Section 4929 of the Revised Statutes provides that 'any person who, by his own industry, genius, efforts, and expense, has invented and produced any new and original design for a manufacture, bust, statue, altorelievo, or bas-relief; any new and original design for the printing of woolen, silk, cotton, or other fabrics; any new and original impression, ornament, pattern, print, or picture to be printed, painted, cast, or otherwise placed on or worked into any article of manufacture; or any new, useful, and original shape or configuration of any article of manufacture,—the same not having been known or used by others before his invention or production thereof, or patented or described in any printed publication, may, upon payment of the fee described, and other due proceedings had, the same as in cases of inventions or discoveries, obtain a patent therefor.'

The first three of these classes plainly refer to ornament, or to ornament and utility, and the last to new shapes or forms of man ufactured articles; and it is under the latter clause that this patent was granted.

In Manufacturing Co. v. White, 14 Wall. 511, 524, it was said by this court, speaking through Mr. Justice Strong, that the acts of congress authorizing the granting of patents for designs contemplated 'not so much utility as appearance, and that, not an abstract impression or picture, but an aspect given to those objects mentioned in the acts. * * * And the thing invented or produced, for which a patent is given, is that which gives a peculiar or distinctive appearance to the manufacture or articles to which it may be applied, or to which it gives form. The law manifestly contemplates that giving certain new and original appearances to a manufactured article may enhance its salable value, may enlarge the demand for it, and may be a meritorious service to the public. It therefore proposes to secure for a limited time to the ingenious producer of those appearances the advantages flowing from them. Manifestly the mode in which those appearances are produced has very little, if anything, to do with giving increased salableness to the article. It is the appearance itself which attracts attention, and calls out favor or dislike. It is the appearance itself, therefore, no matter by what agency caused, that constitutes mainly, if not entirely, the contribution to the public which the law deems worthy of recompense.' This language was used in reference to ornamentation merely, and, moreover, the word 'useful,' which is in section 4929, was not contained in the act of 1842, under which the patent in Manufacturing Co. v. White was granted; so that now, where a new and original shape or configuration of an article of manufacture is claimed, its utility may be also an element for consideration. Lehnbeuter v. Holthaus, 105 U. S. 94.

But, as remarked by Mr. Justice Brown, then district judge of the eastern district of Michigan, in Northrup v. Adams, 12 O. G. 430, 2 Ban. & A. 567, which was a bill for the infringement of a design patent for a cheese safe, the law applicable to design patents 'does not materially differ from that in cases of mechanical patents, and 'all the regulations and provisions which apply to the obtaining or protection of patents for inventions or discoveries * * * shall apply to patents for designs.' Section 4933.' And he added: 'To entitle a party to the benefit of the act, in either case there must be originality, and the exercise of the inventive faculty. In the one there must be novelty and utility; in the other, originality and beauty. Mere mechanical skill is insufficient. There must be something akin to genius,—an effort of the brain as well as the hand. The adaptation of old devices or forms to new purposes, however convenient, useful, or beautiful they may be in their new role, is not invention.' Many illustrations are referred to,—as, for instance, the use of a model of the Centennial building for paper weights and ink stands; the thrusting of a gas pipe through the leg and arm of the statute of a shepherd boy, for the purpose of a drop light; the painting upon a familiar vase of a copy of Stuart's portrait of Washington, none of which were patentable, because the elements of the combination were old. The shape produced must be the result of industry, effort, genius, or expense, and new and original as applied to articles of manufacture. Foster v. Crossin, 44 Fed. Rep. 62. The exercise of the inventive or originative faculty is required, and a person cannot be permitted to select an existing form, and simply put it to a new use, any more than he can be permitted to take a patent for the mere double use of a machine. If, however, the selection and adaptation of an existing form is more than the exercise of the imitative faculty, and the result is in effect a new creation, the design may be patentable.

In Jennings v. Kibbe, 10 Fed. Rep. 669, 20 Blatchf. 353, Mr. Justice Blatchford, when circuit judge, applied the rule laid down in Manufacturing Co. v. White, supra, atating it thus: That 'the true test of identity of design is sameness of appearance,—in other words, sameness of effect upon the eye; that it is not necessary that the appearance should be the same to the eye of an expert, and that the test is the eye of an ordinary observer, the eyes of men generally, of observers of ordinary acuteness, bringing to the examination of the article upon which the design has been placed that degree of observation which men of ordinary intelligence give.' Ripley v. Glass Co., 49 Fed. Rep. 927.

