OPINION OF THE COURT
This matter is before the court on an appeal from an order of the district court dated September 30, 1999, denying American Cardiovascular Systems’ (“ACS”) motion for a stay of patent infringement litigation pending arbitration pursuant to 9 U.S.C. § 3. ACS sought a stay in this litigation brought by Medtronic/Arterial Vascular Engineering, 1 Inc. (“AVE”) so that it could enforce the arbitration clauses in two agreements containing a release and a covenant not to sue, respectively, into which ACS had entered with C.R. Bard, Inc. (“Bard”). After ACS and Bard executed these agreements, AVE, in 1998, purchased Bard’s coronary catheter business. At that time Bard assigned the two agreements to AVE. AVE and ACS agree that the arbitration clauses are valid and that them provisions bind them, but AVE asserts that the claims it advances in this patent infringement litigation are outside the scope of the two agreements. The district court agreed with AVE and ACS appeals. We will affirm the district court’s order denying the motion to stay the litigation pending arbitration because Bard never owned the claims involved in this litigation and, as a result, disputes regarding them are not subject to the arbitration provisions of either agreement. Thus, although AVE has stepped into Bard’s shoes, inasmuch as it owes to ACS only obligations it derived from Bard, the arbitration clauses in the two agreements do not apply to AVE’s separate claims involved here.
I. BACKGROUND
ACS’s coronary stent delivery systems consist of small pieces of stainless steel that are laser cut from a tube and affixed to a stent delivery catheter. The FDA-approved coronary stent is pre-mounted on a catheter that positions the stent in the appropriate region of the blood vessel. The balloon end of the catheter is inflated to expand the stent and place it against the vessel wall. The catheter then is withdrawn.
(a) The 1992 Agreement
Bard, a company involved in the development, manufacture and sale of medical devices, sued ACS in 1988, alleging infringement of certain of its patents for catheter technology.
See C.R. Bard, Inc. v. Advanced Cardiovascular Sys., Inc.,
No. SA CV 88-646 JSL,
*49 The 1992 Agreement contained mutual releases which provided that each party:
on behalf of [itself and its] respective prеdecessors, successors, parents, subsidiaries, assigns, stockholders, officers, directors, attorneys, agents, employees and representatives hereby releases and discharges the other party, and its respective predecessors and successors, parents, subsidiaries and their respective assigns, stockholders, officers ... from any and all debts, claims, demands, damages, liabilities, obligations, causes of action, agreements, suits, sums of money, and rights, whether known or unknown, suspected or unsuspected, which are based on any actions or inaction occurring prior to the date of this Agreement and which the party now owns or holds, or at any time heretofore owned or held, by reason of any act, matter, cause or thing whatsoever [subject to certain exceptions not relevant here].
1992 Agreement ¶ 8; app. at 87-88.
The agreemеnt also provided for arbitration to settle certain disputes:
Any dispute between the parties concerning the construction, interpretation, and effect of this Agreement or any clause herein contained, or the rights and liabilities of the parties hereunder, or the coverage of any patent claims licensed herein, shall be resolved, if necessary, by binding arbitration in accordance with the commercial arbitration rules of the American Arbitration Association, and judgment upon the award rendered by the arbitrator(s) may be entered in any court having jurisdiction thereof.
1992 Agreement ¶ 15.a; app. at 92.
(b) The 1998 Agreement
In 1997 Bard sued ACS for infringement of certain of its patents for catheters based on actions not covered by the 1992 Agreement.
See C.R. Bard, Inc. v. Advanced Cardiovascular Sys., Inc.,
Bard and its Affiliates covenant not to sue ACS and its Affiliates for any and all debts, claims, demands, and liabilities, whether known or unknown, suspected or unsuspected, which are based in any way on any and all of ACS’s and its Affiliates past and current domestic and foreign angioplasty catheters including stent delivery catheters. For purposes of this section, “ACS’s and its Affiliates past and current domestic and foreign angioplasty catheters including stent delivery catheters” shall mean ACS’s and its Affiliates past and current domestic and fоreign angioplasty catheters including stent delivery catheters and shall specifically exclude any future modifications to such products.
