after making the above statement, delivered the opinion of the court.
1. Motion is made by defendants to dismiss this appeal upon the ground that no appeal was taken, and no certificate of the trial court upon the question of jurisdiction, was made by such court during the term at which the decree was rendered ; and that no such certificate has since or ever, been made.
. As the appeal was taken directly to this court, it must appear, under the fifth section of the Court of Appeals act, either that the question of jurisdiction was certified to this court, or that the decree appealed from shows upon its face that the sole question decided was one of jurisdiction. Plaintiff evidently supposed that the case was a proper one to carry to the Court of Appeals, but its appeal having been there dismissed, it took this
*285
appeal May 27, 1901, from the original decree of the Circuit Court made November 5, 1900. This decree, after reciting “ that said suit does not really and substantially involve a dispute or controversy properly within the jurisdiction of this court, and that this .court should not further exercise jurisdiction, it is therefore ordered and decreed that said suit be and the same is hereby dismissed for want of jurisdiction.” An appeal was taken from this decree, and the order allowing the appeal states that the appeal was allowed “from the final order and decree dismissing said suit for want of jurisdiction.” This is clearly a sufficient certificate of the Circuit Court that the jurisdiction of that court was in issue, and the only question to be considered by us relates to the jurisdiction of that court.
Shields
v. Coleman,
The case, being thus in proper condition for appeal, such appeal could be taken at any time within two years.
Allen
v.
Southern Pacific Railroad,
2. The most important question is whether this is a suit under the patent laws of the United States within the meaning of K,ev. Stat. sec. 629, sub. 9, which grants original jurisdiction to the Circuit Courts
“
of all suits at law or in equity arising under the patent or copyright laws of the United States.” The rule is well settled that, if the suit be brought to enforce or set aside a contract, though such contract be connected with a patent, it is not a suit under the patent laws, and jurisdiction of the Circuit Court can only be maintained upon the ground of diversity of citizenship. But difficulties sometimes arise in determining whether the action be upon a contract or upon the patent. The first case involving this question was
Wilson
v.
Sandford,
Now, as the bill in this case differs from an ordinary bill for infringement only in the fact that the suit is by a licensee against two defendants, one of whom is the licensor and owner of the patent, and the license is set forth only for the purpose of showing title, there would be no difficulty whatever in sustaining it, were it not for the question whether we are not also bound to consider the averments of the answer. We think this difficulty is practically settled by a reference to section-5 of the Jurisdictional Statute of 1875, 18 Stat. 470, 472, which provides “that if, in any suit commenced in a Circuit Court, ... it shall appear to the satisfaction of the said Circuit'Court,
at any time after such suit has been brought, . .
. that such suit does not really and substantially involve a dispute or controversy properly within the jurisdiction of said Circuit Court, . . . the said Circuit Court shall proceed no further therein, but shall dismiss the suit,” etc. While it seems reasonable to say that a jurisdiction once acquired by the filing of a proper bill ought not to be taken away by any subsequent pleading, the statute is peremptory in this particular, and requires the court to dismiss the case whenever
at any time
it shall appear that its jurisdiction has been improperly invoked. We are by no means without authority upon this question. In
Robinson
v.
Anderson,
Is there anything in the answer to show that the court was bound to dismiss the bill for want of jurisdiction ?
The bill makes the usual allegations of a bill for infringement, and puts in issue (1) the title of the plaintiff, which in this case was a license from one of the defendants, fully set forth in the margin; 1 (2) the validity of the patent; and *289 (3) the infringement. The answer raises no issue as to the validity of the patent, or as to the acts charging infringement. It admits the license, but denies that it is a subsisting one, and pleads abandonment of the same by plaintiff, a forfeiture of all rights thereunder by failure to comply with its terms and conditions, and by acts of gross bad faith towards the patentee by seeking to defeat the patent, and a revocation of the license by Allen. It will be observed that the answer raises no question of the construction of the license, but merely of its existence— that is, of the title of the plaintiff to sue. Before deciding that these allegations oust the jurisdiction of the court it must at least appear that the plaintiff has another remedy by an action in a state court. But what remedy has it? All the *290 agreements and conditions of the license are such as are made by the plaintiff’s assignor, the Excelsior Redwood Company. This company, the party of the second part, agrees first, to pay a licensee fee or royalty, the time of payment being fixed in a subsequent sentence; second, that it will neither transfer nor assign the license without the consent of the patentee, (it was admitted that the patentee consented to the assignment to plaintiff): third, that in case the licensee should fail to use the patent in any pipe constructed by them, or from any cause it should cease to manufacture a wooden pipe, the license shall be at once revoked. The only clause in the license in which the patentee appears as promisor is that wherein “ he hereby grants, subject to the conditions hereinafter stated, unto the party of the second part, its successors and assigns, the exclu-. sive right, license and privilege within ” certain States “ of manufacturing and selling wooden pipe under and in accordance with the said letters patent to the full end of the term of said letters patent.”
