Justice SCALIA delivered the opinion of the Court.

This case requires us to decide whether respondent, Static Control Components, Inc., may sue petitioner, Lexmark International, Inc., for false advertising under the Lanham Act, 15 U.S.C. § 1125(a).

I. Background

Lexmark manufactures and sells laser printers. It also sells toner cartridges for those printers (toner being the powdery ink that laser printers use to create images on paper). Lexmark designs its printers to work only with its own style of cartridges, and it therefore dominates the market for cartridges compatible with its printers. That market, however, is not devoid of competitors. Other businesses, called "remanufacturers," acquire used Lexmark toner cartridges, refurbish them, and sell them in competition with new and refurbished cartridges sold by Lexmark.

Lexmark would prefer that its customers return their empty cartridges to it for refurbishment and resale, rather than sell those cartridges to a remanufacturer. So Lexmark introduced what it called a "Prebate" program, which enabled customers to purchase new toner cartridges at a 20-percent discount if they would agree to return the cartridge to Lexmark once it was empty. Those terms were communicated to consumers through notices printed on the toner-cartridge boxes, which advised the consumer that opening the box would indicate assent to the terms — a practice commonly known as "shrinkwrap licensing," see, e.g., ProCD, Inc. v. Zeidenberg, 86 F.3d 1447, 1449 (C.A.7 1996). To enforce the Prebate terms, Lexmark included a microchip in each Prebate cartridge that would disable the cartridge after it ran out of toner; for the cartridge to be used again, the microchip would have to be replaced by Lexmark.

Static Control is not itself a manufacturer or remanufacturer of toner cartridges. It is, rather, "the market leader [in] making and selling the components necessary to remanufacture Lexmark cartridges." 697 F.3d 387, 396 (C.A.6 2012) (case below). In addition to supplying remanufacturers with toner and various replacement parts, Static Control developed a microchip that could mimic the microchip in Lexmark's Prebate cartridges. By purchasing Static Control's microchips and using them to replace the Lexmark microchip, remanufacturers were able to refurbish and resell used Prebate cartridges.

Lexmark did not take kindly to that development. In 2002, it sued Static Control, alleging that Static Control's microchips violated both the Copyright Act of 1976, 17 U.S.C. § 101 et seq., and the Digital Millennium Copyright Act, 17 U.S.C. § 1201 et seq. Static Control counterclaimed, alleging, among other things, violations of § 43(a) of the Lanham Act, 60 Stat. 441, codified at 15 U.S.C. § 1125(a). Section 1125(a) provides:

Section 1125(a) thus creates two distinct bases of liability: false association, § 1125(a)(1)(A), and false advertising, § 1125(a)(1)(B). See Waits v. Frito-Lay, Inc., 978 F.2d 1093, 1108 (C.A.9 1992). Static Control alleged only false advertising.

As relevant to its Lanham Act claim, Static Control alleged two types of false or misleading conduct by Lexmark. First, it alleged that through its Prebate program Lexmark "purposefully misleads end-users" to believe that they are legally bound by the Prebate terms and are thus required to return the Prebate-labeled cartridge to Lexmark after a single use. App. 31, ¶ 39. Second, it alleged that upon introducing the Prebate program, Lexmark "sent letters to most of the companies in the toner cartridge remanufacturing business" falsely advising those companies that it was illegal to sell refurbished Prebate cartridges and, in particular, that it was illegal to use Static Control's products to refurbish those cartridges. Id., at 29, ¶ 35. Static Control asserted that by those statements, Lexmark had materially misrepresented "the nature, characteristics, and qualities" of both its own products and Static Control's products. Id., at 43-44, ¶ 85. It further maintained that Lexmark's misrepresentations had "proximately caused and [we]re likely to cause injury to [Static Control] by diverting sales from [Static Control] to Lexmark," and had "substantially injured [its] business reputation" by "leading consumers and others in the trade to believe that [Static Control] is engaged in illegal conduct." Id., at 44, ¶ 88. Static Control sought treble damages, attorney's fees and costs, and injunctive relief.1

