Both have big ears. Both have big eyes and both have big smiles. But the one is a Disney character and the other one a world renowned EDM producer and DJ and now it seems that Deadmau5 and Disney are currently playing a game of mouse and mouse — at least when it comes to both brands' signature rodent silhouettes. MTV.com reports that Deadmau5 (a.k.a. Joel Zimmerman) has filed a trademark registration with the U.S. Trademark office, according to Billboard, seeking to put a lock on the image of his massive mouse head. Disney, the progenitors of yet another mouse, are apparently less than pleased. The entertainment empire has asked for, and been granted, 90 days to look into Deadmau5's claim and to file a notice of opposition.