1998 Agreement ¶ 4.b; app. at 110.
The 1998 Agreement required ACS to deliver to Bard certain catalogues and materials which showed “current domestic and foreign angioplasty catheters including stent delivery catheters” to identify products exempted from suit by the Agreement. See app. at 110 (1998 Agreement ¶ 4.b). The ACS Coronary Stent Delivery *50 Systems, including the ACS RX Multi-Link and the ACS RX Multi-Link HP, were listed and pictured in the materials that ACS provided to Bard, and these products were the subject of the infringement action. See app. at 56-57. The U.S. and International Product Brochures ACS delivered listed the integrated stent delivery systems which consist of a stent mounted on a stent delivery catheter. See app. at 20-38.
In this 1998 Agreement, Bard and ACS also agreed to settle certain disputes by arbitration as provided in the following clause:
Any dispute between the parties concerning the construction, interpretation, and effect of this Agreement or any clause herein contained, or the rights and liabilities of the parties hereunder, or the coverage of any patent claims licensed herein, shall be resolved, if necessary, by binding arbitration in accordance with the commercial arbitration rules of the American Arbitration Association, and judgment upon the award rendered by the arbitrator(s) may be entered in any court having jurisdiction thereof.
1998 Agreement ¶ 13; app. at 116.
(c) Actions Between ACS and AVE and AVE’s Purchase of Bard’s Business
During the period of its disputes with Bard, ACS also was involved in litigation with AVE. ACS first sued AVE in December 1997 in the Northern District of California, and AVE sued ACS on February 18, 1998, in the District of Delaware. AVE’s complaint for patent infringement of its stent technology patents against ACS involves two ACS corоnary stent delivery systems: the ACS RX Multi-link Stent Delivery System and the ACS RX Multi-link HP Stent Delivery System. AVE also has advanced various state law claims against ACS (including breach of contract, misappropriation of trade secrets, unfair competition, and wrongful acquisition of property and conversion) regarding the development of the stent delivery systems and events that occurred between 1989 and 1991. Then, in April 1998, ACS brought a second patent infringement action in the Northern District of California against AVE.
While these three actions were pending, on October 1, 1998, AVE purchased the assets of Bard’s coronary catheter business which included its various catheter technology patents. See app. at 176. The 1992 Agreement allowed its assignment as long as the patents that were the subject of the Agreement were transferred, see app. at 95-96 (1992 Agreement ¶ 22), and the 1998 Agreement allowed its assignment in connection with a merger, consolidation or sale of its stock or sale of the assets of its business. See app. at 119-20 (1998 Agreement ¶ 20). Accordingly, Bard assigned all of its rights and obligations under the two agreements to AVE.
On February 8, 1999, in response to AVE’s action against it and after the California court transferred the two cases pending before it to Delaware, ACS moved to stay AVE’s district court action, Medtronic AVE, Inc. v. Advanced Cardiovascular Sys., Inc., No. 98-80-SLR (D.Del), pending arbitration of whether either the release in the 1992 Agreement or the covenant not to sue in the 1998 Agreement bars the action. In addition, ACS filed a demand for arbitration. Obviously, the demand for arbitration was somewhat unusual as ACS predicated it on provisions in agreements to which AVE was not a party when it brought the action. AVE opposed ACS’s motion, arguing that Bard never owned AVE’s claims against ACS for infringement of AVE’s stent patents or the state law claims involved in the litigation *51 between AVE and ACS. AVE also argued that the Bard-ACS agreements did not cover these claims and that they were not subject to arbitration.
In March 1999, the district court held a hearing on ACS’s motion and then, on September 30, 1999, denied the motion. See app. at 5 (Mem. Order at 1). The district court held that it could not interpret the release of all claims held by Bard in the 1992 Agreement or its undertakings in the 1998 Agreement as applying to separate claims held by Bard’s assignee, AVE. See app. at 16 (Mem. Order at 12). The court stated that “[although catheters and stents may be bundled for marketing purposes, there can be no question but that catheters and stents involve different technology and patents and that AVE developed its stent technology independent of Bard [the assignor to AVE].” App. at 17 (Mem. Order at 13).
