109 F. 652 | 9th Cir. | 1901
Herman Cramer, the defendant in error, brought an action at law against the Singer Manufacturing Company, the plaintiff in error, for an infringement of the first claim of letters patent Ho. 271,426, of date January 30, 1883, for a new and improved sewing-machine treadle. The machines which were manufactured by the Singer Manufacturing Company, and which it was alleged infringed upon the Cramer patent, were made under letters patent Ho. 306,469, issued October 14, 1884, to Phillip Diehl, for “sewing-machine stand and treadle.” Claim 1 of the Cramer patent reads as follows:
“The vertical double brace joining the legs of the two ends of a sewing machine, provided with holes through its lower extremities to serve as hearings, in combination with a treadle provided with trunnions fitted to oscillate in said hearings, substantially as specified.”
The specification described the treadle as provided with two trunnions cast as a solid portion thereof, and extending from its sides into loopholes in the vertical double brace, the trunnions being sharpened to an edge or corner along their lower sides, and the lower end of the loopholes being hollowed to an angle more obtuse than the edge of the trunnion, to serve as bearings for the same, and to permit the rocking motion common to treadles. The inventor proceeded to say: “I am aware that sewing-machine treadles have before been provided with Y-shaped hearings, and I do not claim the same as my invention.” The case was tried before a jury, who found for the defendant in error, and assessed his damages at $12,456. Much of the discussion which is found in the voluminous briefs for the plaintiff in error pertains more properly to the merits of the controversy, the construction of the patent, and the weight of the evidence which was introduced before the jury, and would he more directly applicable to the case if this were an equity suit, and were here on appeal. It must he borne in mind that the case comes to us by writ of error to review a judgment rendered upon the verdict of a jury, which can he reviewed only according to the principles of the common law and in the particulars to which error is assigned. Our attention must not be diverted from the questions whether the trial court erred in its rulings upon the evidence, or in giving or refusing instructions to the jury, or in refusing to take the case from the jury upon the ground which was stated in the motion therefor.
One of the assignments of error principally relied on by the plaintiff in error is that the court refused to give a peremptory instruction to the jury at the close of the evidence to find for the defendant. This instruction was asked upon the ground that “no infringement had been shown.” Whether or not it was error to refuse the instruction depends upon whether there was any evidence whatever of infringement, which, if credited by the jury, would have
But it is contended that, inasmuch as the claim of the Cramer patent is- for a combination of elements, all of which were old, the patent is not entitled to the doctrine of equivalents, but must be confined to the form which is presented in the claim and specifications. It is urged that the Diehl patent presents material variations from those forms, — so material as to avoid the charge of infringement. It
It is earnestly contended that, inasmuch as the claim of the Cramer patent calls for a “treadle provided with trunnions,” the trunnions are made an essential feature of the construction of the treadle, and (hat there can he no iníringément by the use of a treadle which has no trunnions. We do not think, however, that the court should iiave taken the case from the jury upon that ground. In order I o mount the Cramer treadle in the vertical cross brace upon knife-edged hearings, it was absolutely necessary that it be provided with trunnions or Hie equivalent thereof. The trunnions in this case are the knife edges of the hearings, no more and no less. There could he no such hearings without the projections, by whatever name they may be called. If the patentee was entitled to the doctrine of mechanical-equivalents, and to the protection of the right to mount his treadle in the vertical cross brace with bearings, whether knife-edged or point-center, his right certainly is not affected or diminished by the use of the words “provided with trunnions,” as found in Id's claim, provided that the jury found, as they may have done from the evidence, that the one element of Ms combination, which consisted in mounting the treadle in the cross brace, was new, and that the hearings used in the Diehl patent were the mechanical equivalent of Ms hearings.
It is contended that the court erred in excluding certain evidence which was offered concerning the alleged complicity of the Singer Oompany with a prior action prosecuted by the defendant in error against an agent of the company. That action had been brought in
The point is made that in his original application for a patent, filed in May, 1882, the defendant in error designated his invention a mechanism to form a “noiseless, self-adjusting treadle,” and that he made no allusion to the feature thereof which is now deemed of prime importance, until his specification was subsequently so amended by his attorneys as to contain the declaration that his invention had for one of its objects to provide means “to keep the treadle bearings rigidlv in line and at a fixed distance apart, to avoid friction.”
