This is an appeal of the National Marking Machine Company, the complainant, from an order *8 of the court below denying its motion for an interlocutory injunction against the defendant the Triumph Manufacturing Company and its officers, restraining them from selling the Bunker marking machines. The facts which condition the right in equity of the complainant to the injunction it seeks are set forth in its amended bill in equity, none of the averments of which were denied by answer, affidavit, or like showing on the part of the defendants.

On April 22, 1913, the United States issued to Chester W. Canine a pioneer patent on marking machines for laundries, the term of which expires in April, 1930. The plaintiff owned this patent, the defendants infringed it by the manufacture and sale of their Bunker marking machine. The plaintiff sued them for the infringement and obtained a final decree on October 9, 1919, whereby the court perpetually enjoined them and their officers and agents from making, using or selling to others their Bunker machine, or any of the devices described in certain claims of the patent to Canine, adjudged that the plaintiff was entitled to recover the profits they had made by the manufacture and sale of the Bunker marking machine, and the damages they had inflicted upon the plaintiff thereby, and referred the ease to a master to state the account of the gains and profits and assess the damages.

On November 5,1919, the plaintiff and defendant Triumph Manufacturing Company made a written contract to the effect that the defendant granted to the plaintiff the exclusive right to sell the Bunker machines on - terms and at prices described in the contract, whereby each of the parties would receive about $125 for each machine, to the effect that the plaintiff would promptly commence, carry on, promote, and bring about during the life of the contract sales of these Bunker machines, that the defendant would in good faith manufacture promptly and expeditiously these machines and fill orders of the plaintiff for them f. o. b. ears Kansas City, Mo. This contract provided that its life should be .five years from its date, November 5, 1919, and that, should it be terminated by limitation or otherwise, then the right and option was by the contract given to the plaintiff of continuing its life for an additional five years, provided that notice to that effect should be filed with the defendant six months prior to the expiration of the agreement. Such a notice was duly filed and the life of the contract continued until November- 5, 1929.

The contract also provided that, upon termination of the contract by limitation or -otherwise, the defendants should pay the 'plaintiff a royalty of 10 per cent, of the sale price of all the machines thereafter manufactured and sold by it, and that, should the icontract be terminated prior to the date of its termination by limitation as therein fixed 'due to the fault of the first party, the defendants should be entitled to $5,000. Another provision of the contract was that, in the event that any marking machine hereafter, and during the life of this contract, manufactured and placed upon the market by the defendant, shall infringe any letters patent now owned by the plaintiff, then, upon such determination, the defendant shall pay to the plaintiff a royalty thereon equal to 10 per cent, of the sale price of any and all marking machines so manufactured and sold.

A few days after the contract was made, the parties signed a stipulation wherein they recited that they had entered into this contract by which all questions of profits and damages had been settled, and by which the defendant was given the right to manufacture its marking machines in the future, and whereby they stipulated that “it is therefore hereby mutually agreed that the injunction heretofore ordered in this case may be dissolved, and that the accounting before a master, as in said decree provided, shall be waived.”

The parties to this agreement complied with its terms for more than five years, until some time in December, 1924, when and since the defendant has refused to fill the orders of the plaintiff for the Bunker machines, has notified prospective buyers that if they want Bunker machines they must order them from the defendant, and has sold such machines to such purchasers direct. For more than five years, commencing immediately after this contract was made, the plaintiff has conducted an expensive advertising campaign, informing laundry men of the merits, and advantages of the Bunker machines, has employed a large number of salesmen and sent them throughout the United States, and has thereby created and built up a valuable good will in its exclusive business of selling the Bunker machines, their parts and supplies. It has during that time sold such machines, supplies, and repairs therefor under the contract, worth about $250,000, and has paid to the defendants therefor about $150,000. The defendant, by its refusal to comply with the terms of the contract, has already greatly injured the good will of the plaintiff’s business, and, unless it is enjoined fronrcontinuing so to do, will destroy it, and *9 inflict upon the plaintiff irreparable injury and damages incapable of proof or measurement, and its course in selling these machines is an infringement upon the plaintiff’s exclusive right to sell all laundry marking machines secured to it by the patent to Canine.

There are some principles, rules, and practices in equity established beyond debate or tbe necessity for the citation of authority, and among them are these:

First. The owner of a patent, who has secured in a litigated case a final decree against an infringer that ho has the exclusive, separable rights (a) to manufacture, (b) to use, and (e) to sell tho infringing machine, and tho devices and inventions embodied therein and in like machines, is entitled to an injunction to prevent the infringer from making, using, or selling the infringing machine, or any of those rights.

