¶1Mr. Louis D. Forward, member of the Bar of the Court of Appeals of the State of New York, of New York City, pro hac vice, by special leave of Court, with whom Messrs. Clarence M. Fisher, of Washington, D. C., and Raymond F. Adams, of New York City, were on the brief, for appellant.
¶2Mr. E. L. Reynolds, of Washington, D. C., with whom Mr. W. W. Cochran, Solicitor, United States Patent Office, of Washington, D. C., was on the brief, for appellee.
¶3Before MILLER, EDGERTON and ARNOLD, Associate Justices.
¶5Even assuming, although not deciding, that this proceeding was properly brought under Section 4915, R.S.,1 we are satisfied, nevertheless, that the disputed claims were unpatentable over the prior art; hence that they were properly rejected by the Patent Office and by the District Court.2
¶6Affirmed.
