Overview
Case summary
The American Soda-Fountain Company sued Green and others for infringing U.S. Patent No. 414,272, assigned from Theodore I. Witting, for improvements in soda water dispensing apparatus. The patent describes a case with ice chamber, cold-air chamber, removable syrup can with faucet, recess for glasses, and drop door with handle to operate faucet. Defendants did not deny infringement if the patent was valid, but challenged it on two grounds: (1) the combination lacked invention in view of prior art, and (2) the claim was for an unpatentable aggregation. The court rejected both defenses, finding no single prior patent contained all elements of the combination, and that the parts worked together to achieve a common purpose, making it a true patentable combination. The court ordered a decree in favor of the plaintiff.
Abstract
Plaintiff sued defendants for infringing a patent on improvements in soda water dispensing apparatus, which featured an ice chamber, cold-air chamber, removable syrup can with faucet, glass recess, and drop door mechanism. Defendants conceded infringement if valid but argued lack of invention due to prior art and unpatentable aggregation. Court rejected both defenses, finding no single prior patent anticipated the combination and that the elements cooperated for a common purpose, entering decree for plaintiff.
