Montgomery v. Waterbury
Opinion of the Court
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, he, as the superintendent of defendants’ 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. Ho claim was made hy the defendants at any time during the trial that they w.ere 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 in oil or tar which he had invented and for which he had applied for or obtained a patent, and that while the plaintiff had the right for the purposes of the contract to use any other processes which he might invent, yet as matter of fact no others were invented, and what the plaintiff was paid for at the end of the first year was for the use of his patented processes mentioned in
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. Super. Ct. 375 ; 124 N. Y. 93.
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 them 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.
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:
These facts now stand established by the verdict of the-
The parts of the contract with the Hational 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.
McAjdam and G-ildeesleeve, JJ., concur.
Judgment affirmed.
