Zenith Radio Corp. v. Hazeltine Research, Inc.

Background

A U.S. electronics maker, Zenith, stopped renewing a long-standing license with a domestic patent company, HRI. HRI sued Zenith for patent infringement. Zenith counterclaimed, saying HRI and its parent, Hazeltine, conspired with foreign patent pools in Canada, England, and Australia to keep Zenith out of those markets and that HRI misused its patents to extract unfair royalties.

Reasoning

The District Court found HRI had misused its patents and had conspired with foreign pools, awarding treble damages and broad injunctions. The Court of Appeals agreed on some misuse findings but set aside damages and injunctions in part, and vacated the judgments against Hazeltine for lack of jurisdiction. The Supreme Court reviewed the facts and law. It held the judgments against Hazeltine were improper because Hazeltine had not been made a party. It reversed the Court of Appeals on Canada, finding enough evidence that the Canadian pool and HRI injured Zenith during the damage period, so damages and an injunction as to Canada are reinstated. It agreed the English and Australian awards were unsupported. The Court also ruled that forcing licensees to pay royalties on products that do not use the patented invention is patent misuse, although it left some antitrust questions for the lower courts to decide.

Real world impact

Manufacturers selling abroad gain stronger protection against coordinated foreign patent pools that block imports. Patent owners are limited from using a patent to force royalties on unrelated, unpatented products. The decision also underscores that courts may not enter personal judgments against corporate parents that were never made parties to the suit.

Dissents or concurrances

Justice Harlan agreed with much of the result but disagreed on the new rule about percentage-of-sales royalties, warning it creates uncertainty and questioning overturning aspects of prior precedent.
