Opinion

TUTTLE, District Judge.

In this suit the plaintiff charges three things against the defendant: Infringement of patent No. 852,450, to Plym, of May 7, 1907; infringement of patent No. 860,150, to Plym, of July 16, 1907; and unfair competition.

[738]*738The defendant admits the validity of the two patents and denies infringement. Defendant also admits that the structures manufactured and sold by it are of such similarity in appearance to plaintiff’s structure that those not technically familiar with the articles would be confused as between the two, and would be likely to take one for the other. Defendant denies, however, that people skilled in the trade and in the art, and those engaged in dealing in and handling the articles would be deceived, and denies that the defendant has ever sold its articles for the articles of the plaintiff, or that it has ever deceived any one with whom they have dealt. I will take these matters up in the order that I have mentioned.

[1] As already stated, the validity of the patent to Plym, No. 852,-450, of May 7, 1907, is admitted; but proof has been offered by the defendant as to the state of the art and prior inventions for the purpose of limiting the scope of the patent, and as bearing upon the question of noninfringement. After hearing all of this proof, and considering all of these matters, the case, on that branch, narrows itself down to the single question as to whether the defendant’s inner gutter is resilient, within the meaning of the patent — whether or not the defendant’s inner gutter actually assists and serves, because of resiliency, in holding the glass. Does it press the glass yieldingly outward, so that, on pressure from the outside, it yields with sufficient resiliency, so that the glass is saved from breaking, and then, when the pressure is withdrawn, the glass is returned to its normal position, and the inner gutter assumes its normal position,- because of resiliency?

Defendant denies that it possesses resiliency, contending that, while on heavy pressure, it will yield, and when the heavy pressure is withdrawn it will resume its normal position, yet denies that the possible forces applied to the glass before the breaking point is reached are such that resiliency of the inner member is brought into play. Results of an experiment were brought to my attention and offered in evidence by the defendant, for the purpose of showing that this inner member is not resilient. This experimental test is not persuasive, as it does not correctly represent the conditions existing in practical use.

In determining this question, of course, the court ought to have in mind the weight of the glass, the amount of pressure that is likely to be exerted against it, the bending qualities of the glass, and all of its different characteristics. Glass, while it can be bent, at the same time possesses great strength, and these large panes of glass are heavy, and must, if they are serviceable and durable, resist heavy strains. The resiliency which the patent intends for the inner member is not that kind of resiliency which is very easily yielding, or it would not serve its purpose. The value of the resilient inner member is to hold the glass in its normal position so much of the time as possible, and to only permit it to leave that normal position on heavy pressure, for the purpose of saving it from being broken.

• I have studied by actual experiment of my own the question of whether or not it was resilient. It yields perceptibly upon pressure. In addition to my own judgment upon that subject, I have had in mind the previous case from this court (Kawneer Manufacturing Company v. Toledo Plate & Window Glass Company [D. C.] 232 Fed. 362), [739]*739in. which the Circuit Court of Appeals of this Circuit (Toledo Plate & Window Glass Co. v. Kawneer Manufacturing Co., 237 Fed. 364) has held a similar inner gutter to be a resilient member. I have not changed my own opinion with reference to the inner gutter of the Toledo Plate Glass Company, which I then thought was resilient. Every thought and every reason which would lead me to think that member resilient would lead me to believe that this one is. Within the proper construction and meaning of the language of the claims of the patent, the inner gutter is resilient.

[2] Defendant’s inner gutter has no turned-down edge or lip which presses flatly against the glass on its - inner surface. On the pressure from the outside I fail to discover any difference in the actual function of defendant’s inner gutter and the same gutter with the flange extending downward and pressing flatly against the glass. I take it any such flange would only offer resistance and add to resiliency on pressure from the inside. On pressure from, the inside it would press against this down-turned edge of the gutter, and the tendency would be to return the glass to its normal position. On pressure from the outside, as soon as the lower or extreme edge of the glass leaves the perpendicular, it would leave such a flange; and I fail to discover any force or any function that would be performed by the flange on the pressure from the outside. While the glass is to be protected and guarded against pressure from both sides, there is a greater occasion or reason for guarding against heavy pressure from the outside; therefore, if there is any difference, it is one of impairment of functions without changing the operation. “Infringement is not avoided by impairment of the functions of an element of a patented device in degree, if the distinguishing feature is retained.” Penfield v. Chambers Bros. Co. (C. C. A. Sixth Circuit) 92 Fed. 630, 653, 34 C. C. A. 579; Murray v. Detroit Wire Spring Co. (C. C. A. Sixth Circuit) 206 Fed. 465, 124 C. C. A. 371, and cases there cited. Defendant’s inner gutter is, in my opinion, resilient, and I hold it to be resilient. I hold claims 5, 6, and 7 of patent No. 852,450 infringed.

[3] Claims 1 and 2 of patent No. 860,150 are the ones in suit and read as follows:

“1. The combination of a channeled front plate, a back plate, a channeled filling strip occupying the channel of the front plate and headed fastening devices extending through the channeled plate and the back plate and having their heads within the channeled filling strip to be covered by the same.
“2. The combination of a channeled front plate provided with lateral flanges, a plate back of the same and provided with resilient wings, a stiffening part engaging the back plate, bolts extending through the channeled front plate, the back plate, and the stiffening part, and a channeled filling strip occupying and closing the channel of the front plate and clamped in position by said bolts." ¥

Defendant, while admitting the validity of this patent, introduced a number of prior patents. The British patent to Shelley, No. 12,036 of 1887, is admitted by defendant’s expert to be the nearest to both plaintiff’s and defendant’s constructions. This does not show a practical construction for store front purposes. This is admitted by defendant’s expert. None of these prior patents show anything which limits either of these claims.

[740]*740The defendant’s structure has a front plate consisting of two glass engaging lateral flanges with inwardly extending members, with a channel between them to receive a channel filling strip. This filling strip is formed as a part of the inwardly extending members of the front plate.