The District Court granted Lexmark's motion to dismiss Static Control's Lanham Act claim. It held that Static Control lacked "prudential standing" to bring that claim, App. to Pet. for Cert. 83, relying on a multifactor balancing test it attributed to Associated Gen. Contractors of Cal., Inc. v. Carpenters, 459 U.S. 519, 103 S.Ct. 897, 74 L.Ed.2d 723 (1983). The court emphasized that there were "more direct plaintiffs in the form of remanufacturers of Lexmark's cartridges"; that Static Control's injury was "remot[e]" because it was a mere "byproduct of the supposed manipulation of consumers' relationships with remanufacturers"; and that Lexmark's "alleged intent [was] to dry up spent cartridge supplies at the remanufacturing level, rather than at [Static Control]'s supply level, making remanufacturers Lexmark's alleged intended target." App. to Pet. for Cert. 83.

The Sixth Circuit reversed the dismissal of Static Control's Lanham Act claim. 697 F.3d, at 423. Taking the lay of the land, it identified three competing approaches to determining whether a plaintiff has standing to sue under the Lanham Act. It observed that the Third, Fifth, Eighth, and Eleventh Circuits all refer to "antitrust standing or the [Associated General Contractors] factors in deciding Lanham Act standing," as the District Court had done. Id., at 410 (citing Conte Bros. Automotive, Inc. v. Quaker State-Slick 50, Inc., 165 F.3d 221, 233-234 (C.A.3 1998); Procter & Gamble Co. v. Amway Corp., 242 F.3d 539, 562-563 (C.A.5 2001); Gilbert/Robinson, Inc. v. Carrie Beverage-Missouri, Inc., 989 F.2d 985, 990-991 (C.A.8 1993); Phoenix of Broward, Inc. v. McDonald's Corp., 489 F.3d 1156, 1162-1164 (C.A.11 2007)). By contrast, "[t]he Seventh, Ninth, and Tenth [Circuits] use a categorical test, permitting Lanham Act suits only by an actual competitor." 697 F.3d, at 410 (citing L.S. Heath & Son, Inc. v. AT & T Information Systems, Inc., 9 F.3d 561, 575 (C.A.7 1993); Waits, supra, at 1108-1109; Stanfield v. Osborne Industries, Inc., 52 F.3d 867, 873 (C.A.10 1995)). And the Second Circuit applies a "`reasonable interest' approach," under which a Lanham Act plaintiff "has standing if the claimant can demonstrate `(1) a reasonable interest to be protected against the alleged false advertising and (2) a reasonable basis for believing that the interest is likely to be damaged by the alleged false advertising.'" 697 F.3d, at 410 (quoting Famous Horse, Inc. v. 5th Avenue Photo Inc., 624 F.3d 106, 113 (C.A.2 2010)). The Sixth Circuit applied the Second Circuit's reasonable-interest test and concluded that Static Control had standing because it "alleged a cognizable interest in its business reputation and sales to remanufacturers and sufficiently alleged that th[o]se interests were harmed by Lexmark's statements to the remanufacturers that Static Control was engaging in illegal conduct." 697 F.3d, at 411.

We granted certiorari to decide "the appropriate analytical framework for determining a party's standing to maintain an action for false advertising under the Lanham Act." Pet. for Cert. i; 569 U.S. ___, 133 S.Ct. 2766, 186 L.Ed.2d 217 (2013).2

II. "Prudential Standing"

The parties' briefs treat the question on which we granted certiorari as one of "prudential standing." Because we think that label misleading, we begin by clarifying the nature of the question at issue in this case.

From Article III's limitation of the judicial power to resolving "Cases" and "Controversies," and the separation-of-powers principles underlying that limitation, we have deduced a set of requirements that together make up the "irreducible constitutional minimum of standing." Lujan v. Defenders of Wildlife, 504 U.S. 555, 560, 112 S.Ct. 2130, 119 L.Ed.2d 351 (1992). The plaintiff must have suffered or be imminently threatened with a concrete and particularized "injury in fact" that is fairly traceable to the challenged action of the defendant and likely to be redressed by a favorable judicial decision. Ibid. Lexmark does not deny that Static Control's allegations of lost sales and damage to its business reputation give it standing under Article III to press its falseadvertising claim, and we are satisfied that they do.

