This suit is brought to restrain the infringement of tbe complainant’s patent for an improvement in lubricators. The bill, besides setting out such facts as are ordinarily alleged, showing title and acts of infringement by tlic defendants, sets out also, by way of anticipating the defense, that the defendants are selling lubricators manufactured by the Detroit Lubricator Company, which sale constitutes the infringement complained of, and pretend that they have a right to sell the same without suit by or molestation from the complainant, because on or about the first day of December, 1883, the complainant and the *626said Detroit Lubricator Company made an agreement in writing wherein it was covenanted that “so long as the covenants and agreements to be observed and performed by the parties, respectively, are observed and performed, each party agrees not to sue, or directly or indirectly authorize to be sued, the other party, its agents or vendees, under any of the letters patent now or hereafter owned by it.” The bill further alleges that the defendants pretend that the said agreement is still in force, and further alleges that such pretense is unfounded, because the said Detroit Lubricator Company did not observe and perform certain covenants on its part in the agreement contained, and the agreement was annulled and rescinded prior to the commencement of the suit. The defendants have interposed a plea tp the bill, in which they set up the agreement between the complainant and the Detroit Lubricator Company as a defense to the suit, and aver that said agreement is still in force. The complainant has moved for a preliminary injunction, and the defendants have moved to'dismiss the bill, upon the ground that the suit is not one arising under the patent laws, and the bill does not contain the requisite averments to give the court jurisdiction otherwise.
It is apparent from the affidavits presented upon the motion for an injunction that the real dispute between the parties is whether the covenant not to sue, contained in the agreement between the complainant and the Detroit Lubricator Company, is still in force, or whether that covenant, and one other covenant in the agreement, on the part of the Detroit Lubricator Company, to make monthly returns and payments to the complainant for the sale of lubricators, are'at an end; the contention on the part of the defendants being that the Detroit Lubricator Company was released from its covenant to make returns and pay royalties, because the complainants had previously violated a condition of the agreement on its part not to authorize by license the use of its patents outside of the New England states, and had licensed the Nathan Manufacturing Company to use its patent. No issue is made by the pleadings, nor is any presented by the affidavits respecting the validity of the patent in suit, the complainants’ title thereto, or the acts of infringement by the defendants. And it is conceded in behalf of the complainant that the bill cannot be maintained, and that the motion of defendants to dismiss it on the ground of want of jurisdiction should prevail, unless the controversy made by the bill and plea is one arising under the patent laws.
It is doubtless true that the covenant on the part of the complainant not to sue is equivalent to a license to the Detroit Lubricator Company and its vendees to use the patented invention, and protects them as effectually as an express license, so long as the Detroit Lubricator Company observes the conditions upon which the covenant is to continue in force. Nevertheless, the case caja be distinguished from Hartell v. Tilghman, 99 U. S. 547, and other eases decided upon the authority of that decision, including Trading Co. v. Glaenzer, 30 Fed. Rep. 387, because the action is not, in substance, one to prevent the violation of the rights of a patentee or owner of a patent under a contract of which the patent is the subject-matter, but is the ordinary action to prevent the violation *627of a right secured by a patent which the defendant seeks to defeat by a collateral covenant; and, until the supreme court shall otherwise decide, the doctrine of Hartell v. Tilghman should not be extended to a case like the present.
It would seem that an action could be maintained on the law side of this court to recover damages for the infringement in question, and, although the defendant should in such an action rely upon the covenant not to sue as the only defense, setting it up in his answer, while admitting every fact averred in the complaint, he could not thus oust the court of jurisdiction. Although the only issue would be whether the covenant was in force, and a bar to the action, the action would nevertheless be one arising under the patent laws of the United States, and the defendant could not oust the court of jurisdiction by any admission he might see lit to make in his pleadings. If this court would have jurisdiction of the action on the law side, it has on the equity side when the relief sought is an injunction, and the facts authorize such relief. Certainty, jurisdiction is not defeated because the complainant alleges, in addition to the ordinary averments entitling him to the relief sought, such facts, byway of anticipation, as are essential to enable him to controvert the facts which the defendant may present by a plea or an answer. In the present ease the complainant would not be at liberty to show that the covenant not to sue is not in force, because the Detroit Lubricator Company lias not observed some condition in the agreement upon which the covenant is to cease, or at least it is doubtful whether the complainant could do so. Although formerly a complainant by a special replication could put in issue some fact on his part necessary for the evidence of new matter in the defendant’s plea or answer, but not alleged in the bill, this is not now permissible. Equity Rule 45. It is needless to say that no facts are properly in issue unless charged in the bill. Story, Eq. Pl. §§ 257, 878.
If this court has no jurisdiction of the controversy, the complainant would seem to be without remedy, because by the decisions of the state court of last resort it is held that in such a case he can and must resort to this court, and that the state courts have no jurisdiction. Store Service Co. v. Clark, 100 N. Y. 365, 3 N. E. Rep. 335; Manufacturing Co. v. Reinoehl, 102 N. Y. 167, 6 N. E. Rep. 264.
Upon the facts appearing in the affidavits, the case is one where the motion for an injunction should be granted, unless the defendants execute an undertaking conditioned to secure the complainant for the amount of any decree which may be recovered in the action. As the Detroit Lubricator Company is the real defendant, that corporation must file monthly reports henceforth with the clerk, as provided in the agreement between it and the complainant, and also a report of all lubricators containing the patented invention sold since it ceased to file monthly reports, as a condition of withholding the injunction.
