Hetronic manufactured remote controls for construction equipment, and Abitron claimed rights under a distribution arrangement before selling competing products abroad. Hetronic sought damages under the Lanham Act for foreign sales, and the lower courts applied the statute to that conduct. The Court held that the relevant Lanham Act provisions are not extraterritorial and that the focus is on the location of the infringing use in commerce. The Court vacated and remanded for the lower court to apply that domestic-use rule.
