Life Technologies Corporation, Petitioners v. Promega Corporation.

Summary

The Court held that supplying a single component of a multicomponent patented invention does not satisfy the statutory phrase “all or a substantial portion” of the components under 35 U.S.C. §271(f)(1). Accordingly, the Federal Circuit’s judgment of infringement was reversed and the case remanded. The decision rests on a textual, quantitative interpretation of the term “substantial portion.”
