delivered the opinion of the Court. *
The question here is whether a party raising the statutory affirmative defense of fair use to a claim of trademark infringement, 15 U. S. C. § 1115(b)(4), has a burden to negate any likelihood that the practice complained of will confuse consumers about the origin of the goods or services affected. We hold it does not.

Each party to this case sells permanent makeup, a mixture оf pigment and liquid for injection under the skin to camouflage injuries and modify nature's dispensations, and each has used some version of the term “micro color” (as one word or two, singular or plural) in marketing and selling its product. Petitioner KP Permanent Make-Up, Inc., claims to have used the single-word version since 1990 or 1991 on advertising flyers and since 1991 on pigment bottles. Respondents Lasting Imprеssion I, Inc., and its licensee, MCN International, Inc. (Lasting, for simplicity), deny that KP began using the term that early, but we accept KP’s allegation as true for present purposes; the District and Appeals Courts took it to be so, and the disputed facts do not matter to our resolution of the issue.

In 1992, Lasting applied to the United States Patent and Trademark Office (PTO) under 15 U. S. C. § 1051 for registration of a trademark consisting of
It was also in 1999 that KP produced a 10-page advertising brochure using “microcolor” in a large, stylized typeface, provoking Lasting to demand that KP stop using the term. Instead, KP sued Lasting in the Central District of California, seeking, on more than one ground, a declaratory judgment that its language infringed no such exclusive right as Lasting claimed. 3 Lasting counterclaimed, alleging, among other things, that KP had infringed Lasting’s “Micro Colors” trademark.
KP sought summary judgment on the infringement counterclaim, based on the statutory affirmative defense of fair use, 15 U. S. C. § 1115(b)(4). After finding that Lasting had conceded that KP used the term only to describe its goods and not as a mark, the District Court held that KP was acting fairly and in good faith because undisputed facts showed that KP had employed the term “microcolor” continuously from a time before Lasting adopted the two-word, plural variant as a mark. Without enquiring whether the practice was likely to cause confusion, the court concluded that KP had made out its affirmativе defense under § 1115(b)(4) and
On appeal,
We granted KP’s petition for certiorari,

A
The Trademark Act of 1946, known for its principal proponent as the Lanham Act, 60 Stat. 427, as amended, 15 U. S. C. § 1051 et seq., provides the user of a trade or service mark with the opportunity to register it with the PTO, §§1051, 1053. If the registrant then satisfies further conditions including continuous use for five consecutive years, “the right... to use such registered mark in commerce” to designate the origin of the goods specified in the registration “shall be incontestable” outside certain listed exceptiоns. § 1065.
The holder of a registered mark (incontestable or not) has a civil action against anyone employing an imitation of it in commerce when “such use is likely to cause confusion, or to cause mistake, or to deceive.” § 1114(l)(a). Although an incontestable registration is “conclusive evidence ... of the registrant’s exclusive right to use the . . . mark in commerce,” § 1115(b), the plaintiff’s suсcess is still subject to “proof of infringement as defined in section 1114,”
ibid.
And that, as just noted, requires a showing that the defendant’s actual practice is likely to produce confusion in the minds of consumers about the origin of the goods or services in question. See
Two Pesos, Inc.
v.
Taco Cabana, Inc.,
“use of the name, term, or device charged to be an infringement is a use, otherwise than as a mark, ... of a term or device which is descriptive of and used fairly and in good faith only to describe the goods or services of such party, or their geographic origin . . . .” § 1115(b)(4).
Two points are evident. Section 1115(b) places a burden of proving likelihood of confusion (that is, infringement) on the party charging infringement even when relying on an incontestable registration. And Congress said nothing about likelihood of confusion in setting out the elements of the fair use defense in § 1115(b)(4).
Starting from these textual fixed points, it takes a long stretch to claim that a defense of fair use entails any burden to nеgate confusion. It is just not plausible that Congress would have used the descriptive phrase “likely to cause confusion, or to cause mistake, or to deceive” in §1114 to describe the requirement that a markholder show likelihood of consumer confusion, but would have relied on the phrase “used fairly” in § 1115(b)(4) in a fit of terse drafting meant to place a defendant under a burden to negate confusion. “ '[Wjhere Congress includes particular language in one section of a statute but omits it in another section of the same Act, it is generally presumed that Congress acts intentionally and purposely in the disparate inclusion or exclusion.’ ”
Russello
v.
United States,
Finally, a look at the typical course of litigation in an infringement action points up the incoherence of placing a burden to show nonconfusion on a defendant. If a plaintiff succeeds in making out a prima facie case of trademark infringement, including the element of likelihood of consumer confusion, the defendant may offer rebutting evidenсe to undercut the force of the plaintiff's evidence on this (or any) element, or raise an affirmative defense to bar relief even if the prima facie case is sound, or do both. But it would make no sense to give the defendant a defense of showing affirmatively that the plaintiff cannot succeed in proving some element (like confusion); all the defendant needs tо do is to leave the factfinder unpersuaded that the plaintiff has carried its own burden on that point. A defendant has no need of a court’s true belief when agnosticism will do. Put another way, it is only when a plaintiff has shown likely confusion by a preponderance of the evidence that a defendant could have any need of an affirmative defense, but under Lasting’s theory the dеfense would be foreclosed in such a case. “[I]t defies logic to argue that a defense may not be asserted in the only situation where it even becomes relevant.”

