The Defendants-Appellants seek to appeal an interlocutory order of the District Court granting a request for an injunction. We dismiss for lack of jurisdiction.
I. BACKGROUND
Pimentel & Sons Guitar Makers, Inc. (“Guitar Makers”) is a family business that produces and sells handcrafted instruments. Lorenzo Pimentel and his two sons, Roberto and Ricardo Pimentel, operate the business. Guitar Makers has owned the federally registered trademark “PIMENTEL” since 1963. Hector Pimen-tel, also the son of Lorenzo Pimentel, is a professional guitarist and guitar instructor. In 1987, Hector began to manufacture, sell, and repair guitars.
In 1988, Lorenzo Pimentel & Sons Limited Partnership (Guitar Makers’ predecessor) filed a complaint against Hector for use of the business name, trade name, and trademark “PIMENTEL” (the “1988 litigation”). The parties to that litigation entered into a settlement resulting in an injunctive order and judgment from the Federal District Court for the District of New Mexico on September 26, 1989 (the “1989 injunction”). Among other things, the order required Hector to use a disclaimer in conjunction with his use of the name “Pimentel” in certain situations. The injunction is still in place today.
In 1994, Danette Pimentel 1 began working with Hector to promote and sell his goods and entertainment services. Dan-ette registered the corporation “Danette I. Lovato-Pimentel Music Enterprises, Inc.” with the State of New Mexico. Danette conducts business on behalf of Hector, who contracts with her as a “musician and artist.” Danette and her corporation used the name Pimentel in several ways to promote Hector.
In April 2004, Guitar Makers filed suit against Hector, Danette, and Danette I. Lovato-Pimentel Music Enterprises, Inc. for alleged violations of the 1989 injunction, the federal Lanham Act, and the New Mexico Unfair Practices Act. Guitar Makers filed a motion for a preliminary injunction requesting that the District Court enjoin the alleged violations. The District Court issued a preliminary injunction based solely on the 1989 injunction, finding that the injunction required Hector to use a disclaimer whenever he used the word “Pimentel” in a business name and that Hector had used the name several times in the preceding years without doing so. The District Court also enjoined Danette and Danette I. Lovato-Pimentel Music Enterprises, Inc. from further violations of the 1989 injunction after finding that they promoted Hector’s goods and services under trade names containing the word “Pimen-tel” without using the disclaimer. The Defendants appealed. Subsequently, Hector and Guitar Makers entered into a settlement agreement, and the District Court entered an order dismissing the suit against Hector with prejudice. Neither Danette nor her company has settled with Guitar Makers, but the District Court has *1153 dismissed all but the Lanham Act claim against them.
II. DISCUSSION
As a general rule, only final decisions of the district court are appealable. 28 U.S.C. § 1291. Section 1292(a)(1) sets forth an exception to the general rule for interlocutory orders “granting, continuing, modifying, refusing or dissolving injunctions, or refusing to dissolve or modify injunctions.” 28 U.S.C. § 1292(a)(1). We have noted that “an interlocutory order expressly granting or denying injunctive relief fits squarely within the plain language of section 1292(a)(1).”
Tri-State Generation & Transmission Assoc. v. Shoshone River Power, Inc.,
Section 1292(a) was intended to carve out only a limited exception to the final-judgment rule of 28 U.S.C. § 1291 and the “long-established policy against piecemeal appeals.”
Gardner v. Westinghouse Broad. Co.,
Due to this narrow construction mandate, courts of appeals insist on looking beyond the captions and vocabulary attached to district court orders to determine the actual, practical effect of an order before exercising appellate jurisdiction under § 1292(a)(1).
See, e.g., Birmingham Fire Fighters Ass’n 117 v. Jefferson County,
In short, in deciding whether a district court order “granting” an injunction is appealable under § 1292(a)(1), we consider the substance rather than the form of the motion and caption of the order.
*1154
See Sierra Club v. Marsh,
Because the District Court’s order here was based solely on its interpretation of the 1989 permanent injunction, the proper question is whether the court’s order actually modified the existing injunction or instead, as in
Gautreaux,
merely clarified or interpreted the prior injunction. Appellate courts do not have jurisdiction to review a district court order that merely interprets or clarifies, without modifying, an existing injunction.
See, e.g., Motorola, Inc.,
Danette argues that the District Court modified the 1989 injunction because (1) it grossly misinterpreted the injunction and (2) it extended its application to Danette and her corporation, even though they were not parties to the 1988 litigation and were not named in the 1989 injunction. We reject both arguments.
Whether an order interprets or modifies an injunction is determined by its actual, practical effect.
See Carson,
The District Court rejected Dan-ette’s argument that Hector only has to use the disclaimer when “Pimentel” is used in conjunction with his guitar-making business. Instead, the court concluded that the 1989 injunction requires Hector to use the disclaimer every time he uses the name “Pimentel” in a business name. This conclusion is a straightforward interpretation of the injunction’s plain language. As such, it does not create appellate jurisdiction by modifying the underlying injunction. Danette’s contention that the District Court disregarded the parties’ original intent behind the 1989 injunction and therefore misinterpreted the plain language of the injunction is beyond the scope of this interlocutory appeal. As the Eleventh Circuit has explained, “[i]n attempting to discern in
*1155
terpretation from modification, ... we should not analyze the injunction and the order in detail. To plunge into the details would collapse the jurisdictional inquiry into a decision on the merits, thwarting the purpose of § 1292(a)(1).”
Birmingham Fire Fighters Ass’n,
Nor is the court’s application of the 1989 injunction to Danette a modification of that injunction. Under Fed.R.Civ.P. 65, every order granting an injunction is binding upon “the parties to the action, their officers, agents, servants, employees, and attorneys, and upon those persons in active concert or participation with them who receive actual notice of the order by personal service or otherwise.” Fed.R.Civ.P. 65(d);
see also Int’l Bhd. of Teamsters, Local 523 v. Keystone Freight Lines, Inc.,
The District Court did not therefore issue an “injunction” at all, but simply interpreted or clarified the existing injunction. As a result, this action is not appealable under § 1292(a)(1).
III. CONCLUSION
For the foregoing reasons, we DISMISS the appeal for lack of jurisdiction. We also DENY Guitar Makers’ motion for costs and attorneys’ fees associated with this appeal. Both motions filed by counsel Jerry Walz and Henry Narvaez, to withdraw as counsel and to substitute as counsel, are granted.
Notes
. Danette and Hector married in 1995 and divorced in 2003.
