Even 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
Affirmed.
Hemphill Co. v. Coe, 74 App.D.C. 123, 124, 121 F.2d 897, 898: “Under Section 4915, an appeal from a decision of the Patent Office (Board of Appeals) to the Court of Customs and Patent Appeals precludes later maintenance of a bill in equity upon the same application. The remedies are alternative and mutually exclusive * * *. The remedy elected is conclusive of the issues raised and of those which might have been raised. A party therefore by filing a second application cannot obtain a review of questions which were, or might have been, determined on a review relating to the first.”