• Subsequently, ACS made a motion to reargue its motion to stay the action pending arbitration or, in the alternative, for a stay pending appeal. On March 24, 2000, ACS withdrew its motion to reargue and filed an appeal from the district court’s September 30, 1999 order. On March 31, 2000, ACS moved in this court to stay proceedings in the district court pending appeal, and, after AVE filed its opposition to ACS’s motion, a motions panel of this court referred ACS’s motion to the merits panel by an order dated May 5, 2000. ACS, however, has withdrawn the motion as the district court has stayed the proceedings before it.
(d) Related Cases and Proceedings
This case,
Medtronic AVE, Inc. v. Advanced Cardiovascular Systems, Inc.,
98-80-SLR, has been consolidated with the two proceedings ACS brought against AVE in the Northern District of California and which the California court transferred to the District of Delaware,
Advanced Cardiovascular Systems, Inc. v. Arterial Vascular Engineering, Inc.,
No. 98-314, and
Advanced Cardiovascular Systems, Inc. v. Arterial Vascular Engineering, Inc.,
No. 98-316. Medtronic, Inc., AVE’s parent company, also has sued ACS twice regarding infringement of Medtronic’s stent patents.
See Medtronic, Inc. v. Advanced Cardiovascular Sys., Inc.,
No. 97-2459 JMR/FLN (D.Minn.);
Medtronic, Inc. v. Advanced Cardiovascular Sys., Inc. and Guidant Corp.,
No. 99-761 JMR/FLN (D.Minn.). ACS moved to stay the proceedings based on the arbitration clause in the 1998 Agreement between Bard and ACS. The district court denied ACS’s motion, and the Court of Appeals for the Eighth Circuit affirmed.

II. DISCUSSION
(a) Jurisdiction
The district court had jurisdiction over this patent infringement case pursuant to 28 U.S.C. § 1331 and 1338(a). We conclude for the reasons we set forth that we have jurisdiction over the appeal of the denial of the motion to stay pending arbitration pursuant to 9 U.S.C. § 16(a)(1)(A) and 28 U.S.C. § 1294(1).
The parties in their primary briefs indicated, without substantial discussion, that this court has jurisdiction over this аppeal under 9 U.S.C. § 16(a)(1)(A). We, however, questioned this point inasmuch as the district court’s jurisdiction was based in whole or in part on 28 U.S.C. § 1338 so that under 28 U.S.C. § 1295(a) the United States Court of Appeals for the Federal *52 Circuit would have exclusive jurisdiction over an appeal from a “final decision” in this case. Accordingly, we directed the parties to file supplemental briefs on the jurisdictional point. In their supplemental briefs they have adhered to their position that we have jurisdiction.
After considering these briefs we have determined that we have jurisdiction and thus we adjudicate this appeal on the merits. Our starting point is 9 U.S.C. § 16(a)(1)(A) which makes the order in this case appealable. Section 16(a)(1)(A), however, does not indicate the court to which such an appeal may be taken. Thus, we examine the general statutes providing for the courts of appeals’ jurisdiction. We conclude that section 1296(a) does not vest jurisdiction in the Court of Appeals for the Federal Circuit because this appeal is not from a “final decision.” After all, rather than ending the litigation on the merits,
see John Hancock Mutual Life Ins. Co. v. Olick,
We also conclude that the Court of Appeals for the Federal Circuit could not have jurisdiction over this appeal under 28 U.S.C. § 1292(с) which vests it with exclusive jurisdiction over an appeal from an interlocutory order as described in 28 U.S.C. § 1292(a)(1) or (b) in cases in which it would have jurisdiction over an appeal from a final decision under section 1295. Plainly section 1292(b) cannot be applicable as the procedures for allowing an interlocutory appeal as set forth in that section have not been followed here.