v.
Silstar Corp.,
Lаsting tries to extenuate the anomaly of this conception of the affirmative defense by arguing that the oddity reflects the “vestigial” character of the fair use defense as a historical matter. Tr. of Oral Arg. 39. Lasting argues that, because it was only in 1988 that Congress added the express provision that an incontestable markholder’s right to exclude is “subject to proof of infringement,” Trademark Law Revision Act of 1988, § 128(b)(1), 102 Stat. 3944, there was no
But the explanation does not work. It is not merely that it would be highly suspect in leaving the claimed element of § 1115(b)(4) redundant and pointless.

v.
Winn,
B
Since the burden of proving likelihood of confusion rests with the plaintiff, and the fair use defendant has no freestanding need to show confusion unlikely, it follоws (contrary to the Court of Appeals’s view) that some possibility of consumer confusion must be compatible with fair use, and so it
Since we do not rule оut the pertinence of the degree of consumer confusion under the fair use defense, we likewise do not pass upon the position of the United States, as ami-cus, that the “used fairly” requirement in § 1115(b)(4) demands only that the descriptive term describe the goods accurately. Tr. of Oral Arg. 17. Accuracy of course has to be a- consideration in assessing fair use, but the proceedings in this сase so far raise no occasion to evaluate some other concerns that courts might pick as relevant, quite apart from attention to confusion. The Restatement raises possibilities like commercial justification and the strength of the plaintiff’s mark. Restatement § 28. As to them, it is enough to say here that the door is not closed.
In sum, a plaintiff claiming infringement of аn incontestable, mark must show likelihood of consumer confusion as part of the prima facie case, 15 U. S. C. § 1115(b), while the defendant has no independent burden to negate the likelihood of any confusion in raising the affirmative defense that a term is used descriptively, not as a mark, fairly, and in good faith, § 1115(b)(4).
Because we read the Court of Appeals as requiring KP to shoulder a burden on the issue of confusion, we vacate the judgment and remand the case for further proceedings consistent with this opinion. 6
It is so ordered.
Notes
Justice Scalia joins all but footnotes 4 and 5 of this opinion. Justice Breyer joins all but footnote 6.
We note that in its brief to the Court of Appeals, Lasting appeal’s to have conceded KP’s use of “microcolor” in the early 1990’s. Appellants’ Opening Brief in No. 01-56055 (CA9), p. 8.
A trademark may be “any word, name, symbol, or device, or any combination thereof. . . used by a person ... to identify and distinguish his or her goods ... from those manufactured and sold by others and to indicate the source of the goods, even if that source is unknown.” 15 U. S. C. § 1127.
We summarize the proceedings in this litigation only as they are relevant to the question before us. The District Court’s findings as to the gеneric or descriptive nature of the term “micro color” and any secondary meaning that term has acquired by any of the parties, see Case No. SA CV 00-276-GLT (EEx) (CD Cal., May 16, 2001), pp. 3-5, 5-8, are not before us. Nor are the Court of Appeals’s holdings on these issues. See
Not only that, but the failure to say anything about a dеfendant’s burden on this point was almost certainly not an oversight, not after the House Subcommittee on Trademarks declined to forward a proposal to provide expressly as an element of the defense that a descriptive use be

The record indicates that on remand the courts should direct thеir attention in particular to certain factual issues bearing on the fair use defense, properly applied. The District Court said that Lasting’s motion for summary adjudication conceded that KP used “microcolor” descriptively and not as a mark. Case No. SA CV 00-276-GLT (EEx), at 8, App. to Pet. for Cert. 29a. We think it is arguable that Lasting made those concessions only as to KP’s use of “microcolor” on bottles and flyers in the early 1990’s, not as to the stylized version of “microcolor” that appeared in KP’s 1999 brochure. See Opposition to Motion for Summary Judgment/ Adjudication in Case No. SA CV 00-276-GLT (EEx) (CD Cal.), pp. 18-19; Appellants’ Opening Brief in No. 01-56055 (CA9), pp. 31-32. We also note that the fair use analysis' of KP’s employment of the stylized version of “microcolor” on its brochure may differ from that of its use of the term on the bottles and flyers.
