Back in April, a trademark dispute between Deadmau5 and Disney began. Earlier this week, Deadmau5 said on twitter that he had received word that Disney filed suit opposition of his trademark, the dead mouse head. Deadmau5's response was of course, typical:

Disney thinks you might confuse an established electronic musician / performer with a cartoon mouse. That's how stupid they think you are. — deadmau5 (@deadmau5) September 3, 2014

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

Of course, you can't really blame him for the hostility. As you'll read in the documents below, Deadmau5's lawyer Dina LaPolt then responded by sending Disney a letter stating that Disney has violated Deadmau5's intellectual property by uploading their cartoon video entitled “Ghosts ‘n' Stuff – Re-Micks.” Deadmau5 says that the song “Ghosts ‘n' Stuff” that was used in their cartoon is an exclusive track for EMI Music Publishing Limited (“EMI”) which does not have any ties with Disney, and that they have never been granted permission to use.