Error is assigned to the refusal of the court to charge the jury that a witness false in one particular of his testimony is to be distrusted in others. It is contended that that instruction was properly applicable to certain testimony of. the defendant in error. It was shown that upon the trial of the former action of Cramer against Pry, in 1895, the defendant in error did not carry his invention back of the year 1882, whereas in the present case he places the date thereof as early as 1880, and it was argued that the testimony in the present case must therefore be false. It was said, also, that the testimony of the witnesses of the plaintiff in error concerning the date at which machines containing the Diehl patent were offered for sale conclusively impeached the testimony of the defendant in error upon the same subject. The rule is that the jury may reject the whole of the testimony of a witness who has willfully sworn falsely as to a material point. In People v. Strong, 30 Cal. 155, it was said that the rule did not apply to mistakes which were the result of error, inaccuracy, or embarrassment, without any real intention to misrepresent or deceive. The vice of the charge as requested is that it left out the two essential elements, that the false testimony must have been willfully false, and must have referred to material matter. There was no error, therefore, in denying it. People v. Sprague, 53 Cal. 494; People v. Soto, 59 Cal. 369; People v. Plyler, 121 Cal. 163, 53 Pac. 553.
Several of the assignments of error are directed to the instructions given by the couit to the jury upon the subject of damages.
“The evidence as to the amount of damages claimed by plaintiff is not very satisfactory, but it may be that the actual sales made by the defendant, in this district, of sewing machines containing the alleged infringing device, for the period named, could not have been ascertained without great labor and delay, and, as a practical way of presenting this evidence, the plaintiff has done all that could be reasonably expected under the circumstances.”
That which defendant did to show the extent of the infringement was to call upon the plaintiff in error to disclose the number of machines it had sold within the district under the Diehl patent. For this purpose the agent of the Singer Company was called as a witness. It was then agreed between the parties that, in view of the difficulty of ascertaining the exact number of such machines sold, the agent might estimate the same. He estimated the number at 12,456. The jury, in assessing the damages, apparently allowed $1 for each machine sold. We do not see that the instruction above quoted, or any of the instructions given by the court concerning the question of damages, was erroneous, or that the court erred in refusing to give instructions asked for by the plaintiff in error. The defendant in error had a monopoly of his own invention. He had not sold the right to any other to manufacture or to vend the same. He had fixed a price of $5 extra for each machine containing his treadle, or a net royalty of $3.50. He testified that he was able and ready to supply the demand for his improvement, and that his market was destroyed by the action of the plaintiff in error.
Concerning the damages sustained by a patentee from infringement, Walker, in his work on Patents (section 563), says:
“If he maintains a close monopoly, and Is ready and able to furnish the whole market with the patented articles, he must prove by satisfactory evidence the advantages gained by the infringer in the unlawful use of the patent, over and above the advantages which he could have derived from the use of similar articles unpatented and open to the use of the public, or must prove the loss or falling off of his own sales in consequence of the infringement, or a loss by the compulsory reduction of prices made, necessary by the competition of the Infringer. The rule varies witli the special circumstances of the particular case [citing Seymour v. McCormick, 16 How. 480, 14 L. Ed. 1024; Philp v. Nock, 17 Wall. 460, 21 L. Ed. 679; and Birdsall v. Coolidge, 93 U. S. 64, 23 L. Ed. 802].”
The plaintiff in error contends, further, that there is no evidence to sustain a verdict for more than nominal damages, and that the record shows affirmatively that the defendant in error sustained no injury by reason of the acts of the plaintiff in error; that by his
There are numerous additional assignments of error, which we have carefully considered, but do not deem it necessary to discuss, further than to say that in none of them do we find error for which the judgment should be reversed. The judgment will therefore be affirmed.
