delivered the opinion of the Court:
This is an appeal from a decision of tbe Acting Commissioner *309of Patents, wherein he refused to allow certain claims of the applicant, Walter Scott, on the ground that they contained new matter not disclosed by the original specifications and drawings.
On April 19, 1895, nearly ten years ago, the applicant filed his application for a patent for certain improvements claimed to have been made by him in printing-machines of the rotary character, for the printing of newspapers. The application, as filed, contained eleven claims, some of which were subsequently abandoned, and others substituted in their place; and several other claims were added from time to time until the number reached twenty-three. At least two interferences were declared between the applicant and one Samuel G. Goss, who had an application pending at the same time. These successive interferences were dissolved on the motion of Goss, on the ground that there was no interference in fact. Subsequently a patent was issued to Goss.
Thereupon the appellant copied some of Goss’s claims, evidently for the purpose of another interference; and these are the matter-in controversy here; and they are the following:
“9. In a printing-press, the combination with a plurality of sets of printing mechanism arranged one above another, of means for starting and stopping different sets of printing mechanism independently, means for coupling together certain of said sets of printing mechanism, a plurality of folding mechanisms arranged one above another, and means for driving said folding mechanisms independently of one another and in combination with different sets of printing mechanism.”
“IT. The combination of a number of double-width web-presses arranged one above another and each perfecting its own webb, and more than two independent folding, cutting, and delivering mechanisms placed at one end of said presses and arranged with one pair thereof side by side on one level or plane,, and the remainder on a different level or plane, and all said' mechanism in one vertical plane.”
“32. In a printing-press, the combination with a plurality of' sets of printing mechanism, of driving devices at each side of' the press, and independent driving-shafts for driving the same; *310set or sets of printing mechanism from opposite sides of the press.
“33. The combination with a set of printing mechanism of a plurality of folding mechanisms and means for operating said folding mechanisms independently of one another from and in combination with the printing mechanism.
“34. The combination with a plurality of sets of printing mechanism, of a folding device, and means for driving said folding device from and in combination with different sets of printing mechanism operating separately.
“35. In a printing-press, the combination of three or more sets of printing mechanism arranged one above another in a common frame and capable of operation as distinct and independent presses, means for coupling together certain of said sets of printing mechanism, and means for starting and stopping said coupled sets and the other set or sets of printing mechanism independently of each other.
“36. In a printing-press, the combination of a plurality of sets of printing mechanism, means for starting and stopping certain sets of printing mechanism independently, a plurality of folding mechanisms, and means for driving said folding mechanisms independently of each other and in combination with different sets of printing mechanism.”
Of these seven claims that numbered II was rejected on the ground of its anticipation by an English patent issued in 1889 to Henry Edward Newton; and the other six were rejected on the ground that they, each and all of them, comprised new matter not disclosed in the original application. All the tribunals of the Patent Office concurred in this rejection; and the applicant has now appealed to this court.
1. In reference to claim No. II no very great consideration of the matter is required from us. In fact, it is not very seriously pressed by the applicant; and it is very clear that it was anticipated by the patent to Newton. It only differs from one of the claims of that patent by the duplication of the mechanism employed. One set of mechanism is shown in the English patent; two sets of the same or similar mechanism one above the *311■other are shown in this claim No. 17, without any new result from the collocation other than that perhaps of greater convenience. But duplication is not invention unless by the combination a new or better result is evolved. It is no more than a mechanical process that does not require the inventive faculty for its development.
2. But a different question is presented by the other six claims of the appellant. These have been rejected, as already stated, on the ground that there is no foundation for them in the ■original application; that they are not disclosed in the specifications or drawings of that application; and that they are new matter injected into the application, for which there is no warrant. As we understand the position of the office, it is to the effect that, while amendment of claims and the introduction ■even of new claims are freely allowed, provided that they are disclosed and there is a proper basis for them in the original specifications or drawings, yet no such amendment or addition shall be allowed when the proposed amendment or addition involves new matter not so disclosed in the original application. And this position undoubtedly is fully sustained by the adjudications in the cases of Chicago & N. W. R. Co. v. Sayles, 97 U. S. 554, 24 L. ed. 1053, Bechman v. Wood, 15 App. D. C. 484, and other cases in this court. The reason for the rule is that intervening rights may have accrued which may be greatly affected by the allowance of such amendment or addition, as indeed would very clearly be the case in the present instance, inasmuch as the very claims in question had been patented to Goss during the pendency of the present application. We understand, also, that an applicant advancing such claims is not precluded from presenting them in a new and distinct application, if he so desires.
If the action of the Patent Office in the premises were to be regarded merely as the exercise of the power, which it undoubtedly possesses, to allow or refuse amendment with proper judicial discretion, it might be questioned whether this court had authority to review such discretionary exercise of power. But it has been the usage of the Patent Office to treat the question *312here involved as one of substantial right, and to pass upon it as upon the question of patentability itself; and it may be that, under the decision in the case of United States ex rel. Steinmetz v. Allen, 192 U. S. 543, 48 L. ed. 555, 24 Sup. Ct. Rep. 416, a party has the right to insist upon the final determination of' the question in the application under which he raises it. At all! events, no question of jurisdiction is made here, and none need be considered.
Passing, tlien, to the consideration of the appeal upon its merits, we find, after a careful consideration of the record and of the briefs and arguments of counsel, that no sufficient reason has been shown for the reversal of the action of the Acting Commissioner of Patents. To the careful and most elaborate opinions rendered in the case by the tribunals of the Patent Office, although they differ in some particulars, it would serve no good purpose to add another, and to examine the details of the applicant’s claims in their technical aspect with reference to the-original specifications and drawings, inasmuch as we approve-those opinions and the results which they reach. We may, however, properly add one or two considerations to what they have-said.
With reference to claim No. 9, one of its most important features, indeed the feature which made the claim patentable toGoss, is that of “means for driving said folding mechanisms independently of one another and in combination with different, sets of printing mechanism,” which is wholly wanting in the applicant’s original specifications. In these the several sets of printing mechanism each combine with only one folder. This is a radically different form of construction.
So in claim No. 35 there is call for “three or more sets of printing mechanism arranged one above another and capable of operation as distinct and independent presses,” while in the original application the claim was confined to two sets. Now, the difference either is or is not a patentable novelty. If the-change is an obvious one which would occur to anyone, it is not patentable. If it is not obvious, then there is no disclosure of it in the original specifications.
*313Claim No. 32 calls for “independent driving-shafts for driving the same set or sets of printing mechanism from opposite-sides of the press,” while in the original specifications there was only one driving-shaft for each set. Claim No. 33 includes “means for operating the folding mechanisms independently of one another from and in combination with the printing mechanism,” while the original disclosure was of folders which could, not be operated from the printing mechanism. The same objection holds to claim No. 34; and claim No. 36 is not substantially different from claim No. 9, and is subject to the same-objection.
We do not see that there was any error in the ruling of the Acting Commissioner, and we think that his decision should be, and it is hereby, affirmed.
The clerk will certify this opinion and the proceedings in this court in the premises to the Commissioner of Patents, according to law. ■ Affirmed.
