In the case of United States v. Schneer's Atlanta, Inc., 1956, the Supreme Court dealt with a dispute over copyright infringement. The defendant, Schneer's Atlanta Inc., was accused of infringing on Columbia Pictures' copyrighted film "The 5000 Fingers of Dr.T" by showing it in their drive-in theater without obtaining proper licensing rights from Columbia Pictures. The District Court initially ruled in favor of Schneer’s Atlanta, stating that they were not directly responsible for the infringement as they had leased the film from an independent distributor and therefore did not have knowledge about any potential copyright issues. However, upon appeal to the Supreme Court by Columbia Pictures Corporation and Loew’s Incorporated (the plaintiffs), this ruling was reversed. The Supreme Court held that even though Schneer's may not have been aware of any copyright violations when leasing films from distributors, ignorance does not absolve them from liability for copyright infringement under U.S law.

The dissenting opinion in the case of United States v. Schneer's Atlanta, Inc., 1956 argued that the majority had incorrectly interpreted and applied the Sherman Antitrust Act. The dissenters believed that there was no violation of this act because there was no evidence to suggest a conspiracy or agreement between Schneer's Atlanta, Inc. and other companies to fix prices or restrict competition within their industry. They also disagreed with the majority’s view on monopolies, arguing that not all monopolies are inherently illegal under antitrust laws; only those which result from anti-competitive practices should be considered unlawful. Furthermore, they contended that Schneer's business practices were simply competitive strategies rather than attempts at market domination through unfair means.
