Developer and publisher Riot Game has filed a lawsuit against esports organisation Riot Squad over trademark infringement.

That's according to Polygon, which reports that the League of Legends maker is taking the pro-games firm to court in California, claiming that Riot Squad has "unfairly and unlawfully" used the 'Riot' name - often without 'Squad' - to piggyback off Riot Games' success.

The company has said it will be seeking compensation for damage done and that the esports organisation should not be allowed to use the 'Riot' name.

Riot Squad initially applied for the 'Riot Squad' and 'RS" trademarks, as well as for that of its logo (pictured), with American IP authority USPTO on June 24th, 2019.

"Through its conduct, Riot Squad has willfully created circumstances whereby members of the public are likely to be led to incorrectly believe that the goods offered by Riot Squad are authorised by, sponsored by, or affiliated with Riot, its well-known marks, and the products provided thereunder," lawyers for the League of Legends maker said in the lawsuit.

"The Court should enjoin any further use of the 'Riot' name by Riot Squad, and Riot should be compensated for the damage done to its brand as a result of Riot Squad’s conduct."

Riot Squad doesn't operate a League of Legends team, but is involved with esports for titles such as Counter-Strike: Global Offensive, Fortnite, Rainbow 6 Siege, Apex Legends, and Playerunknown’s Battlegrounds.
