It is understood that the intellectual property issues involved in Disney projects are very complex. Taking "Mickey Mouse" as an example, there are copyrights to the original image of Mickey Mouse, copyrights to Mickey Mouse film and television works, etc. At the same time, Disney has applied for trademark registration in 45 categories on the image of Mickey Mouse, and has more than a thousand valid registered trademarks in China. Different forms of intellectual property have different protection periods, scopes and methods. The Mickey Mouse cartoon image was born in 1928. According to the 1909 US Copyright Act, it can be protected by copyright for 56 years, which means it entered the public domain in 1984. In 1976, U.S. copyright law added an additional 19 years of protection, which expired on December 31, 2003. However, Disney’s intellectual property rights are authorized to be extended by Congress every year. It can be said that Disney’s intellectual property rights will never expire. China must protect them according to the intellectual property agreement with the United States
