Lead Opinion
MOORE, J., delivered the opinion of the court, in which MARTIN, J., joined.
KENNEDY, J. (pp. 553-56), delivered a separate opinion concurring in part and dissenting in part.
OPINION
This is an interlocutory appeal of an injunction granted in a trademark case. The parties agree that the mark purports to include at least the two-dimensional guitar shape set out in the trademark-registration papers. However, they disagree as to whether the mark extends to cover three-dimensional objects where two dimensions of those objects have the same general shape (but not the same exact proportions) as the drawing in the registration papers, and as to whether the mark includes additional product features shown in a photograph accompanying the registration papers.
With respect to Gibson’s trademark-infringement claim, we REVERSE the district court’s decision granting summary judgment in favor of Gibson, REVERSE the district court’s decision denying summary judgment in favor of PRS, and VACATE the permanent injunction issued by the district court. We REMAND the case to the district court with instructions that summary judgment be entered in favor of PRS on Gibson’s trademark-infringement claim.
I. BACKGROUND
A. Facts
Certain basic facts are not in dispute. Gibson and PRS both manufacture high-quality guitars. Gibson has been in the business of manufacturing musical instruments for over 100 years. PRS founder Paul Reed Smith (“Smith”) began manufacturing custom guitars in the mid-1970s and opened a guitar factory in 1985.
Gibson introduced at least one guitar model under the Les Paul name in 1952. Since that time, Gibson has offered a number of guitar models under the Les Paul name. At least some of these models were solid-body, single-cutaway electric guitars of the type at issue in this litigation.
PRS is a relatively recent entrant to the solid-body, single-cutaway electric-guitar market. Although PRS had previously manufactured a number of other guitars, it did not offer a single-cutaway guitar in its normal line until January 2000 at the earliest. In February 2000, PRS displayed models of the PRS Singlecut, a solid-body, single-cutaway electric guitar, at a music industry trade show.
B. Procedural History
The procedural posture of this case is somewhat unusual. We briefly summarize those aspects relevant to this interlocutory appeal. On November 6, 2000, Gibson sued PRS in federal district court in Nashville, Tennessee. The complaint sought injunctive relief, costs, attorney fees, and treble damages for trademark infringement, counterfeiting, false designation of origin, and dilution under the Lanham Act, 15 U.S.C. §§ 1114(1), 1125(a), 1125(c), and for unfair competition, fraud, and deceptive business practices under state law. PRS counterclaimed, seeking declaratory and injunctive relief and asserting that: (1) the LP Trademark is invalid and unenforceable; (2) the LP Trademark is not infringed by the PRS Singlecut; (3) any trade dress associated with the Gibson Les Paul series of guitars cannot be protected under the Lanham Act or is otherwise unenforceable; and (4) the PRS Singlecut guitar does not infringe any such trade dress.
PRS moved for summary judgment on all claims and counterclaims, and Gibson moved for partial summary judgment on the trademark-infringement claim. On January 22, 2004, the district court granted Gibson’s motion for partial summary judgment on its trademark-infringement claim and denied PRS’s motion for summary judgment in its entirety. Gibson Guitar Corp. v. Paul Reed Smith Guitars, LP,
This is hereby ORDERED that the Defendant Paul Reed Smith, its partners, employees, agents and all persons in active consent with them are ENJOINED from manufacturing, selling, or distributing, or in any manner[] enabling or aiding others to manufacture, or to sell, or to distribute the PRS Sin-glecut guitar and all versions thereof, including but not limited to their exteri- or shapes and features, the designs of which have been determined to violate Plaintiffs rights to protection under the Lanham Act for its incontestable trademark registration, No. 1,782,606 for Les Paul guitar.

II. ANALYSIS
A. Jurisdiction
The district court had jurisdiction over the underlying action pursuant to the Lanham Act, 15 U.S.C. § 1114. As the district court entered a permanent injunction against PRS, we have jurisdiction to hear this interlocutory appeal pursuant to 28 U.S.C. § 1292(a)(1). Although our jurisdiction arises from PRS’s interlocutory appeal of the permanent injunction entered below, we may also review the district court’s summary judgment rulings because those rulings form the basis for the district court’s decision to order injunctive relief.
