This is a case in equity for an alleged infringement of several patents of which the Salamander Company is' assignee. The reissued patent, No. 4,134, dated Sept. 27th, 1S70, is reissue of Oct. 5th, 1869, for a composition or cement composed of lime and putty combined as described, with paper pulp or other suitable fibrous nonconducting material, and with the other ingredients named, or their equivalents, etc., and claims the employment of lime putty, when combined with paper pulp or any other suitable fibrous non-conducting substance, as a material for preventing radiation from heated surfaces, or as an ingredient in any composition used for such purposes.
It is alleged that this patent was anticipated by French’s patents, Sept. 14th, 1869, which were for the same purposes, as the foregoing; patent “A” (94,882) was for a composition of crushed asbestos mixed with an alkaline silicate, and “B” (94,883) an improvement on “A” by adding to the mixture a vegetable substance, as “saw-dust and oth*808er woody matter, to make a lighter and cheaper coating.”
The reissue of Johns, No. 5,951 (Div. D), dated June 30, 1874, of original patent, dated April 14, 1868, is of crushed asbestos and lime mixed with water to be applied. The defence, is’ mainly for want of novelty—that the inventions claimed by plaintiffs were anticipated, etc.
Whatever there is in plaintiffs’ patents for which defendant is to be held as an in-fringer, consists in lime putty mixed with non-conducting fibrous material. The subsequent patents on which they rest are for lime putty and crushed asbestos.
It seems from the evidence that plaintiffs are assignees of the French patent, also, but it is not set up in the bill, though mentioned in the amended answer as anticipating the Bissell & Riley, and.also the Riley patents. While some of the Johns patents are set out, che reissue above is not mentioned in the answer.
It seems, from a cursory examination of the case, that if the Johns reissue (not mentioned in the answer, No. 5,951, jf June 30, 1874), relates back to April 14, 1868, the plaintiff’s patents as to asbestos and lime putty were anticipated. So if plaintiff claims all nonconducting fibrous substances mixed with lime putty, the claim is too broad.
If each reissue relates to the date of the original patent, then the Johns patent anticipated those held by plaintiff, and although Johns did not specifically state the use for non-radiation, etc., the plaintiffs can not, because of the new use to which they apply the composition, claim that they were the first and original inventors of the composition. The court, however, can not take notice of what was not set up against plaintiff’s patent.
When this case was before the court previously, it was suggested that if the reissued Johns patent was valid, plaintiff’s patents had been anticipated; and the attention of counsel was also called to the fact that the reissues' to Johns had not been set up. By agreement of counsel those reissues are now before the court, as if made before his suit was brought, and as if fully set up in the defence.
The only additional point, therefore, is as to the validity of the Johns reissue in question, which is for precisely the same compound as that claimed and used by plaintiff. The legal rule is that prima facie a reissue is for the same invention as that originally patented.
Section 4916 of the United States Revised Statutes, copied from the act of 1870 [16 Stat. 198], prescribes for what, and under what circumstances a reissue may be had.
The repeated decisions by the courts, and especially by the United States supreme court, in the 1st, 17th, and 19th Wallace, indicate with sufficient distinctness, that not only no new matter shall be introduced, but that an enlargement of the original claim, growing out of the subsequent advance of the art, is not to be tolerated. The reason of the rule is obvious. Every patent as to novelty or utility depends on the state of the art at the time of the claim made or patent issued, and, therefore, if a party, after learning from a subsequent advance of the art, the worthlessness of his original invention, is to be permitted to claim a reissue incorporating what was not originally in his mind, and what had been afterwards suggested to him only by advances in the art made by others, then he could, it may be, even without any new invention, override all the elements which would serve to test the validity of the new application. In other words, having procured a worthless patent, and having subsequently learned from the advancing art how, by changing the terms of his patent, it could be made of value, he would, if a reissue, including the new matter, were permitted, have the reissue not only relate back to the date of the original patent, but absorb within its privileges all subsequent matters, wholly unknown to, and unthought of by him, originally.
This rule controls both the patent office and the courts. New matter must not be introduced. By new matter is not meant merely the introduction of a new ingredient in a patented composition, but any change in the original specification and claim whereby a new and substantially different composition and results are secured.
Such is the reissue in question. It is not only for a composition essentially different, but for one not within the purpose for which the original invention was designed. The plaintiff is entitled to a decree. Decree for plaintiff.
[Subsequently the following decree was entered of record:
[This cause coming on to be heard upon the pleadings, exhibits, and proofs herein, was argued by counsel, and thereupon, upon consideration thereof, the court doth order, adjudge, and decree that the said several letters patent mentioned and described in the bill of complaint herein are good and valid in law; that the plaintiffs are entitled to the exclusive use and rights under the same; that the said defendant, by the use, manufacture, and sale of the patented improvement described in said letters patent, has infringed upon the exclusive rights of the plaintiffs under the same. It is further ordered, adjudged, and decreed that the said defendant, his agents, clerks, servants, and workmen, and all and every of them, be, and they are hereby, enjoined and restrained from making, selling, using, or in any manner whatsoever disposing of any composition for covering steam-boilers, and for other purposes, embracing the patents or improvements of plaintiffs in their said bill of com*809plaint set forth. It is further ordered, adjudged, and decreed that the defendant pay the costs herein to be taxed, and that execution issue therefor.] 2
