The plaintiffs appeal from the entry of summary judgment for the defendants, Philip Morris USA Inc. and its parent company (collectively, “Philip Morris”), on state-law claims based on the marketing of “Light” cigarettes. 1 The district court ruled that these claims were preempted by the Federal Cigarette Labeling and Advertising Act (the “FCLAA”), which provides that “[n]o requirement or prohibition based on smoking and health shall be imposed under State law with respect to the advertising or promotion of any cigarettes the packages of which are labeled in conformity with the provisions of this chapter.” 15 U.S.C. § 1334(b) (1998). Because we find that the claims are not preempted, and because Philip Morris’s alternative arguments for affirmance are also unavailing, we vacate the decision of the district court and remand for further proceedings.
I.
The plaintiffs, who say they have smoked Marlboro Lights for at least fifteen years, claim that Philip Morris has employed unfair and deceptive practices in “designing, manufacturing, promoting, marketing and selling Marlboro Lights and Cambridge Lights purporting to be ‘light’ and having ‘Lowered Tar and Nicotine,’ all while [it] knew those cigarettes would not deliver less tar or nicotine to the consumer.” 2 These brands have rings of ventilation holes in their filters, causing air to mix with the smoke as the smoker draws on the cigarette. As a result, “Lights” register lower levels of tar and nicotine than their so-called “full-flavor” counterparts under a test known as the “Cambridge Filter Method.” This test uses a machine to “smoke” a cigarette, *31 collecting the resulting tar and nicotine in a filter for weighing.
The plaintiffs allege that a person smoking “light” cigarettes, however, engages in unconscious behaviors that essentially negate the ventilation effect, such as taking more frequent, voluminous, or longer puffs, covering the air holes with the lips or the fingers, or smoking additional cigarettes. Due to such “compensation,” which the plaintiffs attribute to the addictive nature of nicotine, they assert that a smoker consumes the same quantities of tar and nicotine from light cigarettes as from full-flavored ones. The plaintiffs explain that the relative levels of these substances bear on a reasonable consumer’s decision on which cigarette to purchase because consumers understand that reducing the quantities of tar and nicotine in cigarettes reduces their adverse health effects. Thus, the plaintiffs allege that Philip Morris has misrepresented material facts by describing its “Lights” as such or as having “lower tar and nicotine,” and that Philip Morris — which was aware of the “compensation” phenomenon before it began marketing its “Lights” brands — did so with the intent to deceive.
The plaintiffs claim that these misrepresentations amount to unfair or deceptive acts or practices in violation of the Maine Unfair Trade Practices Act. 3 Me.Rev.Stat. Ann. tit. 5, § 207 (2002). This statute entitles any person who suffers a loss of money or property as a result of such acts or practices to sue for “actual damages, restitution and for ... other equitable relief.” Id. § 213(1). The plaintiffs have expressly disclaimed any “damages for personal injuries,” but they do seek other relief, including the return of the sums they paid to purchase Marlboro Lights and Cambridge Lights, in addition to punitive damages and the attorneys’ fees as authorized by the Act. 4 The plaintiffs also seek to certify a class of all purchasers of Marlboro Lights or Cambridge Lights in Maine through November 2002.
In response to the plaintiffs’ amended complaint, Philip Morris promptly moved for summary judgment. Philip Morris argued that the plaintiffs’ claims were (1) expressly preempted by the FCLAA, (2) implicitly preempted by “the efforts of Congress and the [Federal Trade Commission] for 40 years to implement a national, uniform policy of informing the public about the health risks of smoking,” and (3) for similar reasons, not cognizable under the Maine Unfair Trade Practices Act, which does not apply to “[transactions or actions otherwise permitted under laws as administered by any regulatory board or officer acting under the statutory authority of the ... United States.” Me.Rev.Stat. Ann. tit. 5, § 208(1).
Each of these arguments relied to some degree on what Philip Morris described as “the FTC’s comprehensive, nationwide program regulating the disclosure of tar and nicotine yields.” In 1959, the then-seven major American cigarette manufacturers had agreed to delete all tar and nicotine claims from their advertising. The FTC subsequently advised them, how *32 ever, “that a factual statement of the tar and nicotine content (expressed in milligrams) of the mainstream smoke from a cigarette would not be in violation ... of any of the provisions of law administered by [the FTC],” provided the statement was “supported by adequate records of tests conducted in accordance with the Cambridge Filter Method.” Press Release, Fed. Trade Comm’n (Mar. 25, 1966). But this advice did not extend to “collateral representations (other than factual statements of tar and nicotine contents of cigarettes offered for sale to the public) ... expressly or by implication, as to reduction or elimination of health hazards.” Id.
Then, in 1967, the FTC itself began using the Cambridge Filter Method to test, inter alia, all cigarette “brands for which any tar or nicotine statement appears on the label or in the advertising ... to determine the accuracy of such statement.” 32 Fed.Reg. 11,178 (Aug. 1, 1967). Though the FTC understood at the time that this method could not “determine the amount of tar and nicotine inhaled by any human smoker,” it was nevertheless adopted to produce results “based on a reasonable standardized method” which were “capable of being presented to the public in a manner that is readily understandable.” Press Release, Fed. Trade Comm’n, FTC to Begin Cigarette Testing (Aug. 1, 1967). The FTC agreed to report the test results to Congress periodically in order to ensure their dissemination to the smoking public, and made the first such report in late 1967.
The FTC subsequently proposed a rule requiring cigarette manufacturers “to disclose, clearly and prominently, in all advertising[,] the tar and nicotine content of the advertised variety ... based on the most recently published [FTC] test results.” 35 Fed.Reg. 12,671 (Aug. 8, 1970). But the rulemaking process was suspended when a consortium of cigarette manufacturers, including Philip Morris, reached an agreement with the FTC on a “voluntary program” to like effect. Letter from Horace R. Kornegay, President, The Tobacco Institute, Inc., to Fed. Trade Comm’n (Dec. 17, 1970). By agreeing to the program, however, the manufacturers did not “admit that the failure affirmatively to disclose” the test results in their advertising “constitutes a violation of law,” or even that the FTC had the authority to enact the proposed rule. Id. The FTC, for its part, took the position that it “retained the unconditional right to reschedule the ... Rule proceeding and to take any other action relating to this subject at any time....” 36 Fed.Reg. 784 (Jan. 16,1971).
