The Deadmau5 vs. Disney battle of 2014 has just escalated. A day after the corporate media giant filed a 171-page trademark opposition against Deadmau5 for his famed headgear, the Niagara Falls-born entertainer – real name: Joel Zimmerman – had his lawyer send a cease and desist letter to the company. The letter alleges Disney uses one of his most popular tracks, Ghosts ‘n Stuff, for an animated clip on its website without his permission. The video features about 90 seconds of Zimmerman’s music to accompany clips of old Mickey Mouse animation, for a short called Re-Micks. “We just hit them back pretty hard,” Zimmerman told The Review late Thursday. “They’ve been infringing on my rights the whole time.” Zimmerman scanned both pages of the cease and desist and posted it on his Twitter page. “Oh, @disney just in case you don’t check your e-mail, I’ll just leave this here,” he wrote. He later added: “It takes ‘em 10 years to oppose a trademark, let’s see how long it takes ‘em to take down a video.” Not long, apparently. The link Zimmerman attached in his tweet was inactive by Friday, redirecting to the DisneyParks.ca home page. The cease and desist letter, drafted by Zimmerman’s L.A.-based attorney Dina LaPolt, says Zimmerman was under contract with EMI Music Publishing when he composed the track, and is “unaware of any licenses(s) between Disney and EMI…granting Disney the right to synchronize the Composition with the Infringing Video” or exploit the master recording “in any manner or media.” On Wednesday, the company made a move to block Zimmerman from trademarking his familiar Mau5 head in the U.S., a prominent part of his music and branding since his first album in 2005. Disney claims the image is too similar to its iconic mascot Mickey Mouse, who first appeared in the 1928 animated short Steamboat Willie. Zimmerman applied through the U.S. Patent and Trademark Office last year. He already owns the Mau5 Head image in 30 other countries. As part of its opposition, Disney contends it “owns long-standing rights in its mouse ears mark,” and that Zimmerman’s mau5head will create confusion. “Disney doesn’t want me to file in the U.S. for some weird reason,” Zimmerman told The Review. “”(I’m) trying to set up a jousting match in the Magic Kingdom to settle the matter.” In a written statement to media, LaPolt wonders why Disney is “only now coming after Deadmau5,” since the electronic music producer has been using the mau5head “in the U.S. and around the world” for nearly a decade. “Our client will not be bullied by Disney and is prepared to fight to protect his rights to his property.” Disney responded late Friday with a statement e-mailed to The Review: “Disney vigorously protects its trademark rights, and we oppose Mr. Zimmerman’s attempt to register a logo that is nearly identical to our trademarks for his commercial exploitation,” wrote a spokesperson. “Our opposition is not about the use of the Deadmau5 costume. The music was appropriately licensed, and there is no merit to his statement.” It’s not the first time a Niagara native has squared off against Disney. In 2000, Fonthill architect Edward Russell and business partner Nicholas Stracick of Buffalo negotiated an undisclosed settlement after a Florida jury awarded them $240 million based on a finding the company used their design for a Wide World of Sports park. The 200-acre facility opened in 1997, a decade after the idea was pitched to Disney officials.
