(after stating the facts as above).
Infringement upon the patentee’s rights is a tort; it is a taking of the patentee’s property. The measure of damages for that wrong is sometimes clear and sometimes its borders are obscure. We may with benefit compare the rules of damages as applied to property generally; for patents have no peculiarities making general rules of law wholly inapplicable. When we are asked to determine how much compensation an owner of any property should have because it has been wrongfully taken, our first thought is of the market value. The market value of the property or the impairment of that value is the ordinary, normal measure of damages. Obviously, where the act done is the wrongful manufacture and sale of a patented article, the thing taken is the right to manufacture and sell. This is the right which would be given by a license fronr the patentee, and, since the recovery and collection of full damages (past and future) for a sale operates to give a license to the vendee (Stutz v. Armstrong [C. C.]
With reference to the owner’s exclusive right under some patents, just as with reference to innumerable other items or whole classes of property, it often happens that there is no market value. In such case, the law always looks for some other appropriate measure. This is perhaps most commonly found, with reference to general property, in
Returning, now, to the observation of all other kinds of property and rights excepting patent rights, there remains a class of cases or a group of instances where no market value existed and where no loss or impairment of sales can be definitely proved. The law is not, in such case, impotent. Plaintiff is not compelled to go away with nominal damages just because he cannot show that his property, or other like it, was commonly bought and sold on the market, or because he did not wish to sell, or because it was returning him no income. The real'value — the actual value — of what has been taken is always the ultimate question. Proof of market value is one way to show this actual loss; proof of lost sales is another way. But, if neither of these methods can be followed, the law permits other available, pertinent proofs. Those familiar with real estate estimate and testify to the real value or fair value of land which is without market value (Chicago, etc., Ry. v. Ohio Co. [C. C. A. 6]
Further pertinent familiar illustration is found in the settled rules concerning the estimation of values of property taken in the exercise of the right of eminent domain. It frequently happens that property is taken which is so situated and environed as not to possess any market value; and yet its value is universally solved by opinion evidence. Constitutional inhibitions against taking private property without compensation are no more restrictive upon the government or the agency exercising the power than are other organic provisions which were aimed against mere wrongdoers who appropriate rights of property like those involved under patent grants. It is a travesty to allow property rights to be seized, and enjoyed without remedy simply be
Save for the effect of the decided cases, we should have no hesitation in affirming the right of the patentee to recover such “general damage” or “reasonable royalty” in a case where the clearer criteria did not exist, where the utility and advantages of the invention were established and where there was substantial basis for estimating the value of these advantages.
“But this only enhances the obligation, of the courts to find a way, if it be possible, to redress the wrongs done by those who have been willing to gather the fruit into their own basket.”
What are the decisions? In Seymour v. McCormick,
It appeared that Hayden had a patent upon improvements in machines for cleaning cotton, that the Suffolk Company had infringed and that no sales or licenses had been granted; but the court below permitted an expert to describe the use and advantages of the invention as compared with the previous methods, and the plaintiff also proved the amount of cotton that* had been cleaned by the infringing machines. The court charged the jury that the plaintiff was entitled to the actual damages sustained from the infringement, and said:
“You will look at tbe value of the thing used, and ascertain that value by all the evidence as to its character operation, and effect. You will take into view the value of that which the defendants have used belonging to the plaintiff.”
This charge was assigned as error. The opinion of the Supreme Court was by Mr. Justice Nelson. The assignment of error was overruled, and the court said:
“This question of damages, under the rule given in the statute, is always attended with difficulty and embarrassment both to the court and jury. There being no established patent or license fee in the case, in order to get at a fair measure of damages, or even an approximation to it, general evidence must necessarily be resorted to. And what evidence could be more appropriate and pertinent than that of the utility and advantage of the invention over the old modes or devices that had been used for working out similar results? With a knowledge of these benefits to the persons who have used the invention, and the extent of the use by the infringer, a jury will be in possession of material and controlling facts that may enable them, in the exercise of a sound judgment, to ascertain the damages, or, in other words, the loss to the patentee or owner, by the piracy, instead of the purchase of the use of the invention.”
