William Cramp & Sons Ship & Engine Building Co. v. International Curtis Marine Turbine Co.
Headline: Patent ruling limits the Government’s 1910 law, blocks an automatic patent license, and holds contractors can be liable for using patented devices, requiring accounting and possible compensation for patent owners in shipbuilding.
Holding: The Court held that the 1910 law did not automatically give the United States or its contractors a general license to use patents, so contractors may be liable and accounting must proceed under the proper statutory construction.
- Prevents contractors from assuming they can use patented inventions without consent when building for the U.S.
- Allows patent owners to seek compensation and accounting for government-related uses.
- Clarifies that contracting with the United States does not turn contractors into government officials.
Summary
Background
A private shipbuilder contracted with the Navy to build torpedo boat destroyers in 1908 and again in 1911. The owners of turbine patents sued the builder after turbine engines were placed in the 1908 ships and later sought damages tied to the 1911 ships as well. The builder argued a 1910 federal law gave the United States a license to use patents, so work done for the Navy should not count as infringement by the builder.
Reasoning
The Court considered whether the 1910 law automatically gave the United States a universal license to use all patents and whether a private contractor could rely on that supposed license. The opinion rejects the broad interpretation. The law, the Court said, was meant to secure compensation where the United States had used patented inventions without a license, not to authorize contractors to take patent rights freely. Contractors do not become government officials by contracting and cannot assume a blanket right to use others’ patents.
Real world impact
As a result, the accounting and damage inquiry tied to the 1911 contracts may go forward under the correct reading of the 1910 law. Patent owners can press claims for compensation when the Government or its agents use inventions without consent. The case was sent back to the lower court for further proceedings consistent with this ruling, so the final money outcome is not decided here.