Although Static Control's claim thus presents a case or controversy that is properly within federal courts' Article III jurisdiction, Lexmark urges that we should decline to adjudicate Static Control's claim on grounds that are "prudential," rather than constitutional. That request is in some tension with our recent reaffirmation of the principle that "a federal court's `obligation' to hear and decide" cases within its jurisdiction "is `virtually unflagging.'" Sprint Communications, Inc. v. Jacobs, 571 U.S. ___, ___, 134 S.Ct. 584, 591, 187 L.Ed.2d 505 (2013) (quoting Colorado River Water Conservation Dist. v. United States, 424 U.S. 800, 817, 96 S.Ct. 1236, 47 L.Ed.2d 483 (1976)). In recent decades, however, we have adverted to a "prudential" branch of standing, a doctrine not derived from Article III and "not exhaustively defined" but encompassing (we have said) at least three broad principles: "`the general prohibition on a litigant's raising another person's legal rights, the rule barring adjudication of generalized grievances more appropriately addressed in the representative branches, and the requirement that a plaintiff's complaint fall within the zone of interests protected by the law invoked.'" Elk Grove Unified School Dist. v. Newdow, 542 U.S. 1, 12, 124 S.Ct. 2301, 159 L.Ed.2d 98 (2004) (quoting Allen v. Wright, 468 U.S. 737, 751, 104 S.Ct. 3315, 82 L.Ed.2d 556 (1984)).

Lexmark bases its "prudential standing" arguments chiefly on Associated General Contractors, but we did not describe our analysis in that case in those terms. Rather, we sought to "ascertain," as a matter of statutory interpretation, the "scope of the private remedy created by" Congress in § 4 of the Clayton Act, and the "class of persons who [could] maintain a private damages action under" that legislatively conferred cause of action. 459 U.S., at 529, 532, 103 S.Ct. 897. We held that the statute limited the class to plaintiffs whose injuries were proximately caused by a defendant's antitrust violations. Id., at 532-533, 103 S.Ct. 897. Later decisions confirm that Associated General Contractors rested on statutory, not "prudential," considerations. See, e.g., Holmes v. Securities Investor Protection Corporation, 503 U.S. 258, 265-268, 112 S.Ct. 1311, 117 L.Ed.2d 532 (1992) (relying on Associated General Contractors in finding a proximate-cause requirement in the cause of action created by the Racketeer Influenced and Corrupt Organizations Act (RICO), 18 U.S.C. § 1964(c)); Anza v. Ideal Steel Supply Corp., 547 U.S. 451, 456, 126 S.Ct. 1991, 164 L.Ed.2d 720 (2006) (affirming that Holmes "relied on a careful interpretation of § 1964(c)"). Lexmark's arguments thus do not deserve the "prudential" label.

Static Control, on the other hand, argues that we should measure its "prudential standing" by using the zone-ofinterests test. Although we admittedly have placed that test under the "prudential" rubric in the past, see, e.g., Elk Grove, supra, at 12, 124 S.Ct. 2301, it does not belong there any more than Associated General Contractors does. Whether a plaintiff comes within "the `zone of interests'" is an issue that requires us to determine, using traditional tools of statutory interpretation, whether a legislatively conferred cause of action encompasses a particular plaintiff's claim. See Steel Co. v. Citizens for Better Environment, 523 U.S. 83, 97, and n. 2, 118 S.Ct. 1003, 140 L.Ed.2d 210 (1998); Clarke v. Securities Industry Assn., 479 U.S. 388, 394-395, 107 S.Ct. 750, 93 L.Ed.2d 757 (1987); Holmes, supra, at 288, 112 S.Ct. 1311 (SCALIA, J., concurring in judgment). As Judge Silberman of the D.C. Circuit recently observed, "`prudential standing' is a misnomer" as applied to the zone-of-interests analysis, which asks whether "this particular class of persons ha[s] a right to sue under this substantive statute." Association of Battery Recyclers, Inc. v. EPA, 716 F.3d 667, 675-676 (2013) (concurring opinion).3

