delivered the opinion of the court.
This is an appeal from an order of the superior court of Cook county overruling a demurrer to a bill of complaint which alleged, in substance, that on and prior to January 23, 1919, the complainant was engaged in the business of manufacturing and selling journal packing under certain letters patent of the United States; that on said date she entered into a license contract with Eugene C. Hall and Charles A. Elsy, under which they and their assigns were given an exclusive right under the letters patent to manufacture and sell journal packing for royalties provided for in the contract. A material part of this contract' is as follows:
“5. In default of payment of royalty based on ten thousand pounds per month sold the following stipulation is to be in full force and effect, that is to say, upon default the purchasers shall forfeit, at the option of the vendor, all of the rights and privileges obtained to them by virtue of this contract and all rights to sell and manufacture shall reinvest in the vendor; and the vendor shall at her option, have the right, upon thirty 'days’ written notice, to seize and take possession of all the goods, wares, merchandise, machinery and other assets which have been held and owned by the purchasers for the exclusive purpose of carrying on the manufacture of the within described goods, subject however to liabilities.
“6. Said stipulation number five is made and accepted in lieu of liquidated damages in the event of the default of the payment of royalties heretofore described in stipulation number three.”
The bill further charged that the defendants had defaulted in the payment of royalties; that complainant had given notice of her election to terminate the con*117tract; that defendant, Rogers’ Journal Packing Company, and W. H. Hall, one of its officers, as well as tlie other defendants named, claimed that the defendant company is an assignee of the licensee defendants, and that the defendants claimed to control absolutely the patent and all rights thereunder and were advertising in trade journals; that defendants had refused to reassign the license contract to complainant and were making fictitious and unfounded claims to rights thereunder ; that complainant has suffered great loss thereby and that the contract of assignment to certain of the defendants is a cloud upon complainant’s title.
The bill prayed for discovery of the names of persons to whom Eugene C. Hall and Charles A. Elsy have assigned interests in the patent; that the license contract be set aside; that defendants be decreed to reassign the patent to complainant; that they be decreed to pay her sums of money lost by reason of their wrongful acts; that they be restrained from making any assignments of said patent and from advertising a right in them to manufacture or sell packing materials under said patent, and, lastly, for the appointment of a receiver to take an assignment of the patent.
It is insisted for the defendants that the trial court had no jurisdiction to enjoin the infringement of letters patent or to assess damages for their infringement. Hollida v. Hunt, 70 Ill. 109. This question is not in the case. The bill does not seek, as we read it, to enjoin the infringement of the patent or to assess any damages therefor. The purpose of the bill seems to be to restrain the defendants from wrongfully asserting any rights whatsoever under the so-called license contract. The bill on its face alleges that the original grantees, Eugene C. Hall and Charles A. Elsy, had failed to comply with the terms of the contract and complainant seeks to exercise a right to terminate the contract in accordance with its express terms, as shown by paragraph 5 above quoted.
*118 No question is presented by tbe bill as to tbe validity of tbe patent, nor is it charged that either or any of -the defendants named bad in any way infringed upon tbe rights granted thereunder. Tbe damages sought under tbe bill are not for any alleged infringement of tbe patent, but for a violation of tbe terms of tbe contract, and complainant seeks by her bill a forfeiture of tbe contract under which tbe defendants, as alleged, assumed to exercise and bold certain rights and privileges.
Tbe bill charges that tbe complainant bad given notice, as required by tbe contract, of her election to terminate tbe license contract, and if tbe charges made in her bill be true, she bad an undoubted right to appeal to a State court of equity to declare a forfeiture thereof and of any rights claimed by tbe defendants thereunder.
Tn tbe case of Standard Dental Mfg. Co. v. National Tooth Co., 95 Fed. 291, it was sought to. forfeit a contract in main particulars like tbe one in tbe present case. One of tbe grounds of defense was that tbe federal court bad no jurisdiction to grant tbe relief prayed for. In deciding tbe case the federal court said:
“Tbe obvious and logical course for tbe complainant in this case would be either to sue for damages for tbe nonpayment of royalties, or, by a bill in equity, seek tbe rescission of tbe contract of license, and, that being obtained, to pursue tbe defendant in a federal court for an infringement; but in tbe case at bar tbe complainant seeks a rescission of tbe contract and a remedy for infringement in tbe same bill. The jurisdiction of this court, as we have already said, can only attach, if it attach at all, by reason of tbe provisions of the patent law of tbe United States, which specially confers jurisdiction in cases arising under it. But in this case tbe complainant, in its bill, sets up a license, which, prima facie, protects the defendant in regard to tbe acts complained of, but which complainant says *119has been forfeited by the nonperformance by defendant of its stipulated payment of royalty, and for which it asks this court to order the said contract of license to be delivered np and canceled. No suit for infringement can therefore lie until after this matter -of the forfeiture is determined. This becomes and is the principal subject-matter of the present suit, and of that, as we have already shown, this court has no jurisdiction. The Supreme Court has so distinctly supported this view in the cases of Wilson v. Sandford, 10 How. 99, and Hartell v. Tilghman, 99 U. S. 547, that they must be considered as controlling the decision of the question here discussed.”
And so here, it is our opinion that the principal matter of the present suit is the prayer for a rescission of the license contract and the determination of the rights of defendants and complainant thereunder.
In the case of Hartell v. Tilghman, 99 U. S. 547, it was sought to rescind a contract by decree of court. The parties to the suit were citizens of the same State, and in deciding the case the court said:
“Such a case is not cognizable in a court of the United States by reason of its subject-matter, and as the parties could not sustain such a suit in the circuit court by reason of citizenship, this bill should have been dismissed.”
The cases cited in the brief of counsel for complainant sustain the position taken that the trial court had jurisdiction to grant the principal relief sought by the bill. No question is presented by the bill as to the validity of the patent. The only inquiry thereunder is as to what rights the parties acquired under the license contract, and the complainant properly sought the aid of the State court in determining these rights. The defendant Rogers’ Journal Packing Company is not made a party to the suit on the theory that it had infringed, or threatened to infringe, upon the rights granted by the patent. Its presence in the case is accounted for because it is sought to charge it as assignee *120of Eugene C. Hall and Charles A. Elsy. Under the hill the trial court, as to the company, could only determine whether it had assumed to exercise any rights or privileges granted to the original licensees. The fact that complainant has asserted that neither the original licensees nor the other defendants had any subsisting rights under the license contract after service of notice as required thereby is not in and of itself sufficient to deprive the trial court of jurisdiction to grant the principal relief prayed for.
The order of the superior court will be affirmed.
Affirmed.
