Opinion

FAKE, Chief Judge.

This is a declaratory judgment proceeding in which the plaintiff seeks to have a certain patent, now owned by defendant, Specialties Development Corporation, declared invalid. The patent is known as Minor Patent No. 1,760,274. Plaintiff also charges both defendants with unfair competition.

Defendants have counterclaimed, charging infringement of the Minor patent, and also infringement of Towart Reissue patent No. 22,045, and Mapes Reissue patent No. 18,839, and Grant Design patent No. 121,-011. Plaintiff, answering the counterclaim, alleges invalidity of each of the four patents and denies infringement of the claims thereof

In re the Minor Patent 1,760,274.

This patent was applied for September 26, 1925, and issued on May 27, 1930. It relates to carbon dioxide fire extinguishers. There are three claims in the patent, of which Claim 3. furnishes an example. It reads as follows: “In a fire extinguishing apparatus employing liquid carbon dioxide discharged without entrainment of air, the combination -comprising a container of liquid carbon dioxide, a nozzle having a restricted discharge orifice and in free communication with said con-[317]*317tamer so that liquid carbon dioxide only is delivered to the mouth of the nozzle and discharged therefrom, and an outwardly flaring shield of substantial length, which shield completely encloses at its smaller end the nozzle and surrounds the discharge from the nozzle.”

The gist of this patent, when read with the specification and the other two claims, seems to reside in the use of a flaring cone shaped shield, or a flaring rectangular shield in connection with a discharge nozzle from which liquid carbon dioxide is ejected, under pressure, into the flaring shield. Its virtue is said to reside in the fact that the shield flaring outwardly, and made in proportion as shown in the drawings, results in a discharge of the carbon dioxide without the entrainment of air or without any substantial entrainment thereof. Thus quenching fire, in part at least, by creating an absence of sufficient oxygen upon which the fire might feed. I am convinced that this combination of, elements has resulted in a better and more efficient portable fire extinguisher than any of those wherein any other method has been involved. Its virtues are attested to by public acceptance; a demonstration before the Court in a moving picture, and the financial success of those who have put it on the market. However, the vital issue here is involved in the question as to who first invented it or gave the complete idea of it to the public. In this connection it appears that Dr. Jones, who was an expert witness in this case, and a Fellow of the Mellon Institute, back in May of ' 1924, published an article in the Electrical World, on a dry CO2 gas fire extinguisher, in which is shown a flaring cone shaped shield in connection with a nozzle for the use of carbon dioxide. While this article is headed “Dry CO2 Gas” the author says, in paragraph I (Exhibit P-S) : That there is placed in the cylinder “a siphon tube which delivers the carbon dioxide as -a liquid through a flexible metal hose.” Insofar as the flaring conical shield is concerned it reads directly on the patent in suit. Nothing is said, however, to explain the virtue of the flaring cone, except to say that the use of such a cone was made public in prior experiments with fire extinguishing units by the Bell Telephone Co. of Pennsylvania prior to the year 1924. Notwithstanding that the writer after stating that because of certain defects, found by the Bell Telephone Company, among them lack of dependability because of “ * * * the tendency of the value (sic valve) used to freeze up, this type of extinguisher was never adopted generally * * The writer then says, “The freezing up formerly experienced was due to the vaporization of liquefied carbon dioxide in the cylinder. This cooling effect is now made available for ‘freezing’ the fire by placing in the cylinder a siphon tube which delivers the carbon dioxide as a liquid through a flexible metal hose * * Later, on March 31, 1925, some five months before Minor, Dr. Jones filed an application for the Jones Patent No. 1,644,338. This patent issued on October 4, 19.27 about three years before Minor. Looking now to this Jones patent, it is found that it follows partly the teaching of Jones’ prior publication. Any question bearing on differences between Jones and Minor, bearing on dry, as distinguished from liquefied carbon dioxide, is cleared up, since in explaining Jones’ patent he says, “This invention relates to discharging carbon dioxide and is shown as being particularly applied to a fire extinguisher employing liquefied carbon dioxide.” The drawings accompanying this patent bear striking resemblance to the drawings shown in the later Minor patent, and the method of operation is also substantially the same. However Minor stresses the fact that his patent covers the use of an outward flaring shield of such length “that the discharge when issuing from the shield no longer has sufficient velocity to entrain substantially any air.” It seems to me that this is but to explain, with equal force, why Jones’ prior flaring shield was efficient. So far as Jones is concerned it was quite immaterial that he did not stress the subject of the entrainment of air. His teaching discloses a device that actually did reduce the entrainment of air. Jones’ explanation as to why he did not claim the shield in his patent is convincing. His thought was that the Bell Telephone experiments had taught its [318]*318use publicly at a prior period. Moreover, the close relationship between Jones and Minor, and the correspondence between them, lead to the conviction that Jones was prior to Minor in the inventive thought involved in the flaring shield, and that Bell Telephone preceded them both. I, therefore, conclude that the Jones Article, the Jones Patent, and the Bell prior use, requires a finding that the Minor patent is invalid. It is not necessary, therefore, to deal with any of the issues involving its infringement.

In re the Towart Patent, Reissue , Patent No. 22,045

Defendants charge that plaintiff infringes this patent. Plaintiff asserts its invalidity and non-infringement. Towart says, of this patent: It relates to “high pressure fluid medium containers and control valves therefor equipped with an easily . manipulated finger-operated control adapted for use with fire extinguishers and other high pressure fluid medium applications.”

A study of the claims of this patent, together with the drawings and specification, indicate that several elements or factors are involved in its operation, and that the core or gist of it is found in what is termed “a wholly unattached compressible discharge passage closure disc” adapted to seat and remain seated mainly by action of pressure in the valve chamber. This so called disc may float freely within its confines. It is supposed to move to and close an opening to the atmosphere upon application of pressure from a supply tank, thus sealing the contents of the supply tank. Forward of this disc, when thus seated, is a pin or rod moved by a hand trigger, and when so moved the disc leaves its seat and the contents of the tank is ejected. It is taught by this patent that when the rod or pin is withdrawn from contact with the disc, the disc will return to its seat by pressure from the tank. This I am quite unable to agree with. The testimony of the witness Yeomans convinces me on this subject that if would not.
