    OPINION
    NIEMEYER, Circuit Judge:
    Shakespeare Company, the owner of a registered trademark for
    fishing rods that have a "whitish translucent" tip and a contrasting
    opaque shaft, brought this trademark infringement action against Sil-
    star Corporation of America, Inc. which also manufactures a clear-
    tipped fishing rod. Because of the functional or descriptive aspects of
    Shakespeare's mark, the district court initially ordered the Commis-
    sioner of the Patent and Trademark Office to cancel its registration.
    See Shakespeare Co. v. Silstar Corp. of America, Inc. (Shakespeare
    I), 
    802 F. Supp. 1386
     (D.S.C. 1992). On appeal, however, we held
    that because Shakespeare's trademark had become incontestable
    under 
    15 U.S.C. § 1065
    , it could not be canceled. We remanded the
    case for resolution of the remaining infringement issues. See
    Shakespeare Co. v. Silstar Corp. of America, Inc. (Shakespeare II),
    
    9 F.3d 1091
     (4th Cir. 1993). On remand, the district court found,
    among other things, that "Silstar's use of the clear tip on its fishing
    rods will [not] create a likelihood of confusion" and that, in any event,
    Silstar had "established its fair-use defense." Shakespeare Co. v. Sil-
    star Corp. of America, Inc. (Shakespeare III ), 
    906 F. Supp. 997
    , 1001
    (D.S.C. 1995). We now affirm.
    I
    In the 1940s, fishing rods were manufactured from either hollow
    or solid fiberglass. Hollow fiberglass rods were lighter and less
    expensive than solid ones, but they were also more inclined to break,
    particularly at the tip. While solid rods were stronger, they were also
    heavier and more expensive than the hollow ones.
    2
    Shakespeare, which has been one of the leading manufacturers of
    fishing rods, developed a process that combined the benefits of each
    type of rod by joining a hollow fiberglass base to a solid fiberglass
    tip. With developments in graphite in the mid 1970s, Shakespeare
    added a graphite core to the base of the rod, making it even stronger.
    The tip remained solid fiberglass, which is both strong and flexible.
    Shakespeare patented its invention and for years was the only manu-
    facturer of fishing rods with a hollow graphite base and a solid fiber-
    glass tip.
    Because graphite is naturally charcoal gray and fiberglass is natu-
    rally clear or "whitish translucent," Shakespeare's rods had a distinc-
    tive appearance when compared to those of its competitors. While
    Shakespeare was at first troubled by the aesthetically unappealing
    two-toned rod, with increased consumer acceptance Shakespeare
    sought to capitalize on its appearance, deliberately marketing it in its
    natural two-toned appearance so that consumers could recognize the
    graphite base and solid fiberglass tip. Shakespeare denominated the
    rod the "Ugly Stik" and applied to the Patent and Trademark Office
    to register both the "Ugly Stik" mark and the two-toned appearance
    of the rod. The Patent and Trademark Office issued both trademarks.
    The mark covering the appearance of the rod claims exclusive right
    to market a fishing rod,
    in which the tipped portion of the shaft between the tip and
    the second line guide elements consist of whitish translucent
    material in contrast to the opaque remainder of the shaft.
    United States Trademark 
    Registration No. 1,261,786
     (registered on
    the Principal Register). In 1989, this trademark became incontestable
    under 
    15 U.S.C. § 1065
    .
    Silstar Corporation of America, Inc., a competing manufacturer
    who desired for quality purposes to market a fishing rod with a graph-
    ite base and fiberglass tip, began manufacturing such a rod through
    a process different from that used by Shakespeare. Because Silstar
    wanted to communicate to consumers the rod's graphite and fiber-
    glass properties, Silstar left these materials with their natural color.
    The base and tip of its rods consequently appeared like Shake-
    speare's. Silstar called its rod the "Power Tip Crystal" rod. When Sil-
    3
    star introduced this rod in 1990, it knew that Shakespeare had a
    trademark for a rod with a "whitish translucent" tip and contrasting
    opaque base.
    In response to Silstar's introduction of the Power Tip Crystal rod,
    Shakespeare filed this trademark infringement action. In defense, Sil-
    star contended that Shakespeare could not claim a mark in the func-
    tional or descriptive design of the rod, arguing that even though
    Shakespeare's mark had become incontestable, it should be canceled
    by the court under 
    15 U.S.C. § 1119
    . The case was tried to the district
    court without a jury, and after making findings of fact, the district
    court agreed with Silstar that Shakespeare's mark should be canceled.
