Summary
Background
A steel company (successor to the Bethlehem Iron Company) claimed the United States used a patented improvement to a gun breech invented by an employee, Owen F. Leibert. The Ordnance Bureau reviewed the Leibert application, tested related drawings at the Watervliet Arsenal, and later used a Department design prepared by a draftsman, known as the Model 1895. The Steel Company said the Model 1895 incorporated Leibert’s patented mechanism, sued the United States, and the Court of Claims found the Leibert patent valid and that the Government used it, awarding $67,000.
Reasoning
The central question was whether the Ordnance Bureau’s behavior showed recognition and consent to use the patent or whether the Government had wrongfully taken it. The Court explained that where the Government uses a patented invention with the owner’s consent or without repudiating the owner’s title, an implied contract to pay reasonable compensation arises. The Bureau’s correspondence and offer to assist the Company in litigation showed acceptance of a judicial decision rather than hostile appropriation, so the implied-payment rule applied and the award stood.
Real world impact
The ruling requires the United States to treat certain uses of private patented military improvements as creating an obligation to pay, rather than as governmental theft. It supports compensation for inventors and companies whose patented military designs are adopted by the Government and affirms the lower court’s $67,000 judgment.
