Syllabus

<p>Upon considering the evidence the court finds grave reasons for agreeing with the District Judge that the respondent copied the petitioner’s patented invention.</p> <p>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.</p> <p>One who opposes a patent by oral evidence of a prior discovery, must prove his case beyond a reasonable doubt. The Barbed Wire Patent, 143 U. S. 275, 284.</p>
