Step-by-step explanation:
In 1931, Walt Disney accused Van Beuren Studios of plagiarizing his character Mickey Mouse and obtained a temporary court injunction against them. This action was part of broader legal efforts to protect intellectual property and copyright within the growing film industry. The controversy emerged when Van Beuren released a series of cartoons featuring characters that were strikingly similar to Disney's iconic Mickey Mouse, leading to Disney taking legal action to defend his creations.
