Heyer v. Duplicator Manufacturing Co., 263 U.S. 100 (1923)
Heyer v. Duplicator Manufacturing Company
Argued October 15, 16, 1923
Decided November 12, 1923
263 U.S. 100
The sale, by the patentee, of a costly and durable copying machine dependent for its operation on bands of gelatine, which are attached to spools and which cost little and are quickly used up, implies a right in the purchaser to replace such bands as they wear out, without further consent of the seller, and their manufacture and sale for that purpose by another is therefore not an infringement, though the band, when used in the combination, is covered by the patent. Wilson v. Simpson, 9 How. 109. P. 263 U. S. 101.
284 F. 242 reversed.
