Castle Rock Entertainment, Inc. v. Carol Publishing Group, Inc.
Facts
Castle Rock owned the copyrights in each episode of the Seinfeld television series. Defendants authored and published The Seinfeld Aptitude Test, a 132-page trivia book containing 643 questions and answers drawn from 84 of the 86 aired Seinfeld episodes, with every question and correct answer based on fictional moments from the show and 41 questions or answers containing Seinfeld dialogue. Golub created the book by taking notes from broadcasts and reviewing recorded episodes, and the book prominently used the name "Seinfeld" and images of principal actors. Castle Rock had licensed some Seinfeld-related products but had not authorized this trivia book.
Issue
Whether The Seinfeld Aptitude Test copied enough protected expression from Seinfeld to constitute actionable copyright infringement, and if so, whether the book's use of Seinfeld was nevertheless protected as fair use under 17 U.S.C. § 107.
Rule
Once actual copying is established, infringement requires substantial similarity to protected expression, meaning copying that is quantitatively more than de minimis and qualitatively directed at copyrightable expression rather than unprotectable ideas or facts. In fair use analysis, courts weigh the statutory factors in light of copyright's purposes, with special attention to whether the secondary work is transformative and whether it usurps a traditional or likely derivative market that the copyright owner would generally develop or license.
