Opinion

AUGUSTUS N. HAND, Circuit Judge.

This is an appeal from a final decree awarding the plaintiff profits arising from sales of stencil sheets by the defendant which were held to have infringed U. S. Letters Patent No. 1,526,982. Claims 2, 3, 4, 6, 7, 11, 16, 18, 21 and 22 of the patent were held valid and infringed in an interlocutory decree granted by Judge Patterson. A master was appointed to ascertain and report defendant’s profits, and the latter’s report was confirmed by.the trial court which fixed profits realized by the defendant as reported by the master.

The patent in suit has been before this court on several prior occasions and has uniformly been held valid by us. A. B. Dick v. Simplicator Corporation, 2 Cir., 34 F.2d 935; A. B. Dick V. Shallcross Co., 2 Cir., 42 F.2d 169, and A. B. Dick v. Duplicating Machine & Supply Corp., 2 Cir., 72 F.2d 268. The same result has been reached in the Third and Seventh Circuits. [925]*925Arlac Dry Stencil Corp. v. A. B. Dick, 3 Cir., 46 F.2d 899, and Heyer Duplicator Co. v. A. B. Dick, 7 Cir., 59 F.2d 787. The invention relates to improvements in stencil sheets. As we said in Dick v. Simplicator, 2 Cir., 34 F.2d 935, 936:

“A stencil sheet is a sheet adapted to be converted into a stencil for multiplying copies with less equipment than by printing, particularly in machines which position the paper and stencil and apply ink, so that it passes through the appertures in the stencil and reaches the paper.”

To make such a stencil sheet the patentee says in his specification that he employs “a base of open-texture, porous material of any suitable character, such, * * * as the Japanese bibulous paper commonly known as ‘Yoshino.’ This,” he says, “I coat or impregnate with a cellulose ester, such as cellulose nitrate or cellulose acetate, by treating the paper with a solution of such cellulose ester in a suitable solvent. The material which I prefer to employ and with which excellent results may be obtained is known as ‘pyroxylin enamel,’ this being a solution of nitrated cellulose in a suitable solvent, with which has been incorporated a pigment such as zinc oxide. As commercially available at the present time, this enamel has the consistency, approximately, of ordinary molasses. As is well known, the consistency of pyroxylin enamel is governed by the relation between the solid constituents (such as cellulose nitrate, zinc oxide etc.) and the solvent employed (such as amylacetate).

“To a given quantity of this pyroxylin enamel I add a suitable proportion (fifty per centum will give good results) of a tempering agent such as an oil, mixing this thoroughly with the enamel and, if desired, adding coloring matter such as a dye or carbon black which may have been previously dissolved or suspended in amylace-tate. The chief function of the tempering agent is to prevent the pyroxylin enamel from drying too hard, making the coating undesirably brittle. For this purpose I prefer to use castor oil or a similar oil having the power of forming with the cellulose ester and its solvent a homogeneous body.”

The following claims, 2 and 18, are typical and were found in the interlocutory decree to be infringed by stencil AF:

“2. A stencil-sheet adapted for conversion into a stencil by the impact of type and the like thereon, the same comprising a base having a type-impressible coating including a cellulose compound and a tempering agent.”
“18. A stencil-sheet adapted for conversion into a stencil by the impact of type and the like thereon, the same comprising an open-texture base having a coating including a cellulose ester and a tempering agent.”

In A. B. Dick v. Shallcross Co., 2 Cir., 42 F.2d 169, 170, 171, we gave the claims of the patent in suit a broad construction saying that:

“The patent is limited to no formula, but only teaches that a proper coating for dry stencil sheets should have a small percentage of nitrocellulose and a large percentage of soft materials of an oily character. * * * Hill’s specification does not require that castor oil or any oil shall be used. It says: ‘To a given quantity of this pyroxylin I add a suitable proportion * * * of a tempering agent such as oil. * * * ’ Moreover, even if oil itself were intended as the tempering agent for Hill’s stencil sheets, the test of what is oil is not the chemical meaning of the word but its general meaning, so long as the ingredient used is ‘such as an oil’ and serves the purpose of a tempering agent.”

The defendant sold stencil sheets made by Ellams Duplicator Company of London, England, which are the articles alleged to infringe. While the validity of the patent is not questioned it is argued that the stencil sheets known as types MO 37 and MO do not come within the claims. The stencil sheets before Judge Patterson were known as type AF and were found to contain 3.8 per cent waxy material, 7.1 per cent nitrocellulose, 71.6 per cent liquid oily material and small proportions of other ingredients. This AF type of stencil was held to infringe the claims and such infringement is not and cannot longer be disputed. On the accounting the special mas[926]*926ter allowed proofs to proceed as to other stencils sold by the defendant particularly those known as types MO 37 and MO. The constituents of MO 37 stencils were 75.9 per cent of liquid oily material and 14.7 per cent of nitrocellulose. The constituents of MO stencils were from 61.2 per cent to 76.18 per cent of liquid oily material and from 14.81 per cent to 19.87 nitrocellulose.

It is argued that oil was not used as a tempering agent in any of the stencils alleged to infringe other than type AF. It was not used in the stencil we dealt with in A. B. Dick v. Shallcross Co., 2 Cir., 42 F.2d 169. There the tempering agent was oleic acid and the. stencil was held to infringe. At page 171 we said:

“It softens the pyroxylin so that it will not become hard like enamel after the evaporation of the solvent and has an effect similar to the castor oil recommended both in the patent to Hill and the patent to Shallcross. But Hill’s specification does not require that castor oil or any oil shall be used.”

The plaintiff’s expert Grosvenor testified that the oil liquid found in Exhibit 8, which was stencil type AF, “has substantially the effect on nitrocellulose that oleic acid would have.” (Record p. 14.)

The testimony of the experts Grosvenor and Worden' show that types AF, MO 37 and MO each had a coating which included “a large percentage of oily material and a small percentage of nitro-cellulose distributed through the oily material as a binder therefor” and thus in terms infringed Judge Patterson’s decree.
