APPEAL FROM THE CIRCUIT COURT OF THE UNITED
STATES FOR THE DISTRICT OF CONNECTICUT
Letters patent No. 277,941, granted May 22, 1883, to Cassius M. Richmond for an artificial denture, are void by reason of an abandonment of the invention to the public by the inventor before the patent was applied for. Letters patent No. 277,943, granted to Cassius M. Richmond May 22, 1883, for a process for preparing roots of teeth for the reception of artificial dentures, are void for want of novelty and for want of invention in the invention claimed in it.
It is no invention, within the meaning of the law, to perform with increased speed a series of surgical operations, old in themselves, and in the order in which they were before performed.
