DECISION AND ORDER
I. FACTUAL AND PROCEDURAL BACKGROUND
Plaintiff Barbara A. Meyers filed this action in state court against defendants Bayer AG and other corporations alleging claims under Wisconsin antitrust and deceptive trade practice laws on behalf of herself and other Wisconsin indirect purchasers of the patented drug ciprofloxacin hydrochloride (“Cipro”). Cipro is a widely used antibiotic; according to plaintiff, it has been the best selling antibiotic in the world for eight consecutive years. Plaintiff alleges that defendant Bayer, which developed and patented Cipro, violated state law by agreeing to pay the other defendants to refrain from marketing a generic Cipro equivalent. 1
Defendants timely removed the case to this court alleging that federal question jurisdiction exists pursuant to 28 U.S.C. §§ 1331 & 1338, because a substantial question of federal patent law must be resolved to decide an essential element of plaintiffs state law antitrust claim, Spe *1046 cifically, defendants contend that plaintiff could prove that she suffered antitrust injury only by demonstrating that Bayer’s Cipro patent is invalid. Alternatively, defendants assert the existence of diversity jurisdiction under 28 U.S.C. § 1332 because the action is between citizens of different states and the amount in controversy is alleged to exceed $75,000. Plaintiff disputes the existence of either federal question or diversity jurisdiction and moves that the case be remanded to state court.
Defendants, in turn, move for a stay of all further proceedings in the case, including the motion to remand, pending a determination by the Judicial Panel on Multidis-trict Litigation (“JPML”) as to whether to transfer the case to the Eastern District of New York pursuant to 28 U.S.C. § 1407. The present case- is one of more than thirty lawsuits filed in state and federal courts in the United States in recent months raising similar or identical claims about Cipro. On December 11, 2000, the JPML ordered six of the cases consolidated and transferred to the Eastern District of New York.

MDL Docket No. 1383 [hereinafter “the MDL proceeding”],
II. DISCUSSION
The MDL system provides for the transfer of actions with one or more common questions of fact to a single district for coordinated pretrial proceedings. 28 U.S.C. § 1407(a). Congress authorized the JPML • to order transfers only after determining that transfer “will be for the convenience of parties and witnesses and will promote the just and efficient conduct of such actions,” id., and with the expectation that transfers will be ordered “only where significant economy and efficiency in judicial administration may be obtained,” H.R.Rep. No. 90-1130 (1968), reprinted in 1968 U.S.C.C.A.N. 1898, 1900.
A pending JPML transfer motion or conditional transfer order does not affect the jurisdiction of the transferor court or its ability to rule upon any pending motions. Rules of Procedure of the JPML R. 1.5;
Gen. Elec. Co. v. Byrne,
A. Judicial Power
In support of her contention that I must address the remand issue first, plaintiff cites the “bedrock principle of federal law” (PL’s Mem. in Opp. to Defs.’ Mot. to Stay at 8), expressed in
Ex Parte McCardle,
To say that I am powerless to take any action at all before verifying my jurisdiction, however, slightly overstates the matter. For example, it is a “primordial element of our jurisprudence” that federal courts have jurisdiction to determine whether they have subject matter jurisdiction.
Shannon v. Shannon,
Further, “the power to stay proceedings is incidental to the power inherent in every court to control the disposition of the causes on its docket with economy of time and effort for itself, for counsel, and for litigants.”
Landis v. N. Am. Co.,
B. Methodology
Analyzing the question from the standpoint of judicial power does not resolve the question of whether the remand and stay motions should be addressed together or separately, and if separately, in what order. Neither does the
Manual for Complex Litigation (Third)
’s observation that the pendency of a transfer motion “should not automatically ... postpone rulings on pending motions.” § 31.131 at 252 (1995). Courts have divided in other cases, sometimes granting motions to remand and sometimes deferring consideration of such motions to the JPML by granting stays.
