91 F. 917 | U.S. Circuit Court for the District of Southern California | 1899
Suit to restrain, and to recover damages on account cf. alleged infringements of a patent (No. 549,875) on an improvement in box machines. Among the defenses to the suit is that of prior public use. It appears from the evidence that several machines, made v. of the same constituent parts, operated upon the same principle, and producing the same results, as the one covered by the patent mentioned in the bill, were used by the Los Angeles Box Company earlier than two years before said patent was applied for. Complainant, however, contends that said use was not a public use. On this point the law, as I understand it, is that where a machine is used for profit, not experiment, and particularly where it is exposed to the view of persons other than the inventor and his employes, pledged or enjoined to secrecy, such use is a public use. Perkins v. Paper Co., 2 Fed. 451; Egbert v. Lippmann, 104 U. S. 333; Henry v. Soapstone Co., 2 Fed. 78; Manufacturing Co. v. Sprague, 123 U. S.
“In considering- the evidence as to the alle'ged prior use for more than two - years of 'an invention, which, if established, will have the effect of invalidating the patent, and where the defense is only met by the allegation that the use was not a public use in the sense of the statute, because it was for the purpose of perfecting an incomplete invention by tests and experiments, the proof on the part of the patentee, .the period covered by the use having been-clearly established, should be full, unequivocal, and convincing.” Manufacturing Co. v. Sprague, supra.
The evidence in the case at bar, so far from being “full, unequivocal, and convincing” in favor of the complainant, is, to my mind, conclusive against him, because it shows that the use in 1887 and 1888 of the. machines in question by the Los Angeles Box Company was not experimental, but for profit, and, furthermore, that during said years the employes who operated said machines were not cautioned as to secrecy; and, besides, the machines were exposed to the view of persons other than complainant and said employes. The Los Angeles Box Company, according to complainant’s own testimony, was during the years 1887 and 1888 a partnership composed of himself and one D. Gager Peck, and manufactured 400,000 boxes in the former year, and 800,000 boxes in the latter year, using about Í0 of said machines, and employing several operatives. Complainant’s testimony as to these matters is as follows; '
“Q. Did you attach the tin strips to .the boxes which you manufactured in 1885 by means of a machine? A. I did. Q. How was this machine constructed? (Objected to for the reasons last-stated.) A. The principle was the same as the machine'we use to-day. *' * * Q. Tn what respects did they differ? A. The pendulum lever was increased in weight. The jaws were changed some. Q. Were there any other- differences? A. Not any that I think worthy of mention. * *. Q. Then, 'if I understand you correctly, the machine shown in your patent of 1895 has been used by you continuously since the year 1887? A. It has. Q. How many employes had you in your business in the year 1889? A, Somewhere from ten to fifteen. Q. How many during the years ’86, ’87, and ’’89? A.- They have-increased some two or three hands a, year. Q. I-Iow many of these machines for securing the tin binding strip upon the boxes did you use. during the year 1885? A. Five or six. Q. How many in ’86? A. Five or six. Q. How. many of the improved machines, like your patent of 1895 did you use in your business'in the year 18S7? A. T think about ten.”
I am satisfied from all the evidence in the case that persons other than complainant, his partner, and their employes had opportunities, to see, and one or more of them did see, said machines while in operation. But, if this were not so, it is certain that complainant’s partner, D. Gager Peck, had free access to said machines; and the law has been declared thus:
“To constitute public use, it is not necessary * * * that more than one person should have known of that use.”. Walk, Pat. § 94, and notes 7 and 8;. Worley v. Tobacco Co., 104 U. S. 340.
Although it may be' different as to employes, the fact that jpeclt was a member of the firm known as the Los Angeles Box Company,.
“The courts very properly limit the meaning of ‘public use’ io a use in the ordinary way, and they may so limit the word ‘sale,’ if they can ever be persuaded of the fact; but, whether use or sale, that particular transaction must be experimental, or it is within the forfeiture of the statute.”
Complainant’s application for his patent was made January 5, 1891; so that the prior use must have been, and, as I have already shown, was, before January 5, 1889.
The improvements, which complainant made in the machine in 1890, namely, increased weight to the pendulum lever, and some changes about the jaws, are not of the substance of the patent, nor did they add anything patentable to the machine; and consequently they do not save the patent from the invalidating effect of the prior public use to which I have adverted. Manufacturing Co. v. Sprague, supra; Machine Co. v. Hargett, 28 Fed. 567; United States Electric Lighting Co. v. Edison Lamp Co., 51 Fed. 24.
Complainant’s objections to the evidence of prior use, on the ground of irrelevancy, are not well taken. The' answer of defendants, in its fourteenth subdivision, pleads expressly complainant’s prior use of the machine at Los Angeles, Cal.
The above rulings render it unnecessary for me to pass upon the other issues raised by the pleadings, and discussed in the briefs of the parties. A decree dismissing the bill will be entered.
