Circuit Judge.
Beer Nuts, Inc. (Beer Nuts) sued Clover Club Foods (Clover Club) alleging trademark infringement under 15 U.S.C. § 1114 (1976), unfair competition under 15 U.S.C. § 1125 (1976),
1
and a pendent claim of state law trademark infringement. These claims arose from Clover Club’s use of the words “Brew Nuts” with a picture of an overflowing stein on packages containing a sweetened, salted peanut product virtually identical to. a product sold by Beer Nuts. Clover Club counterclaimed, seeking a declaration that Beer Nuts’ registered trademark is void. After a bench trial, the district court denied relief to both parties and both parties have appealed. We reverse and remand for further proceedings.
*937 I.
TRADEMARK USE
The term “Beer Nuts” was registered as a trademark in 1955 and has become incontestable under section 1065. 2 Beer Nuts claims that its right to the exclusive use of its trademark has been infringed because Clover Club’s use of the term “Brew Nuts” together with an overflowing stein constitutes a trademark likely to cause confusion. The district court stated in its memorandum opinion, however, that “Clover Club’s use of the words ‘Brew Nuts’ is a description of its product rather than a trademark.” Rec., vol. I, at 51.
The defenses to the claimed infringement of an incontestable trademark are codified in section 1115
3
The “fair use” defense permits the use of a name or term,
other than as a trademark,
that is descriptive and is used fairly and in good faith only to describe the goods. § 1115(b)(4). This defense is not available if the alleged descriptive use is in fact a trademark use.
Soweco, Inc. v. Shell Oil Co.,
We do not believe the district court’s statement that “Brew Nuts” is used as a description rather than as a trademark was intended as a holding that Clover Club established a “fair use” defense under section 1115(b)(4). In the first place, Clover Club did not plead the “fair use” defense in its answer to the complaint, nor did it assert the defense as an issue in the pretrial order. Moreover, the district court made no findings that the descriptive use was accomplished “fairly and in good faith.”
See
§ 1115(b)(4);
cf. M.B.H. Enterprises v.
*938
WOKY, Inc.,
In any event, the record clearly establishes that Clover Club used the words “Brew Nuts” in conjunction with an overflowing stein as a trademark. A term or symbol is used as a trademark when the producer uses it to identify the source of his goods to the public and to distinguish those goods from others.
See M.B.H. Enterprises,
In this case, the words “Brew Nuts” are much larger than the other lettering on the package and in a different type style. The words are set off in a distinctive red-brown oval, outlined in dark brown and topped by a conspicuous white circle containing a picture of an overflowing beer stein. Below or above the oval, depending on the particular package, is the phrase actually used to describe the product: “sweetened salted peanuts.” Furthermore, the president of Clover Club, Robert Sanders, testified repeatedly that Clover Club uses secondary trademarks on some of its products in addition to the company name, and that “Brew Nuts” is such a trademark. 4
Based on our examination of the Clover Club package, the testimony of Mr. Sanders as to the trademark nature of the “Brew Nuts” logo, and the fact that Clover Club did not contend below that the “Brew Nuts” logo is not a trademark, we conclude as a matter of law that Clover Club has deliberately used “Brew Nuts” as a trademark.
II.
INFRINGEMENT
The district court held that the “Beer Nuts” trademark was not infringed. Based solely on a side-by-side comparison of the Beer Nuts and Brew Nuts packages, the court determined that “the product packaging and wording are sufficiently unique so as to preclude any likelihood of confusion as to the origin of the competing products.” Rec., vol. I, at 47 (emphasis in original). Beer Nuts argues that the trial court applied incorrect and incomplete legal standards in making this determination. A survey of the law applicable to the issue of infringement is necessary to provide a *939 framework for our disposition of this contention.
“A trademark is a distinctive mark, symbol, or emblem used by a producer or manufacturer to identify and distinguish his goods from those of others.”
Educational Development Corp. v. Economy Co.,
A generic mark has been described as referring to “ ‘a particular genus or class of which an individual article or service is but a member.’ ”
Soweco,
“A ‘descriptive’ term ‘identifies a characteristic or quality of an article or service,’ ... as, for example, its color, odor, function, dimensions, or ingredients.”
Soweco,
Infringement of a trademark occurs when the use of a similar mark is likely to cause confusion in the marketplace concerning the source of the different products.
Vitek Systems, Inc. v. Abbott Laboratories,
“(a) the degree of similarity between the designation and the trade-mark or trade name in
(i) appearance;
(ii) pronunciation of the words used;
(iii) verbal translation of the pictures or designs involved;
(iv) suggestion;
(b) the intent of the actor in adopting the designation;
(c) the relation in use and manner of marketing between the goods or services marketed by the actor and those marketed by the other;
(d) the degree of care likely to be exercised by purchasers.”
