This is an action brought under R.S. § 4915.
The question is not new, and we had assumed that what we had already said on the subject would be considered as settling the point. For instance, in Jensen v. Lorenz, 68 App.D.C. 39, 92 F.2d 992, cer-tiorari denied 302 U.S. 751, 58 S.Ct. 271, 82 L.Ed. 581, we said of R.S. § 4911 that,
But appellant says that the phrase “all further proceedings” in R.S. § 4911 refers only to further proceedings in interference and not to subsequent ex parte prosecutions of the application of either party to the interference. From this stated premise, he deduces the conclusion that his failure at the time of the appeal by his adversary to elect to have “all further proceedings” conducted in accordance with R.S. § 4915 does not, after the conclusion of the appeal proceedings, bar him from pursuing his equitable remedy under the latter section. He says also that the Court of Customs and Patent Appeals is merely a part of the administrative machinery of the Patent Office and that its decisions bind only the Office and may be reviewed in an equity court at the instance of the losing party in a proceeding subsequently begun under R.S. § 4915. And, finally, he says
We have given careful consideration to these theories, and we are of the opinion they cannot be sustained. Both the history of the court review sections of the patent statute and the language of the several sections clearly indicate the purpose of Congress to require a defeated applicant to elect between an appeal to the Court of Customs and Patent Appeals and a suit under R.S. § 4915, but in no case to have both. And in an interference case the limitation applies equally to his successful opponent. The latter’s right to have the proceedings in equity is preserved by the provision in R.S. § 4911 authorizing him to have the appeal dismissed and to require his adversary to resort to R.S. § 4915. Nothing could be fairer than this. In short, the right to appeal to the Court of Customs and Patent Appeals is an optional right, and election to proceed there must be mutual, and where this happens, it confines all further proceedings to that court. If it were otherwise, the obvious purpose of the amendment of 1927,
The ingenious argument of counsel in this respect is well done, but we are unable to find any legal or logical basis on which to sustain it. We think, as we have said in our former opinions, that the decision of the Court of Customs and Patent Appeals, after submission of the case to it without protest, is conclusive as to all the matters adjudicated by it. The anomalous procedure of a new appeal through an equity proceeding never was intended and, as we have already suggested, would defeat the purpose of the 1927 amendments to R.S. § 4915, which was to limit resort to that section to cases in which the option to go to the Court of Customs and Patent Appeals had not been availed of.
