Castle Rock Entertainment, Inc. v. Carol Publishing Group Inc. · US Court of Appeals, 2nd Circuit · 1998

Does the trivia book infringe?

Short answer: Yes: it took from the show.

The facts. A fan wrote a trivia book of 643 questions about Seinfeld, from character names to tiny plot details. The show's owner sued. The author said trivia is just facts, and that this was a harmless fan tribute.

The ruling. Castle Rock v. Carol Publishing (1998): The court held the book infringed, because the 'facts' were invented by the show's writers, and the book was not a fair use.

The book was called The Seinfeld Aptitude Test. The publisher was ordered to destroy its unsold copies. The court noted the quiz did nothing to transform the show.
