Appellant Aquatherm Industries, Inc. (“Aquatherm”) appeals from a judgment entered on December 9, 1994, by the United States District Court for the Middle District of Florida, Anne C. Conway, Judge, dismissing Aquatherm’s federal antitrust and Lan-ham Act claims against appellee Florida Power & Light Company (“FPL”). On appeal, Aquatherm argues that the district court erred in concluding that res judicata barred Aquatherm’s claims under Florida preclusion law. While we agree with the district court that Aquatherm’s Lanham Act claims were barred, we find that res judicata did not preclude Aquatherm’s pursuit of its federal antitrust claims. We therefore affirm in part, reverse in part, and remand.
BACKGROUND
Aquatherm is a manufacturer of solar-powered heating systems for swimming pools. FPL is a regulated utility that sells electricity in an area of Florida containing more than 250,000 in-ground swimming pools. The underlying dispute in this case involves FPL’s statements to its customers regarding electric pool heat pumps and solar pool heaters, and Aquatherm’s contention that these statements have unfairly advantaged the market for pool heaters reliant on electricity.
Aquatherm and FPL have expended a great deal of energy on their journey to this court. Aquatherm commenced its suit in 1991 by filing state antitrust claims in Florida state court; it later amended its complaint to include a federal claim for unfair competition under the Lanham Act, 15 U.S.C. 1125(a) (1994). FPL then removed the action to the United States District Court for the Southern District of Florida, at which point Aquatherm voluntarily withdrew its Lanham Act claim. The District Court consequently remanded the action to state court.
*1391 After remand, Aquatherm again amended its complaint to include state law claims of trade libel and product disparagement. FPL moved for dismissal and the state court dismissed all of Aquatherm’s claims with prejudice in November 1992. The state court’s decision was affirmed by a Florida appellate court in March 1994.
Prior to dismissal of the state action, Aquatherm filed a federal action in the United States District Court for the Middle District of Florida in November 1992. The complaint alleged federal antitrust violations under the Sherman Act, 15 U.S.C. §§ 1 and 2 (1994), and reasserted Aquatherm’s Lan-ham Act claim. After Aquatherm amended this complaint to add antitrust claims under the Clayton Act, 15 U.S.C. § 15 (1994), FPL moved for dismissal. The district court stayed the action pending resolution of the state court appeal.
When the Florida appellate court affirmed the dismissal of Aquatherm’s claims, FPL renewed its motion to dismiss in the federal district court on the basis of res judicata and failure to state any colorable claim. In December 1994, the district court granted FPL’s motion to dismiss on the ground that res judicata barred Aquatherm’s antitrust and Lanham Act claims.
In this appeal, Aquatherm contends that the district court erred in its construction and application of res judicata principles in several ways: (1) by misapplying United States Supreme Court precedent to reach the conclusion that prior resolution of Aquat-herm’s state antitrust claims barred its later federal antitrust claims; (2) by misinterpreting Florida preclusion law to find that res judicata bars a subsequent antitrust claim when an earlier court lacked subject matter jurisdiction over the original antitrust claim; (3) by applying only two of the four elements required for res judicata under Florida law to hold that Aquatherm’s Lanham Act claim was barred; and (4) by ignoring the “manifest injustice” exception to res judicata. We agree with Aquatherm that the district court erred in its analysis of Aquatherm’s antitrust claims under res judicata principles. We therefore reverse the dismissal of the antitrust claims and remand for further proceedings. Because we find that the district court properly dismissed Aquatherm’s Lanham Act claim, we affirm that portion of the district court’s decision.
DISCUSSION
The application of res judicata principles to Aquatherm’s claims constitutes a pure question of law that we review
de novo. Meshulam v. General Motors Corp.,
1. Antitrust Claims
This case presents the question whether a federal district court may give a Florida court judgment preclusive effect in a federal action brought under antitrust laws that are within the exclusive jurisdiction of the federal courts and therefore could not have been raised in the state court proceeding due to lack of subject matter jurisdiction.
