Opinion

VAN VALKENBURGH, Circuit Judge.

May 20, 1919, letters patent No. 1,304,028 were issued to one Emory Crouse; this patent is now the property of appellee, a Kansas corporation having its principal office and place of business at Wichita in that state. The patent was for a |gasoline dispensing device. The object of the invention, so far as is pertinent to this inquiry, is thus stated in the specification:

“This invention relates to liquid dispensing devices, particularly to those of the type adapted for dispensing gasoline and has for its object the provision of a device embodying a transparent receptacle, graduated throughout its length, into which the gasoline is first pumped and then subsequently withdrawn; the quantity drawn off being easily seen by the purchaser upon observing the difference in the levels of the liquid within the transparent receptacle, this arrangement preventing fraudulent measurement by the dealer.

“An important object is the provision of a device of this character provided with means whereby the initial quantity of liquid within the transparent receptacle will always be the same, and be automatically regulated, any excessive amount pumped thereinto automatically returning to the storage tank with which the device is associated.

“A further object is the provision of a device of this character provided with means whereby all the gasoline may be drained back into the storage tank, and whereby the various portions may be drained sepa *436 rately, in order that sediment may be removed.”

The single claim of the patent reads thus:

“A liquid dispensing device comprising a transparent container provided with graduations, a member disposed below and communicating with said container, a pipe extending through said member in spaced relation to the walls thereof to provide an annular chamber and extending into and terminating at the upper portion of said container, a valved discharge pipe communicating with said chamber, a supply pipe communicating with said chamber, means for supplying liquid under pressure into said supply pipe, and an overflow pipe communicating with said first-named pipe, and valved means establishing communication between said chamber and said last-named pipe.”

Some time after this patent was issued, appellants began the manufacture of a gasoline pumping device which omitted the annular chamber, described and emphasized as an element in the specification and claim of the patent in suit. Appellants’ first pump was completed in September, 1920. In July of that year appellants began to build a factory and to install the necessary machinery in the city of Wichita for the purpose of manufacturing and selling to the public generally their said dispensing device, of which appellee complains. On or before February 8, 1921, appellants had in operation a factory of substantial capacity, with ten salesmen selling their output throughout the states of Kansas, Oklahoma, and Illinois. A considerable number of orders had been taken, and a substantial number of pumps had been manufactured and shipped.

February 8, 1921, appellee filed its application for a reissue patent, which was granted, and the reissue made, on August 22, 1922. The reissue patent was identical with the original in specification and drawings. It contained six claims; the fifth being the same as the single claim of the original patent. The object of the reissue was to cover all forms of structure which might be included within the scope of the original invention. The first four claims of the reissue patent omitted as an element the annular chamber specified in claim 5, and in the one and only claim of the original patent. Shortly after the reissue this suit was filed. While the bill charges infringement of the reissue patent only, it is strongly contended that the original patent likewise is infringed.

As has been stated, the original patent was issued May 20, 1919. The application for reissue was filed February 8, 1921, and the reissue made August 22, 1922. It will thus be seen that the application for reissue was made nearly 21 months after the issuance of the original patent. . The defenses are: First, invalidity; second, noninfringement. They will be considered in their inverse order. Both the master, to whom the ease was referred, and the trial court, found the patent to be valid, and that appellants’ device infringed the single claim of the original patent, and also the first five claims of the reissue patent. In appellants’ structure a prominent element of claim 1 of the original patent and claim 5 of the reissue is omitted; this is the annular chamber underlying a member disclosed below and communicating with a superimposed graduated container. It is conceded that this annular chamber is a specified member and element in the claim of the original patent; but it is contended, as the fact is, that the owner of the patent, even before the reissue, had abandoned that construction, and that the annular chamber is not essential to the operation of the patented device.

It is true that nowhere in the specification is this annular chamber described as discharging any function, except to form a receptacle into which, and from which, certain drain pipes pass. In fact, the transparent container, the member disclosed below and communicating with said container, and this annular chamber, all open one into another, and contain the gasoline pumped up from the reservoir. It is the contention of the appellee that the second of these three members, described in the specification as an upwardly flaring casting, upon the upper edge of which rests the cylindrical member of glass, or transparent container, is the equivalent, or, at least, satisfies the claim and function, of the annular chamber; that defendants’ device has this upwardly flaring easting, and in other respects is the same, under the doctrine of equivalents, as the patented device. It is conceded by appellants that their machine is covered by claim 1, and perhaps by other claims, of the reissue, but not by claim 5, nor by the claim of the original patent, because of the omission of this annular chamber.

Appellee is confronted at the outset by the rule announced by Mr. Walker in his work on Patents (5th Ed.) par. 349:

“Omission of one element or ingredient of a combination covered by any claim of a patent averts any charge of infringement based on that claim, whether or not the omitted ingredient was essential to the combinar *437 tion of the patent,- and whether or not it was necessary to the operativeness of the device; and it makes no difference that another element is made to do the work of itself and of the omitted element. A combination is an entirety. If one of its elements is omitted, the thing claimed disappears. Every part of the combination claimed is conclusively presumed to be material to the combination, and no evidence to the contrary is admissible in any case of alleged infringement. The patentee makes all the parts of a combination material, when he claims them in combination and not separately.”

This text, which states the best known and most frequently applied of all the rules which pertain to infringement, is overwhelmingly supported by the eases. Prouty v. Ruggles, 16 Pet. 336, 341, 10 L. Ed. 985; Signal Co. v. Signal Co., 114 U. S. 87, 5 S. Ct. 1069, 29 L. Ed. 96; Fay v.