In sum, the question this case presents is whether Static Control falls within the class of plaintiffs whom Congress has authorized to sue under § 1125(a). In other words, we ask whether Static Control has a cause of action under the statute.4 That question requires us to determine the meaning of the congressionally enacted provision creating a cause of action. In doing so, we apply traditional principles of statutory interpretation. We do not ask whether in our judgment Congress should have authorized Static Control's suit, but whether Congress in fact did so. Just as a court cannot apply its independent policy judgment to recognize a cause of action that Congress has denied, see Alexander v. Sandoval, 532 U.S. 275, 286-287, 121 S.Ct. 1511, 149 L.Ed.2d 517 (2001), it cannot limit a cause of action that Congress has created merely because "prudence" dictates.

III. Static Control's Right To Sue Under § 1125(a)

Thus, this case presents a straightforward question of statutory interpretation: Does the cause of action in § 1125(a) extend to plaintiffs like Static Control? The statute authorizes suit by "any person who believes that he or she is likely to be damaged" by a defendant's false advertising. § 1125(a)(1). Read literally, that broad language might suggest that an action is available to anyone who can satisfy the minimum requirements of Article III. No party makes that argument, however, and the "unlikelihood that Congress meant to allow all factually injured plaintiffs to recover persuades us that [§ 1125(a)] should not get such an expansive reading." Holmes, 503 U.S., at 266, 112 S.Ct. 1311 (footnote omitted). We reach that conclusion in light of two relevant background principles already mentioned: zone of interests and proximate causality.

A. Zone of Interests

First, we presume that a statutory cause of action extends only to plaintiffs whose interests "fall within the zone of interests protected by the law invoked." Allen, 468 U.S., at 751, 104 S.Ct. 3315. The modern "zone of interests" formulation originated in Association of Data Processing Service Organizations, Inc. v. Camp, 397 U.S. 150, 90 S.Ct. 827, 25 L.Ed.2d 184 (1970), as a limitation on the cause of action for judicial review conferred by the Administrative Procedure Act (APA). We have since made clear, however, that it applies to all statutorily created causes of action; that it is a "requirement of general application"; and that Congress is presumed to "legislat[e] against the background of" the zone-of-interests limitation, "which applies unless it is expressly negated." Bennett v. Spear, 520 U.S. 154, 163, 117 S.Ct. 1154, 137 L.Ed.2d 281 (1997); see also Holmes, supra, at 287-288, 112 S.Ct. 1311 (SCALIA, J., concurring in judgment). It is "perhaps more accurat[e]," though not very different as a practical matter, to say that the limitation always applies and is never negated, but that our analysis of certain statutes will show that they protect a more-than-usually "expan[sive]" range of interests. Bennett, supra, at 164, 117 S.Ct. 1154. The zone-of-interests test is therefore an appropriate tool for determining who may invoke the cause of action in § 1125(a).5

We have said, in the APA context, that the test is not "`especially demanding,'" Match-E-Be-Nash-She-Wish Band of Pottawatomi Indians v. Patchak, 567 U.S. ___, ___, 132 S.Ct. 2199, 2210, 183 L.Ed.2d 211 (2012). In that context we have often "conspicuously included the word `arguably' in the test to indicate that the benefit of any doubt goes to the plaintiff," and have said that the test "forecloses suit only when a plaintiff's `interests are so marginally related to or inconsistent with the purposes implicit in the statute that it cannot reasonably be assumed that'" Congress authorized that plaintiff to sue. Id., at ___, 132 S.Ct., at 2210. That lenient approach is an appropriate means of preserving the flexibility of the APA's omnibus judicial-review provision, which permits suit for violations of numerous statutes of varying character that do not themselves include causes of action for judicial review. "We have made clear, however, that the breadth of the zone of interests varies according to the provisions of law at issue, so that what comes within the zone of interests of a statute for purposes of obtaining judicial review of administrative action under the `"generous review provisions"' of the APA may not do so for other purposes." Bennett, supra, at 163, 117 S.Ct. 1154 (quoting Clarke, 479 U.S., at 400, n. 16, 107 S.Ct. 750, in turn quoting Data Processing, supra, at 156, 90 S.Ct. 827).

