Cygames Reaches Settlement with Konami in 2023 Lawsuit Over Uma Musume: Pretty Derby

Konami vs. Cygames: What sparked the Uma Musume patent clash

The Japanese game maker Cygames says it has settled a patent case with Konami over Uma Musume: Pretty Derby. The clash began with a claim filed in March 2023. Konami sought a stop to distribution and damages that could total about 4 billion yen, roughly $29 million. The core argument centered on a training system where story events bend under the influence of support characters. Konami said this approach falls under its Japanese Patent No. 5814300.

The heart of the dispute

Konami pressed for an injunction that would pause the game’s release. It also asked for a large monetary penalty. The charge focused on a training feature tied to how characters help shape the tale. In short, Konami claimed the method was covered by its patent. Cygames disputed the claim and defended the tech behind Uma Musume’s growth mechanics.

Settlement details and what it means for players

On November 7, 2025, Cygames’ parent company announced a deal with Konami. The company said there was no admission of fault. The terms of the settlement remain confidential. The deal lets Uma Musume: Pretty Derby keep running without public legal worries. This removes the risk of a sudden service halt and lets fans play without interruption.

Why this matters in mobile game design

The case shines a light on how game systems use characters and story beats. If a training loop ties to how you use support characters, patents can come into play. Developers must balance creative ideas with legal checks. For players, the news offers reassurance that Uma Musume will stay online and evolving. For the wider scene, it’s a reminder that digital games sit near the edge of patent law.

Context around Uma Musume and the IP climate

Uma Musume is known for its mix of racing and storytelling. Players follow horse-girl racers and their daily journeys. The game blends character growth with race events, a combo some see as a key feature. The patent talk centers on how in-game events respond to in-game allies. Patent disputes like this show how tech rules touch live service games. The outcome can set a tone for other studios facing similar battles.

What this settlement means going forward

With the legal cloud cleared, the road ahead looks steady for Uma Musume. Cygames can keep updating the game without a looming injunction. Konami gains certainty about the future, even if the exact terms stay private. The broader effect is a clearer path for ongoing service and content drops. Fans can expect more races, stories, and character moments without legal fear.

Looking at the bigger picture

This resolution matters beyond one title. It shows how patents intersect with live games and ongoing updates. It also highlights how big firms handle disagreements in the gaming world. The move may nudge other makers to review their own training and story systems. It’s a sign that patent risk sits in many creative corners of mobile play.

Final thoughts for fans and developers

For players, Uma Musume: Pretty Derby remains a lively ride. The game keeps its focus on racing culture and character tales. For creators, the case underscores the need for clear ideas and strong protection of genuine innovations. The settlement lowers the chance of a lengthy legal pause and keeps the game’s momentum intact.
