Foley v. United States

Background

An inventor offered the Navy a new method for drying smokeless powder and gave the Navy an option to use it in exchange for one cent per pound if the Navy built and tested his apparatus and a patent issued. The Navy built the experimental machine at Indian Head, Maryland, and tested it from October 1903 to October 1904. A patent issued to the inventor in June 1904. After testing, the Navy told the inventor the apparatus failed to justify further work. Years later the inventor’s estate sued the United States for unpaid royalties covering many pounds of powder the Government had produced.

Reasoning

The core question was whether the letters between the inventor and the Navy created a lasting contract or only a conditional option that the Navy could end. The Court agreed with the lower court that the Navy’s acceptance was expressly conditional on satisfactory tests. The Navy conducted the trial, judged the apparatus unsatisfactory, and notified the inventor, and his long silence amounted to acceptance of that decision. The Court also noted the lower court’s finding that the Government had not adopted the inventor’s special method; alternatively, if the Government’s methods necessarily produced the same result, the patents would not be an advance and might be invalid.

Real world impact

Because the Court treated the exchange as a conditional option ended by the Navy’s rejection, the inventor’s estate could not collect the claimed royalties. The decision shows that experimental testing and a formal rejection by a government bureau can terminate a hope for future payments absent a clear, continuing contract.
