While the Brothers Grimm's original fairy tale "Snow White" is in the public domain, Disney owns the copyright to its specific 1937 animated film adaptation, including the character Snow White and other elements like the dwarfs' names.
The original Brothers Grimm fairy tale, published in 1812, is in the public domain, meaning it is not subject to copyright and anyone can freely adapt or use it.
Disney's 1937 animated film, "Snow White and the Seven Dwarfs," is a specific adaptation of the fairy tale, and Disney owns the copyright to that version
Disney also holds a trademark for the name "Snow White" for use in various entertainment contexts, including movies, television, and stage productions.
While Disney owns their version, others can create their own adaptations of the Snow White story, but they cannot infringe on Disney's specific elements like the dwarfs' names or the visual appearance of Snow White as depicted in the 1937 film.
