Mouse v. Mouse

Introduction of the issue between Deadmau5 and Disney

Earlier this week, the trademark registration for Deadmau5 (AKA "dead mouse") was caught in a mouse trap with word of Disney sending in a letter to oppose the mark. Joel Zimmerman, electronic music DJ and owner of the stage name Deadmau5, instantly tweeted about the news saying that Mickey better “Lawyer up.” 

“landed home to some interesting news: looks like Disney officially just filed in opposition of my trademark... lawyer up mickey.”— deadmau5 (@deadmau5) September 3, 2014.

Deadmau5's response and Disney's argument

So why is this game of "mouse and mouse" in motion? According to Disney, Deadmau5's mark is too similar to their iconic, family friendly, Mickey Mouse. The issue is that two similar marks can potentially cause consumer confusion. Zimmerman stated via twitter that he did not think that Disney's argument will stand. 

“Disney thinks you might confuse an established electronic musician/performer with a cartoon mouse,” the EDM DJ tweeted. “That’s how stupid they think you are.” How ever this opposition plays out, Deadmau5 is ready to play hard ball. "Our client will not be bullied  by Disney and is prepared to fight to protect his rights to his property,” says Dina LaPolt, Deadmau5’s attorney.
