Plaintiff-appellant International Information Systems Security Certification Consortium, Inc. (“ISC2”) filed suit against defendants-appellees Security University (“SU”) and Sondra Schneider, alleging that SU’s use of ISC 2’s certification mark violated the Lanham Act, 15 U.S.C. § 1051 et seq., and constituted infringement under 15 U.S.C. § 1114, false designation of origin and false advertising under 15 U.S.C. § 1125(a), and trademark dilution under 15 U.S.C. § 1125(c), and that SU’s use of the mark constituted unfair competition under the Connecticut Unfair Trade Practices Act, Conn. GemStat. § 42-110a et seq. (“CUTPA”). Following cross-motions for summary judgment, the district court granted summary judgment to defendants on all grounds, holding that defendants’ use of the certification mark constituted nominative fair use under the Ninth Circuit’s test, which our Court has not, to this point, adopted. Critical to its determination that defendants’ use of the mark constituted nominative fair use under the Ninth Circuit’s test were the dis
Having considered other circuits’ nominative fair use tests as well as our own prior treatment of claims involving nominative use, we hold that nominative fair use is not an affirmative defense to a claim of infringement under the Lanham Act. We further hold that in cases involving nominative use, in addition to considering the Polaroid factors, courts are to consider (1) whether the use of the plaintiffs mark is necessary to describe both the plaintiffs product or service and the defendant’s product or service, that is, whether the product or service is not readily identifiable without use of the mark; (2) whether the defendant uses only so much of the plaintiffs mark as is necessary to identify the product or service; and (3) whether the defendant did anything that would, in conjunction with the mark, suggest sponsorship or endorsement by the plaintiff holder, that is, whether the defendant’s conduct or language reflects the true or accurate relationship between plaintiffs and defendant’s products or services. When considering these factors, courts must be mindful of the different types of confusion relevant to infringement claims, including confusion as to sponsorship, affiliation, or connection, as well as, when considering a certification mark, the various ways such a mark can be infringed.
Because the district court failed to consider the Polaroid factors and because its consideration of the relevant nominative fair use factors was based on incorrect assumptions, we vacate the district court’s grant of summary judgment on the infringement claims. Accordingly, we also vacate the grant of summary judgement on the false designation of origin and false advertising claims, which the court decided on the same grounds as the infringement claims, and the CUTPA claims, which were dismissed because they were derivative of the Lanham Act claims. We affirm the grant of summary judgment on the dilution claims, which ruling was not challenged on appeal. We remand for further proceedings consistent with this opinion.
BACKGROUND
I. The CISSP® Mark
A. ISC 2,s Mark
ISC2 is a non-profit organization that was formed in 1989 to develop standards for the information security industry. In March 1990, ISC2 developed a certification program and began using the certification mark “CISSP®” to denote a “Certified Information Systems Security Professional” who has met certain requirements and standards of competency in the information security field, including passing the CISSP® certification examination that ISC2 administers.
On March 18, 1997, the United States Patent and Trademark Office registered ISC2’s CISSP® certification mark. The registration stated: “The [CISSP®] certification mark is used by persons authorized by the certifier [ISC2] to certify completion of appropriate work experience and/or successfully passing examinations as established by the certifier in the field of security of information systems.” App’x at 30.
B. SU’s Alleged Infringement
SU is a for-profit company that was formed in 1999 by defendant-appellee Sondra Schneider, a CISSP®-certified individual, to provide information security training. SU offers various classes, including a class to prepare individuals for ISC2’s CISSP® certification examination. SU has used the CISSP® mark in connection
However, ISC2 objects to some of SU’s advertisements, run between 2010 and 2012, which, ISC2 argues, misleadingly suggested that SU’s instructor, Clement Dupuis, had attained some higher level of certification as a “Master CISSP” or “CISSP Master.” These advertisements include the following statements:
• “MASTER THE 10 CISSP DOMAINS with the Master CISSP® Clement Dupuis.” App’x at 71.
• “REGISTER NOW to Master the CISSP® Certification with Master CISSP® Instructor Clement Dupuis of www.ccure.org!” App’x at 71.
• “Register for CISSP® Prep class with Master CISSP Clement Dupuis today!” App’x at 76.
