Adamson v. Gilliland
Submitted November 13, 1916
Decided January 8, 1917
242 U.S. 350
Upon considering the evidence, the Court finds grave reasons for agreeing with the district judge that the respondent copied the petitioner's patented invention.
The rule which gives conclusive effect to a finding made by a judge who saw the witnesses when there is testimony consistent with it and the finding depends on conflicting testimony or the credibility of witnesses is peculiarly applicable in a case wherein a patent is assailed by oral evidence of an alleged unpatented anticipation.
227 F. 93 reversed.