Since then, the FTC has neither resumed the rulemaking proceedings suspended by its agreement with the cigarette manufacturers, nor promulgated any formal rule requiring them to disclose the tar or nicotine content of their products. In 1987, the FTC stopped conducting its own tests of cigarettes. The testing continued, however, under the auspices of the Tobacco Institute Testing Laboratory, operated by the major American cigarette manufacturers. 5 The manufacturers agreed to allow the FTC to monitor the lab’s procedures, which included the use of the Cambridge Filter Method. The FTC has obtained the test results from the individual manufacturers through its compulsory process authority, see 15 U.S.C. § 46(b), and reported those results to Congress for each year through 1998. 6
*33 Based on this regime, Philip Morris characterized the lawsuit as “a challenge to the FTC’s regulatory scheme,” because “terms like ‘light’ and ‘lowered tar’ ... convey precisely the same comparative information” as the tar and nicotine measurements derived from testing under the Cambridge Filter Method. The district court agreed, reasoning that
To respond to Plaintiffs’ claims, Philip Morris would have to tell the public that the FTC Method test, though accurate in the laboratory, was inaccurate in real life, and that light cigarette smokers ... infused greater amounts of nicotine and tar than the designation ‘Lights’ and ‘Lowered Tar and Nicotine’ would imply. But, this information, if conveyed through a form of advertising, would run head first into ... the comprehensive federal scheme governing the advertising and promotion of cigarettes.
II.
The plaintiffs challenge the ruling below as at odds with
Cipollone v. Liggett Group, Inc.,
A.
“A fundamental tenet of our federalist system is that constitutionally enacted federal law is supreme to state law. As a result, federal law sometimes preempts state law either expressly or by implication.”
N.H. Motor Transport Ass’n v. Rowe,
1.
As noted at the outset, the FCLAA’s preemption clause states that “[n]o requirement or prohibition based on smoking and health shall be imposed under State law with respect to the advertising or promotion of any cigarettes the packages of which are labeled in conformity with the provisions of this chapter.” 15 U.S.C. § 1334(b). Those provisions mandate that the packages of all cigarettes sold in the United States — and, in general, their advertisements — bear one of a rotating series of labels warning about the adverse health effects of smoking. 8 Id. §§ 1333(a), (c). But no additional “statement relating to smoking and health ... shall be required on any cigarette package.” Id. § 1334(a). The FCLAA also bans cigarette advertising “on any medium of electronic communication subject to the jurisdiction of the Federal Communications Commission,” id. § 1335, and preserves the authority of the FTC over “unfair or deceptive acts or practices in the advertising of cigarettes,” id. § 1336.
These provisions were added to the FCLAA through the Public Health Cigarette Smoking Act of 1969, Pub.L. 91-222, 84 Stat. 87-90, enacted as the restrictions on cigarette advertising contained in the prior version of the FCLAA were set to expire. Pub.L. 89-92 § 10, 79 Stat. 282, 285 (1965). As the expiration date approached, both federal and state authorities prepared to resume their efforts to regulate cigarette advertising.
See Cipollone,
to establish a comprehensive Federal program to deal with cigarette labeling and advertising with respect to any relationship between smoking and health, whereby—
(1) the public may be adequately informed about any adverse health effects of cigarette smoking by inclusion of warning notices on each package of cigarettes and in each advertisement of cigarettes; and
(2) commerce and the national economy may be (A) protected to the maximum extent consistent with this declared policy and (B) not impeded by diverse, nonuniform, and confusing cigarette labeling and advertising regulations with respect to any relationship between smoking and health.
15 U.S.C. § 1331.
With these purposes in mind, the
Cipol-lone
Court considered whether the FCLAA’s preemption clause barred a state-law suit for damages brought by a smoker who had allegedly developed lung cancer from the defendants’ cigarettes.
A plurality of the Court disagreed with this analysis, holding that “the pre-emptive scope of the [FCLAA] is governed entirely by the express language in [§ 1334(b) ],”
id.,
which did, in fact, reach some common law actions.
Id.
at 521-23,
ask whether the legal duty that is the predicate of the common-law damages action constitutes a “requirement or prohibition based on smoking or health ... imposed under State law with respect to advertising or promotion,” giving that clause a fair but narrow reading.... [E]ach phrase within that clause limits the universe of common-law claims preempted by the statute.
Id.
at 524,
The plurality proceeded to consider the smoker’s two theories of fraudulent misrepresentation. The first, that the defendants, “through their advertising, neutralized the effect of federally mandated warning labels,” was preempted by the FCLAA.
Id.
at 527,
But the plurality reached a different conclusion as to the smoker’s second fraudulent misrepresentation theory: “intentional fraud and false misrepresentation both by false misrepresentation of a material fact and by concealment of a material fact.” Id. (internal quotation marks and bracketing omitted). First, the plurality held that the FCLAA does not preempt fraudulent concealment claims that “rely on a state-law duty to disclose such facts through channels of communication other than advertising or promotion,” e.g., in the case of a state law requiring cigarette manufacturers “to disclose material facts about smoking and health to an administrative agency.” Id. Second, the plurality held that
fraudulent-misrepresentation claims that do arise with respect to advertising and promotion (most notably claims based on allegedly false statements of material fact made in advertisements) are not *36 pre-empted by [§ 1334(b) ]. Such claims are predicated not on a duty “based on smoking and health” but rather on a more general obligation-the duty not to deceive.
Id.
at 528-29,
This analysis of the FCLAA’s effect on the smoker’s claims held sway with only four of the Court’s nine Justices. Two others joined Justice Blackmun’s opinion that the FCLAA did not preempt
any
common law claims for damages,
id.
at 531,
2.