Compare Aetna U.S. Healthcare, Inc. v. Hoechst Aktiengesellschaft,
My view is that a court’s first step should be to make a preliminary assessment of the jurisdictional issue. Although
Landis
might be read to empower me to stay the case without making any effort to verify jurisdiction, I am, nevertheless, reluctant to do so. First,
Steel Co.
emphasized the constitutional importance of the “jurisdiction first” principle. Second, 28 U.S.C. § 1447(c) directs that “[i]f at any time before judgment it appears that the district court lacks subject matter jurisdiction, the case
shall
be remanded.” (emphasis added). This section dictates that a judge should give at least some consideration to a remand motion. The third reason is judicial economy. “If the limited review reveals that the case is a sure loser in the court that has jurisdiction (in the conventional sense) over it, then the [transferor] court ... should dismiss the case rather than waste the time of another court.”
Phillips v. Seiter,
The fourth reason is that even though a stay does mot directly implicate the merits of a case, it undeniably has important effects on the litigation. A plaintiff may carefully craft a state court complaint in order to avoid litigating the matter in federal court.
Garbie v. DaimlerChrysler Corp.,
Removing a case to federal court has long been known to impose a burden upon plaintiffs; at a minimum, it requires the plaintiff to present its arguments for remand in a foreign forum, often at a considerable distance from the local county courthouse and before a judge who might be less sympathetic to the plaintiffs cause than a judge who is local (and often, elected). Edward A. Purcell, Jr.,
Litigation and Inequality: Federal Diversity Jurisdiction in Industrial America, 1870-1958
25, 52-53 (1992). Concerns about being haled into distant courts are particularly implicated by the MDL system. Not only is the judge unknown, but the proceeding is all but certain to be even farther from home, and plaintiffs chosen counsel may have little power to shape the course of the litigation. Earle F. Kyle, IV,
The Mechanics of Motion Practice Before the Judicial Panel on Multidistrict Litigation,
*1049 This case is an example in point. Plaintiff originally filed her action in Milwaukee County Circuit Court and defendants removed to the U.S. District Court for the Eastern District of Wisconsin (which in this instance is also located in Milwaukee); but plaintiffs opposition to the JPML’s conditional transfer order will be heard in Washington, D.C., and if a final transfer order is entered, plaintiff will find herself litigating in the U.S. District Court for the Eastern District of New York.
For the four reasons discussed, then, a court should first give preliminary scrutiny to the merits of the motion to remand. If this preliminary assessment suggests that removal was improper, the court should promptly complete its consideration and remand the case to state court.
If, on the other hand, the jurisdictional issue appears factually or legally difficult, the court’s second step should be to determine whether identical or similar jurisdictional issues have been raised in other cases that have been or may be transferred to the MDL proceeding. The only reason to permit the transferee court to decide the jurisdictional issue would be to further judicial economy and consistency. H.R.Rep. No. 90-1190. If the jurisdictional issue in the particular case is different from those in the other cases subject or potentially subject to MDL jurisdiction, these values do not come into play. The
Manual for Complex Litigation (Third)
suggests that the transferee court should resolve motions to dismiss or to remand “raising issues unique to the particular case” before the JPML decides the motion to transfer. § 31.131 at 252. Thus, in
Kohl v. American Home Products Corp.,
Only if the jurisdictional issue is both difficult and similar or identical to those in cases transferred or likely to be transferred should the court proceed to the third step and consider the motion to stay. But considering the motion to stay does not mandate that a stay should be granted; the factors to be considered include (1) the interests of judicial economy; (2) hardship and inequity to the moving party if the action is not stayed; and (3) potential prejudice to the non-moving party.