Thus, we are left to consider only section 1292(a)(1) which deals,
inter alia,
and as possibly applicable here, with orders refusing to grant injunctions. Upon consideration of that subsection we are satisfied, in harmony with
Gulfstream,
In view of the foregoing analysis we come to the сonclusion that the Court of Appeals for the Federal Circuit would not have had jurisdiction if ACS had prosecuted this appeal to that court. That conclusion, however, in itself does not mean that we do have jurisdiction. After all, what we have held with respect to the Court of Appeals for the Federal Circuit’s lack of jurisdiction under section 1295(a) would apply equally to us if we attempted to exercise jurisdiction under our usual source of jurisdiction, 28 U.S.C. § 1291, as that section, like section 1295(a), provides for jurisdiction only over appeals from “final decisions.” Moreover, we no more can *53 exercise jurisdiction under section 1292(a)(1) by regarding the order denying the stay as an order denying an interlocutory injunction than could the Court of Appeals for the Federal Circuit under section 1292(c)(1) which incorporates that section. Thus, this cаse is the unusual one that finally turns on the residual jurisdictional statute, 28 U.S.C. § 1294(1), which provides, with exceptions that we hold are inapplicable, that an appeal from a reviewable decision of a district court “shall be taken to the ... court of appeals for the circuit embracing the district.” Inasmuch as the appeal has been taken from the United States District Court for the District of Delaware, which is within this circuit, we have jurisdiction.
In reaching our result we have not overlooked the opinion of the Court of Appeals for the Seventh Circuit in
In re BBC International, Ltd.,
Here, however, our methodology is different as we are deciding the case on the basis of what court has jurisdiction now. Thus, our analysis in no way is confined by a provision such as that in section 1651(a) that a court may issue writs “in aid” of its jurisdiction. Consequently, the circumstance that the Court of Appeals for the Federal Circuit will have exclusive jurisdiction over any appeal from a final decision in this case does not require that we conclude differently than we do with respect to our jurisdiction over the appeal in this case at this time.
(b) Standard of Review
We exercise plenary review over the legal questions concerning the applicability and scope of an arbitration agreement.
See Harris v. Green Tree Fin. Corp.,
(c) Court Decides Arbitrability of Dispute
When Congress enacted the Federal Arbitration Act, 9 U.S.C. §§ 1-13, it provided a framework for the development оf a body of uniform federal law governing contracts within its scope. Therefore, if the Arbitration Act is applicable, federal law applies in questions regarding the construction and enforcement of an arbitration clause, even in those cases in which the district court’s jurisdiction is based on diversity of citizenship.

See Mitsubishi Motors Corp. v. Soler Chrysler-Plymouth, Inc.,
In appropriate circumstances, 9 U.S.C. § 4 allows litigants to obtain an order requiring a reluctant party to arbitrate a dispute, as it directs the district court to order a party to arbitrate if it is “satisfied that the making of the agreement for arbitration or the failure to comply therewith is not an issue.”
PaineWebber Inc. v. Hartmann,
While a court asked to stay proceedings pending arbitration must de
*55
termine whether there is a valid agreement to arbitrate and, if so, whether the specific dispute falls within the substantive scope of that agreement, “its function [nevertheless] is very limited when the parties have agreed to submit all questions of contract interpretation to the arbitrator. It is confined to ascertaining whether the party seeking arbitration is making a claim which on its face is governed by the contract.”
United Steelworkers of Am. v. American Mfg. Co.,
However, federal policy favors arbitration and thus a court resolves doubts about the scope of аn arbitration agreement in favor of arbitration.
See Moses H. Cone,
(d) The 1992 Settlement Agreement and Release
As we have indicated, AVE does not dispute that it is bound by the agreements between ACS and Bard, including the arbitration clauses. Accordingly, the question for us to determine is whether the district court erred in holding that the dispute is not within the scope of the arbitration clauses. In the release 4 contained in the 1992 Agreement, each *56 party released the other party from demands, damages, liabilities, obligations, causes of action, agreements, suits, sums of money and rights, which were based on any actions or inaction occurring prior to the date of the agreement and which the party then owned or held. See app. at 87-88 (1992 Agreement ¶ 8). The agreement also provided for arbitration of “any dispute between the parties concerning the construction, interpretation and effect of this Agreement or any clause herein contained, or the rights and liabilities of the parties hereunder.” Apр. at 92 (1992 Agreement ¶ 15.a).
