Overview
Case summary
This equity suit involves patent licensing restrictions on asphalt block manufacturing machines. The International Pavement Company (plaintiff) granted an exclusive license to Trinidad Asphaltum Block Company in 1893, containing a clause restricting assignment of the patented machines without plaintiff's consent. When Trinidad Company's assets were sold to Benjamin F. Richardson (defendant) in 1894, defendant took possession of two Dietz patent machines. Plaintiff conditionally consented to the transfer but defendant failed to fulfill conditions. After defendant breached the license terms, plaintiff canceled it and sought an injunction to prevent defendant from using the machines. The court held that the restrictive clause was valid, defendant had notice of it, and equitable principles supported an injunction against defendant's continued use in violation of the license terms.
Abstract
Plaintiff granted an exclusive license for patented asphalt block manufacturing machines with a clause restricting assignment without consent. Upon asset sale to defendant, who took possession of the machines, plaintiff gave conditional consent that defendant breached, leading to license cancellation and a suit for injunction. The court upheld the restriction's validity, noted defendant's notice, and issued an injunction prohibiting use or disposal in violation of the license terms.