• “You are taught by CISSP Master Clement Dupuis, the father of www. ccure.org website.” App’x at 76, 83.
• “Security University’s CISSP® Prep Class[.] Register for CISSP® Prep ' class with Master CISSP Clement Du-puis today!” App’x at 78, 83.
• “Attend the BEST CISSP® Prep Class in Europe[.] Master CISSP June 27-30 AMERSTERDAM with MASTER CISSP® Instructor Clement Dupuis[.]” App’x at 88-89.
SU began using the term “Master” in May 2010. On June 9, 2010, ISC 2’s counsel wrote to Schneider asking that she cease using the phrase “Master CISSP” in SU’s advertisements. On June 13, 2010, Schneider emailed Marc Thompson, an employee of a third party entity that oversees ' seminars on ISC 2’s behalf, stating that “SU will continue to use the word Master. Master Clement Dupuis is a Male Teacher [and] thus he is a Master according to the dictionary.” Int’l Info. Sys. Sec. Certification Consortium, Inc. v. Sec. Univ., LLC [hereinafter IISSCC ], No. 3:10-CV-01238 (MPS),

B. Summary Judgment Motions
In December 2013, the parties cross-moved for summary judgment. On August 7, 2014, the district court granted summary judgment to SU on all counts. In sum, the district court found that ISC
Central to the district court’s analysis was its conclusion that “Defendants’ addition of the word ‘Master’ before or after ‘CISSP®’.... does not implicate the protection afforded by trademark infringement laws, which are concerned with ‘whether there exists a likelihood that an appreciable number of ordinarily prudent purchasers will be misled, or indeed simply confused, as to the source of the goods in question.’ ” Id. at *5-6 (quoting Thompson Med. Co. v. Pfizer Inc.,
Although not necessary to its conclusion, the district court reasoned that the disclaimers SU placed at the bottom of some of its advertisements further served to reduce any suggestion that their classes were sponsored or endorsed by ISC2. Several, but not all of SU’s advertisements, included one or more of the following disclaimers:
• SU CISSP® Prep classes are not endorsed, sponsored or delivered by (ISC)2®.
• CISSP® is a registered trademark of (ISC)2®.
• CISSP® is a registered trademark of (ISC)2® (International Information Systems Security Certification Consortium) Inc.
• CISSP® is a registered trademark of (ISC)2® Inc. (International Information Systems Security Certification Consortium) Inc. The materials for the Security University classes have been developed specifically for SU and are not endorsed, sponsored or delivered by (ISC)2®. The goal of the course is to prepare security professionals for the CISSP® exam by covering the ten domains defined by (ISC)2®.

Without further analysis, the district court concluded that ISC
DISCUSSION
I. Certiñeation Marks
A “certification mark,” such as CISSP®, is a special sub-category of marks which, unlike other trademarks, is intended to be used by those other than its owner, to indicate the quality, accuracy, or other characteristics of the goods or services. See 15 U.S.C. § 1127 (defining “certification mark” as “any word, name, symbol, or device, or any combination thereof — (1) used by a person other than its owner, or (2) which its owner has a bona fide intention to permit a person other than the owner to use in commerce and files an application to register on the principal register established by this chapter, to certify regional or other origin, material, mode of manufacture, quality, accuracy, or other characteristics of such person’s goods or services or that the work or labor on the goods or services was performed by members of a union or other organization”). The CISSP® mark is meant to certify quality and characteristics, that is, that the security information professional bearing the CISSP® mark meets ISC 2’s standards and has passed its competency test.
In spite of the differences between certification marks and other types of marks, the Lanham Act provides that certification
[S]o far as they are applicable, ... certification marks, ... shall be registrable under this chapter, in the same manner and with the same effect as are trademarks, by persons ... exercising legitimate control over the use of the marks sought to be registered, even though not possessing an industrial or commercial establishment, and when registered they shall be entitled to the protection provided in this chapter in the case of trademarks, except in the case of certification marks when used so as to represent falsely that the owner or a user thereof makes or sells the goods or performs the services on or in connection with which such mark is used.