    See Shakespeare I, 
    802 F. Supp. at 1399
    . The court found that Shake-
    speare's mark was nothing more than the natural appearance of the
    functional features of graphite fishing rods with solid fiberglass tips
    and therefore concluded that Shakespeare's mark was not subject to
    registration. See 
    id. at 1398-99
    . The court ordered the Commissioner
    of the Patent and Trademark Office to cancel Shakespeare's mark
    from the register. See 
    id. at 1399
    .
    On appeal we reversed, holding that the Lanham Act did not autho-
    rize courts to cancel trademark registrations because of their function-
    ality once they had become incontestable under 
    15 U.S.C. § 1065
    . We
    summarized:
    [W]e hold that the district court erred in canceling, pursuant
    to 
    15 U.S.C. § 1119
    , the trademark held by Shakespeare on
    the grounds that it is functional, because that is not an autho-
    rized ground for cancellation under 
    15 U.S.C. § 1064
    . Since
    no other ground enumerated under § 1064 was alleged by
    Silstar, the mark is valid as a matter of law. We therefore
    reverse the district court and remand the case for further
    consideration of Shakespeare's statutory and common law
    infringement and unfair competition claims. We further
    instruct the district court that any inquiry into an alleged
    "fair use" of the clear tip must be accompanied by an analy-
    sis of the likelihood of confusion among consumers that
    may be created by Silstar's use of the clear tip.
    Shakespeare II, 
    9 F.3d at 1099
    .
    4
    On remand, the district court addressed the remaining infringement
    issues and held that Shakespeare had failed to establish a likelihood
    of confusion from Silstar's clear-tipped rods and, alternatively, that
    Silstar had established its fair-use defense. See Shakespeare III, 906
    F. Supp. at 1001. The court also concluded that Silstar had failed to
    establish its unclean hands defense and its counterclaims. See id.
    In assessing the likelihood of confusion from Silstar's fishing rods,
    the district court noted that Shakespeare was not entitled to a pre-
    sumption of a likelihood of confusion based on Silstar's copying of
    Shakespeare's Ugly Stik rod. It concluded that because Silstar had
    merely sought "to reproduce and utilize a functional attribute, which
    is unquestionably a legitimate activity," Id. at 1010, the presumption
    of a likelihood of confusion was not created because such a presump-
    tion arises only from an "`intent to exploit the good will created by
    an already registered mark.'" Id. (quoting AMP, Inc. v. Foy, 
    540 F.2d 1181
    , 1186 (4th Cir. 1976)). In finding no exploitative intent, the
    court reiterated several of its factual findings: that Silstar used the
    clear tip to demonstrate its rods' quality, not as indicating origin; that
    whatever attention was drawn to the clear tip served only to inform
    buyers of the rods' components; that Silstar's descriptive use of the
    clear tip was the most effective means of marketing its rods in the
    descriptive sense; and, that there was no alternative as effective for
    demonstrating to consumers the rods' components since a clear tip
    and opaque gray shaft are the natural colors resulting from the manu-
    facturing process. See 
    id.
    In support of its factual finding that Silstar's Power Tip Crystal rod
    was not likely to be confused with Shakespeare's Ugly Stik rod, the
    court found that, other than color similarities of the materials them-
    selves, Silstar's rod differed significantly in overall appearance from
    the Shakespeare rod and that Silstar had taken specific measures to
    distinguish its rod. See id. at 1011. The court noted that although both
    companies used the same marketing facilities, the rods were usually
    displayed in a way that allowed consumers readily to see the manu-
    facturer's names, and that consumers usually inspected rods thor-
    oughly before purchasing them. See id. The court acknowledged that
    the similar advertising channels and relative strength of Shakespeare's
    mark somewhat favored finding a likelihood of confusion. See id. at
    1012-13. But, the court noted, Shakespeare's mark was not particu-
    5
    larly strong; rather it was descriptive with some secondary meaning
    on which Shakespeare's marketing had not put much emphasis. See
    id. at 1013. At bottom, the court concluded that while the number of
    factors which favored Shakespeare was greater than the number
    which favored Silstar, the weight of the factors favoring Silstar was
    significantly greater than the weight of those favoring Shakespeare.
    See id. at 1014. The district court thus found as a matter of fact that
    Shakespeare had failed to establish a likelihood of confusion, an
    essential element of its infringement claim. See id.
