. markets, including Delaware, West Virginia, Pennsylvania, New Jersey, and Michigan. Jumbo claims that Evolution’s refusal to engage in discussions regarding the patent led to the filing of this lawsuit, accusing Evolution of willfully and deliberately infringing on its patent.
Jumbo is seeking substantial damages, including enhanced compensation for the alleged willful infringement, as well as reimbursement for legal fees. The lawsuit also claims indirect infringement, accusing Evolution of encouraging third parties, such as licensed U.S. casinos and game operators, to offer its allegedly infringing games. This includes promoting the Lightning series at industry events such as G2E Las Vegas in an effort to drive adoption within the U.S. market.
Evolution’s Response and Legal Proceedings
As of now, Evolution has not yet issued a public response to the complaint filed by Jumbo Technology. The case is still in its early stages, and it remains to be seen how Evolution will defend against these claims. The outcome of this legal battle could have significant implications for Evolution, especially as it operates in key markets across the U.S. where its Lightning-branded games are highly popular.
The Impact on the Online Gambling Industry
The ongoing lawsuit highlights the increasing importance of patent protection in the rapidly expanding online gaming sector. With companies like Evolution continuing to innovate in live casino gaming, patent disputes over key features such as dynamic odds systems are likely to become more prevalent. This case also shows the challenges faced by game developers who must navigate the complexities of intellectual property rights in an increasingly competitive market.
