Sperry Gyroscope Co. v. Arma Engineering Co.
Headline: Court reverses dismissal and allows a patent owner to sue a private company in federal court over gyroscopic compasses sold to the Navy, rather than forcing the claim only against the United States.
Holding: The Court decided that a federal trial court has power to hear a patent owner's suit against a private manufacturer for making devices sold to the United States, because the 1918 statute does not clearly remove that jurisdiction.
- Allows patent owners to sue private manufacturers in federal court even for items sold to the U.S. Navy.
- Requires trial courts to decide whether the 1918 law bars relief as a factual legal question.
- Reverses dismissals that wrongly treat statutory defenses as jurisdictional bars.
Summary
Background
A patent owner sued an engineering company in federal court, saying the company made and sold gyroscopic compasses that infringed the owner's patents. The complaint said the company sold those compasses to the United States Navy under contract from about 1918 to 1923, and asked for damages and an injunction to stop further sales. The district court dismissed the case for lack of jurisdiction, and the patent owner appealed to the Supreme Court for a decision on that jurisdiction question.
Reasoning
The main question was whether a 1918 federal law—which directs certain patent claims against the United States to the Court of Claims—took away the district court’s power to hear this kind of suit against a private manufacturer. The Court said the statute’s meaning was not clearly written to strip district courts of power. Instead, the question whether the manufacturer is protected by the statute is a matter for the trial court to decide on the merits. Because nothing in the law plainly removed the district court’s authority, the Supreme Court held there was jurisdiction and reversed the dismissal.
Real world impact
The ruling sends the case back to the district court to decide whether the 1918 law actually bars relief in this specific factual situation. Practically, it lets patent owners proceed in federal trial courts against private makers who sold patented items to the government unless the statute clearly prevents that suit.
