Opinion

SPARKS, Circuit Judge.

Appellees charged appellant with infringement of Lander Patent No. 1,429,288, and Benedict and dose Reissue Patent No. 18,188. The first patent was issued September 19, 1922, on an application filed February 19, 1920. The second was issued September 15, 1931, on an application filed September 17, 1927. This patent was a reissue of original patent No. 1,603,506, which in turn was issued on October 19, 1926, on an application filed April 8, 1920. The defenses were invalidity, non-infringement, and laches in applying for the reissue patent. The District Court decreed that both patents were valid and infringed, and from that ruling this appeal is prosecuted.

Lander Patent No. 1,429,288.

Claim 1 of this patent was relied upon.1 It relates to the art of treating wood and other porous material, and comprises alleged improvements over the applicant’s other prior patents. The substances which are susceptible to treatment by the disclosures of (his patent are such as are characterized by interstitial structures, capable of taking up a liquid by capillary absorption.

The principal object of the invention is to render porous bodies impervious to water by reason of the increased inner structural continuity imparted to such bodies by the disclosed process of impregnation. A further object is to regulate the quantity of impregnating material distributed uniformly or otherwise within the body.

The impregnating composition preferably employed comprises crude petrolatum' and resin dissolved in a carrier of gasoline, or the like. When using crude petrolatum and common resin in gasoline, the latter serves as a volatile carrier which conveys the petrolatum and resin into the material to be impregnated, after which the gasoline is evaporated. By decreasing the percentage of resin and increasing the percentage of petrolatum, a composition for rendering the treated materials more pliable and soft is obtained. By varying the proportions of the volatile carrier and the impregnating material, it is possible to control the relative density and the amount of impregnating material distributed within the pores of the body. The distribution is made uniform by completely saturating the body, because saturation is obtained when an amount of liquid is absorbed that completely fills the pores irrespective of its constituency. If the volatile matter forms a relatively large proportion of the absorbed liquid, a small amount of the impregnating material remains, hence the proportion of volatile matter used determines the amount of material deposited.

It must be borne in mind that the claim here relied on is for a method or process. Other patents of appellees cover the product and the devices for producing the same. All of the claims of this patent deal with a process of waterproofing porous materials generally, and there is no specific mention of the use of such materials for expansion joints. There are four claims to this patent. The last three stress the gradual dipping of the lower end of the [324]*324material into the fluid, and gradually increasing the depth of immersion of the material in the medium as impregnation progresses towards the upper end of the material. The specification refers to this method of immersion as a cardinal feature of the disclosure. Claim 1, however, makes no mention of this gradual dipping method, and we are not disposed to read it into the claim. If we should do so, it is obvious that appellant’s method would not infringe .claim 1, because it does not employ that form of immersion.

Literally construed, claim 1 purports to teach a method of regulating the amount of the impregnating component deposited in the porous material, and regulating the proportion of the impregnating component to gasoline, and completely saturating the porous material in the bath. It says: “If the volatile matter (gasoline) forms a relatively large proportion of this absorbed liquid, -evidently a small amount of the impregnating material remains; regulation of the proportion of volatile matter to impregnating material then controls the amount of the material deposited.”

In carrying out the teaching of this claim, the operator first determines the quantity of the elements in his impregnating composition. The specification suggests 20 per cent resin, 20 per cent petrolatum and 60 per cent gasoline by weight, and states that these proportions have been found to be very satisfactory. However, the patentee does not limit himself to the quantities .suggested, for all may vary ac-r cording to -the character of the articles to be treated. In each case the quantities of the elements are to be determined by the judgment of the operator. After the impregnating solution has been prepared; the fibrous material is saturated with it, and after the volatile carrier has evaporated there is a distribution of the resin and petrolatum throughout the pores of the fibrous body in the same proportion as contained in the original solution. This does not mean that the pores are full after the evaporation. Indeed, they could not be, for whatever' space was occupied by the gasoline is still vacant after the evaporation. All that this claim discloses in this respect is that after the evaporation there is an even distribution throughout the pores of the fibrous material of the combined resin and petrolatum, providing of course there has been a perfect solution of the impregnating elements. This does not mean that all of the bath solution has impregnated a given number of' fibrous boards, or a given amount of fibrous material. It means that each item of fibrous material thus immersed has been impregnated with a solution of the particular constituency as predetermined by the operator. For instance, if the operator desires to make a bath containing 100 pounds of resin, as suggested in the specification, he would likewise use 100 pounds of petrolatum and he would use 300 pounds of gasoline.

After the gasoline has dissolved the other two elements, the solution is ready for the immersion of the fibrous element, and by that immersion and the saturation of the fibrous material, Lander claimed to have discovered a new method by which the wood fiber would be impregnated with resin and petrolatum in the precise degree which he had contemplated. As stated above, he did not limit the claim as to the particular quantities of the elements comprising the bath. He further stated that he had discovered that if one desired a stronger solution of resin and petrolatum, less gasoline should be used, and if one desired a weaker solution of those elements, he should use more gasoline.

We are unable to see any novelty in this disclosure. Certainly there was no discovery in suddenly realizing that a solution of a substance and a solvent might be made thicker or thinner by tlie use of more of the substance or less of the solvent. Surely, it was no discovery to realize for the first time that the saturation of a porous substance in a perfect solution of elements would distribute that solution evenly throughout the pores. Aside from the prior art, these facts have been known from time immemorial and we cannot believe that the patent laws of this country were ever intended to protect a monopoly of their use. The District Court found that the prior art furnished instances of regulating a proportion of impregnating compound and carrier, but it was of the opinion that the prior art did not disclose a precise regulation of the impregnation elements by complete^ saturating the material to be impregnated. We think all of these things were taught by Carmichael, No. 377,928, and clearly suggested by Moore and Rogers, No.
