MEMORANDUM OPINION AND ORDER
Plaintiff Gary Schor filed a three-count class action complaint against defendant *852 Abbott Laboratories (“Abbott”), alleging violations of the Sherman Antitrust Act (“Sherman Act”), 15 U.S.C. § 2, and the Illinois Consumer Fraud Act, 815 ILCS 505/1, et seq. Plaintiff also asserts a state law claim for unjust enrichment. Plaintiff alleges that defendant used its monopoly over its patented AIDS drug Norvir to unreasonably inflate the price of competitors’ drug combinations that contain Nor-vir.
Subject matter jurisdiction of the Sherman Act claim is based on 28 U.S.C. §§ 1331 and 1337, and 15 U.S.C. § 15. Jurisdiction over the state law claims is based on supplemental jurisdiction pursuant to 28 U.S.C. § 1367.
Defendant has moved to dismiss the complaint pursuant to Fed.R.Civ.P. 12(b)(6) for failure to state a claim. For the reasons discussed below, the court grants defendant’s motion to dismiss Count I, and declines to exercise supplemental jurisdiction over the state law claims.
FACTS 1
Defendant Abbott, an Illinois corporation, is a pharmaceutical company engaged in the business of manufacturing, developing, and distributing anti-retroviral drugs worldwide, including throughout the United States. Plaintiff, a citizen of Florida, purchased one of defendant’s AIDS drugs, Norvir, for his personal use.
Norvir was originally marketed as a stand-alone protease inhibitor (“PI”). Pis are anti-retroviral drugs that inhibit the AIDS virus from copying itself into new cells. Plaintiff alleges that Norvir cannot be interchanged with any other drug, and therefore constitutes a product market subject to antitrust laws. Through various patents, defendant controls 100% of the Norvir market, and there are no generic versions of Norvir. Norvir causes severe side effects when used alone, but when taken in conjunction with other Pis, it boosts the effectiveness of the other drugs. These “boosted Pis” also remain effective for longer periods of time. It is important for AIDS patients to have a variety of Pis available to them because patients may build a tolerance to certain drug combinations.
Defendant produces its own boosted PI, called Kaletra, which is boosted by Norvir. At least seven other boosted Pis, not manufactured by defendant, are boosted by Norvir: Agenerase, Crixivan, Fortovase, Invirase, Lexiva, Reyataz, and Viracept. Plaintiff alleges that Pis boosted by Nor-vir are not interchangeable with any other drugs and are a market subject to antitrust laws. Plaintiff asserts that defendant effectively controls this market for “all of the anti-retroviral drugs dependent on a boost from Norvir in the United States,” and that the United States is a proper geographical market for antitrust purposes.
Kaletra, defendant’s boosted PI, began to lose its market share in 2003. In December 2003, defendant raised the price of Norvir by more than 400%. 'Defendant did not, however, pass this price increase on to Kaletra. As a result, Kaletra costs substantially less than other boosted Pis. Plaintiff asserts that defendant’s “anticom-petitive pricing scheme is designed to exclude competition for Kaletra, even though Kaletra might not be the most effective PI for a particular patient.” Prior to the increase, it was projected that defendant would receive over $2 billion in revenues *853 for Norvir. According to plaintiff, defendant “had no legitimate justification for the exorbitant price increase of Norvir other than to strangle the market to the detriment of AIDS victims.”
DISCUSSION
In ruling on a motion to dismiss for failure to state a claim, the court accepts the allegations of the complaint as true and views the facts in the light most favorable to the plaintiff.
Travel All Over the World,
I. Collateral estoppel
Plaintiff argues in his response to the motion to dismiss that defendant is collaterally estopped from raising its arguments in favor of its motion to dismiss by two earlier decisions issued by Judge Wilken of the Northern District of California,
Doe v. Abbott Laboratories,
C 04-1511 CW, un-pub. order (N.D.Cal. Oct. 21, 2004), and
Service Employees International Union Health and Welfare Fund v. Abbott Laboratories,
. In the instant case, defendant argues that collateral estoppel does not apply because a ruling on a motion to dismiss is not a “final judgment,” and thus does not trigger collateral estoppel.
