The first trademarks by Walt Disney run out of copyright protection starting in 2024. This would have happened 20 years earlier had it not been for the "Mickey Mouse Protection Act of 1998" (as discussed here). For corporations, copyright lasts for 95 years from first release. (For individual creators/authors, copyright lasts for 70 years after the last author dies.)
