Opinion

ROGERS, Circuit Judge.

This is a suit in equity arising under the patent laws of the United States. The plaintiff alleges that he is the sole owner of United States letters patent No. 1,044,944 granted to him on November 19, 1912, for pulley brake for motor-controlled apparatus. He also„alleges that he is the owner of an undivided two-[788]*788thirds interest in United States letters patent No. 984,327, granted on February 14, 1911, to himself and D. Wald and O. C. Britsch for motor-controlled apparatus; the plaintiff’s two-third interest in the said patent being his own undivided one-third interest arising from the grant, together with the interest of his'coinventor, Britsch, which he has acquired by virtue of- an assignment. David Wald, as the owner of the remaining one-third interest, having been requested by plaintiff to join in the suit, and having failed to do so, has been made a defendant. William Forsberg, the other defendant herein, it is alleged, is infringing the plaintiff’s rights under both of these patents. An injunction is sought, together with an accounting of the damages and profits.

The paltents in suit both relate to control and brake apparatus for sewing machines operated by electric motors. Power sewing machines are driven at very high speed, and must be capable of being started and stopped instantly. The treadle used to operate the machine by foot power is utilized to move the speed control lever and apply the brake to the motor when the current is cut off. Counsel called attention to the fact that these machines are not used by skilled mechanics or electricians, and that therefore simplicity of construction and certainty of operation are essential to success. Moreover, it is necessary that the electric control or rheostat should be so constructed as to minimize -or avoid danger of fire, as a spark escaping from the control box might easily set fire to the flimsy dress of the girl operator or the material being sewed. And it is important that the 'apparatus should be very compact, so as to occupy a very small space under the sewing machines. The patents in suit relate to improvements which go to meet the requirements above stated. The claims in suit are of a limited character. In patent No. 984,327 the specification states the object of the invention as follows:

“An object of the invention is to provide simple and efficient apparatus for controlling electric motors, which can be used for various purposes, though particularly useful in connection with motor-driven sewing machines or the like, which is rapid and positive in operation, which can be operated by^ means of a pedal, and which, when the pedal or corresponding part is re-' leased, automatically stops the motor.”

And in patent No. 1,044,944 the specification states the object of the invention as follows:

“An object of my invention is to provide a readily actuated brake mechanism for simultaneously manipulating the brake to apply the same. when the power is shut off, said mechanism having means for adjusting the support of the brake whereby the wear in the latter may be taken up and the effectiveness of the brake action varied.”

If the patents are valid, infringement is admitted. To- defeat the patents, defendant relies upon oral testimony as to prior uses; the testimony being unsupported by any documentary or record evidence. The defendant claims that the inventions of the patents were in public use- more than two years before the patents were granted. A number of patents were set up in the answer, but none of them were referred to by defendant at the trial.

[789]*789The Supreme Court of the United States, in the case of the Barbed Wire Patent, 143 U. S. 275, 12 Sup. Ct. 443, 450, 36 L. Ed. 154 (1892), held that when an unpatented device, the existence and use of which are proven only by oral testimony, is set up as a complete anticipation of a patent, the proof sustaining it must be clear, satisfactory, and beyond a reasonable doubt. The court in the course of its opinion, which was written by Mr. Justice Brown, said:

“We have now to deal with certain unpatented devices, claimed to be complete anticipations of this patent, the existence and use of which are proven only by oral testimony. In view of the unsatisfactory character of such testimony, arising from the forgetfulness of witnesses, their liabiliiy to mistakes, their proneness to recollect things as the party calling them would have them-recollect them, aside from the temptation to actual perjury, courts have not only imposed upon defendants the burden of proving such devices, but have required that the proof shall bo clear, satisfactory, and beyond a reasonable doubt. Witnesses whose memories are prodded by the eagerness of interested parties to elicit testimony favorable to themselves, are not usually to be depended upon for accurate information. The very fact, which courts as well as the public have not failed to recognize, that almost every important patent, from the cotton gin of Whitney to the one under consideration, has been attacked by the testimony of witnesses who imagined they had made similar discoveries long before the patentee had claimed to have invented his device, has tended to throw a certain amount of discredit upon all that class of evidence, and to demand that it be subjected to the closest scrutiny. Indeed, the frequency with which testimony is tortured, or fabricated outright, to build up the defense of a prior use of tbe thing patented, goes far to justify the popular impression that the inventor may be treated as the lawful prey of the infringer. The doctrine was laid down by this court in Coffin v. Ogden, 18 Wall. 120, 124 [21 L. Ed. 821], that ‘the burden of proof rests upon him,’ the defendant, ‘and every reasonable doubt should be resolved against him. If the thing- were embryotic or inchoate, if it rested in speculation or experiment, if the process pursued for its development had failed to reach the point of consummation, it cannot avail to defeat a patent founded upon a discovery or invention which was completed, while in the other case there was only progress, however near that progress may have approximated to the end in view.’ This case was subsequently cited with approval in Cantrell v. Wallick, 117 U. S. 689, 696 [6 Sup. Ct. 970, 29 L. E’d. 1017], and its principle lias been repeatedly acted upon in the different circuits. Hitchcock v. Tremaine, 9 Blatchf. 550 [Fed. Cas. No. 6,540]; Parham v. American Button-Hole Machine Co., 4 Fish. Pat. Cas. 468 [Fed. Cas. No. 10,713]; American Beil Telephone Co. v. People’s Telephone Co. [C. C.) 22 Fed. 309.”

And prior to the decision in the Barbed Wire Patent, Judge Coxe, in Thayer v. Hart (C. C.) 20 Fed. 693, had said:

“The rule in such cases is very strict. It is so easy to fabricate or color evidence of prior invention, and so difficult to contradict it, that proof has been required which does not admit of reasonable doubt.
