after stating the case as above, delivered the opinion of the court.
The primary question on an appeal from an order granting a temporary injunction is whether or not the injunction evidences an error in the exercise of its sound judicial discretion by the court which issued it. 'Hiere are established legal principles for the guidance of that discretion, and where they are violated the action of the court below should be corrected. But, unless there is a plain disregard of some of the settled rules of equity which govern the issue of injunctions, the orders of the courts below on this subject should not be disturbed. The law has placed upon these courts the duty to exercise this discretion. It has imposed upon them the responsibility of its exercise wisely, and has left them much latitude for action within the rules which should guide them; and, if there has been no violation of those rules, an appellate court ought not to interfere with the results of the exercise of their discretion. The right to exercise this discretion has been vested in the trial courts. It has not been granted to the appellate courts, and the question for them to determine is not how they would have exercised this discretion, but whether or not the courts below have exercised it so carelessly or unreasonably that they have passed beyond the
The complainant applied, upon an adjudicated patent, for an injunction to restrain the Stearns-Roger Manufacturing Company and the Portland Gold Mining Company from constructing and using their Pearce, turret ore-roasting furnaces which the manufacturing company was building under a contract with the mining company, ánd which, the mining company intended to use when they were' completed. He also asked for a general injunction against the manufacture, sale, or use by the defendants of any of the Pearce furnaces. The court refused to issue any-injunction against the mining company. It refused to enjoin either company from constructing and using the three furnaces in process of erection. But upon the execution and filing of a bond in the sum of $10,000 to indemnify the manufacturing company for any damages it should sustain if the preliminary injunction was subsequently dissolved or modified, it enjoined the manufacturing company from making or vending any more Pearc.e furnaces until the final determination of this suit. This does not seem to be an unjust or an unreasonable course of action. The mining company took and has prosecuted a separate and independent appeal from the order granting the injunction against the manufacturing company. But as the injunction does not restrain the mining company from doing any act either alone or jointly with the manufacturing company, the mining company could not have been legally aggrieved by the order, and it had no right to appeal from it. Its appeal is accordingly dismissed.
The remaining question is whether or not the order enjoining the manufacturing company during the pendency of this suit from building and selling more Pearce furnaces after it installed the three that were contracted to the mining company was an unlawful exercise of the discretion of the circuit court. Counsel for the manufacturipg company insist that this order was violative of the established rules of equity .jurisprudence, because the Pearce furnace was not an infringement upon the patent to Brown, because the complainant had been guilty of such laches that he was not entitled to an ad interim injunction, and because there was no proof that the complainant would sustain such injury from the continued infringement as would warrant an injunction. The crucial question in this case — the question which must ultimately determine it on the merits — is whether or not the manufacture, sale, and use of the Pearce furnace is an infringement upon Brown’s monopoly. There are cases in which the question of infringement may be finally determined on appeals from orders granting temporary injunctions, and where this can be done it is always competent, and often prudent, for an appellate court to consider and decide it on such an appeal. But this is not one of those cases. The complainant properly joined the manufacturing company and the mining company as defendants in this court, because they were jointly making and preparing to use the three Pearce iurnaces which they were about to install in the new mill of the mining company. The mining company has answered that these furnaces do not infringe upon the patent to Brown, and it is entitled to a decision of that issue upon the evidence and testimony
Counsel for the manufacturing company invoke the conceded rule that, where it is not clear that the defendant is guilty of infringement, and that question is grave and difficult, a temporary injunction should not be granted on ex parte affidavits. Sprague Electric Ry. & Motor Co. v. Nassau Electric R. Co.,
It is contended that the complainant was guilty of such laches that he was not entitled to a preliminary injunction. The patent in suit was issued on March 22, 1892. In May, 1893, the owner of the patent notified the manufacturing company or its predecessor that its Pearce- furnace was an infringement, and in June that charge was denied. On January 4, 1897, Brown brought his suit against the Metallic Extraction Company, in which, after a protracted and expensive litigation, the validity of his patent was finally established on October 8, 1900. Extraction Co. v. Brown,
Finally, it is contended that the order granting the injunction should be reversed because there was no proof of such threatened irreparable injury to the plaintiff as would warrant it, while there was evidence that the manufacturing company was solvent, and that the issue of the injunction would cause it great loss. A continuing-trespass is always good ground for the issue of an injunction in the absence of countervailing considerations, because a multiplicity of suits for damages is never an adequate remedy for the loss which constantly repeated trespasses entail. Upon this ground, in the absence of other considerations, the complainant was entitled to his injunction. Manufacturing Co. v. Booth,