Rivers v. Walt Disney Co.,
C. Application of Methodology to Facts
1. Preliminary Assessment of Jurisdictional Issue
As discussed above, I first make a preliminary assessment of the jurisdictional issue. A case may be removed to federal *1050 court only if it could initially have been_ filed in federal court. 28 U.S.C. § 1441(a). Defendants assert both diversity and federal question jurisdiction.
a. Diversity Jurisdiction
Diversity jurisdiction requires complete diversity of citizenship and a certain amount in controversy, currently $75,000. 28 U.S.C. § 1332(a). As the party alleging diversity jurisdiction, defendants bear the burden of proof.
Chase v. Shop ‘N Save Warehouse Foods, Inc.,
A class action satisfies the amount in controversy requirement only if at least one class member’s claim satisfies the jurisdictional minimum.
In re Brand Name Prescription Drugs Antitrust Litig.,
Whether the jurisdictional amount is satisfied is determined as of the date that the complaint is filed; what happens later is irrelevant.
St. Paul Mercury Indem. v. Red Cab Co.,
Plaintiff alleges that her and other class members’ damages are not in excess of $75,000. Defendants correctly observe that plaintiff demands statutory treble antitrust damages, which makes the relevant damages threshold $25,000.
W. Bend Elevator, Inc. v. Rhone-Poulenc S.A.,
b. Federal Question Jurisdiction
Federal question jurisdiction exists where the action arises under federal law. *1051 28 U.S.C. § 1331. According to the Supreme Court:
Jurisdiction extends only to those cases in which a well pleaded complaint establishes either [1] that federal patent law creates the cause of action or [2] that the plaintiffs right to relieve necessarily depends on resolution of a substantial question of federal patent law, in that patent law is a necessary element of one of the well pleaded claims.
Christianson v. Colt Indus. Operating Corp.,
The rule is that a claim arises under federal law only if federal law is a necessary element of one of the well-pleaded claims of the complaint.
Christianson,
Unfortunately, it is not an easy matter to apply this rule. As one commentator has observed:
In summary, by its Christianson decision, the Court reaffirmed the viability of the well-pleaded complaint rule and its collateral principles as applied to patent jurisdiction: patent jurisdiction exists only if patent law creates or is a necessary element of the action; federal jurisdiction cannot derive from a defense raised in the answer or anticipated in the complaint; and a mere theory of liability requiring construction or application of the patent laws does not establish patent jurisdiction, unless that patent law theory is an essential element of the plaintiffs state law claim. For all that, however, the Court left unclear how to determine whether a specific case in fact arises under the patent laws.
Amy B. Cohen, “Arising Under” Jurisdiction and the Copyright Laws, 44 Hastings L.J. 337, 360 (1993) (emphasis added).
Nor does looking to other courts that have applied
Christianson
make it easier to tell when a challenge to a patent’s validity is implicated by a state law claim, rather than merely by a theory that supports a state law claim. In the only other reported decision to date addressing this aspect of the Cipro litigation,
Altman v. Bayer Corp.,
I agree with much of Judge McMahon’s reasoning. Defendants, however, draw upon
Hunter Douglas, Inc. v. Harmonic Design, Inc.,
In this case, defendants argue (1) that injury and causation are essential elements of plaintiffs state law claims; (2) that plaintiffs sole alleged injury is her inability to purchase less expensive, generic versions of Cipro, and her sole causation argument is that but for defendants’ challenged conduct, a generic Cipro would have been marketed by January 1997; (3) however, Bayer’s patent is good until 2003, and if its patent is valid Bayer has the right to prevent competitors from selling generic versions of Cipro until then; and (4) whether Bayer’s patent is valid involves a substantial question of federal law.
