Castle Rock Entertainment Inc. v. Carol Publishing Group, 150 F.3d 132, was a U.S. copyright infringement case involving the popular American sitcom Seinfeld. Some U.S. copyright law courses use the case to illustrate modern application of the fair use doctrine.

The decision is noteworthy for classifying Seinfeld trivia not as unprotected facts, but as protectable expression. The court also rejected the defendant's fair use defense finding that any transformative purpose possessed in the derivative work was "slight to non-existent" under the Supreme Court ruling in Campbell v. Acuff-Rose Music, Inc., 510 U.S. 569 (1994).

Supp. 1361, is a U.S. district court case about whether the operator of a computer bulletin board service ("BBS") and Internet access provider that allows that BBS to reach the Internet should be liable for copyright infringement committed by a subscriber of the BBS.

The district court of the Northern District of California concluded that RTC's claims of direct and vicarious infringement failed, but genuine issues of fact precluded summary judgment on contributory liability and fair use.