15 U.S.C. § 1054 (emphases added); see also Am. Bd. of Psychiatry and Neurology, Inc. v. Johnson-Powell,
II. Infringement Claims
To prevail on a claim of certification mark infringement, “a plaintiff must show, first, that its mark merits protection, and, second, that the defendant’s use of a similar mark is likely to cause consumer confusion.” Brennan’s, Inc. v. Brennan’s Rest., L.L.C.,
“A plaintiffs trademark is protected by federal law against infringement by use of colorable imitations of the mark which are ‘likely to cause confusion, or to cause mistake, or to deceive.’ ” Hormel Foods Corp. v. Jim Henson Prods., Inc.,
The eight factors are: (1) strength of the trademark; (2) similarity of the marks; (3) proximity of the products and their competitiveness with one another; (4) evidence that the senior user may “bridge the gap” by developing a product for sale in the market of the alleged infringer’s product; (5) evidence of actual consumer confusion; (6) evidence that the imitative mark was adopted in bad faith; (7) respective quality of the products; and (8) sophistication of consumers in the relevant market.
Starbucks Corp. v. Wolfe’s Borough Coffee, Inc.,
the Polaroid factors are not, of course, “exclusive” and should not be applied “mechanically.” No single factor is dis-positive, and cases may certainly arise where a factor is irrelevant to the facts at hand. But it is incumbent upon the district judge to engage in a deliberate review of each factor, and, if a factor is inapplicable to a case, to explain why.
A. Types of Confusion Relevant to Infringement Claims
The district court held that the only type of confusion relevant in determining infringement is confusion as to source. This is incorrect; protection is not exclusively limited for any type of mark to cases in which there may be confusion as to source.
use[s] in commerce any reproduction, counterfeit, copy, or colorable imitation of a registered mark in connection with the sale, offering for sale, distribution, or advertising of any goods or services on or in connection with which such use is likely to cause confusion, or to cause mistake, or to deceive ....
15 U.S.C. § 1114(l)(a) (emphasis added). As is plain from this statutory text, the Act’s protection against infringement is not limited to any particular type of consumer confusion, much less exclusively to confusion as to source. Rather, the Lanham Act protects against numerous types of confusion, including confusion regarding affiliation or sponsorship. See Rescuecom Corp.,
This broader prohibition on consumer confusion as to sponsorship or approval is also made explicit in Section 43 of the Lanham Act, which prohibits false advertising and false designation of origin by providing for civil penalties to a person injured by:
Any person who, on or in connection with any goods or services, ... uses in commerce any word, term, name, symbol, or device, or any combination thereof, or any false designation of origin, false or misleading description of fact, or false or misleading representation of fact, which—
(A) is likely to cause confusion, or to cause mistake, or to deceive as to the affiliation, connection, or association of such person with another person, or as to the origin, sponsorship, or approval of his or her goods, services, or commercial activities by another person, or
(B) in commercial advertising or promotion, misrepresents the nature, characteristics, qualities, or geographic origin of his or her or another person’s goods, services, or commercial activities....
15 U.S.C. § 1125(a)(1) (emphases added).
Indeed, our case law demonstrates that consumer confusion is plainly not limited to source confusion. For example, in Weight Watchers International, Inc. v. Luigino’s, Inc.,
B. Infringement of Certification Marks
In addition to erroneously treating source confusion as the only relevant type of confusion, the district court also took an erroneously narrow view of how certification marks can be infringed. There are numerous ways in which a certification mark can be infringed. Two of the most well-established “[e]xamples of infringement of a certification mark are: the use of the mark in a resume of a professional who is in fact not certified by the organization that is the owner of the mark; and the use of the mark on goods that have not in fact been certified.” McCarthy § 19:92.50 (footnotes omitted); see, e.g., Am. Bd. of Psychiatry and Neurology, Inc.,
But these are not the exclusive means of infringing on a certification mark. Although the district court expressed skepticism that “it is possible for the CISSP® certification mark to be infringed by a party who has met all the requirements for certification,” see IISSCC,
The Trademark Board has determined that the junior user’s certification status is irrelevant to whether it causes a likelihood of confusion with a senior certification mark. The Trademark Board “has indicated that even where a defendant’s product contains ingredients which have been certified by the owner of a certification mark, the defendant’s incorporation of that certification mark into its own composite trademark might be likely to cause confusion as to sponsorship, affiliation or connection.” McCarthy § 19:92.50 (citing Institut Nat’l Des Appellations d’Origine v. Brown-Forman Corp.,
Accordingly, although a person who is not certified can infringe a certification mark by engaging in unlicensed use of the mark, this is not the only manner of misusing a certification mark that is cognizable in an infringement suit. Just as it would infringe the “Darjeeling” certification mark for a competitor to identify genuine, certified Darjeeling tea with its own composite mark “Darjeeling Nouveau,” id., the district court erred in failing to consider that SU may have infringed on ISC2’s certification mark by identifying its certified instructor as “Master CISSP” and “CISSP Master.”