    In finding alternatively that Silstar had established a fair-use
    defense, the district court concluded that the fair-use defense may be
    available even where a likelihood of confusion has been established,
    and that "`the strength of the plaintiff's mark and the extent of likely
    or actual confusion are important factors in determining whether a use
    is fair.'" Id. at 1015 (quoting Restatement (Third) of Unfair
    Competition, § 28 cmt. b (1995)). The court reiterated that it did not
    find Shakespeare's mark to be particularly strong, but that even if it
    were strong, its strength did not "outweigh Silstar's right to use the
    clear tip, . . . a functional attribute of these types of rods . . . as a
    descriptive device." Id. The court noted that Silstar acted in good faith
    in using the functional characteristics of the clear tip and in not seek-
    ing to use it as an identification of source. See id. at 1016. In reaching
    that conclusion, the court considered that the functionality and
    descriptiveness of Shakespeare's mark were relevant factors. See id.
    This appeal followed.
    II
    Shakespeare first argues that as a matter of law, our earlier decision
    in Shakespeare II foreclosed any district court ruling based on the
    functional and descriptive aspects of its trademark because we held
    that a mark cannot be canceled on the ground that it is functional after
    it has become incontestable. Because the district court considered the
    functional and descriptive aspects of Shakespeare's trademark in
    determining that Silstar's actions were in good faith and constituted
    fair use, the district court's findings must, Shakespeare contends, be
    reversed. This argument raises a legal question which we review de
    novo.
    6
    In Shakespeare II, we held that the district court erred in canceling
    Shakespeare's trademark pursuant to 
    15 U.S.C. § 1119
     on the grounds
    that it was functional. We concluded that 15 U.S.C.§ 1064 does not
    include functionality as a ground for cancellation. See Shakespeare II,
    
    9 F.3d at 1097
    . In reaching our conclusion, however, we considered
    functionality only as it might be a ground for canceling incontestable
    marks, observing that "since no other ground enumerated under
    § 1064 was alleged by Silstar, the mark is valid as a matter of law."
    Id. at 1099. Having disposed of that one issue, we remanded the case
    to the district court for consideration of the other issues in Shake-
    speare's infringement claim. See id. Under our holding, therefore, the
    district court could not on remand cancel Shakespeare's registration
    or find it otherwise invalid because of functionality. But in delimiting
    the court's power under 
    15 U.S.C. § 1119
     and saying that the mark
    was valid as a matter of law, we did not hold that Shakespeare had
    proved the other elements of its trademark infringement case. Nor did
    we say that functionality or descriptiveness were irrelevant to other
    issues before the district court on remand. Accordingly, to the extent
    that either functionality or descriptiveness is relevant in considering
    either Shakespeare's prima facie case for infringement or Silstar's
    fair-use defense, the district court did not err.*
    On remand, the district court considered the functionality and
    descriptiveness of Shakespeare's mark in determining (1) whether
    Silstar's copying Shakespeare's mark entitled Shakespeare to a pre-
    sumption of a likelihood of confusion; (2) whether there was in fact
    a likelihood of confusion; and (3) whether Silstar established its fair-
    _________________________________________________________________
    *While functionality and descriptiveness are distinct concepts in trade-
    mark law, they have the same legal effect on the issues before us. Silstar
    claims that its gray-based and clear-tipped rod represents the natural
    appearance of graphite and fiberglass used in a relationship that takes
    advantage of those materials' properties, and to that extent the appear-
    ance is the product of function. It also claims that the gray base and clear
    tip describe to the consumer the properties of those materials that make
    them suitable for their function, and in that sense the rod's appearance
    is descriptive. Whether the essence of Silstar's position -- and the dis-
    trict court's opinion which agreed with Silstar-- is that it was acting in
    good faith because of its rods' functionality or their descriptiveness need
    not be resolved, because, as we discuss below, either would supply a fac-
    tual basis for a finding of good faith or fair use.
    7
    use defense. We turn to the question of whether functionality or
    descriptiveness is relevant to these issues.
    A
    The presumption that intentionally copying someone else's mark
    causes a likelihood of confusion arises from the recognition that one
    who tries to deceive the public should hardly be allowed to prove that
    the public has not in fact been deceived. See Osem Foods Indus. v.
    Sherwood Foods, Inc., 
    917 F.2d 161
    , 165 (4th Cir. 1990). But that
    presumption arises only when the copier "inten[ds] to exploit the
    good will created by an already registered trademark." AMP, 
    540 F.2d at 1186
     (emphasis added). "A likelihood of confusion should not be
    inferred from proof that the actor intentionally copied the other's des-
    ignation if the actor acted in good faith under circumstances that do
    not otherwise indicate an intent to cause confusion or to deceive."