The principle of Suffolk v. Hayden was frequently applied by the Supreme Court. In Philp v. Nock, 84 U S. (17 Wall.) 460, 462 (
“The measure of damages to be recovered against infringers prescribed by the act of 1836 as well as by the act of 1870, is ‘the actual damages sustained by the plaintiff.’ Where the ifiaintiff has sought his profit in the form of a royalty paid by his licensees, and there are no peculiar circumstances in the case, the amount to be recovered will be regulated by that standard. If that*619 test cannot be applied, he will be entitled to an amount which will compensate him for the injury to which he has been subjected by the piracy. In arriving- at their conclusion, the profit made by the defendant and that lost by the plaintiff are among the elements which the jury may consider.”
In Burdell v. Denig,
“No doubt, in the absence of satisfactory evidence of either class in the form to which it is most appropriate, the other may be resorted to as one of the elements from which the damages or the compensation may be ascertained.”
Birdsall v. Coolidge,
“Still, it is obvious that there cannot be any one rule of damages prescribed which will apply in all cases, even where it is conceded that the finding must be limited to actual damages. Frequent cases arise where proof of an established royalty furnishes a pretty safe guide both for the instructions of the court and the finding of the jury. Reported cases of undoubted authority- may be referred to which support that proposition; and yet it is believed to be good law, that the rule cannot be applied without qualification, where the patented improvement has been used only to a limited extent and for a short time, but that in such a case the jury should find less than the amount of the license fee; and it is admitted in several cases that the circumstances may be such that the finding should be larger than the royalty.”
In Root v. Railway Co.,
“Where there is no established patent or license foe in the case, or even an approximation to it, general evidence must necessarily he resorted to. * * *
“And what evidence * * * could be more appropriate and pertinent than that of the utility and advantages of the invention?”
The principle was again distinctly recognized by Mr. Justice Brown, when he said, in Sessions v. Romadka,
“This court has, however, repeatedly held that, in estimating damages in the absence of a royalty, it is proper to consider the savings of the defendant in the use of the patented device;”
although this comment loses some of its force, because the case before the court was an accounting for profits.
In the lower federal courts, also, the principle of Suffolk v. Hayden has been repeatedly applied. In Judson v. Bradford, Fed. Cas. No. 7,564, what evidence was given affecting the amount of damages does not appear from the report. Mr. Justice Clifford said:
“Frequent cases arise where proof of an established royalty furnishes a pretty safe guide for the instructions of the court and the finding of the jury, but cases also arise where it cannot be applied without qualification, as where a patented improvement has been used only to a limited extent and for a very short period. Proof of a single license was given in this case, but it cannot, in view of the circumstances, be regarded as affording the only measure ot*620 compensation to which the plaintiff is entitled. Where there is proof of an established license fee, it may, in á case of protracted infringement, be regarded as a pretty safe guide; but the proof in this case is not of that character, and, in such a case, general evidence may be resorted to as the basis of decision.
“Neither party having furnished any definite evidence as to the amount of the injury sustained by the plaintiff, the court is compelled to estimate the same from evidence introduced upon the subject. Weighed in review of the whole evidence, as the question must be, the court finds that the plaintiff! is entitled to recover, as compensation for .the injury occasioned by the infringement, the sum of $300. * * * ”
In Westcott v. Rude (C. C.)
In Wooster v. Thornton (C. C.)
“It is understood that an established royalty or license fee is evidence, and not an absolute test, of value. Whether the situation was such that the value was equal to the license fee before the latter became established was a question of fact for the master. The weight of the evidence was for him. The court cannot say, as matter of law, that the license fee, which did not become established until afterwards, should govern.”
In Graham v. Plano Co. (C. C.)
In Ross v. Montana Co. (C. C.)
“You are instructed upon the question of the measure of the damages that in this case the proper method of assessing plaintiff’s damages, if you find that he is entitled to recover any, is for you to ascertain and determine what would have been a reasonable royalty for the defendant to have paid for the use of the cars in question at so much per car.”
In Lee v. Pillsbury (C. C.)
“If * * * [plaintiff’s] rights have been invaded under this patent by the defendants, then he is entitled to actual damages, and the question then presented is, What amount is he entitled to recover V You can readily see, where there is no license fee, no price fixed for the royalty, and nothing disclosed which would show that the patentee puts on the market a machine, for the use of which he charges so much, it is a very difficult matter to determine*621 what the amount of damages may be in a certain case; but, like all questions presented to a jury for their determination, the plaintiff is bound and required to give some data, and must furnish the jury with evidence, so that they may be enabled to come to a proximate amount of the damage which the patentee has sustained by the infringement. In other words, general evidence may be resorted to for the purpose of furnishing data for the jury to come to a conclusion. * * * Upon those data you are furnished with something by which you can arrive at perhaps not an accurate, but an approximate conclusion as to what amount of damage has been suffered by the plaintiff.”