Now, it may be freely conceded that, if the licensee had failed to observe any one of the three conditions of the license, the licensor would have been obliged to resort to the state courts either to recover the royalties, or to procure a revocation of the license. Such suit would not involve any question under the patent law. ■
But the same does not hold good with respect to the licensee. There were practically but two ways in which the patentee could impair the grant he made to the licensee, and those were by a revocation of the license by a bill in equity, or by treating it as abandoned and revoked, and granting a license to another party. He elected the latter remedy, and made a contract with the Pacific Bridge Company to make and sell wooden pipe within the same territory. A suit in a state court would either be inadequate or would involve questions under the patent law. If the licensee sued at law he would-be obliged to establish the fact that the patent had been infringed, which the patentee might have denied, and in any case could only recover damages for past infringements. If he sued in equity, he could only pray an injunction against future infringements; but this is exactly *291 •what he prays in this case, and thereby raises a question under the patent laws. In either case the patentee could defeat the action by showing that he did not infringe, — in either case the defendant could so frame his answer as to put in issue the title, the validity or the infringement of the patent.
The natural and practically the only remedy, as it seems to us, was for the plaintiff to assert his title under the license and to prosecute the defendants as infringers. In doing this he does what every plaintiff is bound to do, namely, set forth his title either as patenteé, assignee or licensee, and thereby puts that title in issue. The defendant is at liberty in such a case to deny the title of the plaintiff by declaring that the license no longer exists, but in our opinion this does not make it a suit upon the license or contract, but it still remains a suit for the infringement of a patent, the only question being as to the validity of plaintiff’s title. There can be no doubt whatever that if the plaintiff sued some third person for an infringement of his patent, the defendant -might attack the validity of his license in the same way, but it would not oust the jurisdiction of the court. Why should it do so in this case ?
Much reliance is placed upon the case of
Hartell
v.
Tilghman,
Plaintiff’s case was that there was a verbal agreement that he should prepare and put up his patented mechanism in defendants’ workshop, and that after this was done defendants should take a license for the use of the invention. The machinery was put up, but defendants refused to sign the license apparently upon the ground that the patentee claimed the right to visit the works of the defendants, and inspect their books with a view to ascertaining the amount of work done. The dispute was as *292 to the terms of the agreement, defendants insisting that they had never proposed to accept the license with the conditions mentioned. It was held that the patentee could not sue the defendants for an infringement, and in answer to the objection that he had no other remedy Mr. Justice Miller observed that he could establish his royalty once every year, and sue at law and recover every month or every year for what was due, and that, .if he desired to assert his right of examining the works of the defendants, he could in a proper case compel them to submit to the examination. The case is the converse of the one under consideration, inasmuch as it was a suit by the patentee against the licensee for a violation of his contract, and, as the Court observed, the plaintiff might have brought suit for royalties. As already said, the patentee might have done the same in this case, if he had sought to enforce his contract.
Much more nearly analogous to the case under consideration and practically upon all fours with it is that of
Littlefield
v. Perry,
*293 Upon the subjecc of a licensee suing his own patentee the Chief Justice observed : “ A mere licensee cannot sue strangers who infringe. In such cases redress is obtained through or in the name of the patentee or his assignee. Here, however, the patentee is the infringer, and, as he cannot sue himself, the licensee is powerless, so far as the courts of the United States are concerned, unless he can sue in his own name. A court of equity looks to the substance rather than form. When it has jurisdiction of parties it grants the appropriate relief without regard to whether they come as plaintiff or defendant. In this case the person who should have protected the plaintiff against all infringements has become himself the infringer.”
