In the United States v. Esnault-Pelterie case of 1936, the Supreme Court ruled on a patent dispute involving airplane technology. Robert Esnault-Pelterie, a French inventor and aviation pioneer, held patents for an aerodynamic wing design that he claimed was infringed upon by several American aircraft manufacturers during World War I under licenses issued by the U.S government. The defendants argued that they were protected from infringement claims because their actions were authorized by federal law which allowed such use in times of war or emergency without permission from patent holders. The court sided with the defendants stating that Congress had indeed granted this authority to promote national defense efforts during wartime conditions and therefore no compensation was due to Mr. Pelterie for alleged infringements occurring under these circumstances.

The dissenting opinion in the United States v. Esnault-Pelterie case was not explicitly recorded or made available, which is common for many Supreme Court cases especially during that period of time. Therefore, a summary of the dissenting opinion cannot be provided as it does not exist in public record.