2
Collateral estoppel, or issue preclusion, bars the litigation in a subsequent action of an issue that has been decided in a prior action.
Meyer v. Rigdon,
Although defendant is correct that a ruling denying a motion to dismiss is typically not a final judgment for the purposes of collateral estoppel, the Seventh Circuit has *854 held that there are instances in which a motion to dismiss ruling may have preclu-sive effect. For example, the Gilldom court held that a district court’s denial of a motion to dismiss was sufficiently final for purposes of collateral estoppel. Id. In Gilldom, an Illinois district court judge granted the plaintiffs motion to enjoin a pending action brought by the defendant in Texas, based on the plaintiffs argument that the Texas action should have been brought as a compulsory counterclaim in the Illinois action. The plaintiff, however, had already moved for dismissal in the Texas action, and had made the compulsory counterclaim argument, along with others, unsuccessfully. Id. at 391. The Seventh Circuit held that the Illinois district court should have given collateral estoppel effect to the Texas district court’s denial of the plaintiffs dismissal motion. Id. at 395.
In support of its holding that a denial of a motion to dismiss may, in some cases, operate as collateral estoppel, the
Gilldom
court cited the Seventh Circuit’s earlier holding in
Miller Brewing Co. v. Joseph Schlitz Brewing Co.,
Judge Wilken’s findings regarding the California plaintiffs’ Sherman Act claims do not have collateral estoppel effect in the instant case.

First, most of the “holdings” listed by plaintiff in its brief are not in fact holdings. The plaintiffs in
Doe
and
Service Employees,
like plaintiff in the instant case, rely on a “monopoly leveraging theory” of antitrust liability. Although the Ninth Circuit applied this theory to a patentee in
Image Technical Services, Inc. v. Eastman Kodak, Co.,
*855
Second, although Judge Wilken held that the plaintiffs in
Doe
and
Service Employees
had standing as indirect consumers of Norvir to pursue their Sherman Act claims, the Seventh Circuit has held that the “denial of a motion to dismiss for lack of standing does not qualify as a final judgment.”
Triad Assocs., Inc. v. Robinson,
II. Sherman Act
Count I of plaintiffs complaint alleges that defendant violated § 2 of the Sherman Act by abusing its monopoly power in the U.S. market for Norvir, its patented product, to unfairly injure competition in the market for Pis boosted by Norvir. 4 Defendant’s own boosted PI, Kaletra, competes in this second market with approximately seven other Pis boosted by Norvir. Defendant argues that Count I should be dismissed because its patents for Norvir, which cover its use as a stand-alone drug and as a booster when combined with other Pis, preclude antitrust liability. Defendant also argues that plaintiff fails to sufficiently allege defendant’s market power in the boosted PI market, arid that plaintiff lacks standing to obtain relief under the Sherman Act because he is an indirect consumer and has failed to allege that he suffered any antitrust injuries. 5
The instant case reveals the tension between antitrust laws, which discourage monopolies, and patent laws, which protect monopolies.
See Image Technical Servs., Inc. v. Eastman Kodak Co.,
Although not a model of clarity in antitrust pleading, plaintiffs complaint alleges two separate markets: the Norvir market and the market of Pis boosted by Norvir. Plaintiff clarifies in his response to the motion to dismiss that he does not dispute the validity of the Norvir patents or defendant’s lawful monopoly in the Norvir market. Instead, he is challenging defendant’s use of its monopoly of the Norvir market to attain a monopoly in the boosted PI market. Plaintiffs Sherman Act claim is premised on an extension' of the monopoly leveraging theory to patent holders, under which antitrust liability may be based on the improper use of a monopoly in one market to strengthen or create a monopoly in another market.
