P filed suit against D seeking an injunction for the infringement of Patent No. '674, issued on July 25, 1933, for a pneumatic 'puffing machine' whose application had been filed on January 21, 1931. D claimed in part that the patent was invalid because it too nearly was anticipated by the published art; that it was not infringed; and that there had been a prior use of it by one Haas as early as 1930. D also filed a counterclaim, based upon P's interference with his business by the wanton bringing of the suit in question. The patent was for a pneumatic machine for quilting and the art contained nothing of the kind before except Haas' machine, but the patent took into effect the venturi principle where swiftly moving air entering a larger tube creates a vacuum at the end of the smaller and sucks whatever substance forward to make a mixture. After hearing evidence on the basic physical principles involved and also on Haas’ prior machine, the court held the patent invalid. Both parties appealed.