But even if AVE predicates its claims on property interests extant prior to the date of the 1992 Agreement, inasmuch as Bard did not then own or hold the interests of AVE, Bard could not have agreed to release ACS from or arbitrate claims relating to those interests. Accordingly, while it is true that when AVE accepted the assignment of the 1992 agreement from Bard it “step[ped] into [Bard’s] shoes,”
see Premier Dental Prod. Co. v. Darby Dental Supply Co.,
ACS argues that
Svedala Industries,
The release agreement provided that the parties on behalf of themselves and their respective:
predecessors, successors, heirs, assigns, ... subsidiaries, sister companies, parent companies and all persons, connected with them fully release and discharge the other and their respective predecessors, successors ... subsidiaries, sister companies, parent companies ... from any and all claims, demands, causes of action, obligations, damages and liabilities of any nature whatsoever, whether or not now known, suspected or claimed....
Id. at *1. About one year later in 1994 Tidco acquired Barmac. See id. at *2. Then in 1996, Tidco assigned the '571 patent Barmac previously owned to Svedala Inc. See id. at *2. Svedala Inc. then brought a lawsuit against Kemper and Rock Engineered for infringement of the '571 patent. Kemper and Rock Engineered moved to stay the proceedings and to compel arbitration. See id. at *2.
*57 The court rejected Svedala’s argument that Svedala predicated on a contention that at the time of the 1993 release agreement it had no rights in the '571 patent and therefore had no patent infringement claim to release so that the matter did not fall within the arbitration clause. In rejecting the argument, the court reasoned, inter alia, that although Svedala Inc. did not have rights in the patent at the time of the release, Barmac did have rights in the patent at that time, and Tidco is the successor of Barmac 5 and is a sister company to the plaintiff Svedala Inc. See id. at *4. The release specified that it applied to all successors and sister companies and all persons connected with them, and Svedala Inc., in addition to being a party to the release, was a sister company of Tidco (a party to the release) and also later an assign. See id. at *1.
Obviously the situation in Svedala is completely distinguishable from that here. First of all, the plaintiff Svedala Inc. itself was a party to the broad 1993 release, whereas AVE was not a party to the 1992 release between Bard and ACS. Second, even if Svedala had not been a party to the release, Tidco was a party to the release and entered into it on behalf of its sister companies, of which Svedala was one. In this case, AVE was not bound to the release agreement between Bard and ACS through a relationship with either of the parties existing at the time of the execution of the release. Because the defendants in Svedala put forth evidence that they had made and offered for sale the accused infringing device prior to the time of the release, the fact that Svedala Inc. was a party to the release is relevant, even if the claim was unknown.
In contrast, in this case, although Bard was a party to the release and later assigned the contract to AVE, at the time of the release Bard did not own and, in fact, never owned the patents that are now the subject of the suit between AVE and ACS. This is a crucial difference because here, unlike in Svedala, the party seeking to invoke the arbitration clause is trying to apply the clause in an action on a patent that was not acquired from a party to the agreement to arbitrate. Thus, if AVE’s action against ACS concerned patents that Bard acquired after the date of the release and Bard assigned the contract containing that release to AVE, this casе would be in a very different posture.
In another case that ACS cites to support its case,
Universal Studios Inc. v. Viacom Inc.,
Universal Studios is different from this case in that the parties there were involved in a joint venture and had signed a non-compete agreement and exclusivity agreement, and the purchаser of the interest of one joint venturer stepped into its shoes thereby becoming as subject to the non-compete provision of the joint venture agreement as to all its other provisions. Accordingly, the joint venture agreement *58 and the non-compete and exclusivity agreements gave rise to different fiduciary and contractual obligations and duties than those provided by a release or covenant not to sue which relate to obligations and claims of the parties subject to the agreement rather than claims of a third party. Thus, Universal Studios dealt with the obligations of a party to adhere to the terms of a joint venture when it acquired an interest in the venture. Accordingly, the factual pattern in Universal Studios is so distinct from that here that the case is not useful in resolving the controversy here.
