Overview
Case summary
This patent infringement case involves the Thomson-Houston Electric Company, assignee of the Van Depoele patent for improvements in traveling contacts for electric railways, suing the Kelsey Electric Railway Specialty Company for contributory infringement. The patent covers a combination including an overhead conductor, car with contact device, and trailing arm. Kelsey manufactured and sold trolley stands used in electric railway systems. The circuit court granted a preliminary injunction against Kelsey. On appeal, the Circuit Court of Appeals modified the injunction, holding that while contributory infringement could be found based on Kelsey's advertisements showing willingness to cooperate with infringers, the injunction was too sweeping. The court clarified that sales for replacement of broken or worn trolley stands are permitted, as is substitution of improved stands by purchasers, but reconstruction of the patented combination is not allowed. The dissent argued there was no evidence of infringement and Kelsey had right to sell unpatented articles.
Abstract
In this patent infringement suit, the assignee of a patent for improvements in traveling contacts for electric railways accused a manufacturer of contributory infringement for selling trolley stands used in infringing electric railway systems. The trial court issued a preliminary injunction, which the appellate court modified to permit sales for replacement of broken or worn stands and substitution of improved stands by purchasers, while prohibiting reconstruction of the patented combination. The dissent contended there was no evidence of infringement and that the seller had the right to sell unpatented articles.
