On February 22, 2017, the U.S. Supreme Court ruled in Life Technologies Corp. v. Promega Corp. that supplying one component of a patented multicomponent invention produced outside the United States does not infringe that patent. The Court noted that a supplier may be liable for copyright infringement for supplying “all or a substantial portion of the components of the invention,” and held that the term “substantial” was to be viewed as a quantitative assessment and must be more than one part. The case relates to a DNA genetic testing toolkit patented by Promega, who sued the exclusive licensee Life Tech after they began selling the toolkits for unlicensed purposes. Life Tech produced one component out of five required parts in the United States before shipping it to its facility in the United Kingdom for production with the other four parts. Promega sued for patent infringement, claiming that the component produced in the United States was a substantial portion of the toolkit and arguing that the term “substantial portion” should be reviewed with both quantitative and qualitative measurements. The Court disagreed and held that “the statutory context points to a quantitative meaning.”