Defendants’ argument is somewhat mis-framed. Under Wisconsin’s antitrust and deceptive trade practice statutes, injury and causation become relevant only after a statutory violation is established. 5 Defendants surely do not concede that they have violated these statutes. Moreover, the validity or invalidity of Bayer’s patent seems to have little to do with the prices that plaintiff paid for drugs (injury) or whether, due to defendants’ conduct, plaintiff paid higher prices (causation). To the contrary, defendants’ argument must be that plaintiff would have to establish the invalidity of the patent in order to prove that defendants violated the relevant statutes. 6
But defendants’ framing of their argument does not affect the present analysis. To show that defendants’ agreements were unlawful restraints of trade, and that the effect of those agreements was to deceive Cipro customers, plaintiffs would need to show that Bayer’s patent was invalid. Altman, 125 F.Supp.2d at 673 (“Bayer has an absolute right to keep generics out of the *1053 market until 2003 if the patent is valid.”). Although I am inclined towards Altman’s interpretation of Christianson over Hunter Douglas’s interpretation, it is not an easy call.
2. Commonality of Jurisdictional Issue
Because the jurisdictional issue is difficult, I next assess whether it is common to other cases that have been or may be transferred to the MDL proceeding. Defendants state, and plaintiffs do not dispute, that eighteen of the cases subject or potentially subject to such transfer have been removed from state courts, and that similar remand motions challenging federal question jurisdiction have arisen in eight of those cases. The jurisdictional issue is both difficult and common.
3. Propriety of Stay
I therefore assess whether a stay is appropriate. As previously stated, the factors to be considered include (1) the interests of judicial economy; (2) hardship and inequity to the moving party if the action is not stayed; and (3) potential prejudice to the non-moving party.
Rivers,
Because as eight other cases present the same or a similar issue as is presented here, judicial economy clearly favors a stay. Defendants contend that unless a stay is granted, they will be forced to litigate the same issue in multiple courts. .1 give no weight to this argument, though, as the parties have fully briefed the remand issue before me. Plaintiff for her part contends that if a stay is granted, she “must endure indefinite delay” while waiting for the JPML to determine whether to transfer this case and, if a final transfer order is entered, waiting for the transferee court to address her remand motion. I acknowledge that delays do impose burdens but have no reason to believe that a ruling on the remand issue would be substantially delayed. Although the prejudice needed to tip the balance in a plaintiffs favor surely need not be as great as in Mauck, the record gives me no reason to believe that delay would be particularly injurious to this plaintiff in this case. My assessment is that the gains in judicial economy from issuing the stay outweigh the burdens to plaintiff.
NOW, THEREFORE, IT IS HEREBY ORDERED that plaintiffs motion for remand is GRANTED to the extent that the court FINDS that diversity jurisdiction is lacking, but is OTHERWISE DEFERRED UNTIL THE JPML DECIDES WHETHER TO TRANSFER THIS ACTION.
IT IS FURTHER ORDERED that defendants’ motion for a stay is GRANTED until the JPML decides whether to transfer this action.

. This action is thus part of what a recent news article described as "growing scrutiny of generic drugs and the relationships between generic drug manufacturers and large, brand-name pharmaceutical companies.” Liz Kowalczyk, Consumer Group Sues over Price of Cancer Drug, Boston Globe, May 10, 2001, at Al.
. I thus decline to follow the approach of
Farkas v. Bridgestone/Firestone, Inc.,
. Dicta in
Sarnoff v. American Home Products Corp.,
. Indeed, the Supreme Court "assume[d] without deciding that the invalidity of Colt's patents is an essential element of the foregoing monopolization theory.”
Christianson,
. The antitrust statute provides a cause of action to "any person injured, directly or indirectly, by reason of anything prohibited by this chapter,” Wis. Stat. Ann. § 133.18(1 )(a) (West Supp.2000), while the unfair trade practice statute provides a cause of action to "[a]ny person suffering pecuniary loss because of a violation of this section,” id. § 100.18(1 l)(b)(2).
. Plaintiff alleges that defendants’ settlement agreement was an illegal contract, combination or conspiracy in restraint of trade under § 133.03(1) of the antitrust statute, and that defendants deceived customers, in violation of the unfair trade practices statute, § 100.18(1), into believing that Cipro prices were the result of market competition rather than illegal payoffs to keep generics off the market.
