Mickey Mouse's first movie Steamboat Willie entered the public domain in 2024. Now one of America's largest personal injury firms is suing Disney, reports the Associated Press, "in an effort to get a ruling that would allow it to use Steamboat Willie in advertisements..."[The law firm said] it had reached out to Disney to make sure the entertainment company wouldn't sue them if they used images from the animated film for their TV and online ads. Disney's lawyers responded by saying they didn't offer legal advice to third parties, according to the lawsuit. Morgan & Morgan said it was filing the lawsuit to get a decision because it otherwise feared being sued by Disney for trademark infringement if it used Steamboat Willie. "Without waiver of any of its rights, Disney will not provide such advice in response to your letter," Disney's attorneys wrote in their letter (adding "Very truly yours..."). A local newscast showed a glimpse of the letter, along with a few seconds of the ad (which ends with Minnie Mouse pulling out a cellphone to call for a lawyer...) Attorney John Morgan tells the newscast that Disney's legal team "is playing cute, and so we're just trying to get a yes or no answer.. They wrote us back a bunch of mumbo-jumbo that made no sense, didn't answer the question. We tried it again, they didn't answer the question..." (The newscast adds that the case isn't expected to go to court for at least a year.)Read more of this story at Slashdot.
