This appeal is from dismissal of a complaint under R.S. § 4915, 35 U.S.C.A. § 63, to obtain a patent on an improved process for treating gaseous fluids with solid materials, and more particularly for converting hydrocarbon oils in the presence of solid catalysts. We think the District Court was not clearly wrong in finding, in substantial agreement with the Patent Office, that the appealed claims do not show invention over the prior art.

Affirmed.