In determining whether a district court has properly granted a permanent injunction, we review factual findings for clear error, legal conclusions de novo, and the scope of injunctive relief for abuse of discretion. Worldwide Basketball and Sport Tours, Inc. v. Nat’l Collegiate Athletic Ass’n,
Summary judgment should be granted whenever “there is no genuine issue as to any material fact and ... the moving party is entitled to a judgment as a matter of law.” fed. R. Civ. P. 56(c). On a motion for summary judgment in a trademark-infringement case, we conduct de novo review of both (1) the district court’s determination of what material facts are in dispute; and (2) the legal conclusions the district court drew from the undisputed facts. Jet, Inc. v. Sewage Aeration Sys.,
C. The Scope of the LP Trademark
Prior to conducting our substantive inquiry, we take this opportunity to clarify a fundamental issue. The district court appears to have confused trademark law and trade-dress law when it concluded that the LP Trademark covered the entire guitar, rather than the two-dimensional silhouette included in the registration papers, Gibson I,
To establish trademark infringement within the meaning of the Lanham Act, Gibson must demonstrate that the PRS Singlecut “is likely to cause confusion among consumers regarding the origin [of the Singlecut].” Daddy’s Junky Music Stores, Inc. v. Big Daddy’s Family Music Ctr.,
The district court concluded that, with the exception of actual confusion (factor four), all factors on which it made a finding favored Gibson for summary judgment purposes.
1. Gibson’s Theories of Purchaser Confusion
Gibson argues that despite the lack of actual confusion at the point of sale, the district court’s decision can be affirmed under a theory of either initial-interest confusion (the theory relied on by the district court), post-sale confusion, or some combination of the two. Initial-interest confusion takes place when a manufacturer improperly uses a trademark to create initial customer interest in a product, even if the customer realizes, prior to purchase, that the product was not actually manufactured by the trademark-holder. See PACCAR Inc. v. TeleScan Techs., L.L.C.,
a. Initial-Interest Confusion
The one case where we arguably have applied initial-interest confusion involved facts strikingly different than those involved in the present dispute. In PACCAR, we were faced with a dispute between Telescan, a company operating
b. Post-Sale Confusion
The one published case where we have applied post-sale confusion is also clearly distinguishable from the present ease. Esercizio, a trade-dress case, involved Ferrari sports cars which were manufactured in deliberately limited quantities “in order to create an image of exclusivity.” Esercizio,
c. Gibson’s Smoky-Bar Theory of Confusion
Finally, Gibson argues that, taken together, the initial-interest-confusion and post-sale-confusion doctrines should be extended to include something that we can only describe as a “smoky-bar theory of confusion.” Initial-interest-confusion doctrine, which we have already rejected on the facts of this case, applies when allegedly improper use of a trademark attracts potential purchasers to consider products or services provided by the infringer. Post-sale-confusion doctrine, which we have also rejected on the facts of this case, applies when allegedly improper use of protected trade dress on a lower-quality product diminishes the reputation of the holder of the rights to that trade dress.
In the context of guitar sales, initial interest confusion is of real consequence. Guitar manufacturers know that they can make sales by placing their guitars in the hands of famous musicians. On a distant stage, a smoky bar, wannabe musicians see their heroes playing a guitar they then want.
Gibson Br. at 20-21. As Gibson concedes that PRS produces high-quality guitars, we do not believe such an occurrence could result in confusion harmful to Gibson. If a budding musician sees an individual he or she admires playing a PRS guitar, but believes it to be a Gibson guitar, the logical result would be that the budding musician would go out and purchase a Gibson guitar. Gibson is helped, rather than harmed, by any such confusion.
2. The Summary Judgment Motions
We have determined as a matter of law that initial-interest confusion, post-sale confusion, and Gibson’s “smoky-bar theory of confusion” cannot be used to demonstrate infringement of the trademark at issue in this case. Gibson has conceded that point-of-sale confusion does not occur between these high-priced guitars, and our review of the record does not suggest otherwise. Accordingly, there is simply no basis on which Gibson can show confusion that would demonstrate trademark infringement in violation of the Lanham Act. See KP Permanent Make-Up, Inc. v. Lasting Impression I, Inc.,
III. CONCLUSION
With respect to Gibson’s trademark-infringement claim, we REVERSE the district court’s decision granting summary judgment in favor of Gibson, REVERSE the district court’s decision denying summary judgment in favor of PRS, and VACATE the permanent injunction issued by the district court. We DENY all other claims and motions AS MOOT, and REMAND the case to the district court with instructions that summary judgment be entered in favor of PRS on Gibson’s trademark-infringement claim.
