Summary
Background
A company that owned a scaffold patent sued Chain Belt Company and Egbert Whitney, seeking money, an accounting, and both preliminary and final injunctions to stop sales of certain hoist machines. A lower trial court found infringement and issued an injunction; an appellate court agreed the patent showed some invention but limited the injunction’s reach against one called the "Little Wonder" machine. The dispute involved earlier devices, including a patent by William Murray, which the defendants said anticipated the claimed invention.
Reasoning
The central question was whether the Henderson patent showed true invention beyond what was already known. The Court closely examined the prior devices and Henderson’s own testimony about how he developed his design. The Justices concluded Henderson had little experience, borrowed existing U-frame ideas, and made only simple mechanical changes that anyone could make to avoid a previous design. Because the change was obvious and prompted by evasion rather than creative discovery, the Court found no real invention and held the patent invalid.
Real world impact
By declaring the Henderson patent invalid, the Court removed the legal basis for the injunctions and ordered the infringement case dismissed. That means the defendants are no longer legally barred from making or selling the disputed scaffolding and hoist machines. The decision resolves this suit against the patent owner and undermines future enforcement efforts that rest on the same Henderson patent.
