Coca-Cola Co. v. Koke Co. of America

Background

The Coca-Cola Company sued a rival making and selling a drink that imitated Coca-Cola and used the name "Koke." The company had long used and registered the Coca-Cola mark. The District Court granted an injunction for Coca-Cola, the Circuit Court of Appeals reversed, and the Supreme Court took the case to decide whether Coca-Cola’s own advertising or past use of cocaine in the drink prevented protection.

Reasoning

The Court examined whether the trademark had become a recognized name for the plaintiff’s beverage and whether prior advertising or earlier use of cocaine made the mark fraudulent. The Court found that Coca-Cola’s name had acquired a secondary meaning: people associated the name with the familiar drink, not with a drug. The Court rejected the argument that removing cocaine and earlier advertising made enforcement unfair. It also found the defendant chose "Koke" to benefit from Coca-Cola’s advertising, so Coca-Cola was entitled to relief against that imitation. However, the Court refused to let Coca-Cola exclude use of the common word "dope," calling it too featureless to be protected personally by the company.

Real world impact

The decision lets well-known product names stop clear imitators that trade on a famous name, while narrowing what courts will prevent. Generic or common words cannot be claimed exclusively, and ordinary product ingredients or coloring may be made by others unless accompanied by outside deception. The Court modified the lower injunction and affirmed the decree as changed.