2
While this issue appears to be one of
*1392
first impression in this circuit, we are not without guidance: the Supreme Court has laid out the approach for determining whether a prior state court judgment may bar a later federal antitrust suit in
Marrese v. American Academy of Orthopaedic Surgeons,
In Marrese, the Court reversed a lower court ruling that held that, as a matter of federal law, res judicata barred federal antitrust claims in a federal suit brought after an Illinois state court judgment. Balancing the exclusivity of federal court jurisdiction over federal antitrust claims with the full faith and credit given state court proceedings pursuant to 28 U.S.C. § 1738, the Court outlined a two-step analysis for federal courts to apply in cases such as the one before us.
Marrese
directs a court “to look first to state preclusion law in determining the preclusive effects of a state court judgment.”
With respect to matters that were not decided in the state proceedings, ... claim preclusion generally does not apply where “[t]he plaintiff was unable to rely on a certain theory of the case or seek a certain remedy because of the limitations of the subject matter jurisdiction of the courts.... ” Restatement (Second) of Judgments § 26(l)(e) (1982). If state preclusion law includes this requirement of prior jurisdictional competency, which is generally true, a state judgment will not have claim preclusive effect on a cause of action within the exclusive jurisdiction of the federal courts.

Under
Marrese,
therefore, we must determine whether Florida law would give preclu-sive effect to a judgment by a Florida court that lacked subject matter jurisdiction over the original claims.
Id.
at 386,
It is well-established that the general rule against splitting causes of action does not apply when suit is brought in a court that does not have jurisdiction over all of a plaintiffs claims.
See Restatement.of Judgments (Second)
§ 25 cmt. e (1982) (“If ... the court in the first action would clearly not have had jurisdiction to entertain the omitted theory or ground ... then a second action in a competent court presenting the omitted theory or ground should be held not precluded.”); 18 Charles A. Wright, Arthur R. Miller, Edward H. Cooper,
Federal Practice and Procedure: Jurisdiction
§ 4470 (1981) (“On balance, it seems better to reject claim preclusion” when jurisdiction is exclusively federal);
see also Hayes v. Solomon,
From a review of Florida law, it appears that Florida does follow this general rule requiring subject matter jurisdiction over claims in the original action in order for res judicata to act as a bar to those claims in a later action. As stated in Florida Jurisprudence 2d:
The doctrine of res judicata applies to the judgments or decrees of courts of competent jurisdiction....
32 Fla.Jur.2d Judgments and Decrees § 130 (1994) (emphasis added).
*1393 In order for a judgment or decree to operate as a bar, it must be rendered by a court having jurisdiction over the parties and subject matter.
33 id. at § 177.
Case law also supports the conclusion that Florida does not permit preclusion unless the prior court had jurisdiction over the claim.
See, e.g., Albrecht v. State,
It is not surprising that neither party can offer, nor can we find, any direct statement made by the Florida courts on the particular problem presented here. As noted in Marrese, “a state court will not have occasion to address the specific question whether a state judgment has ... claim pre-clusive effect in a later action that can be brought only in federal court,”
The district court did. not engage in the above analysis, concluding instead that Aquatherm’s state antitrust claims, which of course were litigated in a court of competent jurisdiction below, barred any federal claim against the same defendant arising from the same facts. The district court also found that Aquatherm, once removed to federal court, was required to raise its federal antitrust claims in that forum. We believe both these holdings were in error.
First, Marrese directly rejected the proposition that asserting state antitrust claims can eliminate the right to bring federal antitrust claims in a subsequent federal action. The Seventh Circuit plurality opinion in Marrese had held:
[A] state court judgment bars the subsequent filing of a federal antitrust claim if the plaintiff could have brought a state antitrust claim under a state statute “materially identical” to the Sherman Act.
Marrese,
We ... reject a judicially created exception to § 1738 that effectively holds as a matter of federal law that a plaintiff can bring state law claims initially in state court only at the cost of forgoing subsequent federal antitrust claims.