Importantly, it is not a prerequisite to ISC 2’s claim of infringement “that the defendant was using the allegedly infringing content ‘as a [certification] mark.’ ” Kelly-Brown,
C. Likelihood of Confusion in Nominative Use Cases
Having determined that the district court erred in considering only source confusion and erroneously limiting the ways in which certification marks can be infringed, we turn to the question of how the district court should assess likelihood of confusion on remand.
As discussed above, our Court’s test for assessing likelihood of confusion is the Polaroid test. As noted, courts are to consider the following eight non-exclusive factors:
(1) strength of the trademark; (2) similarity of the marks; (3) proximity of the products and their competitiveness with one another; (4) evidence that the senior user may “bridge the gap” by developing a product for sale in the market of the alleged infringer’s product; (5) evidence of actual consumer confusion; (6) evidence that the imitative mark was adopted in bad faith; (7) respective quality of the products; and (8) sophistication of consumers in the relevant market.
Starbucks Corp.,
The district court, rather than applying the Polaroid factors, applied the Ninth Circuit’s test which applies in cases of nominative use of marks. Nominative use is a “use of another’s trademark to identify, not the defendant’s goods or services, but the plaintiffs goods or services.” McCarthy § 23:11. It is called “nominative” use “because it ‘names’ the real owner of the mark.” Id. “The doctrine of nominative fair use allows a defendant to use a plaintiffs trademark to identify the plaintiffs goods so long as there is no likelihood of confusion about the source of the defendant’s product or the mark-holder’s sponsorship or affiliation.” Tiffany (NJ) Inc. v. eBay Inc.,
First, the product or service in question must be one not readily identifiable without use of the trademark; second, only so much of the mark or marks may be used as is reasonably necessary to identify the product or service; and third, the user must do nothing that would, in conjunction with the mark, suggest sponsorship or endorsement by the trademark holder.
Id. at 308 (footnote omitted). Other circuits have adopted variations of this test. See, e.g., Universal Commc’n Sys., Inc. v. Lycos, Inc.,
In the Ninth Circuit, nominative fair use is not an affirmative defense because it does not protect a defendant from liability if there is, in fact, a likelihood of consumer confusion. Rather, the nominative fair use test replaces the multi-factor test that the Ninth Circuit typically employs to determine consumer confusion, i.e., it replaces the Ninth Circuit’s analogue to the Polaroid test. See Cairns v. Franklin Mint Co.,
By contrast, the Third Circuit, another court to have developed a nominative fair use doctrine, affords defendants broader protection. The Third Circuit treats nominative fair use as an affirmative defense that may be asserted by the defendant despite a likelihood of consumer confusion. To be entitled to protection based on the affirmative defense, a defendant must show
(1) that the use of plaintiffs mark is necessary to describe both the plaintiffs product or service and the defendant’s product or service; (2) that the defendant uses only so much of the plaintiffs mark as is necessary to describe plaintiffs product; and (3) that the defendant’s conduct or language reflect the true and accurate relationship between plaintiff and defendant’s products or services.
Century 21 Real Estate Corp.,
To this point, this Court has not adopted either the Ninth Circuit or the Third Circuit’s rule on nominative fair use. See Tiffany (NJ) Inc.,
Having considered the case law, as well as the positions of the United States Patent and Trademark Office,
That the use of the name, term, or device charged to be an infringement is a use, otherwise than as a mark, of the party’s individual name in his own business, or of the individual name of anyone in privity with such party, or 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....