The parties agree that whether the FCLAA expressly preempts the plaintiffs’ claims depends on how best to categorize them by analogy to the various causes of action considered in
Cipollone.
In doing so, as the district court recognized,
The plaintiffs seek relief under the Maine Unfair Trade Practices Act, which, in relevant part, outlaws “unfair or deceptive acts or practices in the conduct of any trade or commerce.” Me.Rev.Stat. Ann. tit. 5, § 207. Though this prohibition encompasses various kinds of behavior, including “a material representation, omission, act or practice that is likely to mislead consumers acting reasonably under the circumstances,”
Maine v. Weinschenk,
While the district court stopped short of assigning a specific label to the plaintiffs’ claims, its reasoning suggests that it considered them analogous to the failure-to-warn theory held preempted by
Cipollone.
The court opined that the plaintiffs had failed in them “valiant attempt to tailor their claims to fit within the
Cipollone
exception for violations of the duty not to deceive-”
We differ with the district court’s view of the fit between the plaintiffs’ theory and the
Cipollone
taxonomy and, more fundamentally, of
Cipollone
itself. To start, we do not read
Cipollone
to hold that the FCLAA preempts claims “grounded on [a defendant’s] ‘advertising or promotion of ... cigarettes labeled in conformity with the provisions of federal law and regulation,” as the district court ultimately explained its conclusion.
Nor is a claim preempted merely because it arises out of the adverse health consequences of such cigarettes, as both the reasoning and the result in
Cipollone
make clear. There, in fact, all of the plaintiffs claims were “based on smoking and health” in the sense that they “alleged that [she] developed lung cancer because she smoked cigarettes,”
Furthermore, unlike Philip Morris, we do not read the Court’s subsequent decision in
Reilly
to suggest that the statute’s preemptive effect on a claim depends on the claim’s connection with “smoking and health.” In
Reilly,
the Court held that § 1334(b) preempted regulations on tobacco advertising promulgated by the Massachusetts Attorney General pursuant to his authority under that state’s counterpart to the Maine Unfair Trade Practices Act, Mass. Gen. Laws ch. 93A.
Philip Morris urges us to draw an analogy between the regulations found preempted in
Reilly
and the claims of the plaintiffs here, arguing that, in either case, a state consumer protection act is used “to create requirements or prohibitions regarding advertisements and promotions that are intertwined with the concern about cigarette smoking and health” (internal quotation marks omitted). But this argument again confuses the claim at hand with its predicate state-law duty as the relevant “re
*39
quirement or prohibition” under § 1334(b). The plaintiffs’ claims are indeed “intertwined with the concern about cigarette smoking and health,” just as surely as the regulations in
Reilly
were; the difference, however, is that those regulations were themselves the “prohibitions,” while the prohibition here is the ban on “unfair or deceptive acts or practices in the conduct of any trade or commerce” under the Maine Unfair Trade Practices Act. And
Cipollone,
as we have noted, treats a state-law “duty not to deceive” as broader than a “duty ‘based on smoking and health’” and therefore beyond the reach of FCLAA preemption.
We see nothing in
Reilly
suggesting any intent to disturb this aspect of the
Cipol-lone
plurality holding.
12
Nor do we see any internal inconsistency in the view that the phrase “based on smoking and health” includes state-law prohibitions on cigarette ads targeting youths,
Reilly,
Because the state-law “duty not to deceive” is one such “more general obligation,” it falls within Cipollone’s express holding that “claims based on allegedly false statements of material fact made in advertisements” survive FCLAA preemption.
The district court saw the plaintiffs’ case differently, observing that “[o]ther than these descriptors” (ie., the “light” and “lower tar and nicotine” claims) “the record here is devoid of any
affimative
misstatement.”
First, we question the conclusion that, although the descriptors are themselves characterized as affirmative misstatements, they cannot ground a fraudulent misrepresentation claim left unscathed by Cipollone’s reading of the FCLAA. The district court appears to have based its conclusion on its understanding that, despite the popularity of the terms “light” and “lower tar and nicotine” in cigarette advertising, “Congress and the FTC never acted to restrict the tobacco companies from using these general descriptors.”
Cipollone
arrived at this interpretation in part because, in the FCLAA, “Congress offered no sign that it wished to insulate cigarette manufacturers from longstanding rules governing fraud.”
Id.
at 529,
Second,
Cipollone
does not appear to treat claims based on “implied” as opposed to “express” misrepresentations differently for purposes of FCLAA preemption. Under general principles of tort law, either an express or an implied statement can give rise to a claim for fraudulent misrepresentation.
See Restatement (Second) of Torts
§ 526(c) (1977);
accord Est. of Whit-lock,
Cipollone
does set up a dichotomy between fraud “by false representation of a material fact,”- on one hand, and “by concealment of a material fact,” on the other.
Philip Morris nevertheless insists that this theory amounts to a preempted failure-to-warn claim, “[bjecause any false impression that the descriptors allegedly created would have been eliminated if [Philip Morris] had provided additional health information regarding compensation,” that is, a smoker’s tendency to take in the same harmful quantities of tar and nicotine from light cigarettes as from regular ones. We accept, for present purposes, that the plaintiffs could not claim to have been defrauded by the statements “light” and “lower tar and nicotine” in Philip Morris’s advertising and promotion if they were accompanied by a specific warning about compensation. And we agree that, if the plaintiffs were claiming that the failure to give such a warning through those media was a breach of Philip Morris’s duty under Maine law, the FCLAA would preempt that claim as “rely[ing] on a state-law requirement or prohibition with respect to advertising or promotion.”
Cipollone,
The fact that these alleged misrepresentations were unaccompanied by additional statements in the nature of a warning does not transform the claimed fraud into failure to warn. Indeed, we have trouble imagining any misrepresentation claim wholly independent of what else the defendant said or did not say, given the “well-established principle that a statement or omission must be considered in context, so that accompanying statements may render it immaterial as a matter of law.”
