Haupt v. United States
Argued November 10, 1920
Decided December 6, 1920
254 U.S. 272
Appellant sued to reoover a large sum of money for the use which he claimed the government had made of his patented improvement in dike and breakwaters in the construction of jetties, which, with dredging, had resulted in rendering navigable to seagoing vessel the changel of Aranas Pass on the coast of Texas. Held that the appropriation acts evinced the willingness of Congress to expend money in testing his patented devices, but no intention to pay him until their usefulness should be proved, and that no promise of the government to pay him for the use made could reasonably be implied. P. 254 U. S. 278.
53 Ct.Clms. 591 affirmed.
The case is stated in the opinion.