See Drexel Enterprises v. Richardson,
As set forth above, “[s]imilarity of the marks is tested on three levels: sight, sound, and meaning .... Each must be considered as [it] is encountered in the marketplace. Although similarity is measured by the marks as entities, similarities weigh more heavily than differences.”
AMF Inc.,
“It is not necessary for similarity to go only to the eye or the ear for there to be infringement. The use of a designation which causes confusion because it conveys the same idea, or stimulates the same mental reaction, or has the same meaning is enjoined on the same basis as where the similarity goes to the eye or the ear. Confusion of origin of goods may be caused alone by confusing similarity in the meaning of the designations em *941 ployed. The whole background of the case must be considered.”
Standard Oil Co.
v.
Standard Oil Co.,
In evaluating similarity, “[i]t is axiomatic in trademark law that ‘side-by-side’ comparison is not the test.”
Levi Strauss & Co. v. Blue Bell, Inc.,
“Intent on the part of the alleged infringer to pass off its goods as the product of another raises an inference of likelihood of confusion .... ”
Squirtco v. Seven-Up Co.,
Also relevant to likelihood of confusion are the means by which the products are marketed. “Converging marketing channels increase the likelihood of confusion.”
AMF Inc.,
Finally, the court must examine the degree of care with which the public will choose the products in the marketplace. “ ‘The general impression of the ordinary purchaser, buying under the normally prevalent conditions of the market and giving the attention such purchasers usually give in buying that class of goods, is the touchstone.’ ”
McGregor-Doniger,
In this case, the district court’s resolution of the infringement claim was improperly based solely on a side-by-side package comparison, although the parties presented evidence on other relevant factors, including Clover Club’s intent in adopting the trademark “Brew Nuts,” the manner in which Beer Nuts and Brew Nuts are marketed, and the degree of care purchasers exercise when buying the products.
*942
See Restatement of Torts,
§ 729(b), (c), (d). Moreover, the court erroneously equated likelihood of confusion with similarity.
See AMF Inc.,
III.
THE COUNTERCLAIM
In its counterclaim, Clover Club sought cancellation of the “Beer Nuts” trademark on two grounds: that the term “Beer Nuts” was generic and thus was not entitled to registration; and that the “Beer Nuts” registration was fraudulently obtained.
A trademark will be refused registration if it is “merely descriptive” of the goods of the applicant. § 1052(e). A “merely descriptive” term is a generic term. The courts have also equated a generic term with a “common descriptive name” as used in sections 1064(c) and 1065(4).
See Soweco,
Section 1064(c) also provides that an incontestable trademark may be cancelled if its registration was obtained fraudulently. A court should not lightly undertake cancellation on the basis of fraud,
Robert V. Vance & Associates, Inc. v. Baronet Corp.,
The district court denied Clover Club’s claim to strike the “Beer Nuts” registration on the basis of fraud. However, the court made no findings or conclusions on this issue to indicate the factual and legal bases for its decision. Fed.R.Civ.P. 52(a) provides that “the court shall find the facts specially and state separately its conclusions of law thereon.” In this case the court’s failure to comply with Rule 52(a) on
*943
the fraudulent registration issue renders meaningful appellate review impossible.
See Squirtco,
The case is reversed and remanded for reconsideration of the likelihood of confusion under the legal standards set forth in this opinion, and for findings of fact and conclusions of law on the question whether the “Beer Nuts” trademark was obtained fraudulently.

. Section 1065 provides in pertinent part:
“Except on a ground for which application to cancel may be filed at any time under subsections (c) and (e) of section 1064 of this title, .... the right of the registrant to use such registered mark in commerce for the goods or services on or in connection with which such registered mark has been in continuous use for five consecutive years subsequent to the date of such registration and is still in use in commerce, shall be incontestable .... ”
