Appellant brought this suit to recover damages alleged to have been caused by unlawful conduct of appellees in causing the loss of appellant’s rights in two patent applications. Appellant has been compelled by a judgment of the United States District Court for the Eastern District of Virginia, affirmed by the Court of Appeals for the Fourth Circuit, to assign these patents to the United States. Kober v. United States, 170 F.2d 590, certiorari denied, 336 U.S. 945, 69 S.Ct. 812. We find no prejudicial error in the record. The orders of the District Court are therefore affirmed.