White
v. Rankin,
The cases in the Circuit Courts and Courts of Appeal are too numerous to be analyzed, or even cited. One 'of the most recent and satisfactory is that of the Atherton Machine Co. v. Atwood-Morrison Co., 102 Fed. Rep. 949, in which it was broadly held that a suit in which the relief sought is an injunction and a recovery of damages for the infringement of a patient is one arising under the patent laws .of the United States, although it incidentally involves a determination of the question of the ownership of the patent, which was claimed by both complainant and defendant under separate assignments from the patentee. All the cases cited herein are reviewed and the jurisdiction sustained.
The difficulty with the defendant’s position in the case under consideration is that it “apparently leaves the plaintiff without an adequate remedy. Defendant has broken no express covenant of the contract, since it has made no covenant. It has simply ignored the existence of the contract and granted a license to another party. It is difficult to see what remedy is available to the plaintiff in a state court that would not involve the right of the defendant to use the patent. In other words, it would be an ordinary suit for infringement in which the Federal courts would alone have jurisdiction. Whether it sued at law or in equity, its damages would be such as are *295 usual in cases of infringement, and the only injunction it could obtain would be against the further use of the .invention.
In any suit that could be brought the title of the plaintiff to sue must be put in issue, and, that being the title to the patent, is put in issue in every suit for infringement. We held in
Pratt v. Paris Light & Coke Co.,
While we do not intend to allow the jurisdiction of the Federal courts to be invoked primarily for the determination of the respective rights of parties to a contract concerning patents, yet when the bill is an ordinary one for an infringement and the answer puts in issue the title of the plaintiff to sue, we think the jurisdiction is not ousted by the mere allegation that the license has been revoked and that the court is at liberty to go on and determine that. fact. We regard this question as conclusively settled in
Littlefield
v.
Perry,
The decree of the Circuit Court is, therefore,
Reversed, and the case remanded for further proceedings consistent with this opinion.

“1 License and Agreement.
“ This agreement, made this 11th day of March, 1893, by and between Charles P. Allen, of Denver, Colorado, party of the first part, and the'Excelsior Redwood Company, a corporation duly organized and existing under and by virtue of the lav/s of the State of California, and having its principal place of business in the city and county of San Francisco in said State, party of the second part:
“ Witnesseth: That, whereas, the party of the first part is the owner and holder, for, to and in the States and Territories hereinafter mentioned, of the whole right, title and interest in and to letters patent of the United States, No. 359,590, dated March 22, 1887, for ‘wooden pipe.’
“And, whereas, the party of the second part is desirous of obtaining for, to and within the said States and Territories hereinafter mentioned an exclusive right, license and privilege to manufacture and sell wooden pipe under and in accordance with said letters patent:
*289 “Now, therefore, the parties have agreed as follows: The party of the first part hereby grants, subject to the conditions hereinafter stated, unto the party of the second part, its successors and assigns, the exclusive right, license and privilege, within the States of northern California, Oregon, Washington, Nevada, Montana and Idaho, and Territories of Arizona and Utah, of manufacturing and- selling wooden pipe under and in accordance with the said letters patent, to the full end of the term of said letters patent.
“ The party of the second part agrees to pay unto the party of the first paTt, as a license fee or royalty under this license and agreement, the following sums to wit: One dollar ($1.00) on every one thousand feet, board measure, of lumber employed in the manufacture of said pipe, and two and one-half per cent (2j- per cent) on the cost at factory of all steel and iron, used in said manufacture.
“ The said license or royalty is to be paid by the said party of the second part to the said party of the first part upon the final payment to the party of the second part of the contract price on each and every contract taken by said party of the second part, involving the manufacture and sale of said patented wooden pipe. The right, license and pri vilege hereby granted is not transferable or assignable, either in whole or part, by the party of the second part, without the consent of the party of the first part. It is agreed that in case the party of the second part shall fail to use the above-described patent in any pipe constructed by them, of twelve (12) inches diameter and upwards, or from any cause the said party of the second part shall cease the manufacture' of wooden pipe, then and in that event all rights and privileges granted by this agreement and license to the said party of the second part shall at once be revoked.
“ It is understood and agreed that this agreement is binding upon the heirs, legal representatives and assigns of the party of the first part, and upon the successors and assigns of the party of the second part.”
