Opinion

Lacombe, J.

This is a suit brought to restrain the defendants from infringing letters patent 348,073, granted to the complainants August 24, 1886, for “an improved reproducing surface for type-writing and manifolding.” The circumstances of the case are peculiar, and present what seems to be a novel question. On March 22, 1886, the complainants filed their application, (known as “Serial Number 196,200.”) The patent issued thereon, and now sued on, sets forth that the invention relates to an improved reproducing surface adapted to be employed for obtaining copies of type-writing, or other printed or written impressions by means of a type-writer or other printing device, or by the employméní of a stylus or other writing means; that the transfer surface is spread upon a sheet or vehicle, and, when so applied, is adapted to be-employed in place of the articles of trade commonly known and designated as “carbon papers,” or “semi-carbon papers.” The specification then proceeds as follows:

“(‘ Carbon papers,’ or • semi-carbon papers ’) are employed by,type-writers and others to produce copies of impressions either obtained by a machine or by a stylus or other writing means. In carrying out our invention, we em[683] ploy in the manufacturo of our improved transfer surface dye-wood solutions, or their active principles, which we filter and precipitate witli alkalies and mineral salts, or with alkalies, acids, and mineral salts, or with acids or alkalies alone. After the solution has been filtered, the precipitate is removed from the filtering device, and dried. The precipitate is then mixed witli lard-oil and wax, or their equivalents, and the mixture is then ground together in a warm state. The dye solutions we prefer to employ are obtained from log-wood or lunmatoxylin, the active principle of logwood, Brazil wood, sapan wood, peach-wood, madder, or its active principle,— alizarine. The proportions we find to answer well in producing our improved surface are as follows: Take one pound of extract of logwood and dissolve the same in one gallon of water. Then add to the solution one pound of soda and one pound of mineral salt, using one of the salts of iron or copper, preferably sulphate of copper. The mixture thus obtained is then placed in a filter. After the solution has been filtered, the precipitate is removed from the device employed for filtering, and then dried, after which the precipitate is ready for use. To every two pounds of precipitate thus obtained we add one pound of oil and one pound of wax, and then grind the mixture, in a warm state, in what is commonly known as a ‘ paint ’ or other suitable grinding mill. The heated mixture thus obtained is then applied to tissue paper or other suitable paper or fabric by means of a sponge or other suitable transferring device. The paper or fabric to which our improved surface is to be applied is placed upon a heated table, by preference formed of iron, and heated by steam; but this may be varied. In place of employing oil or wax, or both combined, we can employ any other suitable oleaginous matter or combination of oleaginous matter having equivalent or approximately equivalent properties.”

The invention having been thus described, the patentees claimed “a sheet of material or fabric coated with a composition composed of a precipitate of dye-matter, obtained as described, in combination with oil, wax, or oleaginous matter, substantially as and for the purposes set forth.” On the same day (March 22, 1886, serial number 196, 199) complainants also applied for a patent for a “composition for transfer surfaces for producing copies of type-writing,” and letters patent therefor (No. 348,072) were issued to complainants on the same day as those sued on, —August 24, 1886. The specification sets forth that the invention relates to the process of producing a transfer surface adapted to bo. employed upon a sheet or vehicle to take the place oí' the articles of trade commonly known and designated as “carbon papers” or “senn-ourcon papers.” It then stales that-these papers are employed by type-writers or others to produce copies of impressions either obtained by a machine, or by a stylus or other writing means, and proceeds to describe the invention in the identical words used in the other patent, and quoted above. Having thus described their invention, the patentees claimed :

“Tlie coloring composition herein described for the manufacture of a substitute for carbon paper, composed of a precipitate of dye-matter, in combination witli oil, wax, or oleaginous matter, substantially'as set forth.”

This novel method of manifolding an.invention was adopted, as.complainants state, in order to comply with recent decisions of the patent-office, interpreting rule 41 of that office, and holding that where'a-person has “invented something- in an art, or, as it is ordinarily called,:.‘a. process,’ also a machine for carrying out the process, and also the-mail[684] ufacture or article which is produced in the operation or the process by the machine,” he must take out three separate patents,—one for the process, one for the machine, and one for the product. Ex parte Blythe, 30 O.G. 1321; Ex parte Herr, 41 O. G. 463. Before those decisions the patent would have contained the common specification above quoted wdth two separate claims,—one for the process'and resulting composition; the other for its combination with the paper. The complainants insist that their position is precisely the same whether their invention is covered by a single patent with a double claim, or by two separate patents. Whether this is so, under the circumstances of the particular case here presented, must be now determined.
