Six Wheel Corp. v. Sterling Motor Truck Co.
Opinion
Lead Opinion
McCormick, J.
By this suit in equity the plaintiff eorpo- ’ ration as assignee of Patent No. 1,655,481, granted to David H. Van Letíven on January 10, 1928, seeks an injunction and damaged against defendants for alleged infringement of said letters patent.
Defendants have asserted many defenses by their answers to this suit, but it is considered unnecessary to mention several of them because of the conclusions that have been reached upon the paramount issues of validity, scope, and infringement of the patent. Moreover, a most general statement of conclusions must suffice herein rather than an extended assignment of reasons that have impelled the court to reach its decision. This last situation is imperative because of the pressure of work in the court.
The patent in suit is for improvement in running gears, and especially to the six-wheel type of chassis of motor vehicles. The claims in issue are the tenth and twelfth claims of the patent. The main contention of complainant is that these claims should be given broad construction because of the advance in the art that was wrought by Van Leuven in the invention covered by the patent herein. I cannot agree with this contention.
