Notable quotes
“Defendants, however, must determine, at their peril, whether the purchaser buys to use for infringement, or only for legitimate repair; but this permission to repair does not give authority to reconstruct or rebuild a combination which has been sold by the owner of the patent.”LACOMBE, Circuit Judge — Defining scope of injunction regarding repair vs. reconstructionClarifies limits of permissible repair under patent law
“Injunction may run against the officers as well as the corporation defendant. Possibly, under the stimulus of an apprehended prosecution for contempt, they may familiarize themselves with the kind of goods their company is publicly advertising for sale, and thus infringement may be more satisfactorily checked than it would otherwise be.”LACOMBE, Circuit Judge — Extending injunction to corporate officersHighlights enforcement strategy to deter infringement
