1. Patents—Compensation fob use of—Estoppel.The action was brought to recover the reasonable value of a license to use two patented processes relating to the manufacture of ropes and yarns, and familiarly known as the tar and the oil processes, under an alleged license from the plaintiff to the defendants. This is the theory of the complaint. Upon the trial the plaintiff had a verdict upon the theory that pursuant to an agreement made between him and the defendants lie, as the superintendent of defendant’s factory, was to use the said patented processes in the business of the defendants and for a reasonable compensation over and above his regular salary. No claim was made by the defendants at any time during the trial that they were in any way surprised by the proof, and all the evidence to prove the plaintiff’s case was admitted without objection on the part of the defendants that it varied from the complaint. Under these circumstances it was too late for the defendants to attempt to raise the point after the close of the testimony on both sides. Even then they did not claim that they had been surprised. Moreover, there was no variance between the allegations of the complaint and the proof sufficient to call for a reversal of the judgment. The proof abundantly established that the plaintiff was employed to use in the business of the defendants certain processes
The defendants, having contracted with the plaintiff for the use of his patents, and agreed to pay him a compensation therefor, cannot set up the invalidity of the patents as a defense to the action to recover the compensation. Hyatt v. Ingalls, 49 N. Y. Superior Ct., 375; aff’d 124 N. Y., 93 ; 35 St. Rep., 114 . It is not necessary, as happened to be the additional fact in Hyatt v. Ingalls, that the defendants should have bound themselves by the •express terms of their agreement not to question the validity of the plaintiff’s patents, for even without such a clause they are estopped. Saltus v. Belford Co., 133 N. Y., 499 ; 45 St. Rep., 872 .
Nor is it necessary to show an express agreement to pay for the use or an agreement for a fixed sum. An action will lie to recover the reasonable value of the use of a patent where the patent has been used under such circumstances as are sufficient to warrant the 'inference of an implied agreement to make compensation for the use. United States v. Palmer, 128 U. S., 262 ; Packet Company v. Sickles, 19 Wall., 611 .
The defendants insist, however, that even if they were estopped from raising at the trial the point of the invalidity of the patents as a complete defense to plaintiff’s cause of action, evidence of the validity, or invalidity, of the plaintiff’s patents was material as affecting the value of the use of the patents. The action is not for a fixed license fee, but for the reasonable value of the license during a certain period. The defendants never promised a definite sum. In such a case the validity, or invalidity, of the patent ordinarily has an important bearing on the amount of the value to be recovered. But in the present case such proof became immaterial for the following reasons:
For the year preceding the period in controversy here there was a written contract in force between the parties, under which the defendants were bound to pay to the plaintiff for the use of his patents ten per cent of the value of the gain in weight of the goods manufactured. Rope is sold by weight, that is, at so much a pound, and it was considered that if any of plaintiff’s processes would take the same amount of raw material, that is, so much hemp or sissal, and make out of it more pounds of rope than could be obtained by the old method, the gain in weight so obtained would be the direct profit of the process.
Under this contract the plaintiff did use his processes and with
This was all the defendants were entitled to. No request was made that any other question of fact should be submitted. The period for which compensation was claimed consisted of six-months and fifteen days, and under the instructions given to them the jury found a verdict of $3,136. There is sufficient evidence to sustain the verdict for this amount.
The parts of the contract with the National Cordage Company, which were admitted in evidence, were evidently admitted to contradict the testimony of one of the defendants upon a material point, and for this purpose the evidence was competent.
Upon a careful review of the whole case no exception has been found which calls for reversal.
The judgment and order should be affirmed, with costs.