15 U.S.C. § 1065 (1976).
. Section 1115(b) provides:
“If the right to use the registered mark has become incontestable under section 1065 of this title, the registration shall be conclusive evidence of the registrant’s exclusive right to use the registered mark in commerce on or in connection with the goods or services specified in the affidavit filed under the provisions of said section 1065 subject to any conditions or limitations stated therein except when one of the following defenses or defects is established:
(1) That the registration or the incontestable right to use the mark was obtained fraudulently; or
(2) That the mark has been abandoned by the registrant; or
(3) That the registered mark is being used by or with the permission of the registrant or a person in privity with the registrant, so as to misrepresent the source of the goods or services in connection with which the mark is used; or
(4) That the use of the name, term, or device charged to be an infringement is a use, otherwise than as a trade or service 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 to users the goods or services of such party, or their geographic origin; or
(5) That the mark whose use by a party is charged as an infringement was adopted without knowledge of the registrant’s prior use and has been continuously used by such party or those in privity with him from a date prior to registration of the mark under this chapter or publication of the registered mark under subsection (c) of section 1062 of this title: Provided, however, That this defense or defect shall apply only for the area in which such continuous prior use is proved; or
(6) That the mark whose use is charged as an infringement was registered and used pri- or to the registration under this chapter or publication under subsection (c) of section 1062 of this title of the registered mark of the registrant, and not abandoned: Provided, however, That this defense or defect shall apply only for the area in which the mark was used prior to such registration or such publication of the registrant’s mark; or
(7) That the mark has been or is being used to violate the antitrust laws of the United States.”

. For example, Sanders testified:
“Q. (BY MR. JOHNSTON) This is the question [from Sanders’ deposition]: ....
You have told us that you selected the name Brew Nuts as a trademark for the sweet and salted peanuts. What names did you suggest for any of the other products?
Answer: The generic terms of the products.
Next question — ... So the sweetened salted one was the only one for which you felt the need of an additional trademark besides Clover Club?
You answered: Yes.
Do you recall being asked that question and giving that answer?
“A. Yes, I do.
“Q. And to what were you referring when you gave the answer?
“A. I was referring to the six or seven nut items that were then being sold under the Clover Club label.
“Q. And why did you say this was the only nut item that you decided to have carry a second trademark?
“A. I considered the other nut items really to be commodities and, therefore, I did not think there would be any value of putting a second mark on them.
“Q. And the product you sell in the Clover Club Brew Nuts package is not what you consider just a commodity?
“A. I consider it a specialty product.” Rec., vol. V, at 360-62.
“Q. Did your advertising agency ever suggest to you the use of the term Ah Nuts?
“A. Yes.
“Q. And why did you select Brew Nuts instead of Ah Nuts?
“A. I just felt that Ah Nuts was not a good second trademark.”
Id. at 389.
“Q. Mr. Sanders, I show you Plaintiff’s Exhibit 28-B. Brew Nuts is the dominant trademark on that package, isn’t it?
“A. I would say that the product itself is the dominant thing on the package, and that Brew Nuts is the dominant mark or fanciful term.”
Id. at 393.
. Suggestive trademarks “subtly connote something about the products.”
AMF Inc. v. Sleekcraft Boats,
Trademarks that are fanciful or arbitrary “bear no relationship to the product or service with which they are associated,”
Soweco, Inc. v. Shell Oil Co.,
These categories of trademarks are not relevant to the issues raised by the parties on appeal. Although Beer Nuts argued below that its trademark is suggestive, it does not urge this construction on appeal. See Reply Brief for Plaintiff-Appellant at 22 n. 7.
. The district court stated its concern that Beer Nuts was seeking to confirm a right to the exclusive use of “the entire pool of descriptive terms covering sweetened, salted peanuts suggested for consumption with beer or other ‘brew.’ ” Rec., vol. I, at 50. We agree with plaintiff that the lower court has misconceived the nature of the statutory protection afforded trademarks which Beer Nuts seeks to invoke. Beer Nuts cannot prevent Clover Club from using descriptive or generic words contained in *940 the “Beer Nuts” trademark to describe the Clover Club product fairly and in good faith. However, Beer Nuts alleges that Clover Club is using “Brew Nuts” as a trademark and that this use is likely to cause confusion in the marketplace over the source of the Clover Club product. This allegation states a claim for which the trademark laws provide a remedy. 15 U.S.C. § 1114 (1976).
. An “ ‘incontestable’ mark under section 1065 cannot be challenged as lacking secondary meaning; such marks are conclusively presumed to be nondescriptive or to have acquired secondary meaning.”
Soweco, Inc. v. Shell Oil Co.,
. Title 15 provides that a trademark can be cancelled:
“at any time if the registered mark becomes the common descriptive name of an article or substance, or has been abandoned, or its registration was obtained fraudulently or contrary to the provisions of section 1054 of this title or of subsections (a), (b), or (c) of section 1052 of this title for a registration hereunder, or contrary to similar prohibitory provisions of said prior Acts for a registration thereunder, or if the registered mark is being used by, or with the permission of, the registrant so as to misrepresent the source of the goods or services in connection with which the mark is used.”
15 U.S.C. § 1064(c) (1976).
