Opinion

MeKENNAN. Circuit Judge.

The bill in this case sets up two patents, numbered 2570 and 2571. They are divisions and re-issues of letters patent [No. 13,057] granted to George Thompson, October 21st, 1850, and have been extended for seven years from October 21st. 1S70. The complainants now move for a preliminary injunction to restrain the alleged infringement oi 2571. They have shown the possession and enjoyment of the exclusive rights, secured by this patent, for upwards of fifteen years, and that its validity has been established by litigation in the circuit court for this circuit, in several cases determined in 186S and 1S71. Penn. Salt Manuf’g Co. v. Thomas [Case No. 10.050]. decided October 2d, 1871. In the face of these facts, the affidavits presented by the respondent, denying the novelty of the invention claimed, cannot have the effect of impugning the complainants’ title. So far as concerns the present motion, it must be treated as established.

The respondent has been engaged in the sale only of an article, enclosed in small metal cans, with printed labels on them, marked “Compound Condensed Lye,” and thus he is alleged to have infringed the complainants’ patent. He denies that the substance thus enclosed is caustic alkali, or that, as it is put up and prepared for the market, it is within the scope of the patent. If this denial is true, in either of its branches, the respondent is not an infringer.

The claim of the patent in question is for “caustic alkali, encased or enveloped in a tight metallic integument or metallic casing, substantially as described” in the specification. And it is thus described: “I have discovered that by enclosing or encasing caustic alkali tightly in metallic integuments or casings, the deliquescence may be prevented,, and the caustic alkali may be preserved practically for any length of time, and transported without destruction or accident. When it is desired to prepare the article for family use only, I enclose in each metallic integument or casing such quantity of caustic alkali as it would be desirable to use in a family at each single occasion. And one mode which I adopted and found to answer-, well for enclosing the material in a metallic integument is to.provide boxes or canisters of sheet iron, or other material, made tight at the joints with infusible cement or otherwise, and into these I force the caustic alkali in a molten state, until they are nearly or quite full. The lid is then pressed down, so as to exclude air or moisture, and is secured by cement or otherwise.” The invention then consists of these constituents: 1st-Caustic alkali. 2d A metallic integument to. enclose it, of such size as will contain a quantity of the alkali, which it may be “desirable to use in a family at each single occasion,” and made air-tight by infusible cement, or other equivalent means.

Does the article shown to have been sold by the respondent embody these constituents of the complainants’ invention? -The substance contained in the cans is alleged to be a compound, produced by the thorough incorporation with the caustic alkali of oil and rosin, by which it is “rendered independent of any need for the exclusion of the air from it.” The mode of putting it up is stated to be, first, to pour into the can a-small quantity of oil or rosin, and then melted caustic alkali and oil, or oil and rosin, in alternate layers, until the can is nearly full, when the whole is stirred and mixed, is al-. lowed to cool, and a finishing layer of oil and rosin is then poured on the top. This, it is claimed, is a substance materially different from the “concentrated lye” put up by the complainants, under their patent. The proofs presented on both sides do not sustain this position of the respondent. Taken altogether, they satisfactorily show», that tne substance contained in the respondent’s cans is caustic soda, with oil or rosin mechanically distributed through it. but not in chemical union with it. This is the result of careful analysis, and it is confirmed by the prompt [1054]*1054and palpable deliquescence of the contents of some of the cans, which were opened and exposed to the atmosphere during the hearing of this motion. And this is still further confirmed by the known incompatibility of these elements, without the presence of water. This “compound” then consists chiefly of caustic soda with oil and rosin intermixed, but not combined so as to form a new substance, or to change the peculiar properties of the alkali. Deriving its distinctive character from caustic soda — its predominant constituent — it must be regarded as substantially caustic soda. We have here then all the elements of the complainants’ invention, viz.: Caustic soda, enclosed in a metallic integument, containing a quantity adapted to family use at one time, and secluded from the atmosphere by an impermeable cement.

It is urged, however, that the mode of excluding the air is essentially different from that indicated in the complainants’ patent. The argument is perhaps more pertinent to another patent, set up in the bill, but not involved in this motion, than to the patent in question, which is for a product only, but it is not unworthy of a brief notice. In his specification, the patentee, as he was bound to do, describes a method of effectuating his invention, and he proposed to effect the exclusion of the a'>- by the application of in-fusible cement to the joints of the cans, and by pressing down the lids and securing them by infusible cement or otherwise. But he does not limit himself to the use of infusible cement, or prescribe its exterior application as essential tc the production of his invention. The specific object of the use of cement is to exclude the air. Obviously, then, it is its impermeability, not its infusibility, which is made available for that purpose. An infusible cement applied on the outside of the caD may be of additional utility, but it does not- change the fact, that the avowed and essential function of the cement is to protect the caustic soda from the effect of exposure to the air. Any method, analogous to that descnbed in the specification, by which this is accomplished, is within the scope of the patent, and where there is this substantial identity of means and result, it is immaterial what sort if cement is employed, or whether it is applied inside or outside of the integument. There is no substantial difference in the product.

An objection is made to the allowance of the motion, founded upon an alleged material defect in the complainants’ bill. The patent in question is one of the divisions of a re-issue of the original patent, and it is maintained that the bill must aver that each division was for a distinct invention. That a patent may be re-issued in • divisions is unquestionable. By the act of 1880 and its sequents, the commissioner of patents is authorized, when a re-issue is applied for, to grant several patents for “distinct and separate parts of the thing invented.” Whether the “thing invented” is susceptible of division into “distinct and separate parts” rests, primarily at least, in the judgment of the commissioner. When he has so decided, every presumption is in favor of the rightful exercise of his authority. This is a familiar rule, and has been often applied to the decisions of the commissioner. The re-issue of a patent then, in divisions, carries with it the intendment that the invention described in the original consisted of “distinct and separate parts.” And it follows, that an averment in the bill that several re-issued patents were granted to the patentee imports also an averment that the invention consisted of “distinct and separate parts,” and is prima facie sustained by the exhibition of the said patents alone.