    Restatement (Third) of Unfair Competition, § 22(2) (1995) (emphasis
    added).
    The district court in this case was thus required to determine
    whether Silstar intended to deceive the public and exploit Shake-
    speare's goodwill. Conversely, it was free to consider as a factual
    matter, whether Silstar copied Shakespeare's rod with the intent of
    reproducing and using a functional aspect, which it was legally enti-
    tled to do. See Bonita Boats, Inc. v. Thundercraft Boats, Inc., 
    489 U.S. 141
    , 164 (1989) (reproducing a functional attribute is a legiti-
    mate competitive activity); Inwood Labs., Inc. v. Ives Labs., Inc., 
    456 U.S. 844
    , 857-58 n.20 (1982) ("[b]y establishing . . . that uniform cap-
    sule colors served a functional purpose, the petitioners offered a legit-
    imate reason for producing an imitative product"); see also
    Restatement (Third) of Unfair Competition, § 22 cmt. c ("If the actor
    reasonably believes that the other's designation is functional . . .,
    proof that the actor intentionally copied the other's designation does
    not justify an inference of confusion"). Accordingly, when the district
    court considered the functional and descriptive aspects of Shake-
    speare's mark in determining whether to presume a likelihood of con-
    fusion, it considered relevant factors.
    B
    Similarly, the district court considered the functional and descrip-
    tive aspects of Shakespeare's marks in determining whether Silstar's
    8
    competing clear-tipped fishing rod was in fact likely to confuse. In
    determining the likelihood of confusion, the court may consider --
    indeed, should consider -- the mark's strength. See Lonestar Steak-
    house & Saloon, Inc. v. Alpha of Virginia, Inc., 
    43 F.3d 922
    , 934-35
    (4th Cir. 1995). Marks may be, in ascending order of strength,
    generic, descriptive, suggestive, or arbitrary. See 
    id. at 933
    .
    In this case when considering the strength of Shakespeare's mark,
    the court concluded that the mark was primarily descriptive, although
    it had some secondary meaning. See Shakespeare III, 906 F. Supp. at
    1013. The court found that the mark carries very little secondary
    meaning since the functional aspects of the clear tip, rather than its
    source-identifying power, were emphasized in marketing. See id. In
    considering the functional or descriptive nature of the mark in this
    context, the court was simply following the factors already estab-
    lished earlier by this court. See Perini Corp. v. Perini Const., Inc.,
    
    915 F.2d 121
    , 127 (4th Cir. 1990) (including strength of mark as a
    factor courts should consider); Pizzeria Uno Corp. v. Temple, 
    747 F.2d 1522
    , 1527 (4th Cir. 1984) (same).
    C
    Finally, in resolving whether Silstar established a fair-use defense,
    the district court considered the functional and descriptive aspects of
    Shakespeare's mark. It concluded that functionality was a relevant
    factor where a party "in good faith and not as a means of source-
    identification [seeks] . . . to use a functional feature of a product
    which another party . . . has registered as a trademark." Shakespeare
    III, 906 F. Supp. at 1016. The district court had also previously noted
    that a clear-tip on a fishing rod demonstrates that the tip has strength
    because of its solid fiberglass construction. See Shakespeare I, 
    802 F. Supp. at 1391
    . The clarity was found to be a natural characteristic of
    solid fiberglass used in fishing rod tips, see 
    id.,
     and such tips are
    undoubtedly functional. Thus, clarity is merely descriptive of a func-
    tional aspect of the rod. While such descriptive features would not
    normally be entitled to any trademark protection, the district court
    correctly noted that the mark had acquired some secondary meaning,
    entitling it to protection. But because clarity was a natural and
    descriptive characteristic of the rod's functional tip, the district court
    concluded that Silstar did not act in bad faith, but had a legitimate
    9
    non-predatory reason for giving its solid fiberglass tips a clear appear-
    ance. See Shakespeare III, 906 F. Supp. at 1010, 1015-16.
    In Inwood Labs, the Supreme Court concluded that color could
    serve an identifying function, which gave a good faith reason for imi-
    tation. See 
    456 U.S. at
    857-58 n.20. There, the court accepted the dis-
    trict court's conclusions that a drug's color could function to identify
    its therapeutic affects. 
    Id.