In this case it appeared from the evidence that among other trees and saddles that were old in the prior art was one called the 'Granger' tree, which had a cut-back pommel, and a law, broad cantle, and was well known; and another called the 'Jenifer tree,' or 'Jenifer-McClellan' saddle, which was also well known, and had a high, prominent pommel, and a high-backed cantle, or hind protuberance, in the shape of a duck's tail.

The exhibits embrace, among others, a slotted Granger saddle, the Jenifer-McClelland, the Sullivan-Black-Cranger tree, and the saddle sold by defendants; the latter being substantially the Granger saddle with the Jenifer cantle.

The saddle design described in the specification differs from the Granger saddle in the substitution of the Jenifer cantle for the low, broad cantle of the Granger tree. In other words, the front half of the Granger and the rear half of the Jenifer, or Jenifer-McClellan, make up the saddle in question, though it differs also from the Granger saddle in that it has a nearly perpendicular drop of some inches at the rear of the pommel, that is, distinctly more of a drop than the Granger saddle had.

The experienced judge by whom this case was decided conceded that the design of the patent in question did show prominent features of the Granger and Jenifer saddles, and united two halves of old trees, but he said: 'A mechanic may take the legs of one stove, and the cap of another, and the door of another, and make a new design which had no element of invention; but it does not follow that the result of the thought of a mechanic who has fused together two diverse shapes, which were made upon different principles, so that new lines and curves and a harmonious and novel whole are produced, which possesses a new grace, and which has a utility resultant from the new shape, exhibits no invention.' And he held that this was effected by the patentee, and that the shape that he produced was, therefore, patentable. But we cannot concur in this view.

The evidence established that there were several hundred styles of saddles or saddletrees belonging to the prior art, and that it was customary for saddlers to vary the shape and appearance of saddletrees in numerous ways, according to the taste and fancy of the purchaser. And there was evidence tending to show that the Granger tree was sometimes made up with an open slot and sometimes without, and sometimes with the slot covered and padded at the top and sometimes covered with plain leather; while it clearly appeared that the Jenifer cantle was used upon a variety of saddles, as was the open slot. Nothing more was done in this instance (except as hereafter noted) than to put the two halves of these saddles together in the exercise of the ordinary skill of workmen of the trade, and in the way and manner ordinarily done. The presence or the absence of the central open slot was not material, and we do not think that the addition of a known cantle to a known saddle, in view of the fact that such use of the cantle was common, in itself involved genius or invention, or produced a patentable design. There was, however, a difference between the pommel of this saddle and the pommel of the Granger saddle, namely, the drop at the rear of the pommel, which is thus described in the specification: 'The pommel, on its rear side, falls nearly perpendicularly for some inches, when it is joined by the line forming the profile of the seat. The straight inner side of the pommel (marked b) is joined at c by the line, C, of the seat.' The specification further states: 'The line from the front of the pommel, B, inclines outward for some distance in a nearly straight line, m, before being rounded toward the rear to join the line, h, at the point where the stirrup strap is attached, to thus define the bottom line of the saddle, the outline given by line, m, from the pommel being the general form of the English saddletree known as the 'cut back." The shape of the front end being old, the sharp drop of the pommel at the rear seems to constitute what was new and to be material. Now, the saddles of the defendants, while they have the slight curved drop at the rear of the pommel, similar to the Granger saddle, do not have the accentuated drop of the patent, which 'falls nearly perpendicularly several inches,' and has a 'straight inner side.' If, therefore, this drop were material to the design, and rendered it patentable as a complete and integral Whole, there was no infringement. As before said, the design of the patent had two features of difference as compared with the Granger saddle,—one the cantle, the other the drop; and unless there was infringement as to the latter there was none at all, since the saddle design of the patent does not otherwise differ from the old saddle with the old cantle added,—an addition frequently made. Moreover, that difference was so marked that in our judgment the defendant's saddle could not be mistaken for the saddle of the complainant.

There being no infringement, the decree must be reversed, and the cause remanded, with a direction to dismiss the bill, and it is so ordered.
