Opinion

DENISON, Circuit Judge.

, Infringement suit upon patent No. 1,196,691’ ?ssued Au§ust 29 > 1916> toT Hopkins, for a PS-mt^-P^ying apparatus. In 1924, Hop-tins began suit on this patent in California against one Mohr, who was using what is known in this record as the first form of apparatus manufactured by the De VilbissCompany, of Toledo, the defendant and appellee herein. It assumed the defense of theMohr Case, with the knowledge of plaintiff, There was a decree in plaintiff's favor, entered in .1925 and affirmed by the Ninth Circuit Court of Appeals in 1926. 14 F.(2d) 793, affirmed 14 F.(2d) 799. The plaintiff' in tbat case and this, the owner of the Hopkins patent, then brought this suit against theDe Vilbiss Company at Toledo. After theMohr suit it had been making the forms- *669 known as its second and third. The court below held that these two forms did not infringe the patent, and that plaintiff’s right to accounting and for damages for the manufacture of the first form had been lost by laches and because plaintiff had used unfair means in the assertion against the trade of its rights based on that decree. The court below further held that defendant was entitled to an injunction against such unfair means and an accounting of its damages caused thereby.

The De Vilbiss Company does not deny that it was privy to the California suit, and that the decree therein is an adjudication concluding it as to the validity of the Hopkins patent and its infringement by the first form. It is, however, clear that the scope of the Hopkins patent, as extending its monopoly beyond the first form, and the specific questions of infringement by forms two and three were not involved or decided in that case, and are therefore now open.

Since the original decree in California, and in subsequent suits brought by plaintiff against Ford and the Roman Company, the Ninth Circuit Court of Appeals has decided that forms similar to 2 and 3 are not infringements. 31 F.(2d) 278, 279. The same result has been reached by the Eighth Circuit Court of Appeals in the Matthews Case, 40 F.(2d) 879, decided April 5,1930. The point is so well discussed in the master’s report, which was the basis of the Ford and Roman decisions, and in Judge Stone’s opinion in the Eighth Circuit Court of Appeals, that we can add little, and will not take the space for a detailed discussion of the facts. We concur in the results reached by these two courts on this subject. 1

The question turns on the meaning of the mutual independence of the two air valves called for in the claim. Upon the face of the specification and claims, infringement can plausibly be asserted, for within a certain range of operation (a range perhaps covering the ordinary practical field) the two valves in forms 2 and 3 are mutually independent ; but the file wrapper strongly indicates that Hopkins had in mind a more complete independence; and — more important in our view — to give the broad construction necessary to make out infringement by forms 2 and 3 would seem to include prior art structures and thus invalidate the claims.

Hopkins interposed in each of his lines moans for reducing or controlling the air pressure. In his specifications he refers to-this as a “reducer,” or an “air reducer.” He does not specify what form this reducer shall take, except as in his drawing numerals. 6 and 9 indicate, merely conventionally, what he calls in one ease a reducer and in the other case a reducing valve. With each of these he shows a gage “for the purpose of observing the pressure passing through.” In the claims, this element is described as “controllable reducing means,” “controlled reducing means,” “a pressure regulator,” or “means to vary the pressure.” These terms are all very general, and plainly cover such regulating valve or relief or controlling valve as was in common use upon the main air line after it left the' original or main compressor or pressure tank or on the tank itself. To construe Hopkins’ claims as covering a device where a reducing valve, anywhere on the main line above the branching point, controlled all the air pressure, and when there was in addition only a controlling valve on the branch leading to the paint tank, would make the claims read upon the old art. It is therefore necessary to the validity of the patent that the “independent control” of the claims should he construed as referring to a completely independent control, so that neither one, no matter how varied, can affect the other.