Identifying the interests protected by the Lanham Act, however, requires no guesswork, since the Act includes an "unusual, and extraordinarily helpful," detailed statement of the statute's purposes. H.B. Halicki Productions v. United Artists Communications, Inc., 812 F.2d 1213, 1214 (C.A.9 1987). Section 45 of the Act, codified at 15 U.S.C. § 1127, provides:

Most of the enumerated purposes are relevant to false-association cases; a typical false-advertising case will implicate only the Act's goal of "protect[ing] persons engaged in [commerce within the control of Congress] against unfair competition." Although "unfair competition" was a "plastic" concept at common law, Ely-Norris Safe Co. v. Mosler Safe Co., 7 F.2d 603, 604 (C.A.2 1925) (L. Hand, J.), it was understood to be concerned with injuries to business reputation and present and future sales. See Rogers, Book Review, 39 Yale L.J. 297, 299 (1929); see generally 3 Restatement of Torts, ch. 35, Introductory Note, pp. 536-537 (1938).

We thus hold that to come within the zone of interests in a suit for false advertising under § 1125(a), a plaintiff must allege an injury to a commercial interest in reputation or sales. A consumer who is hoodwinked into purchasing a disappointing product may well have an injury-in-fact cognizable under Article III, but he cannot invoke the protection of the Lanham Act — a conclusion reached by every Circuit to consider the question. See Colligan v. Activities Club of N. Y., Ltd., 442 F.2d 686, 691-692 (C.A.2 1971); Serbin v. Ziebart Int'l Corp., 11 F.3d 1163, 1177 (C.A.3 1993); Made in the USA Foundation v. Phillips Foods, Inc., 365 F.3d 278, 281 (C.A.4 2004); Procter & Gamble Co., 242 F.3d, at 563-564; Barrus v. Sylvania, 55 F.3d 468, 470 (C.A.9 1995); Phoenix of Broward, 489 F.3d, at 1170. Even a business misled by a supplier into purchasing an inferior product is, like consumers generally, not under the Act's aegis.

B. Proximate Cause

Second, we generally presume that a statutory cause of action is limited to plaintiffs whose injuries are proximately caused by violations of the statute. For centuries, it has been "a well established principle of [the common] law, that in all cases of loss, we are to attribute it to the proximate cause, and not to any remote cause." Waters v. Merchants' Louisville Ins. Co., 11 Pet. 213, 223, 9 S.Ct. 691 (1837); see Holmes, 503 U.S., at 287, 112 S.Ct. 1311 (SCALIA, J., concurring in judgment). That venerable principle reflects the reality that "the judicial remedy cannot encompass every conceivable harm that can be traced to alleged wrongdoing." Associated Gen. Contractors, 459 U.S., at 536, 103 S.Ct. 897. Congress, we assume, is familiar with the common-law rule and does not mean to displace it sub silentio. We have thus construed federal causes of action in a variety of contexts to incorporate a requirement of proximate causation. See, e.g., Dura Pharmaceuticals, Inc. v. Broudo, 544 U.S. 336, 346, 125 S.Ct. 1627, 161 L.Ed.2d 577 (2005) (securities fraud); Holmes, supra, at 268-270, 112 S.Ct. 1311 (RICO); Associated Gen. Contractors, supra, at 529-535, 103 S.Ct. 897 (Clayton Act). No party disputes that it is proper to read § 1125(a) as containing such a requirement, its broad language notwithstanding.

The proximate-cause inquiry is not easy to define, and over the years it has taken various forms; but courts have a great deal of experience applying it, and there is a wealth of precedent for them to draw upon in doing so. See Exxon Co., U.S.A. v. Sofec, Inc., 517 U.S. 830, 838-839, 116 S.Ct. 1813, 135 L.Ed.2d 113 (1996); Pacific Operators Offshore, LLP v. Valladolid, 565 U.S. ___, ___, 132 S.Ct. 680, 692-693, 181 L.Ed.2d 675 (2012) (SCALIA, J., concurring in part and concurring in judgment). Proximate-cause analysis is controlled by the nature of the statutory cause of action. The question it presents is whether the harm alleged has a sufficiently close connection to the conduct the statute prohibits.