In re Donald J. Trump Casino Sec. Litig.,
*43
Moreover,
Cipollone
itself conceived of failure-to-warn claims much more narrowly than Philip Morris does, describing them to
“require a showing
that ... advertising or promotions should have included additional, or more clearly stated warnings.”
Id.
at 524,
For the same reason, we do not see the plaintiffs’ claims as embracing a preempted warning neutralization theory. Warning neutralization is a species of products liability claim based on conduct by the manufacturer tending to dilute what might otherwise serve as an effective warning of the dangers of its product.
See, e.g., McNeil v. Wyeth,
The plaintiffs here, however, do not allege that the statements “light” and “lower
*44
tar and nicotine” diluted the warnings on Philip Morris’s packaging or advertising so as to make its cigarettes unreasonably dangerous or otherwise defective. Instead, the plaintiffs allege that the statements deceived them into purchasing Marlboro Lights and Cambridge Lights. The presence of the warnings may have some bearing on the materiality of these statements, as just discussed, but that possibility does not change the plaintiffs’ case from one about the statements into one about the warnings. As one court has put it, because “[a]ny statement, even affirmatively false misrepresentations about the health effects of smoking, may have some neutralizing effect on the package warning ..., the concept of neutralization could preempt virtually all affirmative .fraud claims” if viewed as expansively as Philip Morris urges.
Whiteley,
We acknowledge that the Fifth Circuit came to the opposite conclusion in
Brown,
ruling that fraudulent misrepresentation claims arising out of the statements “light” and “Lowered Tar and Nicotine” are in effect warning neutralization claims preempted by § 1334(b).
In line with our earlier discussion, however, we do not see anything in Cipollone’s discussion of warning neutralization claims that equates them with “implied misrepresentation” claims as
Brown
does.
18
We appreciate that the statements “light” and “lower tar and nicotine” could support a warning neutralization claim, ie., by suggesting that those brands of cigarettes do not pose the same grave threats to health announced in the accompanying warning label.
See, e.g., Maize v. Atl. Ref. Co.,
Of course, plaintiffs who elect to proceed on a non-preempted fraudulent misrepresentation theory must eventually prove each of the elements of that cause of action if they are to prevail, including that the challenged representations are indeed false. But, unlike the court in
Brown,
we do not believe that a plaintiffs chance of proving his claim plays any role in determining whether it is preempted by the FCLAA. In rejecting the plaintiffs’ characterization of their claim as sounding in fraud,
Brown
concluded that “[t]he terms ‘light’ and ‘Lowered Tar and Nicotine’ cannot ... be inherently deceptive or untrue,” because the cigarettes in question “do deliver less tar and nicotine as measured by the only government-sanctioned methodology for them measurement,”
ie.,
the Cambridge Filter Method.
We think this approach puts the cart before the horse. The assertion that Marlboro Lights and Cambridge Lights rate lower in tar and nicotine than their full-flavored cousins according to the Cambridge Filter Method may ultimately affect whether the plaintiffs can show that the challenged statements are false.
Cf. Schwab,
Under
Cipollone,
whether § 1334(b) expressly preempts a particular claim depends on “whether the legal duty that is the predicate of the common-law damages action constitutes a requirement or prohi
*46
bition based on smoking or health ... imposed under State law with respect to advertising or promotion,”
Finally, Philip Morris argues that, because “the standards for finding liability under consumer protection acts around the country vary widely,” allowing the plaintiffs’ claims to survive preemption will undermine the FCLAA’s goal of protecting manufacturers from “diverse, nonuniform, and confusing cigarette labeling and advertising regulations with respect to any relationship between smoking and health.” 15 U.S.C. § 1331(2). This is not an imaginary concern. As we have explained, however, fraudulent misrepresentation claims, even if brought under the aegis of a state consumer protection act, are not premised on “regulations with respect to any relationship between smoking and health.” They are premised on “longstanding rules governing fraud,” which themselves arise not from any duty based on smoking and health, but on a duty not to deceive.
Cipollone,
Of course,
Cipollone
further reasoned that § 1334(b) does not encompass fraudulent misrepresentation claims because they “rely only on a single, uniform standard: falsity” and therefore “do not create diverse, nonuniform and confusing standards.”
Id.
at 529,
B.
Philip Morris also challenges the plaintiffs’ claims as impliedly preempted by federal law. Even in the absence of express preemptive language' — -which the FCLAA contains, but which we have concluded does not reach the claims in this case — federal law can preempt state law by implication in two other ways.
See, e.g., California v. ARC Am. Corp.,
Philip Morris does not argue that either Congress or the FTC has evinced an intent to occupy the entire field of cigarette advertising, or even the narrower field of low-tar cigarette advertising. Nor does Philip Morris protest that complying with both the state law the plaintiffs say has been violated and some contrary federal law would be impossible. Instead, Philip Morris maintains that the “[plaintiffs’ claims conflict with the FTC’s 40-year history of regulation and control over the development, testing and marketing of low tar cigarettes, as well as the reporting of tar and nicotine measurements pursuant to the FTC Method and the use of descriptors substantiated by those measurements.” Because Philip Morris has limited its implied preemption argument to the so-called “frustration-of-purpose” theory,
see Geier v. Am. Honda Motor Co.,
In identifying those objectives, Philip Morris argues that “Congress and the FTC have both sought
uniform,
national standards for cigarette advertising with respect to smoking and health. And State-law actions like this one would create a different standard of deceptiveness that would plainly conflict with these goals.” At the outset, we reject the notion that the plaintiffs’ claims would interfere with any congressional designs on cigarette advertising.
21
It is true that, in the FCLAA,
*48
“Congress prohibited state cigarette advertising regulations motivated by concerns about smoking and health.”
Reilly,
In any event, both the Supreme Court and this one have squarely held that the FCLAA has no preemptive force beyond the language of § 1334(b) itself.
