delivered the opinion of the court'.
This is а bill in equity brought by the appellee, an Illinois corporation, against The Fair, also an Illinois corporаtion, for an injunction against The Fair’s making and vending certain; patented gas heating devices, or selling such deviсes of the plaintiff’s manufacture at less than one dollar and a half 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 devicеs throughout the United States and that the defendant with full notice has sold and is selling the same without license . in violation оf the plaintiff’s right. . It then.goes on to, allege that the .plaintiff, when it sells, imposes the condition that the goods shall nоt be sold at less than one dollar and fifty cents, and attaches to the goods a notice to that *24 effect and that any salé in violation of the condition, or use of the article 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 a dollar and a quarter each in infringement of the plaintiff’s rights under the patent.
The Fair , appearеd specially and pleaded that all the devices in question sold by it were purchased from the plaintiff by a jоbber, that the jobber paid the full price .to the plaintiff, that upon these facts there was no question arising undеr the patent or other laws of the United States, ánd that-the court had no jurisdiction of the case. The casе was set down for hearing on the plea, so that the foregoing allegations of fact must be taken to be true.

v.
Kittson,
Obviously the plaintiff sued upon the patent law, so far as the purport and intent of the bill- is concerned. It .was a resident of the same State as-the dеfendant and could have had no other ground. In’ the earlier paragraphs of the bill it charged an infringement оf its patent rights in general terms, aiiddt sought triple damagés, which it could have done only by virtue, of the statute. It is true that-latеr it set up the. sale at a dollar and a. quarter as an infringement and that we may guess that this is the only one, although.it dоes not say so. But if that, is the plaintiff’s *25 only cause of action, still the plaintiff relies upon it as an •infringement and nothing еlse — 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 defence even when anticipated and replied to. in the bill.

Thus in
Vicksburg Waterworks Co.
v.
Vicksburg,
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 purchasеrs of the device. The plaintiff no doubt maintains that the law does give him that right, ánd that even if the alleged infringements arе 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.