Second. A parly to a contract, who has continually performed his part thereof, and is ready and willing to complete Ms performance, is entitled to a decree of specific performance thereof by Ms contractee, who has failed or is failing to perform Ms part thereof, unless the contractor has an adequate remedy at law for the eontractee’s breach. Joy v. St. Louis, 138 U. S. 1, 46, 11 S. Ct. 243, 34 L. Ed. 843; Leavitt v. Windsor Land & Investment Co., 54 F. 439, 442, 443, 4 C. C. A. 425; General Electric Co. v. Westinghouse Electric Co. (C. C.) 151 F. 664, 674, 679, 681; White v. Rankin, 144 U. S. 628, 635, 636, 12 S. Ct. 768, 36 L. Ed. 569; Hartell v. Tilghman, 99 U. S. 547, 549, 556, 25 L. Ed. 357.

Third. The adequate remedy at law, which will preclude the grant of specific performance of a contract by a court of equity, must be as certain, prompt, complete, and efficient to attain the ends of justice as a decree of specific performance. Boyce’s Ex’rs v. Grundy, 3 Pet. 210, 215, 7 L. Ed. 655; Williams v. Neely, 134 F. 1, 67 C. C. A. 171, 69 L. R. A. 232; Castle Creek Water Co. v. City of Aspen, 146 F. 8, 14, 76 C. C. A. 516, 8 Ann. Cas. 660. The facts of this ease leave no doubt that the plaintiff has no such remedy at law.

Fourth. An injunction against the breach or the continuance of a breach of a contract is a negative decree of specific performance, and the power and dnty of a court of equity to grant such an injunction is even greater, under the rules, principles, and practices in equity, than its power and duty to grant decrees of specific performance. A court of equity may issue its injunction to prevent a violation, or the continuance of a violation, of a contract in eases in which it would not decreo specific performance thereof. Chicago & A. Ry. Co. v. New York, L. E. & W. R. Co. (C. C.) 24 F. 516, 522; Lumley v. Wagner, 1 De G., M. & G. 604; Singer Sewing Machine Co. v. Union Buttonhole & E. Co., Fed. Cas. No. 12,904, 1 Holmes, 253; Western Union Tel. Co. v. Union Pacific Ry. Co. (C. C.) 3 F. 423, 429; Texas Co. v. Central Fuel Oil Co., 194 F. 1, 3, 23, 114 C. C. A. 21.

Counsel devote much time and attention to the questions whether this suit arises under the patent laws of the United States, or is based on diversity oC citizenship, and whether or not the contract is a license from the patentee. These questions might be material, if the jurisdiction of tho court below depended upon whether or not this case arises under tho patent laws of tho United States; but the plaintiff has not only set forth the suit for and tho decree of infringement, tho contract, and tho stipulation, but it has also alleged tho necessary diversity of citizenship of the parties to give the court plenary jurisdiction. These questions do not therefore seem to us material and wo dismiss them here.

In our opinion, the final decree of infringement, damages, and injunction, the contract of November 5, 1919, the performance of that contract by tbe plaintiff, and the breach and continuing violation of it by the defendant, condition tho power and the duty of the courts to grant the temporary injunction here sought. By the final decree, the exclusive right of the plaintiff (a) to manufacture, (b) to use, and (c) to sell the defendant’s Bunker marking machines and all other like machines was adjudged in the plaintiff, and tho defendant was perpetually enjoined from infringing it. The plaintiff is now seeking an injunction against the infringement of its right to sell the Bunker machine. That right was vested in it when it made the contract of November 5, 1919, and was also expressly confirmed to it by the defendant by the express terms of that contract.

Counsel for the defendant contend that the plaintiff lost this right by the stipulation for tbe dissolution of tho injunction granted by the final decree, and by the recital in that stipulation that the contract, which had. been made before the stipulation, gave to the defendant the right to sell tho Bunker machines. Tho contract itself, however, is better evidence than the subsequent recital of a part of it in the stipulation, and that contract and the parties’ construction of it, by *10 the manufacture by the defendant exclusively and by the sale by the plaintiff exclusively of the Bunker machines under it for more than five years, leave no doubt that the original exclusive right of the plaintiff to sell these machines remained in it when and ever since the contract was made.