In Brickill v. Mayor,
“If you find in favor of the plaintiffs, you should consider the utility and advantage to the defendant of the use of the patented device, as compared to any other means of obtaining similar results which were open to the defendant to use, and you may consider the cost of using one as compared with the cost and savings to the defendant of using the other; and from these data, if proven to you, you should ascertain, in the exercise of a sound judgment, what would be a fair compensation to the plaintiffs for the damage which they have sustained by reason of the defendant having infringed, instead of having purchased the right to use the invention.”
It will be noticed that the defendant’s savings or profits were not to be taken as the measure of plaintiff’s damages, but only as a part of the data from which fair compensation to plaintiff was to be determined. The Circuit Court of Appeals of the Fourth Circuit said:
“The rule now well established relative to the question of damages in casos of this kind was properly given by the court to the jury.”
The case is no less authority upon the proposition it announces because the jury, under this instruction, had found only nominal damages.
In Hunt v. Cassiday,
“The plaintiff was clearly entitled to damages for the infringement. If there had been an established royalty, the jury could have taken that sum as the measure of damages. Tn the absence of such royalty, and in the absence of proof of lost sales or injury by competition, tbe only measure of damages was such sum as, under all the circumstances, would have been a reasonable royalty for the defendant to have paid. This amount it was the province of the jury to determine. In so doing, they did not make a contract for the parties, but found a measure of damages.”
Recognizing this as the established rule, Mr. Walker, in his third edition Q.895, § 563, p. 432), said;
“Where damages cannot be assessed on the basis of a royalty nor on that of lost sales nor on that of reduced profits, the proper method of assessing them is to ascertain what would have been a reasonable royalty Cor the in-fringer to have paid. In determining this point where the infringement consisted of making and selling, or in selling after a purchase, the profits of the defendant may be considered; and where the infringment consisted in using,*622 tile cost and the utility of the patented process or thing as compared with the Other process or things Known at the time of the infringement and capable of doing similar work may be the leading guides. But those profits and advantages do not alone show what a reasonable royalty would have been, because it would not be reasonable for a royalty to be as much as the entire benefit derived from the business by a licensee. Therefore an instruction to the jury that the plaintiff was entitled to recover whatever value the defendant had received from the use of the plaintiff’s invention was an error.”
In Robinson on Patents, § 1061; Note 1, and in the course of an introduction to an exhaustive and careful analysis of the cases on damages and profits, the learned author says:
“Profits were, until recently, the only measure of damages in equity. They have always been admissible in evidence upon the question of the amount of damages at law.”
The principle thus established by Suffolk v. Hayden, arid generally recognized by the courts and text-books, has been more recently affirmed and applied by the Circuit Court of Appeals for the Third Circuit. In McCune v. B. & O. Ry. Co.,
In Bemis Co. v. Brill Co.,
The right of a plaintiff to recover in a suitable case this “reasonable royalty” would probably be unquestioned, except for the decision of the Supreme Court in Coupe v. Royer,
“Upon this state of facts, the evidence disclosing tile existence of no license fee, no impairment of the plaintiffs’ market, in short, no damages of any kind, we think the court should have instructed the jury, if they found for the plaintiffs at all, to And nominal damages only.”
