delivered the opinion of the Court:
Appeal from a -final decision of the Patent Office refusing a patent on certain claims. An interference was formerly declared between- this application and applications of William H. *343Lieber and Simonds & Smith. The interference involved five counts. On motion to dissolve as to appellant, Thomas W. Capen, the examiner held that count 4 was unpatentable, and that appellant was not entitled to make the other counts. All parties acquiesced in the decision as to count 4, and the decision as to the other counts was affirmed by the Examiners in Chief, whose decision was in turn affirmed by the First Assistant Commissioner. AYe reproduce counts 1 and 5 as representative of the group:
“1. A rock crusher, comprising a rotatable concave crushing member, a rotatable convex crushing member internal of the concave member, means eccentrically supporting said members with the crushing surfaces nowhere in contact with each other, and means for feeding material from end to end of the members by the rotation thereof.”
“5. A rock crusher comprising a frame, two parallel rotatable shafts, one internal of the other, eccentrically carried by said frame, and coacting crusher heads carried by said rotatable shafts.”
Thereafter appellant presented an amendment containing new and broader claims, which the Examiners refused to entertain on the ground that they should have been presented during the time fixed by rule 109, or at least not later than the time the motion for dissolution was presented. He therefore refused to redeelare the interference. On appeal to the Assistant Commissioner the decision was affirmed, the Assistant Commissioner saying: “The Examiner properly refused to redeclare the interference. It is not necessary to decide how long after the time fixed by rule 109 applicant could have presented other claims, wdth the request to have them made part of the issue of the interference. but certainly if such action was desired it should have been taken while the interference was pending, in order that the question of the admissibility of these claims could have been ruled on inter paries; and applicant cannot now be allowed these claims.”
AYe agree with the Patent Office tribunals that appellant had no right to make the claims involved in the interference pro*344ceeding. Inasmuch as the Examiner and the Assistant Commissioner have fully and satisfactorily considered this question, we will not restate the reasons for our conclusion, but merely refer to their decisions.
Rule 109 permits any party to an interference, at any time within thirty days after preliminary statements have been received and approved, to file an amendment to his application, containing any claims which in his opinion should be made the basis of an interference between himself and any of the other parties. It is made the duty of the Examiner of Interferences to transmit the claims thus proposed to the primary examiner for' his determination. If the claims are allowed, the interference will bé redeclared, or other interferences will be declared, to include the new claims. The object of this rule obviously is to require the parties to an interference to have determined in that proceeding all rights growing out of their respective applications. In other words/ the rule affords either party to an interference full opportunity to put in issue matter which he may think patentable or common to the interfering applications, but Which was not included in the interference as originally declared by the primary examiner. In this case appellant did not comply with the rules of the office, and file an amendment' containing these claims prior to the dissolution of the interference. We therefore agree with the Patent Office that he was thereafter estopped to urge them. ’ Decision a finned.