     Similarly, the district court, in deciding
    whether Silstar acted in good faith, considered clarity of fishing rod
    tips as identifying or describing the rod's construction. See
    Shakespeare III, 906 F. Supp. at 1015-16. To identify the rods' con-
    struction is a legitimate, nonpredatory purpose which tends to show
    a good-faith motivation for copying, which is an element of the fair-
    use defense. Identifying the clear tip's functional and descriptive
    nature was thus relevant to the court's inquiry.
    III
    Shakespeare next challenges the district court's conclusion that Sil-
    star's sale of its Power Tip Crystal rods would not likely cause confu-
    sion with Shakespeare's Ugly Stik rods. Shakespeare contends that
    the district court (1) improperly denied it the presumption of a likeli-
    hood of confusion that flows from intentional copying and (2) clearly
    erred in finding as a fact that Shakespeare had not established a likeli-
    hood of confusion. We will address these points in order.
    A
    Whether Shakespeare was entitled to a presumption of a likelihood
    of confusion involves a question of law which we review de novo.
    Because the district court found that Silstar "had knowledge of, and
    essentially copied, Shakespeare's trademark," Shakespeare III, 906 F.
    Supp. at 1010, Shakespeare argues that the law of this circuit requires
    the court to have presumed that confusion was likely.
    In Osem Food, we recognized that a presumption of a likelihood
    of confusion is appropriate in some circumstances:
    When a newcomer to the market copies a competitor's
    trade dress, its intent must be to benefit from the goodwill
    10
    of the competitor's customers by getting them to believe
    that the new product is either the same, or originates from
    the same source as the product whose trade dress was cop-
    ied. Logic requires, no less than the presumption of second-
    ary meaning from copying, that from such intentional
    copying arises a presumption that the newcomer is success-
    ful and that there is a likelihood of confusion.
    
    917 F.2d at 165
    . Our cases make clear, however, that that presump-
    tion arises only where the intentional copying is motivated by an "in-
    tent to exploit the good will created by an already registered
    trademark," AMP, 
    540 F.2d at 1186
    . We noted explicitly in Osem
    Food that a court should "require one who tries to deceive customers
    to prove that they have not been deceived." 
    917 F.2d at 165
     (emphasis
    added); see also Polo Fashions, Inc. v. Craftex, Inc., 
    816 F.2d 145
    ,
    148 (4th Cir. 1987) ("[w]here . . . one produces counterfeit goods in
    an apparent attempt to capitalize upon the popularity of, and demand
    for, another's product, there is a presumption of a likelihood of con-
    fusion") (emphasis added); Allen v. Standard Crankshaft & Hydraulic
    Co., 
    323 F.2d 29
    , 36 (4th Cir. 1963) ("an apparent motive of the
    junior party to create confusion and to give to his goods a superficial
    appearance of being those of the senior party is properly considered").
    In contrast, where the owner of the junior mark essentially copies a
    mark with no intent to exploit the senior mark's goodwill -- such as
    to describe a functional aspect of the product -- the party claiming
    infringement must prove the likelihood of confusion without the ben-
    efit of a presumption. See Restatement (Third) of Unfair Competition,
    § 22(2) (1995) ("[a] likelihood of confusion should not be inferred
    from proof that the actor intentionally copied the other's designation
    if the actor acted in good faith under circumstances that do not other-
    wise indicate an intent to cause confusion or to deceive"). Thus,
    Shakespeare is entitled to the presumption of a likelihood of confu-
    sion only if Silstar's intent is to free-ride on Shakespeare's goodwill.
    The district court concluded as a factual matter that "it is equally
    clear from the evidence presented at trial that Silstar's intent was not,
    and is not, to capitalize on, or otherwise exploit, Shakespeare's trade-
    mark." Shakespeare III, 906 F. Supp. at 1010. Indeed, although Silstar
    used a clear tip, the district court concluded that it had taken care to
    distinguish the overall appearance of its rods so consumers would not
    11
    confuse Silstar's Power Tip Crystal rod for Shakespeare's Ugly Stik
    rod. See id. at 1011. Although we readily acknowledge that a fact-
    finder could have concluded that Silstar intended to free-ride on
    Shakespeare's goodwill, we cannot conclude that the district court's
    contrary finding is clearly erroneous.
    Even if Shakespeare were entitled to the presumption, the district
    court found that Silstar had introduced sufficient evidence to rebut the
    presumption (returning the burden of persuasion to Shakespeare) and
    to entitle the court to find that there was no likelihood of confusion.
    See id. at 1011 n.17. Again, we cannot conclude that the district court
    was clearly erroneous in finding that Silstar had presented enough
    evidence to rebut a presumption of the likelihood of confusion.
