This is a patent case, brought in the District Court under 35 U.S.C. § 145, 66 Stat. 803 (1952), to authorize the Commissioner of Patents to issue a patent. The Patent Office considered that plaintiff-appellant’s application, covering a clamp for outboard motors, Serial No. 226,709, did not show patentability over the prior art. The District Court agreed, and dismissed the complaint. We find no reversible error.

Affirmed.
