1. The appellant contends that the contract sued on is void because of uncertainty as to the quantity which he should purchase and the price which he should pay for the goods bought thereunder. This court cannot say as a matter
2. Appellant next contends that the contract is void for want of mutuality. In support of such claim it is urged that the plaintiff is seeking by injunction to enforce the negative covenant in the contract not to sell the goods of other manufacturers, that specific performance could not be enforced by defendant should plaintiff refuse to perform, and that unless there is mutuality of remedy- as well as of obligation equity will not interfere. It has already been said that there is mutuality of obligation under this contract. It is not necessary that there should also be mutuality of remedy in order to enable the plaintiff to enforce such,a negative covenant as is found in the contract sued on. It is so held in a case involving the same contract as is here involved, except that the pur^ chaser was different. Butterick P. Co. v. Fisher,
3. It is next contended that the contract is in restraint of trade and that it therefore violates the provisions of sec. 1770g, Stats. (Laws of 1905, ch. 506, sec. 2), and is void. While, under the patent laws, a patent creates a monopoly, it is not a monopoly of what existed before and belonged to others, which is the true idea of a monopoly, but it is a monopoly of what did not exist before and what belongs to the patentee. In consequence it does not create an odious monopoly, and the rights of patentees thereunder are to be liberally construed. 30 Cyc. 816, and cases cited. The patentee of an article may sell it to whom he pleases or may refuse to sell it at all. He may stipulate the retail price at which the purchaser from him may sell the article, and may lawfully obligate a special agent appointed by him to sell his article to the exclusion of other articles of a like character. Edison P. Co. v. Kaufmann,
4. It is next urged upon us that the action is not maintainable because the plaintiff has an adequate remedy by an action at law to recover the damages sustained by reason of the-breach of the contract. From a practical standpoint it would be impossible to measure the damage which plaintiff might sustain by reason of the defendant advertising patterns made-by a rival company that was a competitor of plaintiff. So, too, the loss which plaintiff might sustain by reason of the defendant selling other makes of patterns would be most difficult of ascertainment, if it could be shown at all with sufficient certainty to be made the basis of a claim for damages. The-objection that there is an adequate remedy at law will not defeat a suit in equity, unless the legal remedy is as- adequate, comprehensive, and effectual as that afforded by a court of equity. Lawson v. Menasha W. Co.
5. Lastly it is argued that the real remedy sought to be enforced amounts to an attempt to compel the defendant, by indirection, to perform an executory contract calling for personal services, and the case of Chain B. Co. v. Von Spreckel-.sen,
By the Court. — Order affirmed.