Cipol-lone,
as we have noted, overturned the ruling of the court of appeals “that Congress had impliedly pre-empted [the plaintiffs] claims challenging the adequacy of warnings on labels or in advertising or the propriety of [the defendants’] advertising and promotional activities,” holding instead that “the pre-emptive scope of the [FCLAA] is governed entirely by the express language in [§ 1334(b) ].”
In declining to imply a preemptive effect from the FCLAA,
Cipollone
reasoned that “[w]hen Congress has considered the issue of pre-emption and has included in the enacted legislation a provision explicitly addressing that issue, and when that provision provides a reliable indicium of congressional intent with respect to state authority, there is no need to infer congressional intent to pre-empt state laws from the substantive provisions of the legislation.”
By the time we decided
Harshbarger,
however, the Supreme Court had already made clear in
Freightliner
that “[a]t best,
Cipollone
supports an inference that an express pre-emption clause forecloses implied pre-emption; it does not establish a rule.”
Given this alternative basis for
Cipol-
lone’s holding that the FCLAA does not implicitly preempt state-law claims arising out of cigarette advertisements or promotions, it remains good law regardless of what the Court has since said, in other contexts, about the effect of express preemption clauses on implied preemption. Furthermore, we see nothing in either
Geier
or
Sprietsma
— which, like
Freight-liner,
did not consider the preemptive effect of the FCLAA, but other federal statutes with express preemption provisions— suggesting that the
Cipollone
Court was wrong to draw an inference against implied preemption of state-law challenges to cigarette advertising from the presence of an express preemption provision
in the FCLAA,
as opposed to those other statutes. Just as in
Harshbarger,
then, “[w]e are bound by the
Cipollone
majority’s holding that § 1334(b) governs the preemptive scope of the FCLAA” and, therefore, “we are not at liberty to address any implied preemption theories” premised on the statute.
In brief, the FTC Act prohibits “unfair or deceptive acts or practices in or affecting commerce,” 15 U.S.C. § 45(a), and empowers the Commission both to define and enforce that .prohibition in a number of ways relevant here. The Commission may prescribe either informal “interpretive rules and general statements of policy with respect to unfair or deceptive acts or practices,” id. § 57a(a)(l)(A), or, pursuant to notice-and-comment procedures, see id. §§ 57a(b)-(e), formal rules which define those acts and practices “with specificity,” id. § 57a(a)(l)(B). In addition, the Commission may issue cease-and-desist orders against those engaged in violations of the Act. Id. § 45(b). The FTC may enforce such orders — as well as its formal rules— by suing violators for either civil penalties, id. § 45(m), or “such relief as the court finds necessary to redress injuries to con *50 sumers” or other injured parties, id. §§ 57b(a),(b).
The FTC has regularly trained these powers on tar and nicotine claims in cigarette advertising; as the district court observed, “the tobacco industry is hardly unregulated in what it says to consumers about its products, including light cigarettes.”
As we have discussed, the FTC advised the tobacco industry in 1966 that it could make “factual statements” of tar and nicotine content, so long as they “were supported by adequate records of tests conducted in accordance with the Cambridge Filter Method.” Press Release, Fed. Trade Comm’n (Mar. 25, 1966). The FTC soon began to assess such claims by conducting its own tests of cigarettes under the method, and proposed a formal rule requiring cigarette manufacturers to disclose the results of those tests in their advertisements. The proposal was put on hold, however, when the manufacturers agreed to make those disclosures voluntarily.
Before entering into this agreement, the FTC had sought a cease-and-desist order against The American Tobacco Company, charging that ads for certain brands of its cigarettes deceitfully created the impression that they were “low in tar” when they in fact contained more tar than the average brand per then-current FTC test results. This charge was resolved through a 1971 consent order forbidding American from “advertising that any cigarette manufactured by it, or the smoke therefrom, is low or lower in ‘tar’ by use of the words ‘low,’ ‘lower,’ or ‘reduced’ or like qualifying terms, unless the statement is accompanied by a clear and conspicuous disclosure of the ‘tar’ and nicotine content in milligrams in the smoke produced by the advertised cigarette.”
In re Am. Brands,
*51
Inc.,
Based principally on these exercises of authority over tar and nicotine claims, Philip Morris argues that the FTC has expressed a “policy of allowing their use so long as substantiated with the FTC Method numerical results and requiring publication of those results in all brand advertisements.” Because the plaintiffs’ claims “stand[] as an obstacle” to this policy, Philip Morris continues, they are implicitly preempted. Like the plaintiffs, we see a number of problems with this argument.
First, since its 1969 agreement with the tobacco companies, the FTC has never issued a formal rule specifically defining which cigarette advertising practices violate the Act and which do not. As the plaintiffs point out, there is some authority for the proposition that “[s]tate prohibitions of unfair and deceptive practices are not preempted unless they conflict with an express FTC rule.”
United States v. Philip Morris, Inc.,
Unlike many other exercises of agency authority, formal rulemaking comes with a host of procedural protections under the Administrative Procedure Act (“APA”), such as notice of the proposed rule, an opportunity for interested parties to participate, a statement of the basis and purpose of any rule adopted, and its publication ih the Federal Register. 5 U.S.C. § 533 (2007). Limiting the preemptive power of federal agencies to exercises of formal rulemaking authority, then, ensures that the states will have enjoyed these protections before suffering the displacement of their laws.
See, e.g., Wabash Valley Power Ass’n,
Second, apart from the likely import of its rulemaking provisions, the FTC Act raises an additional hurdle to Philip Morris’s implied preemption theory, at least insofar as that theory relies on the 1971 and 1995 consent orders. The Act states that “[rjemedies provided in [15 U.S.C. § 57b] are in addition to, and not in lieu of, any other remedy or right of action provided by State or Federal law.” 15 U.S.C. § 57b(e). And § 57b, as we have observed, empowers the Commission to sue for relief on behalf of consumers against those who violate its cease-and-desist orders against unfair or deceptive acts or practices. We do not think it a stretch, then, to say that when the FTC merely issues such an order, but never uses it as the basis for a subsequent lawsuit, the order does not supplant state-law rights of action any more than the lawsuit would have. A number of authorities have reached the same conclusion, though not necessarily by way of the same rationale.
