In Daniels, et al., v. The Walt Disney Company, et al., the Ninth Circuit held that The Moodsters, characters representing emotions, created by Daniels, were not "sufficiently delineated" to be eligible for copyright protection, because the characters in The Moodsters changed their shape and personality throughout the movie. Therefore, Disney was not found liable for copyright infringement for the use of characters that represented emotions in its Pixar movie “Inside Out”.
