Intermedies Infusaid, Inc., and The Infusaid Company appeal from the August 22, 1985, orders of the United States District Court for the District of Massachusetts (Tauro, J.), (1) denying Intermedies’ motion to enjoin an action between the parties in a Minnesota state court and (2) granting a motion to stay the action before the federal district court. We affirm.
I.
In May, 1973, United States Patent No. 3,731,681, issued to a group of employees of the University of Minnesota, with the University named as assignee. The patent discloses and claims an implantable drug infusion pump — a device designed to be implanted in the human body for pumping drugs on a constant basis to a specific organ or location in the body.
In October, 1980, the University granted an exclusive license of the patent to Metal Bellows Corporation, who in turn granted an exclusive, royalty-free sublicense to its subsidiary, Infusaid Corporation. In January, 1981, Infusaid Corporation entered into a joint venture with an unrelated company, Intermedies Infusaid, Inc., a subsidiary of Intermedies, Inc. The purpose of the joint venture (which operates as Infusaid Company) was, in part, to develop and
The business relationship apparently soured and, in May, 1982, Infusaid Corporation and its parent, Metal Bellows, sued Intermedies (parent and subsidiary) in the United States District Court for the District of Massachusetts, seeking dissolution of the joint venture and an accounting and distribution of their interests therein (the Venture suit). During a hearing in the course of that suit, counsel for Intermedies at one point asserted that the University’s patent was worthless and moved to amend its complaint to so allege. That motion was denied. After a trial and an appeal, on September 21, 1984, the district court (Judge McNaught) issued an injunction which granted exclusive possession of the assets and control of the Venture to Intermedies. That order did not, however, terminate the suit as an accounting remained necessary.
On or about October 17, 1984, the University filed a declaratory judgment action in Minnesota state court against Metal Bellows, Infusaid Corp., Intermedies (parent and subsidiary), and the Venture seeking a declaratory judgment that the original license agreement with Metal Bellows “is valid and enforceable in all respects” against the defendants and asking the Minnesota court to determine the amount of royalties owed (the Minnesota suit). In defense of that suit, Intermedies and the Venture asserted, inter alia, a royalty-free license.
In November, 1984, Intermedies reacted to the Minnesota suit with motions in the Venture suit (then at the accounting stage) to make the University a party and to enjoin the Minnesota suit. Their argument was that the validity of the patent was germane to those proceedings. Judge McNaught denied the motions on March 20, 1985. In his order of that date, Judge McNaught observed that the only issue concerning the University’s patent was the value of the patent license at the date of dissolution of the joint venture “at which time the patent had not been declared invalid and carried a presumption of validity, whether or not it had been challenged.” Doubts of the parties with respect to validity were considered germane to the evaluation of the license, but the actual validity of the patent was held to be irrelevant.
On May 15, 1985, the Minnesota court issued an order requiring Intermedies

to “plead any additional affirmative defenses not contained in its Answer, including patent invalidity ... no later than June 12, 1985, or [Intermedies] shall be precluded from raising any such defense as an affirmative defense to this action.” Intermedies did not afford itself of that opportunity. Instead, on June 12, 1985, approximately 9 months after the Minnesota suit began and discovery was virtually complete, Intermedies filed the instant action in the Massachusetts district court against the University, seeking a declaratory judgment that the University’s patent is invalid and unenforceable and to recover royalties they had previously paid (the. Patent declaratory judgment action).

As part of the relief requested, Intermedies sought to enjoin proceedings in the Minnesota suit and filed a motion seeking that relief immediately. Two reasons were put forth for the requested injunction: (1) the Minnesota suit was an attempt by the University to circumvent the federal district court’s ex-
On August 22, 1985, the district court refused to enjoin the Minnesota suit and granted a stay of the Patent declaratory judgment action. Intermedies timely appealed to this court seeking reversal of both orders of the district court. 5
During the pendency of this appeal, summary judgment was entered for the University in the Minnesota suit with an award made in the sum of $235,245.35. Regents of the University of Minnesota v. Metal Bellows Corp., No. 84-16041 (4th D.Minn. 1986) (Durda, J.). The validity of the University’s patent is not mentioned in the opinion. Intermedies has appealed that judgment to the Minnesota appeals court.