See California v. Am. Stores Co.,
Relying on the Supreme Court’s decision in
Geier,
Philip Morris argues that § 57b(e), which it calls a “savings clause,” “does
not
bar the ordinary working of conflict pre-emption principles.”
But unlike the savings clause of the NTMVSA, § 57b(e) does not speak of compliance with a federal standard as a defense to a state-law claim, leaving open the possibility of a preemptive conflict between the standard and the claim. Instead, § 57b(e) specifically provides that state-law rights of action survive the FTC’s efforts at judicial enforcement of its own federal standards: in other words, that those efforts are “in addition to, and not in lieu of’ other available remedies. We can think of no other purpose for this clause other than to allow further relief from
*53
unfair or deceptive acts or practices under state law even after the Commission has already challenged them through litigation under the FTC Act, and Philip Morris does not suggest any.
Cf. Geier,
This reading of § 57b(e), moreover, does nothing to diminish the FTC’s power to preempt state law through other assertions of its authority. After entering into a consent order, for example, the Commission remains free to adopt its terms as a formal rule, 15 U.S.C. § 57a(b)(l); as we have discussed, this process affords states and other interested parties with the kinds of procedural protections usually deemed essential to regulatory preemption.
See, e.g., Wabash Valley Power Ass’n,
Third, as the one court squarely holding that FTC consent orders can preempt state law has recognized, the mere entry of such an order dealing with a particular practice “is insufficient to preclude supplemental state regulation.” Gen. Motors Corp., 897 F.2d at" 39. Thus, even if we were to agree that FTC action short of formal rulemaking — including consent orders — can implicitly preempt state law in some cases; we do not think that this is one of them, because the plaintiffs’ state-law claims do not pose a threat to any federal regulatory objectives apparent in the FTC’s approach to tar and nicotine claims in cigarette advertising.
Though Philip Morris argues that FTC policy permits a manufacturer to make such claims so long as they are consistent with the results of testing under the Cambridge Filter Method and those results are disclosed in the manufacturer’s advertising, the Commission has on occasion challenged statements about the tar or nicotine content of a particular brand even though they were supported by such testing. In 1982, for example, the FTC told a cigarette manufacturer that it could not rely on the Cambridge Filter Method to substantiate claims that one of its brands had only 1 milligram of tar, because the method did not accurately measure the tar and nicotine content of that brand due to its unusual filter design.
See FTC v. Brown & Williamson Tobacco Corp.,
The FTC, then, has not invariably allowed tar and nicotine claims that are supported by the Cambridge Filter Method, but has recognized that such claims may nevertheless amount to unfair or deceptive acts or practices in certain circumstances. We acknowledge that the claim at issue here — that Marlboro and Cambridge Lights have “lower tar and nicotine” than their full-flavored versions — differs from those the FTC has challenged in the past, but our task is not to decide whether the FTC would view a particular kind of tar and nicotine claim as a violation of the FTC Act.
27
Instead, we must determine whether the FTC’s oversight of such claims “convey[s] an authoritative message of a federal policy” jeopardized by the plaintiffs’ common-law damages action.
Sprietsma,
We derive additional support for this conclusion from
Geier
and Sprietsma.

Geier
ruled that a state-law tort action alleging that the defendant had negligently designed the plaintiffs 1987 car without airbags would frustrate the purpose of a federal regulation “requiring] auto manufacturers to equip some but not all of their 1987 vehicles with” such devices.
Geier
and
Sprietsma,
then, teach that it is not the fact of agency action on a particular subject alone — -but the reasons for the action — that control its preemptive effect. And here, no clear rationale emerges from the history of the FTC’s treatment of tar and nicotine claims; indeed, the parties point to conflicting statements by the Commission itself on whether it even has an official position on the definitions of the terms “light” and “lower tar and nicotine.”
Compare, e.g.,
62 Fed.Reg. 48,158, 48,163 (Sept. 12, 1997) (“There are no official definitions for these terms”)
with, e.g.,
1980 FTC
Rep. to Congress
18 n. 11 (“The FTC has not defined ... any term related to tar level except for ‘low “tar” ’, which the FTC defines as 15.0 mg or less ‘tar.’ ”). Moreover, as in
Sprietsma
and in contrast to
Geier,
the Solicitor General recently filed a brief in the Supreme Court explaining that the FTC “has never promulgated definitions of terms such as ‘light’ and ‘low tar’ ” and that its previous statements purporting to define them “did not reflect an official regulatory position.” Br. for United States as Amicus Curiae Supporting Petitioners,
Watson v. Philip Morris Cos.,
— U.S. -,
C.
Finally, Philip Morris argues that its challenged advertising practices constitute “[transactions or actions otherwise permitted under laws as administered by any regulatory board or officer acting under the statutory authority of the United States” and, as such, are excepted from the Maine Unfair Trade Practices Act. Me. Rev.Stat. Ann. tit. 5, § 208(1). This argument, like Philip Morris’s implied preemption theory, depends largely on its characterization of FTC policy to allow the use of the terms “light” and “lower tar and nicotine” when supported by testing under the Cambridge Filter Method. And, as we have explained, we disagree with that characterization: the full history of the FTC’s oversight of tar and nicotine claims
*56
reveals its view that, depending on the circumstances, those claims can be unfair or deceptive notwithstanding their support in Cambridge Filter Method test results.
See, e.g., Brown & Williamson Tobacco Corp.,
We disagree, then, with those courts holding that the FTC has “authorized” Philip Morris’s “light” and “lower tar and nicotine” claims so as to put them beyond the reach of state consumer protection statutes with exceptions similar to Maine’s.
See Flanagan v. Altria Group, Inc.,
No. 05-71697,
The court in
Price,
for example, concluded that the FTC, through its 1971 and 1995 consent orders with American Tobacco, “could, and did, specifically authorize all United States tobacco companies to utilize the terms ‘low,’ ‘lower,’ ‘reduced’ or like qualifying terms such as ‘light’ so long as the descriptive terms are accompanied by a clear and conspicuous disclosure of the ‘tar’ and nicotine content in milligrams of the smoke produced by the advertised cigarette.”
