Overview
Case summary
Thomson-Houston Electric Company sued Union Railway Company and New York, Elmsford & White Plains Railway Company for infringing the Van Depoele patent (No. 495,443) for traveling contacts for electric railways. The patent had been previously adjudicated valid in the same circuit, with the prior defendant acquiescing and taking licenses. The manufacturer of the trolleys used by defendants, Nuttall Company, also conceded validity and took licenses. The court granted a preliminary injunction, forbidding defendants from using infringing combinations except for 14 cars (10 on Union Railway, 4 on White Plains road) currently using Nuttall trolleys, as it was unclear whether these trolleys were covered by the license to Nuttall Company.
Abstract
Plaintiff sued defendants for infringing a patent on traveling contacts for electric railways, previously adjudicated valid with prior defendants and manufacturer taking licenses. Court granted preliminary injunction against use of infringing combinations, except for 14 cars currently in use where license coverage was unclear. This restrained ongoing infringement while allowing limited existing operations.