Issues
1. Are the district court's interlocutory orders appealable?
2. Did the district court improperly decline to enjoin the state court proceedings?
3. Did the district court improperly stay its own proceedings?
III.
This case falls into the familiar pattern of a suit by the licensor of a patent in state court to secure royalties due under a license agreement and a counterattack by the licensee in federal court to have the patent declared invalid. In this federal declaratory judgment action, the licensee sought to enjoin the state court proceedings which was denied. The order of the court denying such request is a denial of an injunction and is, therefore, appealable under 28 U.S.C. § 1292(c)(1) (1982).
The Anti-Injunction Act, 28 U.S.C. § 2283 (1982 & Supp. II 1984) provides:
A court of the United States may not grant an injunction to stay proceedings in a State court except as expressly authorized by Act of Congress, or where necessary in aid of its jurisdiction, or to protect or effectuate its judgments. (Emphasis added.)
Intermedies first argues that the requested injunction of state proceedings falls within the exception, underlined above, which requires, per Intermedies, a federal court to exercise its injunctive power “in aid of its jurisdiction.” Intermedies argues that 28 U.S.C. § 1338(a) (1982), the provision giving the federal district courts “exclusive” jurisdiction over patent suits, codifies a policy that patent questions be decided in the federal courts.
While made in a different procedural context, this argument was considered and rejected by this court in
In re Oximetrix, Inc.,
In Lear v. Adkins, patent invalidity was held to be a defense which could be made by a licensee to a claim for royalties in state court. Although Intermedies was given that opportunity in the Minnesota suit by a specific order of that court, Intermedies failed to do so. The University argues that Intermedies’ failure in the Minnesota suit to raise that defense, which it could have litigated there and which the University asserts was a mandatory counterclaim, makes the issue of validity of the patent res judicata between the parties. Intermedies urges that the order of the Minnesota court was narrow and that it is precluded from asserting invalidity only in the Minnesota suit.
We do not, of course, have the issue of
res judicata
before us. At the time of the federal court order under review, the Minnesota suit had not reached judgment. Intermedies’ objective in attempting to enjoin the state suit is, however, candidly stated. It seeks to prevent the entry of a judgment which could possibly be
res judicata
of the issue of patent validity. If the state court judgment is ultimately held to subsume the issue of patent validity, Intermedies will have bypassed the opportunity it had to challenge the patent, and its tactic of not litigating the defense of invalidity in state court will turn out to have been legally disastrous.
See Marrese v. American Academy of Orthopaedic Surgeons,
Alternatively, Intermedies argues that the requested injunction should have been granted to protect and effectuate the federal court’s ability to grant relief. This argument is based on the premise that a final state court judgment would improperly force Intermedies to pay royalties which Intermedies could not recoup even if the patent were later found invalid. This court held in
Cordis Corp. v. Medtronics, Inc.,
For the above reasons, we are unpersuaded that Intermedies’ request for an injunctive order staying the Minnesota suit falls within an exception to 28 U.S.C. § 2283. 7
Before addressing the merits of the order “dismissing” the patent suit, we must first consider the University’s argument that we have no jurisdiction over that order.
The University asserts that despite the technical entry of a dismissal,
supra
note 5, the order is simply a “stay” and not a final appealable order. The cases are legion that where a court simply stays its own proceedings, generally that type of order is not appealable.
See Gould v. Control Laser Corp.,
Intermedies counters with arguments that it has been effectively placed out of court by the district court’s action and, thus, the dismissal/stay order must be treated as an appealable order under the finality principles set forth in
Moses H. Cone Memorial Hospital v. Mercury Construction Corp.,
We need not resolve this difficult issue. The dismissal/stay order in this case need not itself provide an independent jurisdictional basis for an appeal. Unquestionably this court properly has an appeal before it based on the court’s refusal to enjoin the Minnesota suit.
In connection with review of that appealable interlocutory order, other interlocutory orders, which ordinarily would be nonappealable standing alone, may be reviewed.
See, e.g., Shaffer v. Globe Protection, Inc.,
We agree with the University that the action taken by the district court was a stay, not an outright dismissal, of the proceedings before us. Thus, the court was not required to state its reasons. However, the parties have plowed the ground thoroughly.
In sum, Intermedies has failed to persuade us that the district court abused its discretion in staying its own proceedings. First, these proceedings had just been instituted, whereas, proceedings in the Minnesota suit were well advanced at the time the stays were sought. Intermed
Finally, we do not see any possibility of prejudice to Intermedies by reason of duplicative or piecemeal litigation. Either the patent validity issue will be barred or mooted by the Minnesota judgment or it will be litigated in the federal district court. In the latter event, that court may or may not have to resolve the royalties recoupment issue. Moreover, these matters could have been resolved in the Minnesota suit. If there is piecemeal litigation, Intermedies cannot complain of its burdens.
The above factors are among those considered by the Supreme Court in determining the propriety of a federal court’s abstention because of parallel proceedings in a state court in
Moses Gone, supra,
and
Colorado River Water Conservation District v. United States,
In addition, as indicated, there is also the consideration that as a result of the Minnesota action, the issues in the Patent declaratory judgment action may be either precluded or moot. The court’s abstention from exercising jurisdiction until these waters have settled seems to us extremely prudent.
For the foregoing reasons, we hold that the district court did not abuse its discretion in staying the Patent declaratory judgment action.
AFFIRMED.
Notes
. Because of the confusing names, the Infusaid Company will be identified herein simply as the Venture.
. Hereinafter, "Intermedies” refers not only to the parent and subsidiary but to the Venture as well.
. Intermedies also began escrowing royalties, rather than paying them to the University as required by the license. In so doing, they relied on
Cordis Corp. v. Medtronic, Inc.,
. Intermedies' motion stated:
Though artfully worded to sound in contract, the University’s complaint in the Minnesota state court action on its face raises questions concerning the scope and validity of the Patent. By the filing of the Minnesota state complaint, the University is attempting to obtain jurisdiction for the state court over a case that arises under the patent laws of the United States and theregy circumvent this Court’s exclusive jurisdiction over cases arising under the patent laws, pursuant to 28 United States Code, Section 1338(a). Accordingly, a stay .of the Minnesota state court action is necessary in aid of this Court’s exclusive jurisdiction over cases arising under the patent laws and is necessary to protect and effectuate this Court’s judgments.
. The order of the district court technically "dismissed” the Patent declaratory judgment action without prejudice to "either party moving to restore it to the docket” upon "final disposition” of the state court action. The court entered a "dismissal” rather than a "stay” expressly stating that a dismissal would avoid the inconvenience to the parties of answering status calls. We will refer to the action by the court as a "stay" inasmuch as whether it is a stay or a dismissal without prejudice is immaterial to our reaching the merits.
.
In
Lear v. Adkins,
the state court stayed its own proceedings on remand in deference to a federal patent declaratory judgment action.
