delivered tlie opinion of the court:
This is an appeal in a trade-mark opposition proceeding from the decision of the Commissioner of Patents (58 USPQ 495) reversing the decision of the Examiner of Interferences sustaining appellant’s notice of opposition to the registration of appellee’s trade-mark and holding -that appellee was not entitled to register the mark under section 5 of the Trade-mark Act of February 20,1905.
Appellee’s mark comprises the notation “20th Century” displayed on a black background.
It is alleged in appellee’s application for registration that it has used its mark on its goods, including “ready-mixed paints,” since February 1, 1937.
In its notice of opposition appellant alleged that it was the owner of the trade-mark “20th Century” for use on a variety of articles, including “ready-mixed paints”; that it had used its mark on its goods *1098since long prior to Fébruary 1, 1937; and that it would be damaged by the registration of the mark to appellee.
Evidence was introduced by each of the parties.
In his decision the Examiner of Interferences stated that the marks of the parties were substantially identical; that some of the goods (ready-mixed paints) on which the respective marks were used were identical; that it appeared from the testimony introduced by appellant that ready-mixed paints were manufactured and sold by George D. Wetherill & Compaq, Inc. (hereinafter referred to as the Wetherill corporation) pursuant to an agreement entered into between that corporation and the appellant company at the time the appellant company was organized in 1911; and that it was the contention of counsel for appellant that, although “the entire business in the manufacture and sale of this brand of merchandise and the maintenance of records relating thereto has been carried out by the George D. Wetherill & Co. Inc., * * * such company has done so only in the capacity of an agent of the opposer, in accordance with the terms of the aforesaid agreement.” The examiner further stated that counsel for ap-pellee contended that the appellant company was a “mere ‘dummy’ corporation”; that the manufacture of “ready-mixed paints” and their sale under the trade-mark “20th Century” had been conducted by the Wetherill corporation on its own behalf; and that the Wetherill corporation “rather than the opposer [appellant] is therefore the owner of the mark.”
After stating the position of counsel for the parties, the examiner held that the question of title, as between appellant and the Wetherill corporation, was not of material consequence; that, regardless of the ownership of the mark, appellee was pot the first user of the mark; and that it was not'necessary to consider the question of title. In support of his position, the examiner cited the cases of Dubonnet Wine Corporation v. Ben-Burk, Inc., 28 C. C. P. A. (Patents) 1298, 121 F. (2d) 508, 50 USPQ 76, and Oxo, Limited v. Griffith Laboratories, Inc., 53 USPQ 264.
The examiner sustained the notice of opposition and held that ap-pellee was not entitled to the registration of its trade-mark.
On appeal, the Commissioner of Patents stated in his decision that it appeared from the record that the Wetherill corporation applied the mark “20th Century” to “its own goods in its own business and on its own behalf and not on behalf of opposer [appellant],” and that the question to be determined was whether “the mere appearance of the name ‘Revere Paint Company’ in association with the notation ‘20th Century’ on the labels and color cards of George D. Wether-ill & Company gives opposer such an interest in the mark ‘20th Century’ as qualifies it to oppose registration of that mark by applicant *1099[appellee].” The commissioner was of opinion that it did not. He further stated that “It was George D. Wetherill & Company and not opposer that associated the name ‘Revere Paint Company’ with the mark ‘20th Century,’ and it does not appear that George D. Wether-ill & Company did so for any benefit to opposer or even at opposer’s request. Even opposer’s consent to the display is only inferentially indicated in the record and not shown positively.”
The commissioner concluded from the evidence of record that appellant (opposer) had not established either ownership or the right to use the trade-mark “20th Century”; that it had not established any likelihood that it would be damaged by the registration of the mark to appellee; and that, therefore, it had not established its right to oppose the granting of registration to appellee.
