Mickey and Minnie vs Milton and Mary:
Few cartoon characters are more recognizable around the world than Mickey Mouse and his girlfriend Minnie Mouse. This early copyright infringement case came just a few years after Mickey and Minnie Mouse had been copyrighted and trademarked. Walt Disney won his case against the creators of Mickey and Minnie look-a-likes Milton and Mary. The defendants, the Pathe Exchange and Van Beuren Corporation, were barred from ever using Milton or Mary in another animated film.
