Opinion
No. 9084.
Argued June 20, 1946.
Decided July 1, 1946.
Appeal from the District Court of the United States for the Western District of Pennsylvania; Robert M. Gibson, Judge.
Action by Charles Drexler and the Charles Drexler Company, Inc., against Charles A. Koza and John A. Anderson for patent infringement, wherein the Invincible Tool Company was made a defendant by amended complaint. From a judgment in favor of plaintiff 62 F. Supp. 473, the defendants appeal.
Judgment affirmed.
John D. Meyer, of Pittsburgh, Pa. (Frank Keiper, of Rochester, N Y, on the brief), for appellants.
Ralph G. Lockwood, of Indianapolis, Ind. (Elmer L. Goldsmith and Harold R. Woodard, both of Indianapolis, Ind., and Fulton B. Flick, of Pittsburgh, Pa., on the brief), for appellees.
Before GOODRICH and O'CONNELL, Circuit Judges, and KALODNER, District Judge.
The points presented in this appeal are, in our opinion, purely questions of fact. The chief one of these is whether one or the other witness, upon whose testimony the outcome of the lawsuit depended, was telling the truth. The appellants say the trial judge should have answered the question contrary to the way he did answer it. The conclusion upon the question of credibility is peculiarly one for the trier of the fact. Upon this and the other issues of fact there is ample testimony to support the conclusion of the District Judge and we cannot say that his conclusion was clearly erroneous.
The judgment is affirmed.
