Jumbo Technology, a gaming equipment manufacturer from Taiwan, has initiated a lawsuit regarding patent infringement against a well-known live casino company. The claim states that Lightning-branded games are utilizing Jumbo’s special “dynamic raised odds” innovation. On May 29, in the US District Court for the District of Delaware, Jumbo filed its complaint and accused Evolution of breaking US Patent No. 9,646,459, which was given in 2017. This patent covers a system in which games such as roulette, baccarat, and dice are assigned random bonus odds.

In their letter, Jumbo’s legal team explained how the patented idea helps players stay more engaged, play for longer, and enjoy games that shift from basic and fixed to lively and unpredictable. When discussing online gambling, lawyers noted that dynamic raised odds make classic games much more thrilling and unexpected. This feature, according to Jumbo, works by giving players an occasional chance at higher payouts while still allowing casino operators to continue making money.

Jumbo Sues Evolution over Alleged Patent Infringement in Popular Live Casino Games

Jumbo also mentions that they hold the patent rights for this game feature. Since 200, this Taiwanese company has supplied the Asian gaming industry and insists its patented invention supports many best-selling games from the live casino giant. There are games like Lightning Roulette, Red Door Roulette, Lightning Baccarat, and Lightning Dice, and each offers random multipliers that boost how much players can win on some bets.

Back in June 2024, Jumbo said it warned Evolution about possible patent infringement and offered a patent license at a fair royalty price. From the claim, it appears both sides exchanged some messages, but Evolution decided against a license and kept operating the games throughout US states such as Delaware, West Virginia, Pennsylvania, New Jersey, and Michigan.

According to the lawsuit, Evolution’s infringement has been “wilful, deliberate, and intentional,” as it continued to use the patent despite being aware of it. Due to this situation, Jumbo now seeks damages, additional compensation for the wilfulness, and also requests that their lawyers’ fees be covered. One example in the complaint is a roulette game, where a payout that usually pays 35:1 could be raised to 42:1 using the patent’s technology.

There are also similar payout increases in baccarat and sic bo, where different multipliers are linked to certain bets and are adjusted based on probability so the casino’s advantage stays intact. Jumbo’s filing further claims that Evolution committed indirect infringement by inducing others, including licensed US casinos and game operators, to offer these disputed games to players.

The company also believes Evolution showcased Lightning games at events like G2E Las Vegas, aiming to capture US market attention. This court case is the latest legal battle for Jumbo in the United States, following another patent dispute with Light & Wonder. So far, Evolution has not made any official reply to this case in the court record. Lastly, NEXT.io has contacted them for a statement.
