After a comprehensive trial in the district court, the complaint of the appellant-inventor, asking recovery against appellees of royalties under three license agreements, was dismissed. From the order of dismissal, this appeal is taken and has been heard and duly considered *710 upon the oral arguments and briefs of the attorneys and upon the record in the case.

Judge Weick, the trial judge, now a member of this court, wrote an opinion carefully discussing the pertinent issues in the case; and, in our view, correctly deciding them.

Accordingly, for the reasons stated in the opinion of the district court reported at 165 F.Supp. 776, the order dismissing the complaint is affirmed.
