Appellant corporation, as assignee-licensee of Letters Patent No. 2,-078,264, sued appellees, alleging that the latter were manufacturing and selling the patented product without permission or right. Appellant asked an injunction and an accounting. The District Court, after hearing without a jury the evidence offered by plaintiff-appellant, dismissed the complaint.

After considering the evidence in the light most favorable to plaintiff-appellant, Higashi v. Shifflett, 1952, 90 U.S. App.D.C. 302, 195 F.2d 784, we have concluded that a prima facie case was not made out. The judgment must accordingly be

Affirmed.