    B
    Shakespeare contends further that, in any event, the court clearly
    erred in holding that it had not factually established a likelihood of
    confusion. Whether Silstar's Power Tip Crystal rod is likely to cause
    confusion with Shakespeare's Ugly Stik rod, so that an appreciable
    number of the public attribute Silstar's product to Shakespeare, is "an
    inherently factual issue that depends on the facts and circumstances
    in each case." Lonestar Steak House, 
    43 F.3d at 933
     (internal quota-
    tions omitted). In resolving that factual question, a district court must
    consider any factor relevant to whether confusion is likely between
    the two marks. See Durox Co. v. Duron Paint Mfg. Co., 
    320 F.2d 882
    ,
    885 (4th Cir. 1963). We review the district court's findings for clear
    error. See Pizzeria Uno, 
    747 F.2d at 1526
    .
    We have, over the course of several cases, developed factors for
    courts to consider in determining the likelihood of confusion. They
    include (1) the strength or distinctiveness of the mark; (2) the simi-
    larity of the two marks; (3) the similarity of the goods or services
    which the marks identify; (4) the similarity of the facilities used by
    the parties in conducting their businesses; (5) the similarity of adver-
    tising used by the parties; (6) the defendant's intent in using the
    mark; (7) actual confusion; (8) the proximity of the products as they
    are actually sold; (9) the probability that the senior mark owner will
    "bridge the gap" by entering the defendant's market; (10) the quality
    of the defendant's product in relationship to the quality of the senior
    12
    mark owner's product; and (11) the sophistication of the buyers. See,
    e.g., Perini, 
    915 F.2d at 127
    ; Pizzeria Uno, 
    747 F.2d at 1527
    . The list
    of these factors, however, is neither exhaustive nor exclusive, and
    some of the factors may not always be relevant or equally emphasized
    in each case. See Anheuser-Busch Inc. v. L & L Wings, Inc, 
    962 F.2d 316
    , 320 (4th Cir. 1992); Durox, 
    320 F.2d at 885
    . We articulate them
    to focus an inquiry that must be tailored to the factual circumstances
    of each case.
    In resolving this case, the district court applied each of the Pizzeria
    Uno/Perini factors, concluding that while a larger number of factors
    favored Shakespeare, the more relevant and weighty factors favored
    Silstar. Thus the court found that (1) the mark's strength, which
    somewhat favored Shakespeare, nevertheless had little power in iden-
    tifying its source, see Shakespeare III, 906 F. Supp. at 1012-13;
    (2) the marks' similarity was largely negated by overall appearances
    of the rods and the buyers' sophistication, see id. at 1011; (3) the
    fishing rods were found to differ in overall appearance, see id.;
    (4) though Shakespeare and Silstar used similar facilities, the sophis-
    tication of buyers and the marketing of the rods at eye level negated
    the possible confusion that might result, see id.; (5) although the
    companies used similar advertising media, little emphasis was placed
    on the tip as identifying Shakespeare, and the sophistication of buyers
    negated any confusion, see id. at 1012; (6) Silstar's intent did nothing
    to establish the likelihood vel non of confusion, see id. at 1012 n.21;
    (7) actual confusion, even though favoring Silstar, was of limited
    importance because significant distribution of Silstar rods had been
    prevented by preliminary injunction, see id.; (8) although the prod-
    ucts were marketed very close to one another, the overall appearance
    and sophistication of buyers negated any confusion, see id. at 1012;
    (9) "bridging the gap" was of no relevance since the two companies
    were already competitors, see id. at 1012 n.21; (10) since the quality
    of the products was almost identical, a comparison was not helpful,
    see id.; (11) the sophistication of buyers, how they examined the rods
    and what inspection they did before buying, strongly favored Silstar,
    see id. at 1011-13. We can find no clear error in the district court's
    conclusions. Each relevant factor was considered and the weight
    accorded to each factor was reasonably defended.
    13
    IV
    Finally, Shakespeare contends that (1) because it established a
    likelihood of confusion, the district court should not, as a matter of
    law, have considered Silstar's fair-use defense, and (2) in any event
    the court clearly erred in finding as a matter of fact that Silstar's use
    of the clear tip was fair.
    A
    To maintain its argument that a finding of a likelihood of confusion
    legally precludes consideration of the fair-use defense, Shakespeare
    relies on the district court decision in Dayton Progress Corp. v. Lane
    Punch Corp., 
    12 U.S.P.Q.2d 1695
     (W.D.N.C. 1989), and our review
    of the same case, Dayton Progress Corp. v. Lane Punch Corp., 
    917 F.2d 836
     (4th Cir. 1990). We do not agree, however, that these deci-
    sions support Shakespeare's legal position.
