Armstrong Paint & Varnish Works v. Nu-Enamel Corp.
Headline: Trademark dispute over 'Nu-Enamel' upheld as protectable after acquiring distinct meaning, letting the company block a rival’s similar 'Nu-Beauty Enamel' and pursue damages in federal court.
Holding: The Court affirmed the appeals court, holding that although 'Nu-Enamel' is descriptive it acquired a secondary meaning that gives the company common-law ownership and supports federal claims of trademark infringement and unfair competition, so the case returns for remedies.
- Allows companies with established secondary meaning to sue for infringement in federal court.
- Registration under the 1920 act does not automatically prove ownership; owners must prove their rights.
- Stops competitors from using confusingly similar names that lead merchants to pass off products.
Summary
Background
Nu-Enamel Corporation of Illinois sued a fellow Illinois paint maker, Armstrong Paint and Varnish Works, after Armstrong sold enamel under the name "Nu-Beauty Enamel." The Illinois company had registered "Nu-Enamel" under the 1920 Trade-Mark Act and later sold its assets to a Delaware corporation that intervened in the suit. The District Court held that "Nu-Enamel" was merely descriptive or generic and dismissed the claim; the Court of Appeals reversed, finding the name had acquired a meaning identifying the plaintiff’s goods only.
Reasoning
The Supreme Court agreed with the Court of Appeals. The Justices said the 1920 Act does not by itself create ownership rights in a registration, and registrations can be attacked. But the statute allows federal suits to protect registered marks and provides remedies, including possible treble damages, when ownership is shown. The Court found that although "Nu-Enamel" is descriptive of enamels, it had acquired a "secondary meaning" identifying the plaintiff’s products, giving the company common-law rights. Because the mark functioned as the company’s identifier and Armstrong’s mark was confusingly similar as used on enamels, infringement and unfair competition were established.
Real world impact
The case sends the dispute back to the District Court to decide damages and the proper relief. It confirms that descriptive names can get protection if they come to identify one maker’s goods, that federal courts may hear such claims when registration is involved, and that registration alone does not automatically prove ownership.
