¶2H. S. Miller, United States Patent Office, Washington, D. C., with whom E. L. Reynolds, Solicitor, United States Patent Office, Washington, D. C., was on the brief, for appellee.
¶3Before EDGERTON, PROCTOR, and BAZELON, Circuit Judges.
¶5This is a suit under 35 U.S.C.A. § 63, R.S. § 4915, for a patent on an electrically insulating layer structure such as a floor rug. We see no reason to disturb the finding of the Patent Office and the District Court that the claims fail to show invention over the patents cited by appellee.