    The district court in Dayton Progress concluded that the infringer's
    use of Dayton's product "was not undertaken in good faith and was
    not intended by [the infringer] as a non-trademark use" of the product.
    12 U.S.P.Q.2d at 1708. The court concluded, therefore, that the
    infringer could not rely on the defense of fair use. See 
    id.
     The court
    did not conclude, however, that the likelihood of confusion precluded
    the fair-use defense; rather its finding of bad faith precluded use of
    the defense. On appeal, we so understood the district court's decision,
    observing:
    To establish a fair use defense for these [products], [the
    infringer] must prove that [the products] are used "fairly and
    in good faith" only to describe the punches and that the
    infringing mark is not used as a trademark. Here, the district
    court found that [the infringer's] adoption and use of [the
    marks] was not in good faith.
    Dayton Progress, 917 F.2d at 840 (citations omitted). Because we
    concluded that the district court's finding of bad faith was not clearly
    erroneous, we affirmed the district court's rejection of a fair-use
    defense. See id. We did not, however, hold that a finding of a likeli-
    14
    hood of confusion per se precludes consideration of the fair-use
    defense.
    Beside the fact that our prior cases do not support Shakespeare's
    legal argument, it defies logic to argue that a defense may not be
    asserted in the only situation where it even becomes relevant. If a fair-
    use defense is not to be considered when there is a likelihood of con-
    fusion, then it is never to be considered. The fair-use defense comes
    into play only when infringement -- including a likelihood of confu-
    sion -- has been established. A defense which can be considered only
    when the prima facie case has failed is no defense at all. While it is
    true that to the degree that confusion is likely, a use is less likely to
    be found fair, it does not follow that a determination of likely confu-
    sion precludes considering the fairness of use. The district court cor-
    rectly followed our mandate in Shakespeare II that "any inquiry into
    an alleged `fair use' of the clear tip must be accompanied by an analy-
    sis of the likelihood of confusion among consumers that may be cre-
    ated by Silstar's use of the clear tip." 
    9 F.3d at 1099
    .
    B
    In considering Silstar's fair-use defense, the district court found as
    a fact that Silstar had acted in good faith. The court found expressly
    that Silstar's use of a clear tip was to take advantage of its functional
    and descriptive aspects and not "to use the clear tip as [identifying]
    a source of origin of the rods." Shakespeare I, 
    802 F. Supp. at 1393
    .
    The court continued that "Silstar does not seek to use the clear tip on
    the Power Tip Crystal rod in a trademark sense" but only in its "de-
    scriptive sense." 
    Id. at 1396
    . The district court concluded:
    There is no indication that Silstar's attempt to utilize the
    clear tip is unfair or in bad faith.
    ***
    In this case, there is no alternative design to Shake-
    speare's mark which would be as effective in communicat-
    ing to consumers the fact that the rod is made of a graphite
    base and a solid fiberglass tip since the clear tip and the
    15
    opaque base represent the natural colors of the graphite and
    the fiberglass resin which compose the rod.
    
    Id. at 1396, 1398
    . The court summarized that Silstar sought "in good
    faith and not as a means of source-identification, to use a functional
    feature of a product" which Shakespeare had registered as a mark.
    Shakespeare III, 906 F. Supp. at 1016.
    We cannot conclude that any of these factual findings of the district
    court are clearly erroneous.
    Accordingly, the judgment of the district court is
    AFFIRMED.
    WIDENER, Circuit Judge, dissenting:
    I respectfully dissent.
    As did the district court before it, the majority errs in failing to
    apply this circuit's presumption of confusion to Silstar's deliberate
    copying of the clear tip and opaque base on Shakespeare's "Ugly
    Stik" fishing rods. Shakespeare maintains this color configuration as
    a registered trademark. Both the majority and the district court recog-
    nize that "Silstar had knowledge of, and essentially copied, Shake-
    speare's trademark." Slip op. at 14; Shakespeare Co. v. Silstar Corp.
    of America, Inc., 
    906 F. Supp. 997
    , 1010 (D.S.C. 1995). With that
    acknowledgement, the majority should then proceed to apply the
    mandate of Osem Food Industries v. Sherwood Foods, Inc., 
    917 F.2d 161
     (4th Cir. 1990):
    When a newcomer to the market copies a competitor's trade
    dress, its intent must be to benefit from the goodwill of the
    competitor's customers by getting them to believe that the
    new product is either the same, or originates from the same
    source as the product whose trade dress was copied. Logic
    requires, no less than the presumption of secondary meaning
    from copying, that from such intentional copying arises a
    presumption that the newcomer is successful and that there
    is a likelihood of confusion.
