Williams Manufacturing Co. v. United Shoe Machinery Corp.
Argued February 13, 1942
Decided May 25, 1942
316 U.S. 364
1. In a patent infringement suit, concurrent findings of the two lower federal courts to the effect that combinations claimed, though involving old mechanical construction, combine these in the machine in a new way, so as to produce a new result, are findings of fact which will not be disturbed by this Court where there is evidence to support them. P. 316 U. S. 367.
2. A claim in a patent for a new combination of specified means, applicable to a portion of an old machine, which describes or refers to the older mechanism in order to show the application and operation of the improvement, is not to be construed as embracing the old as well as the new. P. 316 U. S. 368.
121 F.2d 273 affirmed.
Certiorari, 314 U.S. 600, to review the affirmance of a decree of the District Court, 29 F.Supp. 1015, sustaining certain claims of a patent, in a suit for infringement.