Reid v. Contel Cellular of Louisville, Inc.,
Subsequently Reid left McCaw Cellular’s employment and at that time received a severance package pursuant to which she released McCaw Cellular and its successors and assigns from all possible claims. Contel then successfully moved for summary judgment on the ground that it was a “successor/assign” of McCaw Cellular. On appeal, the court of appeals reversed, indicating that “Contel’s assignee status vis-a-vis McCaw extends only to the subject matter contained within the purchasе agreement and that it is illogical to allow Contel to benefit as assignee from every release to which McCaw has been a party since the date of the purchase agreement.” Id. at *2.
We certainly agree with Reid because a contrary holding would have meant that the successor to a release could apply it to bar claims quite beyond anything the parties to the release could have contemplated. After all, a releasor giving a release to a second party hardly would anticipate that, as a result of an assignment, a third party could apply the release to a claim the releasor had against the third party that was quite independent of its claims against the second party. Reid, then, supports the result the district court reached in this case.
Moreover, a release usually will not be construed to bar а claim which had not accrued at the date of its execution or a claim which was not known to the party giving the release.
See Three Rivers Motors Co. v. Ford Motor Co.,
(e) The 1998 Settlement and Covenant Not to Sue
The covenant not to sue in the 1998 Agreement provided:
*59 Bard and its Affiliates covenant not to sue ACS and its Affiliates for any and all debts, claims, demands, and liabilities, whether known or unknown, suspected or unsuspected, which are based in any way on any and all of ACS’s and its Affiliates past and current domestic and foreign angioplasty catheters including stent delivery catheters. For purposes of this section, “ACS’s and its Affiliates past and current domestic and foreign angioplasty catheters including stent delivery catheters” shall mean ACS’s and its Affiliates past and current domestic and foreign angioplasty catheters including stent delivery catheters and shall specifically exclude any future modifications to such products.
1998 Agreement ¶ 4.b; app. at 110. However, the covenant not to sue does not apply to AVE’s separate claims that Bard never owned.
In
Spindelfabrik Suessen-Schurr Stahlecker & Grill v. Schubert & Salzer Maschinenfabrik Aktiengesellschaft,
The court rejected Schubert’s argument for an implied license. Id. at 1080. Under the agreements at issue, Suessen had not made a promise not to sue under Suessen’s separate patents, and treating it as such would be an overly broad interpretation. See id. at 1081. “[A] patent license agreement is in essence nothing more than a promise by the licensor not to sue the licensee.... Indeed, the patentee of X and his licensee, when making, using, or selling X, can be subject to suit under other patents.” Id.
Similarly, in
ZapatA Industries Inc. v. W.R. Grace & Co.,
ZapatA claimed but Grace denied that ZapatA had an “implied license” under the Grace patents because Grace assumed AOTI’s warranty of non-infringement under the AOTI ZapatA settlement agreement. See id. at 1625. Consequently, ZapatA instituted an action seeking a declaration that Grace was precluded from enforcing its patents against ZapatA by reason of implied license and estoppel. Grace filed a motion for summary judgment on this issue because AOTI never owned the Grace patents or had any rights under those patents and therefore did not have any right under them to provide to ZapatA through the AOTI-Za-patA agreements. See id. The court stated: “ZaрatA received nothing more from AOTI than a promise not to be sued by AOTI on AOTI’s patents. That promise did not, and ... could not, apply to Grace’s patents which AOTI never owned and never had any rights under. To the extent Grace assumed the license, it owed ZapatA nothing more than what AOTI had owed.... Grace’s ‘commitment’ does not include a promise, express or implied, not to sue under Grace’s own patents.” Id. at 1626-27.
