The U.S. Supreme Court case Chamberlain Machine Works v. United States in 1925 revolved around a dispute over patent rights and royalties between the Chamberlain Machine Works company and the U.S government. The company had patented an artillery fuse, which was used by the government during World War I without obtaining a license or paying any royalties to the company. Afterward, Chamberlain sued for compensation under a federal statute that allowed inventors to recover reasonable compensation from unauthorized use of their patents by the government. The court ruled against Chamberlain on two main grounds: first, it held that because Congress had not specifically provided for such claims in its appropriations for war expenses, there were no funds out of which payment could be made; secondly, it found that even if such funds existed, they would not be available to satisfy this claim since Congress did not intend them to be used in this way when it passed legislation authorizing wartime procurement. This decision established important precedents regarding governmental immunity from patent infringement suits and clarified how courts should interpret Congressional intent when considering whether specific appropriations can be used to pay judgments against the United States.

In the dissenting opinion for Chamberlain Machine Works v. United States, it was argued that the majority's decision to uphold a tax on machines used in manufacturing munitions during World War I was incorrect. The dissenting justices believed that this tax constituted an unlawful taking of property without just compensation, violating the Fifth Amendment rights of manufacturers like Chamberlain Machine Works. They contended that while Congress has broad powers to levy taxes under Article I Section 8 of the Constitution, these powers do not extend to imposing punitive financial burdens on specific industries or activities without providing fair compensation in return. Furthermore, they disagreed with the majority's interpretation of "war profits," arguing instead that any profit derived from wartime production should be considered legitimate and not subject to special taxation measures.
