¶7Appeal from a decree dismissing the bill of complaint which was based upon letters patent No. 839,356, granted to complainant for a process of dividing diamonds.
¶8Edwin J. Prindle (Arthur Wright, on the brief), for appellant.
¶9Johnson & Galston (Clarence G. Galston, of counsel), for appellees.
¶10Before COXE, WARD, and NOYES, Circuit Judges.
¶13We agree fully with the opinion of Judge Hough that the method of sawing a diamond described and claimed does not involve invention. The fact that the object to be divided is of great value does not change what would otherwise be mechanical skill into invention. It might, as pointed out, require unusual courage for the operator .to risk such a process on so valuable an article, but courage is not patentable.
¶14We deem it unnecessary to add anything to the opinion of the Circuit Court.
¶15The decree is affirmed.
