United States v. National Lead Co.

Background

The United States sued a large paint- and chemical-industry company (National Lead), its subsidiary (Titan Inc.), and a major chemical company (du Pont), charging them with running an international cartel in titanium pigments and related products dating from 1920. The District Court found they used patent exchanges and territorial agreements to dominate the world titanium-pigment market, cancelled many contracts, and entered a detailed decree to stop the conduct. The Supreme Court affirmed most of the District Court's judgment on June 23, 1947.

Reasoning

The Supreme Court reviewed the trial record and agreed that National Lead, Titan Inc., and du Pont violated the antitrust laws, including a finding that du Pont joined the combination after 1933. The Court affirmed the decree that cancels the cartel agreements and requires the defendants to grant nonexclusive licenses under defined patents at uniform, reasonable royalties, while preserving limited patent rights. The Court rejected the government's request for compulsory royalty-free licenses and declined to order physical plant divestitures.

Real world impact

The ruling clears the way for more competitors to use patent-covered methods under court-ordered licenses, making market entry easier than under the old cartel rules. The decree also bars enforcing foreign patents to block exports and requires plans to divest certain foreign stockholdings. Because royalties remain, some competitive barriers may persist and further challenges or adjustments are possible as the decree is implemented.

Dissents or concurrances

Three Justices dissented in part, arguing the court should have required royalty-free licensing and stronger measures, saying royalties would let the dominant firms retain undue advantages.
