Summary

Background

In 1927 an inventor employed a machinist to build and improve a machine and asked the machinist to keep the invention secret and not use it for himself. The inventor sued in a New York state court and won a judgment that the machinist had to assign a later-issued patent, stop using or selling the invention, and pay costs. After that judgment the machinist sued in federal court claiming his patent and asking the federal court to bar the state case.

Reasoning

The Court recognized that federal courts have exclusive power over suits that truly arise under the patent laws. But it found the state suit was not a patent lawsuit: it was a claim for breach of a confidentiality agreement and a wrongful use of an undisclosed invention. The state claim existed independently of patent law and sought assignment of the patent based on the earlier trust and breach, not a federal decree invalidating the patent. The Court explained that proving those facts in state court does not amount to a universal invalidation of the patent and that a state court may enforce the inventor’s prior rights.

Real world impact

The decision lets state courts hear and enforce claims by inventors or employers when a worker secretly patents an invention taken in breach of confidence. It means employers have a state-law route to recover rights and patents obtained by trusted workers who violated secrecy agreements, while clearer patent-validity rulings remain for federal patent cases.