The commissioner refused to give consideration to the evidence relating to the activities of the Wetherill corporation “for possible grounds for ex parte refusal of registration,” and, in this connection, stated that neither ownership nor use of the mark in question was pleaded by 'the Wetherill corporation, and that as the notice of opposition and the evidence on behalf of appellant were each directed solely to the use and ownership of the mark by appellant, appellee “was not called upon to meet the issue of whether George D. Wetherill & Company had any rights in the mark or to direct its cross-examination of opposer’s witness accordingly or to take proofs with regard thereto, and obviously * * * did not do so. * * * Accordingly the
proofs will not be considered for a possible ground for ex parte refusal of the registration for which applicant has applied.” The commissioner concluded his decision with the following statement:
In view of the above the decision of the Examiner of Trade-Mark Interferences is reversed and the notice of opposition is dismissed.
Thereafter, opposer (appellant) filed a request for reconsideration of the commissioner’s decision, claiming that the commissioner erred in dismissing appellant’s notice of opposition and in holding, ex parte, that appellee was entitled to register its mark.
The commissioner denied appellant’s petition for reconsideration and, in so doing, stated that the points raised therein had been fully considered in his decision.
Appellant’s witness Samuel R. Matlack, testified that he was president of both the appellant company and the Wetherill corporation; that at the time of the organization of the appellant company (March •13,1911) the directors of that company adopted a resolution which, he stated, authorized the president of the company “to enter into such arrangements with the George D. Wetherill & Company, Incorporated, as to the manufacture of paints and the sale of same as in his judgment he deems best”; and that “arrangements were entered into” with the *1100Wetherill corporation which were still in effect at the time of the taking of his testimony. What those arrangements were the witness did not state, nor does it appear from any other evidence of record what they were.
All of the other of appellant’s witnesses, with the exception of George Frederick Kurtz, were employed by the Wetherill corporation.
The witness Kurtz testified, among other things, that he was engaged in the hardware business under the name of Kurtz & Company in Philadelphia, Pennsylvania; that he purchased paints under the trademark “20th Century” from the Wetherill corporation; that he' sold “Wetherill’s ‘20th Century’ paint”; that he never had any business transactions with the appellant company; and that he never met anybody who represented the appellant company.
It appears from the testimony introduced by appellant that the appellant company does not manufacture or sell paints or any other articles; that it does not keep any books or accounts relative to the sale of any articles; that it transacts no business in the ordinary sense in which bookkeeping records might be required; that the paints referred to in the notice of opposition are manufactured and sold exclusively by the Wetherill corporation; that the Wetherill corporation receives payment for all such paints; that bills are rendered by that corporation.to its customers; and that the customers look to the Wetherill corporation for credits or redress on all paint sold by it under the trade-mark “20th. Century.” In short, there is nothing of record tending to establish that appellant (Revere Paint Company) has any interest whatsoever in the trade-mark “20th Century,” or in any goods sold by the Wetherill corporation under that trade-mark.
It is true that the Wetherill corporation provides labels for which it pays and on which appears the name of the appellant company, and that the name of the Wetherill corporation does not appear thereon. The evidence does not establish why the Wetherill corporation places appellant’s name on those labels, and we do not care to speculate as to why it is done.
There is nothing of record tending to establish that the appellant company ever received any money or anything else of value from the Wetherill corporation for the paints manufactured and sold by it. We are of opinion, therefore, that the. commissioner was clearly justified in holding as he did that there is nothing of record tending to establish that the Wetherill corporation was the agent of the appellant company, or that the appellant company had any right, title, or interest in the trade-mark “20th Century,” or that it would probably be damaged by the registration of the mark to appellee.
With regard to the case of Dubonnet Wine Corporation v. Ben-Burk Dio., supra, relied upon by the Examiner of Interference in support of *1101his holding that the question of title was not material to the issues in the instant case, we think it is sufficient to say that the decision in the Dubonnet case does not support the examiner’s views. In that case, the Dubonnet Wine Corporation (opposer) was the owner of two registrations under the Trade-mark Act of February W, 1906, of the trade-mark “Dubonnet” for use on wine, and, although it appeared that it was not engaged in any commercial business in connection with the manufacture or sale of wines and its mark was used by another, we, nevertheless, held that as it was the owner of the registrations referred to it was entitled to oppose the registration of the trade-mark “Dubonnet” to the applicant.
