Sega filed a lawsuit for 900 million yen ($11 million) against Level-5 claiming that Inazuma Eleven violates two patents owned by Sega.
After examining the discrepancies, Level-5 responded with a statement saying Inazuma Eleven does not infringe on Sega’s patents and Level-5 is prepared to fight their case in court.
The heart of the lawsuit is about the way you control characters using a stylus or a fingertip. Level-5 says nowadays using a stylus to move characters around is a fundamental control scheme. Level-5 reiterated that Inazuma Eleven does not infringe on any Sega patents and this lawsuit could restrict options for game developers and inhibit the growth of the game industry as a whole.