Put differently, the proximate-cause requirement generally bars suits for alleged harm that is "too remote" from the defendant's unlawful conduct. That is ordinarily the case if the harm is purely derivative of "misfortunes visited upon a third person by the defendant's acts." Holmes, supra, at 268-269, 112 S.Ct. 1311; see, e.g., Hemi Group, LLC v. City of New York, 559 U.S. 1, 10-11, 130 S.Ct. 983, 175 L.Ed.2d 943 (2010). In a sense, of course, all commercial injuries from false advertising are derivative of those suffered by consumers who are deceived by the advertising; but since the Lanham Act authorizes suit only for commercial injuries, the intervening step of consumer deception is not fatal to the showing of proximate causation required by the statute. See Harold H. Huggins Realty, Inc. v. FNC, Inc., 634 F.3d 787, 800-801 (C.A.5 2011). That is consistent with our recognition that under common-law principles, a plaintiff can be directly injured by a misrepresentation even where "a third party, and not the plaintiff, ... relied on" it. Bridge v. Phoenix Bond & Indemnity Co., 553 U.S. 639, 656, 128 S.Ct. 2131, 170 L.Ed.2d 1012 (2008).

We thus hold that a plaintiff suing under § 1125(a) ordinarily must show economic or reputational injury flowing directly from the deception wrought by the defendant's advertising; and that that occurs when deception of consumers causes them to withhold trade from the plaintiff. That showing is generally not made when the deception produces injuries to a fellow commercial actor that in turn affect the plaintiff. For example, while a competitor who is forced out of business by a defendant's false advertising generally will be able to sue for its losses, the same is not true of the competitor's landlord, its electric company, and other commercial parties who suffer merely as a result of the competitor's "inability to meet [its] financial obligations." Anza, 547 U.S., at 458, 126 S.Ct. 1991.6

C. Proposed Tests

At oral argument, Lexmark agreed that the zone of interests and proximate causation supply the relevant background limitations on suit under § 1125(a). See Tr. of Oral Arg. 4-5, 11-12, 17-18. But it urges us to adopt, as the optimal formulation of those principles, a multifactor balancing test derived from Associated General Contractors. In the alternative, it asks that we adopt a categorical test permitting only direct competitors to sue for false advertising. And although neither party urges adoption of the "reasonable interest" test applied below, several amici do so. While none of those tests is wholly without merit, we decline to adopt any of them. We hold instead that a direct application of the zone-of-interests test and the proximate-cause requirement supplies the relevant limits on who may sue.

The balancing test Lexmark advocates was first articulated by the Third Circuit in Conte Bros. and later adopted by several other Circuits. Conte Bros. identified five relevant considerations:

This approach reflects a commendable effort to give content to an otherwise nebulous inquiry, but we think it slightly off the mark. The first factor can be read as requiring that the plaintiff's injury be within the relevant zone of interests and the second and third as requiring (somewhat redundantly) proximate causation; but it is not correct to treat those requirements, which must be met in every case, as mere factors to be weighed in a balance. And the fourth and fifth factors are themselves problematic. "[T]he difficulty that can arise when a court attempts to ascertain the damages caused by some remote action" is a "motivating principle" behind the proximate-cause requirement, Anza, supra, at 457-458, 126 S.Ct. 1991; but potential difficulty in ascertaining and apportioning damages is not, as Conte Bros. might suggest, an independent basis for denying standing where it is adequately alleged that a defendant's conduct has proximately injured an interest of the plaintiff's that the statute protects. Even when a plaintiff cannot quantify its losses with sufficient certainty to recover damages, it may still be entitled to injunctive relief under § 1116(a) (assuming it can prove a likelihood of future injury) or disgorgement of the defendant's ill-gotten profits under § 1117(a). See TrafficSchool.com, Inc. v. Edriver Inc., 653 F.3d 820, 831 (C.A.9 2011); Johnson & Johnson v. Carter-Wallace, Inc., 631 F.2d 186, 190 (C.A.2 1980). Finally, experience has shown that the Conte Bros. approach, like other open-ended balancing tests, can yield unpredictable and at times arbitrary results. See, e.g., Tushnet, Running the Gamut from A to B: Federal Trademark and False Advertising Law, 159 U. Pa. L.Rev. 1305, 1376-1379 (2011).