Prior to our decision in that case, we had repeatedly held that the validity of a registered trade-mark could not properly be challenged in an opposition proceeding; that evidence relating to the validity of an opposer’s registration was wholly irrelevant to the issues in such a proceeding; and that if a party deemed himself injured by a trade-mark registration, he should proceed in accordance with the provisions of section 13 of the Trade-mark Act of February 20, 1905, which authorize him to file a petition for the cancellation of such trade-mark registration. See Englander, etc. v. Continental Distilling Co., 25 C. C. P. A. (Patents) 1022, 95 F. (2d) 320, 37 USPQ 264, and cases cited therein.
Appellant is not the owner of a registration for the trade-mark “20th Century.” Accordingly, the decision in the Dubonnet case, sufra, has no application to the issues in the case at bar.
It is so well settled as to require no citation of authorities that as appellant failed to establish that it would probably be damaged by the registration of the trade-mark “20th Century” to appellee, its notice of opposition should have been, as it was, dismissed by the Commissioner of Patents.
In appellant’s reasons of appeal in this court it is stated that “The Commissioner erred in refusing to consider the proofs submitted by Opposer as ‘possible ground for ex parte refusal of the registration for which Applicant has applied.’ ”
We have repeatedly held that in opposition proceedings the tribunals of the Patent Office have the authority to determine ex farte whether or not the mark of an applicant is entitled to registration, regardless of the issues raised by the notice of opposition. Indeed, it is their duty to do so. See Englander, etc. v. Continental Distilling Co., sufra, and Dubonnet Wine Corf oration v. Ben-Burk, Inc., sufra.
In an ex farte consideration of the right of an applicant to register its mark, the Commissioner of Patents, not the opposer, represents the public — Frankfort Distilleries, Inc. v. Dextora Company, 26 C. C. P. A. (Patents) 1244,1249,103 F. (2d) 924, 41 USPQ 664 — and his decision *1102is final so far as the opposer is concerned. We hold, therefore, that appellant is not entitled to challenge here the action of the Commissioner of Patents refusing to consider the evidence relative to the activities of the Wetherill corporation “for possible grounds for ex parte refusal of registration.” Accordingly, the commissioner’s decision in that respect is not before us for consideration. See Islamd Road Bottling Go. v. Drink-Mor Beverage Co., 30 C. C. P. A. (Patents) 708, 132 F. (2d) 129, 56 USPQ 65. See also Island Road Bottling Co. v. Drink-Mor Beverage Co., 31 C. C. P. A. (Patents) 816, 140 F. (2d) 331, 60 USPQ 369, 372.
Had the commissioner rejected appellee’s application for registra-, tion and had appellee appealed to this court, the ex parte'issue of the right of appellee to register the mark would have been properly before us.
It has been suggested that it is the duty of this court, in order to safeguard the public interest, to decide on its own motion that appellee lias no right to the registration which it seeks. That the court has no such authority is so obvious as to require no discussion. Furthermore, the refusal of this court to extend its jurisdiction to matters not conferred upon it by the Congress and which are not inherent in the exercise of its judicial authority cannot with' reason be construed as sanctioning the registration of a trade-mark which the statute (section 5 of the Trade-Mark Act of February 20, 1905) prohibits. If the commissioner erred in granting appellee’s application for registration of the trade-mark “20th Century,” and if the Wetherill corporation is the owner of that mark or deems itself injured by the registration thereof, that company has a remedy, it may, under section IS of the Trade-Mark Act of February 20, 1905, petition the Commissioner of Patents to cancel appellee’s registration.
' For the reasons stated, the decision of the Commissioner of Patents, dismissing appellant’s notice of opposition, is affirmed.