Another contention of counsel for the defendants is that the stipulation of the parties dissolving the original injunction estops the plaintiff from successfully seeking the preliminary injunction it now desires. But the stipulation recites and the facts of this case demonstrate that this stipulation was made in consideration of the prior making of the contract by the defendant that it would manufacture and sell exclusively to the plaintiff the Bunker machines, and that the plaintiff would exclusively sell those machines to other purchasers. If the defendant had performed, and was ready and willing to perform, that contract, the plaintiff might be estopped from obtaining the injunction it seeks; but the defendant has violated that contract, it has induced the plaintiff, in reliance upon its promise to perform it, to expend many thousands of dollars to advertise and sell this Bunker machine, and to build up a valuable good will, from which it would have profited if the defendant had kept its promise, and then it has refused to manufacture and deliver these machines to the plaintiff as it agreed. By its violation of its contract it has not only deprived and is depriving the plaintiff of its lawful business, good will, and profits under this contract, but is appropriating all these and the benefits of the plaintiff’s advertising to itself. By these acts, by its continuing breach of its contract, it has estopped itself from taking any advantage thereof to prevent the plaintiff from obtaining the injunction it seeks to prevent the continuance of its violation of its agreement. The result is that the exclusive right of the plaintiff to sell the Bunker machines, which infringed the patent which the plaintiff owned, has been in the plaintiff from before the final decree was rendered, was expressly reserved to and confirmed in it by the terms of the contract of November 5, 1919, and seems to entitle it now to the temporary injunction it seeks. 32 Corpus Juris, 74.'

Moreover, the contract of November 5, 1919, the plaintiff’s performance thereof, and its readiness and willingness to continue to perform, the defendant’s breach and continuing violation thereof, the gross injustice of the defendant’s course, the inadequacy of the plaintiff’s remedy at iaw for this breach, and the appealing equities of its case seem to entitle it to the same relief.

Counsel for the defendant, however, argue that the provisions in the contract that, first, “upon termination of the contract by limitation or otherwise, second party [the defendant] shall pay first party [the plaintiff] a royalty of 10 per cent, of the sale price of each and all of said machines thereafter manufactured and sold by second party”; and, second, that “in the event any marking machine hereafter, and during the life of the contract manufactured and placed upon the market by second party, shall infringe any letters patent now owned by first party, then upon such determination, second party shall pay first party a royalty thereon equal to ten per cent, of the salé price of. any and all marking machines so manufactured and sold,” destroy the right of the plaintiff to any relief by injunction or otherwise in this ease, except to 10 per cent, of the purchase price of the machines sold by it after the defendant commenced to violate the provision of the contract that it would manufacture and the plaintiff should sell all the Bunker machines at the prices and on the terms specified therein.

But this interpretation of the agreement flies in the teeth of the evident intention and purpose of the parties, of the express contract that for ten years, the life of the contract, the defendant should make and the plaintiff should sell the Bunker machines, and the construction of that contract evidenced by the making and sales of the machines thereunder for more than five years after the contract was made. In our opinion the parties never contemplated or provided in this first provision for an unlawful breach of the contract by either of the parties, but only for a termination by limitation of the life of the contract specified therein or other lawful termination, and the life of the contract still continues.

Nor does the second provision quoted seem to us to govern or affect the manufacture or sale of the Bunker machines. In the first part of the contract, in the seventh paragraph thereof, the parties to it expressly agreed that all the Bunker machines should be made by the defendant and sold by the plaintiff at prices and terms there stated. This provision is in the tenth paragraph, where it provides that, “in the event any marking machines hereafter, and during the life of this contract manufactured and placed upon the market by second party, shall infringe any letters patent now owned by first party, then upon such determination,” the *11 second party should pay the 10 per cent, royalty. This provision could not have been intended to govern or refer to the Bunker machines, because by the express terms of the seventh paragraph they could not be “placed upon the market by second party” • without a breach of that paragraph, and because it was only “upon such determination” that they infringed that the royalty on the machines referred to in this tenth paragraph was to be paid, and the determination that the Bunker machines infringed had been determined by final decree before the contract was made.

The principles, rules, and practices of equity jurisprudence, to which reference has been made, and the indisputable facts of this case, invoke the jurisdiction and impose the duty upon this court to reverse the order denying the application for a temporary writ of injunction, and to remand this case within ten days after the entry of the order or decree of this court to the court below, with directions to grant the application for the injunction and take such further proceedings as may be consistent with the views expressed in this opinion. And it is so ordered.
