1Opinion of the Court
SIMONS, Circuit Judge.
The patent, the validity of which alone is in issue in the present infringement suit, is one to Lyle A. Weed, No. 2,014,676, granted September 17, 1935, upon an application filed November 19, 1934. It relates to germicides suitable for internal and external medication, and to methods of destroying, in the presence of living tissue, micro-organisms which are pathogenic to man or higher animals. Infringement of the claims in suit is conceded if the claims be valid.' A decree of invalidity, for want of patentable invention over the prior art, is challenged by the appeal.
