Overview
Case summary
The St. Louis Car-Coupler Company sued Shickle, Harrison & Howard Iron Company for patent infringement related to car couplers covered by two patents (reissue No. 10,941 and original No. 519,216). The patents involved combination claims of four elements: drawheads, knuckle, pivot pin, and locking pin. Defendant manufactured and sold knuckles to railroad companies that had previously purchased complete couplers from plaintiff, for the sole purpose of replacing broken knuckles. The trial court found infringement, holding that replacing knuckles constituted reconstruction. On appeal, the Circuit Court of Appeals reversed, holding that replacement of a broken knuckle is repair, not reconstruction, when the drawheads remain serviceable. The court applied the established rule that a purchaser of a patented machine has the right to repair broken parts not separately patented, provided the machine retains its identity. The knuckle was found to be less durable than other parts, and its replacement was analogous to cases where replacement of worn parts was permitted. The appellate court remanded with directions to dismiss the complaint.
Abstract
Patent holder sued manufacturer for infringement after the latter sold replacement knuckles for patented car couplers to prior purchasers. Trial court held replacement constituted reconstruction and found infringement, but appellate court reversed, ruling it was permissible repair of a broken, less durable part while the machine retained its identity. Case remanded with directions to dismiss the complaint.

Notable quotes
“The rule is well established that one who purchases a machine or mechanical contrivance consisting of several distinct parts, which, as a whole, is covered by a patent, has the right, by virtue of his purchase from the patentee, to repair a part of the machine or device which happens to be broken through accident, or which becomes so far worn as to render the machine inoperative, provided the machine, as a whole, still retains its identity, and what is done in the way of rendering it operative does not amount to reconstruction, and provided, further, that the part so replaced is not separately covered by a patent.”majority — Explaining the legal principle of repair right for patented devices.Core legal rule applied in the case.
“It can hardly be supposed that a railroad company would equip its cars with a patent coupling apparatus like the one in controversy, one part whereof is liable to be broken long before the drawheads are worn out, unless the purchase of the coupling apparatus was made on the implied understanding that the purchaser should have the right to replace that part of the apparatus, if it was accidentally broken, without being compelled to pay further tribute to the owner of the patent.”majority — Reasoning why replacement of knuckle should be allowed as repair.Practical consideration supporting holding.