This cannot be rej ected as mere dictum; it was said by way of indicating the practice to be observed upon a new trial, and so it must be considered as the ruling of the court; but its comparatively casual character warns us against giving it unintended effect. Indeed, the language of this sentence seems to have been carefully chosen so that it should not go beyond the instant case. Its conclusion is predicated not only upon the lack of evidence of an existing license fee or of an impairment of plaintiff’s market, but also upon the lack of evidence of “damages of any kind.” If the only possible recoverable damages depended on the existence of one or the other of the two specified criteria'-, there was no object in referring to other evidence of other damages of some other kind. We may note, in passing, that the case is distinguishable from all those of the class where plaintiff is engaged in marketing the patented article or in using the patented process and in marketing the product, because in these cases there is from defendant’s competition necessarily an “impairment of the plaintiff’s market.” The particulars and the precise extent of that impairment may be impossible to prove, but that the impairment exists no one can doubt. We also note, with the greatest deference, that even when plaintiff is not himself marketing his device, nor practicing his process, it is often a fallacy to suppose that defendant’s infringement does not “impair plaintiff’s market.” The patentee’s exclusive right to the market extends for seventeen years; he is not obliged to find or create and to supply the demand at once; he may have good reasons, of policy or of necessity, for postponing his efforts; but the whole market for the whole period, nevertheless, belongs to him; and by so much as the infringing defendant supplies that demand and permanently fills that market before plaintiff offers to do so, by so much is plaintiff’s eventual market impaired. As to articles of long life and to be sold in a limited field this eventual impairment would be about the same whether plaintiff, in the early years of his patent, was or was not manufacturing; as to articles of short life and of less limited demand, the impairment would be much less; but it always would be existent, theoretically, and often, practically. Judge Severens’ comments in Brennan v. Dowagiac, supra,
“A patentee may withhold the exploiting of his patent in a particular territory, or he may not be able at the time to extend his business therein. But this gives no right to an infringer to invade the territory and anticipate the sales which the patentee might make when he should desire and be able to carry his invention there for a profit which is legitimately his own. * * * The fact that the owner of a patent does not exercise his right, or cannot at the time do so to the full, gives no license to another, and the latter is liable for infringement, to the same extent as if the owner were exercising his right to the utmost. The owner has the same right as he has to any other property, which he may put to use or not as he chooses; and in such case the rule al*624 ways is that, if a stranger without right seizes and uses it, he is hound to pay for such use, and it is no answer for him to say that the owner was doing nothing with it. If it be true, as has often been declared, that the exclusive right of a patentee is property, for the protection of which the public faith is pledged, it should have the same immunity from invasion, and its violation should be attended with the same consequences as in the case of other species of property.”
In view of the facts before the court in Coupe v. Royer, and the form in which the pronouncement on the question was made, we cannot believe that the case should be taken as intended to overrule, without naming it, a decision so important and so generally followed as Suffolk v. Hayden. In this conclusion, we do not stand alone. The question arose almost immediately and was presented to Circuit Judge (now Mr. Justice) McKenna. He considered it exhaustively in Cassidy v. Hunt (C. C.)
In McCune v. B. & O. R. Co., supra, the Circuit Court of Appeals for the Third Circuit considered the same question and reached the same conclusion, although without reference to Cassidy v. Hunt. Judge Buf-fington’s opinion is clear and persuasive.
On the other hind, opinions of the Circuit Courts of Appeals in the First, Second, Fifth, Eighth, and Ninth Circuits indicate that the authority of Suffolk v. Hayden is weakened or gone. It is noteworthy that the Circuit Court of Appeals for the Ninth Circuit, in Seattle v. McNamara,
Upon this review of the rules of damages and the decisions affecting this particular question, we are the better satisfied to adopt the conclusion of Judge McKenna and Judge Buffington and to hold that a “reasonable royalty,” if the proper foundation is laid and if the primary measures cannot be adopted, may become the applicable criterion in an action at law. If this is true, the same result follows before a master in determining damages in an action in equity. It is settled in this court that the damages and the profits contemplated by the statute are quite distinct and separate (Yesbera v. Hardesty [C. C. A. 6]
“There is no conceivable reason why the damages sustained by a patentee from the infringement of his patent are not the same whether he proceeds at law or in equity.”
The amount of plaintiff’s loss by the infringement, or, more specifically and in certain cases, the amount of a “reasonable royalty,” is a question of fact. It may be determined by a master just as by a jury.
We have before us only the question of recovery of legal damages; there has been no reason to consider the recovery of the profits which the defendant has made as a trustee. The practical difficulties attending the patentee upon the two- branches of recovery are somewhat analogous; and it was clearly in recognition of the unfortunate situation on the second branch that the Supreme Court, in Westinghouse v. Wagner,
The present case impresses us as one which may be suitable for the application of this rule; although whether it is or not we cannot now decide. It is enough to say we see a fair probability that plaintiff might be able to put- in proofs affording a sufficient basis for a reasonably accurate estimate of the damages which plaintiff’s business suffered by reason of the infringement, and the case, upon the Frumentum Company’s appeal, is reversed and remanded for that purpose only, but without costs. Upon the Eauhoff appeal, the case is affirmed, with costs.
Notes
We have twice met the question, but passed It without discussion. McSherry v. Dowagiac,
Later, the master reported a “reasonable royalty,” and judgment was entered. The Supreme Court (Rude v. Westcott,