    16
    917 F.2d at 165 (emphasis added). It is patent that the majority simply
    declines to read the phrase "must be" in the above quotation from
    Osem Food. And it can point to no precedent in this circuit requiring
    a showing of something more than intentional copying before the pre-
    sumption arises.* It is thus my opinion that our precedent entitles
    Shakespeare to a presumption of likelihood of confusion.
    Had the district court properly applied this presumption, its find-
    ings of fact may well have been altered. We cannot speculate as to
    what those findings would have been had it employed the correct
    legal standard. Thus, the case should be remanded for such an exami-
    nation.
    With regard to Silstar's fair-use defense, I do not believe such a
    defense is viable if a likelihood of confusion is established. The
    majority would allow a fair-use defense even when there is a likeli-
    hood of confusion, and states that it "defies logic" to hold otherwise.
    Slip op. at 15. I disagree. A leading commentator has explained the
    logical relationship between fair use and likelihood of confusion as
    follows: "The better view is that it is inconsistent to find both likely
    confusion and a fair use. Rather, `fair use' should be viewed as
    merely one type of use which is not likely to cause confusion and
    hence is a `defense' only in that sense." 1 J. Thomas McCarthy,
    McCarthy on Trademarks and Unfair Competition§ 11:47 (4th ed.
    1996).
    The majority's holding would place this circuit in the minority of
    courts that permit a fair-use defense even if a likelihood of confusion
    exists. See 1 McCarthy, supra, § 11:47 n.2 (citing cases allowing fair-
    use defense even when likely confusion shown). I do not believe such
    a departure is warranted, or even permissible under circuit precedent.
    _________________________________________________________________
    *The majority refers to several cases allowing a presumption of confu-
    sion when there has been proof of intent to exploit the good will created
    by an already registered trademark. Slip op. at 10-11. These cases, how-
    ever, do not directly address the effect of intentional copying and, at any
    rate, do not hold that intent to exploit is the only means of establishing
    a likelihood of confusion.
    17
    In Dayton Progress Corp. v. Lane Punch Corp., 
    917 F.2d 836
     (4th
    Cir. 1990), we affirmed a district court which, after holding that a
    likelihood of confusion existed, held that "[defendant] cannot now
    rely on the defense of `fair use' to justify its use of [plaintiff's] trilit-
    eral product designators." Dayton Progress Corp. v. Lane Punch
    Corp., 
    12 U.S.P.Q.2d 1695
    , 1708 (W.D.N.C. 1989). Although the
    majority states that the district court's finding of bad faith, rather than
    its finding of likelihood of confusion, precluded the fair-use defense
    in Dayton Progress, that statement by the majority is hardly accurate
    because the Dayton Progress district court's finding of bad faith was
    based on the defendant's exact copying and identical use of the plain-
    tiff's product. 12 U.S.P.Q.2d at 1708. On appeal, we concluded that
    the district court's finding of bad faith was not clearly erroneous, and
    hence we accepted the district court's factual basis for that determina-
    tion. Dayton Progress, 
    917 F.2d at 840
    . Read in conjunction with the
    district court's decision, as it must be, our Dayton Progress opinion
    supports the position that it is inconsistent to find both a likelihood
    of confusion and a legitimate fair-use defense when intentional copy-
    ing has occurred.
    Thus, the majority opinion adopts the minority view of the authori-
    ties, that a fair-use defense is available even in the face of intentional
    copying, and declines to follow the circuit precedent of Dayton
    Progress.
    Finally, I should add that the penultimate rationale in the majority
    opinion, slip op. at 16, is:
    The [district] court summarized that Silstar sought "in good
    faith and not as a means of source-identification, to use a
    functional feature of a product" which Shakespeare had reg-
    istered as a mark. Shakespeare III, 906 F.Supp. at 1016.
    While the majority concludes that that factfinding is not clearly
    erroneous, in my opinion it is inherently incredible.
    Accordingly, I would vacate the judgment of the district court and
    remand this case for the district court to make its factual findings after
    applying the presumption of likelihood of confusion. I would also
    18
    require the district court to correctly apply the rule with respect to a
    fair-use defense, as I have discussed above.