Furthermore, even if the consent decrees did “authorize” particular tar and nicotine claims for purposes of state consumer protection laws, that authorization does not appear to extend to the claims at issue here. Insofar as the 1971 consent decree permits “use of the words ‘low,’ ‘lower,’ or ‘reduced’ or like qualifying terms,” it does so only if “the statement is accompanied by a clear and conspicuous disclosure of the ‘tar’ and nicotine content in milligrams in the smoke produced by the advertised cigarette” per the Cambridge Filter Method.
In re Am. Brands, Inc.,
We see at least two weaknesses in this position. First, as we have noted, the FCLAA also provides that “[n]othing in this chapter (other than the requirements of [15 U.S.C. § 1333]) shall be construed to limit, restrict, expand, or otherwise affect the authority of the [FTC] with respect to unfair or deceptive acts or practices in the advertising of cigarettes.” 15 U.S.C. § 1336. So it is at least arguable that the restriction on additional health-related statements in the FCLAA does not apply to the FTC.
See FDA v. Brown & Williamson Tobacco Corp.,
We do not mean to suggest that the consent orders have no bearing at all on whether Philip Morris’s use of the terms “light” and “Lowered Tar and Nicotine” violates the Maine Unfair Trade Practices Act. Indeed, the Act provides that, in construing its ban on unfair or deceptive acts or practices, “courts will be guided by the interpretations given by the Federal Trade Commission and the Federal Courts to [15 U.S.C. § 45(a)(1) ], as from time to time amended.” Me.Rev.Stat. Ann. tit. 5, § 207;
see, e.g., Searles v. Fleetwood Homes of Pa., Inc.,
Finally, in an echo of its implied preemption argument, Philip Morris posits that, even if the consent orders did not authorize the tar and nicotine claims at *58 issue here, the FTC’s “comprehensive, detailed regulation of cigarette advertising and promotion” suffices to exempt them from the Maine Unfair Trade Practices Act (internal quotation marks omitted). The Act, however, exempts “[t]ransactions or actions otherwise permitted ” (emphasis added), not “otherwise regulated.” Cf. Mary Dee Pridgen, Consumer Protection and the Law § 4:32 (1986 & 2006 supp.) (contrasting consumer protection statutes exempting “actions or transactions otherwise ... regulated” with those exempting “only those activities ‘permitted’ ”).
Unlike Philip Morris, we do not believe that the Maine Supreme Judicial Court equated these two concepts in
First of Maine Commodities v. Dube,
We read
First of Maine Commodities,
then, for the proposition that conduct is exempt from the Unfair Trade Practices Act where it is subject to specific standards left to the enforcement of an administrative agency, not merely those circumstances in which the agency’s regulatory scheme is generally “extensive” or “detailed.”
See also Weinschenk,
III.
In summary, we conclude that the plaintiffs’ claims that Philip Morris has made fraudulent misrepresentations in violation of the Maine Unfair Trade Practices Act by advertising and promoting Marlboro and Cambridge Lights as “light” and having “Lowered Tar and Nicotine” are not (1) expressly preempted by the FCLAA, (2) implicitly preempted, either by the FCLAA or by the FTC’s oversight of tar and nicotine claims in cigarette advertising, or (3) barred by the Act’s exemption for “transactions or actions otherwise permitted.” We do not, of course, reach any conclusion on the merits of the plaintiffs’ claims, the availability of summary judgment on other grounds, or the force of or any other defense potentially available to
*59
Philip Morris; and nothing in what we have said should be construed as expressing any views on those issues that are not before us. As always, “we leave the extent and nature of further proceedings in the hands of the district court.”
Patterson v. Patterson,
So ordered.
Notes
. The parent company, Altria Group, Inc., did not join in the summary judgment motion, seeking to preserve a defense based on lack of personal jurisdiction. Nevertheless, the district court observed that "the parties acknowledged as a practical matter that the Court's ruling would be equally applicable to Altria.”
. Philip Morris's expert witness, in his affidavit submitted in support of its motion for summary judgment, explained that "[t]he terms 'light[s]’ and ‘low tar' are generally viewed as interchangeable” and that, since the early 1970s, "light” has been "associated with both lighter taste and low tar.”
. The amended complaint also alleges that Philip Morris manipulated the design of its light cigarettes "to register Lowered Tar and Nicotine levels under machine testing conditions while actually delivering higher levels of these compounds when smoked by consumers. ...” The plaintiffs have not advanced this theory on appeal, however, so we do not consider it.
. In addition to their claim under the Maine Unfair Trade Practices Act, the plaintiffs’ amended complaint also asserts a second count for unjust enrichment. Because neither side argues that the two claims require different preemption analyses, we do not separately discuss the unjust enrichment count.
. Most of these manufacturers belonged to the Tobacco Institute, an industry group that was disbanded in 1999 pursuant to the master settlement agreement between a number of states and cigarette companies. The testing has since continued at the Tobacco Industry Testing Laboratory, a similar facility.
. The FTC continued to collect the test results, at least through 2002, but has stopped reporting them, for reasons that are unclear from the record. The FTC has, however, made the results for the years 1999 through 2002 available in response to requests under the Freedom of Information Act, 5 U.S.C. § 552 (2007). Fed. Trade Comm’n, Cigarette Tar, Nicotine and Carbon Monoxide Yields Produced by Cigarette Manufacturers for the Years 1999-2002, available at http://www.ftc. gov/foia/frequentrequest.shtm.
. Each side also asked the district court to strike certain evidentiary materials or statements of fact submitted in connection with the motion for summary judgment. Some of these requests were denied and some were granted, but none of the district court’s rulings in this regard have been questioned on appeal.
. These labels are the now-familiar "Surgeon General’s Warning" statements, e.g., "Smoking Causes Lung Cancer, Heart Disease, Emphysema, and May Complicate Pregnancy.”
