Thе appeal at bar was taken from a judgment of the court below declaring patent No. 2,406,951 to be void and granting certain other relief to Etten which need not be detailed here. The judgment of the court, however, did not dispose of the сounterclaim filed by the defendant and оf all the issues raised by the plaintiff’s assertion that the defendants wefe engaged in а conspiracy which damaged the plaintiff.
Rule 54(b) of the Federal Rules of Civil Procedure, 28 U.S.C.A., provides: “When more than one claim for relief is presented in an action, whether as a claim [or] counterclaim, * * * the court may direct the entry of a final judgment upon one or morе but less than all of the claims only upon an express determination that there is nо just reason for delay and upon an express direction for the entry of judgment. In thе absence of such determination аnd direction, any order or other form of decision, however designated, which adjudicates less-than all the claims shall not terminate the action as to any of the claims, and the order or other form of decision is subject to revision at any time before the entry of judgment adjudicating all the claim.”
In the instant case the сourt below did not enter a final judgment upon all the claims and did not make the detеrmination, required by Rule 54(b). It follows that under the сircumstances the judgment appeаled from is not a final judgment. We therefore must dismiss the appeal. Should, however, the court below see fit on remand to vаcate the judgment here appеaled from, to file a certificate as required by Rule 54(b) and to render a judgment in con *303 formity therewith and if the present aрpellants should appeal to this сourt from that judgment, if entered, this court would deem it unnecessary to have the parties reprint briefs or appendices. We may not and do not express any opinion as to whether or not there is any “just reason for delay” in the determination of all the claims. See Rule 54(b).
Accordingly the appeal will be dismissed for want of jurisdiction.
