OPINION AND ORDER OF THE COURT
Dr. Lakshmi Arunachalam has filed a petition for a writ of mandamus seeking an order requiring the disqualification of a District Judge. We conclude that we lack jurisdiction over the petition and will direct the Clerk to transfer it to the United States Court of Appeals for the Federal Circuit.
Arunachalam is a plaintiff in a number of related patent infringement actions that are or were pending in the United States District Court for the District of Delaware. Her complaints invoke the District Court’s jurisdiction under 28 U.S.C. § 1338(a) and are premised solely on alleged patent infringement. Thus, any appeal from the final decisions in these actions must be taken to the Federal Circuit, which has exclusive jurisdiction over appeals in pat*292ent infringement actions. See 28 U.S.C. § 1295(a)(1); Christianson v. Colt Indus. Operating Corp., 486 U.S. 800, 808-09, 108 S.Ct. 2166, 100 L.Ed.2d 811 (1988). Indeed, Arunachalam already has taken one such appeal to the Federal Circuit, which dismissed it as a sanction following briefing. See Pi-Net Int’l, Inc. v. JPMorgan Chase & Co., 600 Fed.Appx. 774, 775 (Fed.Cir.2015), cert. denied, No. 15-691, — U.S.-, 136 S.Ct. 856, 193 L.Ed.2d 720, 2016 WL 100455 (U.S. Jan. 11, 2016).1
In the actions at issue here, Arunacha-lam filed motions to disqualify the District Judge on the basis of the District Judge’s ownership of mutual funds that have holdings in certain of the defendant corporations. The District Judge denied the motions by issuing the same memorandum and order in each action on March 28, 2015. Arunachalam now challenges that ruling by seeking a writ of mandamus from this Court ordering the District Judge’s disqualification.
A District Judge’s denial of a disqualification is properly reviewable by mandamus, at least when disqualification is sought under 28 U.S.C. § 455. See In re Kensington Int’l Ltd., 353 F.3d 211, 219 & n. 7 (3d Cir.2003); In re Sch. Asbestos Litig., 977 F.2d 764, 776-77 (3d Cir.1992). Our authority to issue writs of mandamus, however, extends only to situations in which doing so would be “in aid of’ our jurisdiction. 28 U.S.C. § 1651(a). “Before entertaining [an] application [for mandamus], then, we must identify a jurisdiction that the issuance of the writ might assist.” United States v. Christian, 660 F.2d 892, 894 (3d Cir.1981). As explained above, the Federal Circuit has exclusive jurisdiction over any appeals that might be taken from the final decisions in these actions. Thus, it does not appear that the actions “may at some future time come within th[is] court’s appellate jurisdiction.” Id. Because we lack appellate jurisdiction over these actions, we have no jurisdiction that issuance of the writ can be said to assist.
For this reason, the only Courts of Appeals to have addressed the issue have concluded that they lack jurisdiction to issue writs of mandamus in patent infringement actions over which the Federal Circuit has exclusive appellate jurisdiction. See Lights of Am., Inc. v. U.S. Dist. Ct., 130 F.3d 1369, 1370-71 (9th Cir.1997) (per curiam); In re BBC Int’l, Ltd., 99 F.3d 811, 813 (7th Cir.1996). Those courts concluded that, when the Federal Circuit has exclusive appellate jurisdiction, -the Federal Circuit has exclusive mandamus jurisdiction as well. See Lights of Am., 130 F.3d at 1371; In re BBC Int’l, Ltd., 99 F.3d at 813. The Federal Circuit agrees that it has exclusive mandamus jurisdiction in patent infringement actions, see In re Princo Corp., 478 F.3d 1345, 1351 (Fed.Cir.2007), and it regularly exercises that jurisdiction to entertain disqualification-based mandamus petitions like the one that Arunachalam filed here, see, e.g., In re Beyond Innovation Tech. Co., 166 Fed. Appx. 490, 491-92 (Fed.Cir.2006). Decisions by other courts in analogous contexts are in accord.2 We agree with these deci*293sions and conclude that, when the Federal Circuit has exclusive appellate jurisdiction over a patent infringement .action, it has exclusive jurisdiction over mandamus petitions arising from that action as well.
Arunaehalam argues that we have jurisdiction over her petition pursuant to the residual jurisdictional statute, which provides in relevant part that, “[ejxcept as provided in section[ ] ... 1295 of this title, appeals from reviewable decisions of the district ... courts shall be taken ... to the court of appeals for the circuit embracing the district[.]” 28 U.S.C. § 1294(1). She further argues that our jurisdiction under this statute is established by Medtronic AVE, Inc. v. Advanced Cardiovascular Systems, Inc., 247 F.3d 44 (3d Cir.2001).
Arunaehalam’s reliance on these authorities is misplaced. In the first place, the residual jurisdictional statute applies by its terms only to “appeals,” and a mandamus proceeding is not an “appeal.” See Madden v. Myers, 102 F.3d 74, 77 (3d Cir.1996). We could construe Arunachalám’s mandamus petition as a notice of appeal if appropriate, but there is no reason to do so because construing it as a notice of appeal would merely subject it to dismissal for other reasons as noted in the margin.3
Medtronic AVE is inapposite as well. In that case, we concluded that we had appellate jurisdiction to review an interlocutory but immediately appealable order denying a stay of a patent infringement action pending arbitration. See Medtronic AVE, 247 F.3d at 52-53. We acknowledged that, under 28 U.S.C. § 1295(a), the Federal Circuit would have exclusive appellate jurisdiction over any appeal from the final decision in that patent infringement action. See id. at 51-52. We reasoned, however, that the Federal Circuit’s appellate jurisdiction under § 1295(a) extends only to “final decisions” and that the order denying a stay pending arbitration was not a “final decision.” Id. at 52. Thus, we concluded that the Federal Circuit did not have appellate jurisdiction over that order and that we had such jurisdiction pursuant to the residual jurisdictional statute. See id. at 52-53. In doing so, we distinguished the decision in the mandamus context in In re BBC International cited above. As we explained, “our methodology [in the appellate context] 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.” Id. at 53.
In the mandamus context, by contrast, our analysis is indeed confined by that very provision. Because we may issue writs of mandamus only “in aid of’ our jurisdiction, and because we will not possess appellate jurisdiction over the final *294orders in these patent infringement actions, we do not have jurisdiction over Arunachalam’s mandamus petition. Such jurisdiction lies exclusively with the Federal Circuit.
For these reasons, it is hereby ORDERED that the Clerk transfer the mandamus petition to the United States Court of Appeals for the Federal Circuit. See 28 U.S.C. § 1631. We express no opinion on the merits of the petition. Our disposition terminates this proceeding in this Court.