In contrast to the multifactor balancing approach, the direct-competitor test provides a bright-line rule; but it does so at the expense of distorting the statutory language. To be sure, a plaintiff who does not compete with the defendant will often have a harder time establishing proximate causation. But a rule categorically prohibiting all suits by noncompetitors would read too much into the Act's reference to "unfair competition" in § 1127. By the time the Lanham Act was adopted, the common-law tort of unfair competition was understood not to be limited to actions between competitors. One leading authority in the field wrote that "there need be no competition in unfair competition," just as "[t]here is no soda in soda water, no grapes in grape fruit, no bread in bread fruit, and a clothes horse is not a horse but is good enough to hang things on." Rogers, 39 Yale L. J., at 299; accord, Vogue Co. v. Thompson-Hudson Co., 300 F. 509, 512 (C.A.6 1924); 1 H. Nims, The Law of Unfair Competition and Trade-Marks, p. vi (4th ed. 1947); 2 id., at 1194-1205. It is thus a mistake to infer that because the Lanham Act treats false advertising as a form of unfair competition, it can protect only the false-advertiser's direct competitors.

Finally, there is the "reasonable interest" test applied by the Sixth Circuit in this case. As typically formulated, it requires a commercial plaintiff to "demonstrate `(1) a reasonable interest to be protected against the alleged false advertising and (2) a reasonable basis for believing that the interest is likely to be damaged by the alleged false advertising.'" 697 F.3d, at 410 (quoting Famous Horse, 624 F.3d, at 113). A purely practical objection to the test is that it lends itself to widely divergent application. Indeed, its vague language can be understood as requiring only the bare minimum of Article III standing. The popularity of the multifactor balancing test reflects its appeal to courts tired of "grappl[ing] with defining" the "`reasonable interest'" test "with greater precision." Conte Bros., 165 F.3d, at 231. The theoretical difficulties with the test are even more substantial: The relevant question is not whether the plaintiff's interest is "reasonable," but whether it is one the Lanham Act protects; and not whether there is a "reasonable basis" for the plaintiff's claim of harm, but whether the harm alleged is proximately tied to the defendant's conduct. In short, we think the principles set forth above will provide clearer and more accurate guidance than the "reasonable interest" test.

IV. Application

Applying those principles to Static Control's false-advertising claim, we conclude that Static Control comes within the class of plaintiffs whom Congress authorized to sue under § 1125(a).

To begin, Static Control's alleged injuries — lost sales and damage to its business reputation — are injuries to precisely the sorts of commercial interests the Act protects. Static Control is suing not as a deceived consumer, but as a "perso[n] engaged in" "commerce within the control of Congress" whose position in the marketplace has been damaged by Lexmark's false advertising. § 1127. There is no doubt that it is within the zone of interests protected by the statute.

Static Control also sufficiently alleged that its injuries were proximately caused by Lexmark's misrepresentations. This case, it is true, does not present the "classic Lanham Act false-advertising claim" in which "`one competito[r] directly injur[es] another by making false statements about his own goods [or the competitor's goods] and thus inducing customers to switch.'" Harold H. Huggins Realty, 634 F.3d, at 799, n. 24. But although diversion of sales to a direct competitor may be the paradigmatic direct injury from false advertising, it is not the only type of injury cognizable under § 1125(a). For at least two reasons, Static Control's allegations satisfy the requirement of proximate causation.

