Transparent-Wrap Machine Corp. v. Stokes & Smith Co.
Argued January 7, 8, 1947
Decided February 3, 1947
329 U.S. 637
A patent licensing agreement granted an exclusive license to manufacture and sell in the United States, Canada and Mexico a patented machine under the patents then owned or later acquired by the licensor, subject to a condition that the licensee assign to the licensor any improvement patents applicable to the machine and suitable for use in connection with it.
Held: the inclusion in the license of the condition requiring the licensee to assign improvement patents is not per se illegal and unenforceable. Pp. 329 U. S. 642-648.
