Overview
Case summary
Thomson-Houston Electric Company sued Union Railway Company for infringing its patent (Van Depoele patent No. 495,443) for an electric trolley switching device. An earlier preliminary injunction had excepted 10 trolleys due to an inference they were licensed, but new proofs showed they were not. The defendant acquired these trolleys from Walker Company after a prior infringement decision, choosing them over General Electric Company equipment due to lower price. The court held that public inconvenience from stopping the cars was insufficient to deny an injunction, but modified it to allow 30 days for substituting noninfringing equipment, as Walker Company could compensate the defendant for any losses.
Abstract
Plaintiff sued defendant for infringing a patent on an electric trolley switching device. An earlier preliminary injunction excepted 10 trolleys based on a mistaken inference of licensing, but new evidence showed they were acquired from a third party after a prior infringement ruling and were infringing. The court granted an injunction against their further use but suspended it for 30 days to allow substitution with noninfringing equipment, rejecting public inconvenience as a bar.