Second, there is no authority for the district court’s proposition that Aquatherm was required to assert its federal claims when it found itself in federal court by virtue of removal. The district court rested its holding on our decision in
Olmstead v. Amoco Oil Co.,
The rule that the judgment of a court of limited jurisdiction concludes the entire claim assumes that the plaintiff might have commenced his action in a court in the same system of courts that was competent to give full relief. See Restatement (Second) of Judgments § 24, cmt. g (1982).
*1394
Marrese
recognizes that our “parallel systems of state and federal courts” raise concerns of comity in the application of res judicata.

II. Lanham Act Claims
Aquatherm’s Lanham Act claim differs from its antitrust claims in a crucial respect: Federal courts do not have exclusive jurisdiction over an action brought under the Lanham Act. 28 U.S.C. § 1338(a) (1994); 15 U.S.C. § 1121 (1994). Therefore, Aquatherm could have litigated its Lanham Act claim while in state court, but chose not to do so. The concurrent jurisdiction shared by the state and federal courts over the Lanham Act requires us to analyze res judicata under the standard set forth in
Migra v. Warren City School Dist. Bd. of Educ.,
In
Migra,
the Supreme Court held that when a federal cause of action can be initially litigated in either state or federal court, a federal court must look to the preclusion law of the state in which it sits to determine the res judicata effect of a prior judgment from a state court of competent jurisdiction.

guaranteed] ... a right to proceed to judgment in state court on [its] state claims and then turn to federal court for adjudication of [its] federal claims.
Id.
Instead, federal courts must give state court judgments full faith and credit under 28 U.S.C. § 1738 and apply the state’s preclusion law.
Id.
at 84,
Under Florida law, res judicata bars a second suit when a court of competent jurisdiction has entered final judgment in an earlier suit and the following four conditions are met:
identity of the thing sued for; identity of the cause of action; identity of the parties; [and] identity of the quality in the person for or against whom the claim is made.
Albrecht v. State,
Aquatherm argues, however, that its Lan-ham Act claim in federal court involved both a different cause of action and a different form of requested relief than the claims for trade libel and product disparagement it made in state court, and that therefore res judicata should not bar the litigation of the Lanham Act claim in federal court. We agree with neither of these contentions.
Albrecht
provides that “[t]he determining factor in deciding whether the cause of action is the same is whether the facts or evidence necessary to maintain the suit are the same in both actions.”
Aquatherm also can find no purchase with its argument that the compensatory damages it sought in state court were a different form of relief from the treble damages and profits it requested in federal court. Aquatherm relies exclusively on
Sivilla v. State Farm Mut. Auto. Ins. Go.,
Florida law is clear that “[t]he rule against splitting causes of action makes it incumbent upon plaintiffs to raise all available claims involving the same circumstances in one action.”
Department of Agric. and Consumer Serv. v. Mid-Florida Growers, Inc.,
CONCLUSION
For the foregoing reasons, we REVERSE the dismissal of Aquatherm’s antitrust claims and REMAND to the district court for farther proceedings. We AFFIRM the dismissal of the Lanham Act claim.
Notes
. As noted by the Supreme Court, the terminology used to discuss the preclusive effects of earlier litigation is somewhat confusing because res judicata is often used to refer both to claim preclusion and to issue preclusion.
Migra v. Warren City Sch. Dist. Bd. of Educ.,
. Exclusive federal jurisdiction is provided by statute for Sherman Act claims, 15 U.S.C. § 4 (1994), and Clayton Act claims, 15 U.S.C. § 15 (1994).
See Freeman v. Bee Machine Co., Inc.,
. Illustration 11 reads:
A sues B on a common law basis in a state court for unfair competition. After trial judgment is entered for the defendant. A then attempts to bring an action against B in federal court upon the same behavior, now claiming infringement of A’s federally protected trademark. The action is barred. The claimed violation of federal right could have been urged as a ground of liability in the state court action, as state courts have concurrent jurisdiction with the federal courts to enforce that right.
. Aquatherm also contends that to allow res judi-cata to bar its Lanham Act claim would work a “manifest injustice.” After reviewing the argument for this contention, we deem it wholly without merit.