. From this point on, then, we will refer to the plurality opinion as simply "Cipollone," except when necessary to contrast the views of the dissenting opinion with those of the plurality.
. In doing so, the Court also overturned the ruling of the court of appeals that the FCLAA, which "revealed a congressional intent to exert exclusive federal control over every aspect of the relationship between cigarettes and health,” preempted all of the smoker's claims.
. Indeed, this was one of the primary points of disagreement between the
Cipollone
plurality and Justice Scalia, who argued in dissent that questions of FCLAA preemption "must focus not upon the ultimate source of the duty
(e.g.,
the common law) but upon its proximate application.”
. Indeed,
Reilly
notes that “Members of this Court have debated the precise meaning of 'based on smoking and health,’ " citing to the footnote in
Cipollone
— referenced here at note 11,
supra
— where the plurality rejects the views of the concurring and dissenting opinions on that point.
. Philip Morris relies on a recent decision of the California Supreme Court,
In re Tobacco Cases II,
. We note that these proceedings — which we henceforth refer to as “In re Tobacco Cases II" — are not the same as the In re Tobacco Cases II discussed in note 13, supra.
. Philip Morris questions the vitality of this holding in light of subsequent Supreme Court cases on the preemptive effect of other federal *41 statutory provisions. In Part II.B, infra, we consider, and reject, this argument.
. While the amended complaint includes allegations of fraudulent concealment, we read them to assert a basis for tolling the statute of limitations on the plaintiffs’ claims for relief, not a theory of recovery in their own right. Philip Morris does not argue that, to the extent § 1334(b) preempts fraudulent concealment claims, it also forecloses the use of that doctrine to toll the limitations period on a state-law claim that is otherwise not preempted, so we do not consider any such argument.
. While Justice Scalia agreed with the plurality’s conclusion that § 1334(b) preempts failure-to-warn claims unless they are based on a duty to make disclosures outside of ad
*43
vertising or promotion, he disagreed with the implication that the FCLAA's preemptive effect extends to state laws only insofar as they specify that warnings be provided through advertising or promotion.
. Furthermore, we reiterate our views that
Cipollone
does not differentiate between “express" and “implied" misrepresentations, and that such a dichotomy is impossible to square with its holding that fraudulent misrepresentation claims escape preemption because they "are predicated not on a duty ‘based on smoking and health,’ but rather on a more general duty — the duty not to deceive."
. In reaching the opposite conclusion,
Brown
adopted the reasoning of other courts, including the district court here, that fraud claims arising out of the statements "light” and "lower tar and nicotine” are preempted because the alleged " 'deception ... could easily be corrected by requiring an additional warning on the packages....' "
. In fact, Justice Scalia brought this very point to the plurality's attention, asserting that "it is not true that the States' laws governing fraud and misrepresentation impose identical legal standards."
. Philip Morris claims that these "arguments do not rely on the FCLAA” (emphasis added), but does not identify any other congressional action supporting them. Looking past this contradiction, we nonetheless consider whether the FCLAA can serve as a source of implied preemption. And insofar as Philip Morris's implied preemption theory relies on what it perceives as the FTC’s desire for uniform national standards of cigarette advertising, as we explain infra, we do not even think *48 that the FTC itself has enforced a uniform standard in this area.
. We nevertheless declined to forego implied preemption analysis altogether in reliance on
Cipollone,
because the state disclosure requirements had been challenged in part on the basis of amendments to the FCLAA which
Cipollone
had not considered.
. In support of this point, Philip Morris's brief relies heavily on the Eighth Circuit’s decision in
Watson v. Philip Morris Cos.,
. As the result of a subsequent cease-and-desist action against American, the company entered into another consent order with the FTC.
In re American Tobacco Co.,
. Similarly, when seeking relief on behalf of consumers for violation of a consent order, the FTC may proceed against the parties to the order only. 15 U.S.C. § 57b(a)(2).
.In the consent order resolving this charge, American agreed to refrain from representing, through certain comparisons of the tar ratings of any of its brands to those of other brands, “that consumers will get less tar by smoking ten packs of any cigarette rated as having 1 mg. of tar than by smoking a single pack of any other brand of cigarettes that is rated as having more than 10 mg. of tar.”
. In Part II.C, infra, we consider whether the FTC "permitted” the claims at issue so as to exempt them from the coverage of the Maine Unfair Trade Practices Act.
. Philip Morris intimates that the plaintiffs have waived any argument based on
Spriets-ma
because they did not rely on it below. Though the plaintiffs did not cite the case to the district court, they did argue that "no federal purpose or objective would be frustrated by a finding of liability against Defendants in this case.” In taking up this argument on appeal, then, we are free to consider
Sprietsma
— which, after all, is binding Supreme Court authority.
See, e.g., Air Line Pilots Ass’n, Int'l v. Guilford Transp. Indus., Inc.,
. Indeed, Philip Morris, while maintaining that "[t]he FTC has specifically permitted the use of descriptors ... that reflect the Cambridge Method's yield measurements," has nevertheless asked it to "adopt a rule expressly authorizing the industry to continue to use such descriptors” if accompanied by "disclaimers” about compensation and in accordance with "uniform” definitions of the terms to correspond to particular tar ratings. Petition for Rulemaking at 4, 34, In re Petition for Rulemaking Concerning Tar and Nicotine Testing and Disclosure (F.T.C. Sept. 18, 2002), available at http://www. ftc.gov/os/com-ments/philipmorrisconabisco/philipmorrispe-tition.pdf. The FTC has yet to rule on the petition.
. Philip Morris does not argue that the 1995 American Tobacco consent order relaxed the requirements of the 1971 order, so we do not separately discuss the 1995 order here.
. The court in
Price
read the 1971 consent order to authorize Philip Morris's use of the descriptors sans disclosures on the theory that the disclosure requirement “applies only when the manufacturer is making a direct comparison between its brand of cigarettes and a competing brand.”
