From a decision holding it estopped to deny the validity of a design patent, and finding infringement,' the defendant below appeals. The patent in suit is design patent No. 84,811, issued August 11,1931, to R. De Boer. It is for an ornamental design for a combination ash receiver and electric lighter “substantially as shown” in two drawings, one of a front elevational view of the combination, and the other of its side elevational view. The main utilitarian purpose of the device is for installation in automobiles. There is disclosed a supporting back plate, a semi-cylindrical ash receptacle attached to its wide iipper portion, and a forwardly projecting electric lighter mounted on the narrower lower portion, which has downwardly and inwardly curved sides, and a curved lower end.

The claim of estoppel is based upon tbe following facts: At tlie time application was made for the patent, the designer, Rudolph De Boer, was in ilie employ of the plaintiff, a.nd assigned the application to his employer. Prior to issuance of the patent De Boer resigned, organized the defendant company, became the owner of three-fourths of its capital stock and its president. In view of those circumstances the court below held the defendant corporation subject to any estoppel which might exist against the patentee. Siemens-Halske Electric Co. v. Duncan Electric Mfg. Co. (C. C. A.)
As to whether an estoppel existed as against De Boer, this court in Westinghouse Electric & Mfg. Co. v. Formica Insulation Co.,
For our present purpose the limitation put by the Supreme Court -upon the extent of the estoppel asserted against the assignor in the Westinghouse Case is sufficiently clear to point the way to decision. Concluding, in spite of a number of decisions contra, , that Judge Burton for this court in Noonan v. Chester Park Athletic Company,
In the instant ease the District Court found infringement in two designs put forth • by the defendant. It had before it the prior art, but whether the precise invention, or in other words, the scope of the patent, was considered, is not clear; the court merely holding that the resemblance was such as to deceive the ordinary observer, and the similarity so substantial as to result in confusion to prospective purchasers, applying the language of Gorham Manufacturing Company v. White, 14 Wall. (81 U. S.) 511, 530,
It has been held, however, that a design patent stands on as high a plane as utility patents, Knapp v. Will & Baumer Co.,
So viewing the test that is to be applied on the issue of infringement, it appears to us that while there is some similarity between the patented and alleged infringing designs, which without consideration of the prior art might seem important, yet such similarity as is due to common external configuration is no greater, if as great, between the patented and challenged designs as between the former and the designs of the prior art. The article patent to Metzger, No. 1,543,290, issued June 23, 1925, and the first design patent of De Boer, No. 79,348, issued September 3, 1929', both diselose a baekplate, the upper portion of which is comparatively wide and has attached thereto a receptacle for ashes, and the lower portion of which is narrowed by curving side ' edges to a circular downward extension ae- ' commodating a cylindrical forwardly extending lighter. There are differences of course in lines and curves between the outer configuration of the patented design and those noted in the prior art, hut such differences are no greater than those that exist between the patented design and the -alleged infringing i • n n. vta « it a a *a designs. Conceding validity to the patent, it is quite clear it is entitled to a very limited interpretation, and that so limited the^ defendant’s designs do not infringe. The ash tray of the patented design is semi-cylindrical, that of the defendant’s first structure is semi-octagonal, and that of its second is a combination of three connected arcuate portions. The defendant’s devices are ornamented with fluted or beveled designs not at all found in the .drawings of the patent, and the narrowing of the baekplate to accommodate the lighter is accomplished by downward and outward curves, rather than by the downward and inner curves of the patent. There are also other differences in detail not necessary to note, We are quite aware that similarity is not to be determined by making too close an analysis of detail, yet where in a crowded art the conaposite of differences presents a different impression to the eye of the average observer (as above defined), infringement will not be found.
Another consideration contributes to our conclusion that there is no infringement. The patented design is comparatively simple, and -without ornamentation. In the main its configuration is made imperative by the elements which it combines and by the utilitarian purp0se of the device. It was certainly not the intent of the law to grant monopoly to purely conventional design which is in itself little more than a necessary response to the purpose 0f the article designed. The scope of a design patent, as well as its originality, must depend on something more than this. As was said by this court in Standard Computing Scale Company v. Detroit Automatic Scale Co.,
Some point is made of confusion on the part of purchasers between the defendant’s devices and those of the plaintiff. The evidenee on this subject is not impressive. We have seen the patented articles and those alleged to infringe, and as was said by Judge Donahue, in the Standard Computing Seale Company Case, supra, with Judges Knappen and Denison concurring: “Oral evidence is never so satisfactory as the judgment of the eye, upon actual view of the original design patent and the one claimed to be an infringement thereof.” Compare, also, Whiting Manufacturing Company v. Alvin Silver Company,
We conclude that granting the validity of the patent as the necessary consequence of a conceded claim of estoppel, but not deciding the issues as to either, the defendant’s designs do not infringe.
The decree below is reversed, and the ease remanded for further proceedings consistent herewith.