First, Static Control alleged that Lexmark disparaged its business and products by asserting that Static Control's business was illegal. See 697 F.3d, at 411, n. 10 (noting allegation that Lexmark "directly target[ed] Static Control" when it "falsely advertised that Static Control infringed Lexmark's patents"). When a defendant harms a plaintiff's reputation by casting aspersions on its business, the plaintiff's injury flows directly from the audience's belief in the disparaging statements. Courts have therefore afforded relief under § 1125(a) not only where a defendant denigrates a plaintiff's product by name, see, e.g., McNeilab, Inc. v. American Home Prods. Corp., 848 F.2d 34, 38 (C.A.2 1988), but also where the defendant damages the product's reputation by, for example, equating it with an inferior product, see, e.g., Camel Hair and Cashmere Inst. of Am., Inc. v. Associated Dry Goods Corp., 799 F.2d 6, 7-8, 11-12 (C.A.1 1986); PPX Enterprises, Inc. v. Audiofidelity, Inc., 746 F.2d 120, 122, 125 (C.A.2 1984). Traditional proximate-causation principles support those results: As we have observed, a defendant who "`seeks to promote his own interests by telling a known falsehood to or about the plaintiff or his product'" may be said to have proximately caused the plaintiff's harm. Bridge, 553 U.S., at 657, 128 S.Ct. 2131 (quoting Restatement (Second) of Torts § 870, Comment h (1977); emphasis added in Bridge).

The District Court emphasized that Lexmark and Static Control are not direct competitors. But when a party claims reputational injury from disparagement, competition is not required for proximate cause; and that is true even if the defendant's aim was to harm its immediate competitors, and the plaintiff merely suffered collateral damage. Consider two rival carmakers who purchase airbags for their cars from different third-party manufacturers. If the first carmaker, hoping to divert sales from the second, falsely proclaims that the airbags used by the second carmaker are defective, both the second carmaker and its airbag supplier may suffer reputational injury, and their sales may decline as a result. In those circumstances, there is no reason to regard either party's injury as derivative of the other's; each is directly and independently harmed by the attack on its merchandise.

In addition, Static Control adequately alleged proximate causation by alleging that it designed, manufactured, and sold microchips that both (1) were necessary for, and (2) had no other use than, refurbishing Lexmark toner cartridges. See App. 13, ¶ 31; id., at 37, ¶ 54.7 It follows from that allegation that any false advertising that reduced the remanufacturers' business necessarily injured Static Control as well. Taking Static Control's assertions at face value, there is likely to be something very close to a 1:1 relationship between the number of refurbished Prebate cartridges sold (or not sold) by the remanufacturers and the number of Prebate microchips sold (or not sold) by Static Control. "Where the injury alleged is so integral an aspect of the [violation] alleged, there can be no question" that proximate cause is satisfied. Blue Shield of Va. v. McCready, 457 U.S. 465, 479, 102 S.Ct. 2540, 73 L.Ed.2d 149 (1982).

To be sure, on this view, the causal chain linking Static Control's injuries to consumer confusion is not direct, but includes the intervening link of injury to the remanufacturers. Static Control's allegations therefore might not support standing under a strict application of the "`"general tendency"'" not to stretch proximate causation "`"beyond the first step."'" Holmes, 503 U.S., at 271, 112 S.Ct. 1311. But the reason for that general tendency is that there ordinarily is a "discontinuity" between the injury to the direct victim and the injury to the indirect victim, so that the latter is not surely attributable to the former (and thus also to the defendant's conduct), but might instead have resulted from "any number of [other] reasons." Anza, 547 U.S., at 458-459, 126 S.Ct. 1991. That is not the case here. Static Control's allegations suggest that if the remanufacturers sold 10,000 fewer refurbished cartridges because of Lexmark's false advertising, then it would follow more or less automatically that Static Control sold 10,000 fewer microchips for the same reason, without the need for any "speculative ... proceedings" or "intricate, uncertain inquiries." Id., at 459-460, 126 S.Ct. 1991. In these relatively unique circumstances, the remanufacturers are not "more immediate victim[s]" than Static Control. Bridge, supra, at 658, 128 S.Ct. 2131.

Although we conclude that Static Control has alleged an adequate basis to proceed under § 1125(a), it cannot obtain relief without evidence of injury proximately caused by Lexmark's alleged misrepresentations. We hold only that Static Control is entitled to a chance to prove its case.

To invoke the Lanham Act's cause of action for false advertising, a plaintiff must plead (and ultimately prove) an injury to a commercial interest in sales or business reputation proximately caused by the defendant's misrepresentations. Static Control has adequately pleaded both elements. The judgment of the Court of Appeals is affirmed.

It is so ordered.
