EDM producer and DJ deadmau5 has found himself in a legal trademark battle with Disney over his signature mouse ears look.

On Tuesday, Sept. 2, TMZ reports that Disney filed legal papers to try to stop deadmau5 (real name Joel Thomas Zimmerman) from obtaining a trademark in the U.S. for his mouse logo, claiming that his helmet is too similar to that of Disney's logo of featuring a silhouette of Mickey Mouse's head.

Zimmerman has successfully applied, and been granted, a trademark in other countries such as Japan, Germany, Italy and the U.K. The 33-year-old Canadian musician has been using his deadmau5 persona for over 10 years now at shows.

In the documents, Disney argues that Zimmerman's use of his giant mouse helmet may do damage to the Disney brand in the U.S.

The artist took to Twitter to express his thoughts on the validity of Disney's claims.