While obviously
Schubert
and
ZapatA
involve facts distinct from those here, similar principles apply in this case. At the time of the 1998 Agreement, Bard and ACS contracted for a covenant not to sue. When AVE stepped into Bard’s shoes, it had to adhere to the covenant not to sue on
Bard’s
claims. But absent a provision stating otherwise, assignment of a contract will result in the assignee stepping into the shoes of the assignor with regard to the rights that the assignor held and not in an expansion of those rights to include those held by the assignee. “An assignment does not modify the terms of the underlying contract. It is a separate agreement between the assignor and the assignee which merely transfers the assignor’s contract rights, leaving them in full force and effect as to the party charged.... Insofar as an assignment touches on the obligations of the other party to the underlying contract, the as-signee simply moves into the shoes of the assignor.”
Citibank, N.A v. Tele/Resources, Inc.,
ACS argues that if Bard had acquired a new patent thе day after the 1998 Agreement was executed, the agreement by its terms would have prevented Bard from asserting that new patent against the ACS products because the covenant not to sue is product based, not patent based. ACS maintains that the district court focused on the technology and the patents rather than the products. 6 See Br. of Appellant 23. *61 But the “stepping into the shoes” assignment means that even if Bard had obtained a new patent related to catheters the day after the Agreement was executed, AVE could not now sue ACS based on that patent if the covenant not to sue was interpreted to cover a patent that was obtained after the covenant not to sue was signed. 7 However, if AVE had acquired a new patent the day after the parties executed the 1998 Agreement, it still could sue on it because Bard never would have owned that patent and therefore the patent would not have been within the scope of the agreement.
III. CONCLUSION
For the foregoing reasons, we will affirm the district court’s order denying ACS’s motion to stay the proceedings in the district court pending arbitration.
Notes
. Medtronic, Inc. acquired AVE in January-1999 and thus AVE has been known as Med-tronic AVE, Inc. since that time. The district court, by an order dated October 22, 1999, allowed the caption of the consolidated cases to be amended to reflect the name change.
. When a district court interprets language contained in contracts we review its determination under the clearly erroneous standard.
See John F. Harkins Co. v. Waldinger Corp.,
. Although the Arbitration Act creates federal substantive law regarding agreements to arbitrate, it does not create any independent federal-question jurisdiction under 28 U.S.C. § 1331. 9 U.S.C. § 4 "provides for an order compelling arbitration only when the federal district court would have jurisdiction over a suit on the underlying dispute; hence, there must be diversity of citizenship or some other independent basis for federal jurisdiction before the оrder can issue.... Section 3 likewise limits the federal courts to the extent that a federal court cannot stay a suit pending before it unless there is such a suit in existence."
Moses H. Cone Memorial Hosp. v. Mercury Constr. Corp.,
. A release is a provision that intends a present abandonment of a known right or claim. By contrast, “a covenant not to sue also applies to future claims and constitutes an agreement to exercise forbearance from asserting any claim which either exists or which may accrue....”
McMahan & Co. v. Bass,
. We also note that the district court in
Sveda-la
apparently regarded Barmac as a predecessor of Tidco for purposes of the release.
See Svedala,
. The district court reasoned that there "can be no question but that catheters and stents *61 involve different technology and patents and that AVE developed its stent technology independent of Bard. The plain and unambiguous language of the 1998 Agreеment, therefore, demonstrates that the litigation at issue, involving stent technology, is not an arbitrable grievance under the 1998 Agreement.” App. at 17 (Mem. Order at 13).
. It is uncertain whether the covenant not to sue would be interpreted to cover a patent that was obtained after the covenant not to sue was signed inasmuch as the covenant covers claims that are based on ACS's and its Affiliates past and current domestic and foreign angioplasty catheters including stent delivery catheters, specifically excluding any future modifications to such products. Therefore, it is possible that a patent obtained after this agreement still would be based on a "past or current” catheter; however, it is also possible that a patent obtained after the agreement would not be considered based on such a catheter and could, for example, be considered a "future modification.”