Virgin Atlantic Airways Ltd. v. British Airways PLC,
The Supreme Court emphasized in
Verizon Communications Inc. v. Law Offices of Curtis V. Trinko, LLP,
There is sparse case law regarding if or how the monopoly leveraging theory applies to conduct by a patentee, and what little case law there is does not concern a price increase by a patent holder. In the instant case, both parties cite to opinions addressing whether a patentee’s refusal to deal- — -to license or sell its patented product — is a violation of antitrust law. The court agrees with the parties’ implicit assumption that it is appropriate to analogize refusal to deal cases with the price increase at issue here because if a patentee has the right to refuse to sell its product altogether, it has the right to raise the price.
See Zenith Laboratories, Inc. v. Carter-Wallace, Inc.,
The Ninth Circuit was the first court to examine the antitrust liability of a patent holder under the monopoly leveraging theory. Sharon Brawner MeCullen, Comment,
The Federal Circuit and Ninth Circuit Face-Off: Does A Patent Holder Violate the Sherman Act By Unilaterally Excluding Others From A Patented Invention In More Than One Relevant Market?,
74 Temp. L. Rev.469, 500 (2001). In
Image Technical Services, Inc. v. Eastman Kodak, Co.,
In
Kodak II
the Ninth Circuit extended earlier monopoly leveraging precedent to antitrust cases involving patented products, and-limited a patent holder’s right to exclude others to a single market.
Id.
at 1217-18.
Kodak II
held that Kodak violated § 2 of the Sherman Act when it refused to sell its patented parts for use by independent service organization in the secondary service market. In support of its finding, the
Kodak II
court relied in part on a footnote in the Supreme Court’s opinion affirming the Ninth Circuit’s earlier denial of summary judgment.
Id.
at 1215-16. Addressing the plaintiffs’ § 2 monopolization claim, the Court rejected the argument that a manufacturer competing in the secondary service market enjoys
per se
immunity to antitrust laws.
Eastman Kodak Co. v. Image Technical Services, Inc.,
Three years later, and faced with a very similar factual situation to
Kodak II,
the Federal Circuit expressly rejected the Ninth Circuit’s reasoning, and held that a patent holder does not violate the Sherman Act by refusing to license or sell a patented item in a second market, even when the patented product is necessary to the second market.
In re Independent Service Organizations Antitrust Litigation CSU, L.L.C., v. Xerox,
Defendant in the instant case incorrectly argues that
Xerox
is binding precedent because the instant case involves patents, and therefore the law of the Federal Cim cuit, rather than Seventh or Ninth Circuit law, controls.
See In re Spalding Sports Worldwide, Inc.,
Regardless of which circuit’s law must control, for the reasons discussed below the court finds the Xerox court’s reasoning persuasive, and that the holding represents a sounder approach to a patentee’s antitrust liability in a second market than the Ninth Circuit’s opinion in Kodak II. The court agrees with the Federal Circuit that subject to narrow limitations, not at issue in thé instant case, a patentee’s exercise of its statutorily-granted market power does not constitute a Sherman Act violation, even if such conduct affects a second market. The Federal Circuit’s decision is in keeping with the case law and the statutory language suggesting that a court must consider the scope of the patent grant when determining whether an antitrust violation has occurred, and properly holds that a patentee is not liable for conduct within the. scope of its valid patent grant.
A patent holder may, of course, violate the Sherman Act by excluding others from inventions beyond the scope of the patent.
Ethyl Gasoline Corp. v. United States,
The court agrees with the
Xerox
court that footnote 29 in the Supreme Court’s decision in
Kodak I,
which suggests that a patentee’s expansion into a second market may be an antitrust violation, is largely inapposite to the facts of
Kodak II
and
Xerox,
and was incorrectly applied by the Ninth Circuit in
Kodak II.
As the Federal Circuit noted,
Kodak I
was a tying case when it came before the Supreme Court, and no patents had been asserted in defense of the antitrust claims against Kodak.