15 U.S.C. § 1115(b)(4); see KP Permanent Make-Up, Inc.,
We turn next to the question of whether we should adopt a nominative fair use test, either to supplant or to replace the Polaroid test. Although we see no reason to replace the Polaroid test in this context, we also recognize that many of the Polaroid factors are a bad fit here and that we have repeatedly emphasized that the Polaroid factors are non-exclusive. And although we have not expressly rejected or accepted other circuits’ nominative fair use tests, we “have recognized that a defendant may lawfully use a plaintiffs trademark where doing so is necessary to describe the plaintiffs product and does not imply a false affiliation or endorsement by the plaintiff of the defendant.” Tiffany (NJ) Inc.,
Because we believe that the nominative fair use factors will be helpful to a district court’s analysis, we hold that, in-nominative use cases, district courts are to consider the Ninth Circuit and Third Circuit’s nominative fair use factors, in addition to the Polaroid factors.
When assessing the second nominative fair use factor, courts are to consider whether the alleged infringer “step[ped] over the line into a likelihood of confusion by using the senior user’s mark too prominently or too often, in terms of size, emphasis, or repetition.” McCarthy § 23:11; see, e.g., PACCAR Inc. v. TeleScan Technologies, L.L.C.,
Additionally, when considering the third nominative fair use factor, courts must not, as the district court did here, consider only source confusion, but rather must consider confusion regarding affiliation, sponsorship, or endorsement by the mark holder. See Courtenay Commc’ns Corp. v. Hall,
We therefore remand for reconsideration of the Polaroid factors in addition to the nominative fair use factors, keeping in mind the numerous types of confusion that are relevant to an infringement analysis other than mere source confusion and the numerous ways in which a certification mark may be infringed.
III. Remaining Claims
We now turn to ISC 2’s remaining claims. First, we affirm the district court’s ruling on ISC2’s trademark dilution claims, which was not challenged on appeal. ISC2 argues that the district court’s rulings on the other claims — the false designation of origin and the CUTPA claims — should be vacated for the same reasons as the court’s ruling on the infringement claims. We agree. The district court decided the false designation of origin claims in the same erroneous manner in which it decided the infringement claims, and its ruling must therefore be vacated. Finally, the district court held that the CUTPA claims were derivative of the Lanham Act claims and, because the Lanham Act claims failed, so did the CUT-PA claims. Because we reinstate the Lan-ham Act infringement and false designation of origin claims, we also vacate the district court’s summary judgment ruling on the CUTPA claims.
CONCLUSION
For the foregoing reasons, we VACATE the district court’s grant of summary judgment on ISC 2’s infringement, false designation of origin, and CUTPA claims, and REMAND for further proceedings consistent with this opinion. We AFFIRM the district court’s grant of summary judgment on ISC 2’s trademark dilution claims.
Notes
. Upon meeting ISC2’s certification standards, ISC 2 licenses an individual to use the CISSP® mark in accordance with the "(ISC)2 ® Regulations Governing Use of Certification/Collective Marks.” The Regulations provide that, in using the mark, certified individuals "may not combine the Logo with any other object, including, but not limited to, other logos, icons, words, graphics, photos, [or] slogans ... (i.e., Mixing another Logo with the CISSP[®] Logo to create a variation.)” Int’l Info. Sys. Sec. Certification Consortium, Inc. v. Sec. Univ., LLC, No. 3:10-CV-01238 (MPS),
. Our analysis is not changed by the district court’s passing note that “attaching the word ‘Master’ to 'CISSP®' does not 'suggest sponsorship or endorsement ’ by (ISC)2.” IISSCC,
. Indeed, considering only source confusion would make little sense in the context of certification marks, as certification marks are generally not used to designate source at all.
. On the other hand, these facts might be taken into account in assessing such Polaroid factors as "proximity of the products and competitiveness with one another” and the possibility that the “senior user may 'bridge the gap' by developing a product for sale in the market of the alleged infringer’s product.” Starbucks Corp.,
. We invited the United States Patent and Trademark Office to submit a letter brief regarding several issues to be decided in this appeal. It did so on August 14, 2015 and August 31, 2015, through submissions signed by the United States Patent and Trademark Office and the Department of Justice. "We consider the views expressed therein for persuasive value.” Serricchio v. Wachovia Sec., LLC,
. As we have emphasized with reference to the Polaroid factors, this combination of factors is not exclusive, and other factors may be considered where relevant.
