Universal argued in Universal City Studios, Inc. v. RKO General, Inc. that King Kong's plot and characters are in the public domain and therefore they could freely use them in their remake of King Kong (the original being made by RKO Pictures). Then, in Universal City Studios, Inc. v. Nintendo Co., Ltd., they sued Nintendo claiming that Donkey Kong is too similar to their character King Kong. Nintendo was successfully defended by the lawyer John Kirby and named one of their characters in his honor. It was actually a trademark case, not copyright, but still pretty hypocritical.