Xerox,
The Federal Circuit cited section 271(d) of the Patent Act, which immunizes a patent holder against certain liabilities, in support of its expansion of a patentee’s rights into a second market.
Xerox,
Lastly, the instant case is factually distinguishable from Kodak II and Xerox in aspects that support defendant’s argument that it should not be subject to antitrust liability for raising the price of Norvir. First, defendant’s patents cover Norvir’s use in the stand-alone market as well as the boosted PI market. Plaintiff does not challenge defendant’s assertion that its patents “explicitly cover the use of Norvir as a ‘booster’ in combination with another Pis.” In Xerox and Kodak II, in contrast, the second market at issue was a service and repair market, which was apparently not covered by the defendants’ patent grants. Here, the alleged second market is for compound products containing the *860 first market’s product, and plaintiff does not argue that defendant’s use of Norvir in Kaletra or its sale of Norvir as a booster for competitors’ boosted Pis exceeds the patent grant. Unlike Xerox and Kodak II, defendant’s Norvir patents apply in both markets to cover Norvir’s use in conjunction with drugs manufactured and sold by third parties.
Second, in
Xerox
the Federal Circuit determined that the defendant’s refusal to deal was within the scope of its patent claims and thus permissible.
To accept plaintiffs argument would seem to impose antitrust liability on any manufacturer who holds patents for a product when used alone as well as for its use as a component in products manufactured by the patentee and competitors, and raises the price it charges competitors for its patented component. Such a result runs contrary to the aims of the antitrust and patent laws to encourage innovation and competition, and is not supported by the case law. The Supreme Court has held that the Sherman Act was enacted to prevent restraint of commerce, but has explicitly recognized the patent grant as an exception.
United States v. Line Material Co.,
For the reasons stated above, defendant may not be held liable for a violation of § 2 of the Sherman Act for increasing the price of its patented product, even though that price increase may affect competition in a second market. Accordingly, the court grants defendant’s motion to dismiss Count I with prejudice.
Because the court grants defendant’s motion to dismiss Count I, it need not reach defendant’s alternative arguments that plaintiff failed to allege market power or that plaintiff lacks standing as an indirect consumer to pursue injunctive relief. In addition, the court declines to exercise supplemental jurisdiction over the remaining state law claims. Accordingly, the court grants defendant’s motion to dismiss Counts II and III without prejudice.
CONCLUSION
For the reasons stated above, the court grants defendant’s motion to dismiss the complaint. Count I is dismissed with prejudice. Counts II and III are dismissed without prejudice.
Notes
. For the purposes of a motion to dismiss, the court accepts all well-pleaded allegations as true and draws all reasonable inferences in favor of the plaintiff.
Travel All Over the World., Inc. v. Kingdom of Saudi Arabia,
.
Defendant also argues that collateral estop-pel does not apply because the California court "did not address 'identical' issues” to those presented in the instant case. In its joinder motion filed with the Judicial Panel on Multi-District Litigation ("MDL”), however, defendant asserts that the instant case and
Doe
and
Service Employees
"are based on identical facts and allege identical legal theories.” Judicial estoppel prevents a party that has taken one position in litigating a particular set of facts from later reversing its position when it is to its advantage to do so, if the party to be estopped has convinced the court to adopt its position.
Levinson v. United States,
. Although the court does not reach plaintiff's state law claims, it is clear that Judge Wilken’s rulings on the California plaintiffs' state law claims, brought under California law, do not have a collateral estoppel effect on a court applying Illinois law.
. Section 2 of the Sherman Act, 15 U.S.C. § 2, prohibits monopolization or attempts to monopolize: “Every person who shall monopolize, or attempt to monopolize, or combine or conspire with any other person or persons, to monopolize any part of the trade or commerce among the several States, or with foreign nations, shall be deemed guilty of a felony..
. In plaintiff’s response to the motion to dismiss, he withdraws his claims for damages under Count I of his complaint, and now seeks only injunctive relief.
