THE FAIR, Appt.,
KOHLER DIE & SPECIALTY COMPANY.
Argued and submitted March 6, 1913.
Decided March 24, 1913.
Messrs. David S. Wegg and Walter H. Chamberlin for appellant.
Messrs. Frank T. Brown and Francis A. Hopkins for appellee.
Mr. Justice Holmes delivered the opinion of the court:
This is a bill in equity, brought by the appellee, and Illinois corporation, against the Fair, also an Illinois corporation, for an injunction against the Fair's making and vending certain patented gas heating devices, or selling such devices of the plaintiff's manufacture at less than $1.50 each; for an account and for triple damages. The bill alleges that the plaintiff has the sole and exclusive right to make and sell the devices throughout the United States, and that the defendant, with full notice, has sold and is selling the same without license, in violation of the plaintiff's right. It then goes on to allege that the plaintiff, when it sells, imposes the condition that the goods shall not be sold at less than $1.50, and attaches to the goods a notice to that effect, and that any sale in violation of the condition, or use of the aritcle, if so sold, will be an infringement of the patent. It further avers that the defendant obtained a stock of the devices with notice of the conditions, and sold them for $1.25 each, in infringement of the plaintiff's rights under the patent.
The Fair appeared specially and pleaded that all the devices in question sold by it were purchased from the plaintiff by a jobber, that the jobber paid the full price to the plaintiff, that upon these facts there was no question arising under the patent or other laws of the United States, and that the court had no jurisdiction of the case. The case was set down for hearing on the plea, so that the foregoing allegations of fact must be taken to be true. Farley v. Kittson, 120 U. S. 303, 314, 30 L. ed. 684, 688, 7 Sup. Ct. Rep. 534. The court, in deference to Victor Talking Mach. Co. v. The Fair, 61 C. C. A. 58, 123 Fed. 424, maintained its jurisdiction, and as the defendant did not answer within the time allowed, took the bill as confessed and made a decree for the plaintiff. The judge stated that he did not feel at liberty to give a formal certificate, but added what appears from the record, that the defendant did nothing except to file the above plea. The appeal is upon the question of jurisdiction alone. There is no uncertainty or ambiguity, and we are of opinion that the case is properly here. Petri v. F. E. Creelman Lumber Co. 199 U. S. 487, 492, 50 L. ed. 281, 284, 26 Sup. Ct. Rep. 133.
Obviously the plaintiff sued upon the patent law, so far as the purport and intent of the bill is concened. It was a resident of the same state as the defendant, and could have had no other ground. In the earlier paragraphs of the bill it charged an infringement of its patent rights in general terms, and it sought triple damages, which it could have done only by virtue of the statute. It is true that later it set up the sale at $1.25 as an infringement, and that we may guess that this is the only one, although it does not say so. But if that is the plaintiff's only cause of action, still the plaintiff relies upon it as an infringement and nothing else; so that, good or bad, the cause of action alleged is a cause of action under the laws of the United States.
Of course, the party who brings a suit is master to decide what law he will rely upon, and therefore does determine whether he will bring a 'suit arising under' the patent or other law of the United States by his declaration or bill. That question cannot depend upon the answer, and accordingly jurisdiction cannot be conferred by the defense, even when anticipated and replied to in the bill. Devine v. Los Angeles, 202 U. S. 313, 334, 50 L. ed. 1046, 1053, 26 Sup. Ct. Rep. 652. Conversely, when the plaintiff bases his cause of action upon an act of Congress, jurisdiction cannot be defeated by a plea denying the merits of the claim. It might be defeated, no doubt, in a case depending on diversity of citizenship, by a plea to the citizenship of parties. Interior Constr. & Improv. Co. Gibney, 160 U. S. 217, 219, 40 L. ed. 401, 402, 16 Sup. Ct. Rep. 272. We are speaking of a case where jurisdiction is incident to a Federal statutory cause of action. Jurisdiction is authority to decide the case either way. Unsuccessful as well as successful suits may be brought upon the act, and a decision that a patent is bad, whether on the facts or the law, is as binding as one that it is good. See Fauntleroy v. Lum, 210 U. S. 230, 235, 52 L. ed. 1039, 1041, 28 Sup. Ct. Rep. 641. No doubt if it should appear that the plaintiff was not really relying upon the patent law for his alleged rights, or if the claim of right were frivolous, the case might be dismissed. In the former instance the suit would not really and substantially involve a controversy within the jurisdiction of the court 'Excelsior Wooden Pipe Co. v. Pacific Bridge Co. 185 U. S. 282, 287, 288, 46 L. ed. 910, 913, 914, 22 Sup. Ct. Rep. 681), and in the latter the jurisdiction would not be denied, except, possibly, in form (Deming v. Carlisle Packing Co. 226 U. S. 102, 109, 57 L. ed. ——, 33 Sup. Ct. Rep. 80). But if the plaintiff really makes a substantial claim under an act of Congress, there is jurisdiction whether the claim ultimately be held good or bad.
Thus, in Vicksburg Waterworks Co. v. Vicksburg, 185 U. S. 65, 68, 46 L. ed. 808, 809, 22 Sup. Ct. Crep. 585, it was pointed out that, while the certificate inquired whether a Federal question was involved upon the pleadings, and while the counsel had argued the merits of the case, the function of this court 'is restricted to the inquiry whether, upon the allegations of the bill of complaint, assuming them to be true in point of fact, a Federal question is disclosed so as to give the circuit court jurisdiction in a suit between citizens of the same state.' For that reason the court declined to pass upon the validity of the contract the obligation of which was alleged to have been impaired. Id. 82, s. c. 202 U. S. 453, 458, 50 L. ed. 1102, 1106, 26 Sup. Ct. Rep. 660, 6 Ann. Cas. 253; Mertantile Trust & D. Co. v. Columbus, 203 U. S. 311, 322, 323, 51 L. ed. 198, 203, 204, 27 Sup. Ct. Rep. 83; Knoxville Water Co. v. Knoxville, 200 U. S. 22, 32, 50 L. ed. 353, 358, 26 Sup. Ct. Rep. 224.
In this case the plea, though purporting to go to the jurisdiction of the court, merely means that the patent law does not give a patentee a right to impose such a condition as the plaintiff attempted to impose upon second purchasers of the device. The plaintiff no doubt maintains that the law does give him that right, and that even if the alleged infringements are confined to the acts admitted by the plea, they are infringements none the less. The bill hardly can be confined to that claim, but if it were, it is made in good faith and is not frivolous, it is a claim of right under the patent law, and the circuit court properly took jurisdiction of the case.
