ZIRCON CORP. v. ITC , No. 22-1649 (Fed. Cir. 2024)
Annotate this Case
In 2020, Zircon Corp. filed a complaint with the United States International Trade Commission alleging that Stanley Black & Decker, Inc. and Black & Decker (U.S.), Inc. violated section 337 of the Tariff Act of 1930 by importing and selling electronic stud finders that infringed on Zircon's patents. The Commission instituted an investigation based on Zircon's complaint. A Commission Administrative Law Judge (ALJ) found no violation of section 337. On review, the Commission affirmed the ALJ's finding of no violation.
The Commission's decision was based on two independent reasons. First, it affirmed the ALJ's determination that Zircon had not satisfied the economic prong of the domestic industry requirement. Zircon had argued that it met this requirement based on its investment in plant and equipment, its employment of labor and capital, and its investment in the exploitation of the asserted patents. However, the Commission found that Zircon had not provided an adequate basis to evaluate the investments and the significance of those investments with respect to each asserted patent.
Second, the Commission found each of the claims of the patents that were before the Commission were either invalid or not infringed. The Commission found that all the asserted claims of one patent would have been obvious in view of four prior art references; that several claims of two other patents were invalid as anticipated by or obvious in light of Zircon’s original stud finder; and that several of the claims of these two patents were not infringed.
Zircon appealed the Commission's decision, but the United States Court of Appeals for the Federal Circuit affirmed the Commission's decision. The court agreed with the Commission's interpretation of section 337 and found that substantial evidence supported the Commission's finding that Zircon failed to meet its burden to prove the existence of a domestic industry relating to articles protected by each of its patents.
