Opinion

KILLITS, District Judge

(after stating the facts as above). In our opinion a determination of the issue of infringement raised by the pleadings requires but a few simple deductions from the record, principally from the terms of the Hopkins patent and the history of its prosecution shown in the file wrapper contents.

So far as this case is concerned, we are not now privileged to go into the general question of validity of the Hopkins patent; for we find from the record that the defendant here, the De Vilbiss Manufacturing Company, became so connected with the defense in actions brought by the present plaintiff in the District Court of the Northern District of California against J. A. Mohr & Sons and the Standard Oil Company, that the decisions in those cases (14 F.[2d] 793, 800, inclusive) bind it respecting structures manufactured by it prior to 1925. A careful examination of those cases, however, leads to the clear conclusion that neither involved nor brought about an adjudication of the question whether infringement of the Hopkins patent (1,196,691) here sued on was occasioned by defendant in the instant ease in its manufactures subsequent to 1924, and represented by defendant’s structures Nos. 2 and 3, of which plaintiff complains in this action. Indeed, these structures were not before the western court in either case. No manufacture and sale of either was begun until after the (Mohr and Standard Oil Cases were under way.

We wish our position to be made clear to the end that it may not be said that in any degree does this court either adopt or reject the decision of the California court respect[532]*532ing validity of the Hopkins patent. We take that matter as closed here only as affecting defendant’s earlier manufacture, against which the California actions were directed, and because of the relation to those cases charged to the defendant by the California courts. In effect, therefore, the parties here are thé same as in the western cases. Were the circumstances otherwise, we would, of course, resort to the California decisions as aids in elucidating the question at issue, and not decisive thereof, leaving us free to our own conclusions as to the force of the prior art, and possibly to give a different effect thereto, according to whatever judgment we should reach.

Collings and Weatherhead patent, No. 412,875, shows a combination of elements which is in apparent anticipation of the Hopkins specifications, and was urged as an effective defense in the California cases. It, however, is a device for spraying fuel oil into a furnace, and was discarded by the courts as a pertinent anticipation in the Mohr and Standard Oil Cases, on the theory that the arts of spraying fuel oil and of spraying paint were not analogous. ‘ Those courts, however, did not have before them a patent brought to our attention (Bryce, No. 520,766) whose specifications declare such analogy to exist. Bryce’s invention was a device offered as effective to “spray fine dry solids, or liquids, or both, by the force of dry vapor” and applicable to “mechanical painting” or to “inject, under air or other vapor pressure, solid and liquid fuel into a furnace.”

Were, therefore, the question of validity open between the parties to this case, we would have the liberty, now denied us by the California eases, to consider the function of the Bryce disclosure, not present to them, and also, possibly, our discussion of á somewhat similar question of analogy in the matter of the Painter patent, No. 638,354. Crown Cork & Seal Co. v. Sterling Cork & Seal Co. (D. C.) 210 F. 26, 31, affirmed as to the decided invalidity of the Painter patent (C. C. A.) 217 F. 381. In such a possible reconsideration of validity, the position in the prior art of Collings and Weatherhead might become more important.

Coming now to plaintiff’s claim that defendant’s structures 2 and 3 infringe the Hopkins patent, .granted August 29, 1916, No. 1,196,691, it is unnecessary to enter an extensive discussion of the state of the art when the application was made for alleged improvements in “means for distributing liquids.” This was rejected at first by the primary examiners on Fisher, No. 584,864, and Quest et al., No. 627,877. Upon rehearing, and noting the emphasis placed by Hopkins and his counsel upon the feature of two automatic pressure valves, one in each of two branch lines to the spraying nozzle, which was pressed as the essence of the alleged invention, claim 1 was allowed, other claims being rejected, and that action sustained by a majority of the general examiners on the theory of equivalency of automatic regulators with hand valves shown in the prior art. As will be noted later, the commissioner sustained these .claims, but not to enlarge the scope of the invention beyond that urged by applicant as the reason for reconsideration of the primary rejection on Fisher and Quest, resulting in the allowance of claim 1. That the commissioner viewed this as availing yet but a slight and special advance in the art, limited to a certain specified construction, is shown by this quotation from his opinion:

“Applicant’s apparatus differs from the prior art in using two automatic valves, one between the supply of compressed air of the paint tank, and the other in the branch conducting the air to the nozzle.”

Nowhere may it be said that the effect of the prior art, which made the limitations on the first claim acceptable as inventions, was not equally applicable to the remaining claims which the commissioner approved.

Not only did this Hopkins patent gain allowance upon final appeal because of the distinction from the prior art noted by the commissioner above quoted, but repeatedly in specification, argument before .the examiners from the beginning, and briefing on the appeals, was that emphasized as the sole criterion of patentability. Invention, it was claimed in varying terms, lay only, but decidedly, in the fact that Hopkins employed two automatic valves, definitely located in the two branches from the air supply line, which were capable of independent adjustment and operation; one regulating the pressure upon the liquid in the paint container, and the other in the air line leading to the nozzle, where the branches came together and the pressures co-operated in producing a satisfactory spray upon the object to be painted. In neither of the defendant’s structures involved in this action is there such construction, nor one which will accomplish the result which Hopkins elaims, in his application and its prosecution, is peculiar to his invention. The defendant has, of course, the two branch lines which are necessary to a successful apparatus, and which were old in the art; but one of these, however — that into the [533]*533paint container only — is equipped with a pressure regulator; the other carrying to the nozzle, to effect the spraying, only air under the pressure raised in the common source of supply. These constructions therefore, in our judgment, are nothing more' than those advised by the art as old before Hopkins’ alleged invention; for it was old in the art and a matter of common use, in fact essential to the successful working of any apparatus, including the Hopkins construction, that the source of supply should be from air under pressure. The Hopkins patent speaks of “a suitable source of supply” as fundamental to the working of his invention, and he says that that means a supply of air under regulated pressure — an old combination • element, one which he himself had used prior to his invention.