Notes
. We emphasize that this dispute is only over whether the product shape and features are covered by trademark law. All trade-dress claims have been voluntarily dismissed by the parties.
. On appeal, Defendant-Appellant Paul Reed Smith Guitars, LP ("PRS”) also maintains that the district court erred in failing to declare Trademark Registration No. 1,782,606 (the "LP Trademark”) invalid under the doctrines prohibiting protection of functional or generic marks. As we have determined that the LP Trademark, even if valid, is not infringed by the PRS Singlecut, we DENY PRS’s counterclaims against the validity of the trademark AS MOOT. We also note that following oral argument and prior to our decision in this case, PRS filed a motion to stay proceedings in the district court pending the resolution of this appeal. We now DENY this motion AS MOOT.
. On appeal, neither party challenges the district court’s description of the Les Paul single-cutaway guitar produced by Plaintiff-Appellee Gibson Guitar Corp. ("Gibson”):
Gibson's Les Paul single cutaway guitar is a traditionally shaped guitar with a portion removed from [the] body of the guitar where the lower section of the fingerboard meets the body of the guitar. The term "cutaway guitar” denotes that portion of the guitar between the neck and its lower[ ] part, that appears to be missing from the natural, rounded body contour. The removal of this portion forms what is often referred to as the "horn.” One aspect of this horn design is that the musician can access higher strings [and] position[s].
As to other parts of a guitar, a pickup selector switch allows the player to change quickly the electromagnetic inputs to any one of three options: the pickup closest to the neck (the "neck pickup”), the one furthest from the neck (the "bridge pickup”), or a combination of both. The combination of volume and tone knobs for each pickup[] allow[s] the player to set the tone and volume of each pickup and[ ] switching among these pickups can achieve different sounds.
Gibson Guitar Corp. v. Paul Reed Smith Guitars, LP,
. The PRS Singlecut includes numerous source-indicating features, including "the PRS headstock, logo, fretboard inlay, three-dimensional 'scoop' carve in the cutaway which indicates manufacture by PRS, and hanging tags attached to the guitar at shipment and used at point of sale." Joint Appendix ("J.A.”) at 1163 (PRS Reply to Gibson Response to PRS Statement of Undisputed Facts).
.Explaining its decision to issue an injunction prior to the trial on appropriate relief, the district court noted:
Here, the Court did not initially award injunctive relief in contemplation of a motion to alter or amend its earlier findings and conclusions of law for potential error. The Court was of the view that the declaration of rights was sufficient in the interim. PRS did not file a Rule 59 motion or a motion to reconsider. The Court is now firmly convinced that injunctive relief to bar the production and sale of PRS's Sin-glecut is appropriate and necessary.
As to any stay pending an appeal, the standards to consider are those on awarding injunctive relief. For the reasons set forth in the Court's Memorandum, the Court does not believe that PRS will prevail on appeal. Gibson will suffer irreparable injury to its goodwill in its Les Paul[] if PRS is not enjoined. Gibson's dealers would be injured by PRS's unlawful sales of its Singlecut. The Court deems it in the interest of justice to enforce registered trademarks. Given these findings, PRS's request for a stay of injunctive relief will be denied.
Gibson Guitar Corp. v. Paul Reed Smith Guitars, LP,
. A bench trial was held from July 6, 2004 to July 7, 2004. Perhaps awaiting the result of this interlocutory appeal, the district court does not appear to have issued any order following this bench trial.
. See Thornburgh v. Am. Coll. of Obstetricians & Gynecologists,
. The district court’s analysis of this issue reads in full:
The Court follows [In re ECCS, Inc.,94 F.3d 1578 , 1581 (Fed.Cir.1996) ] to conclude that any variations between Gibson’s drawings and the Les Paul guitar are not controlling. The core consideration is whether the Les Paul guitar is covered by Gibson’s trademark. Here, the undisputed facts are that the Gibson's Les Paul guitar is the same shape of the guitar shown in Gibson’s trademark and application papers. Pictures of the Les Paul guitar, as well as pictures from market publications and business records about the Les Paul guitar were part of Gibson's application papers upon which the USTPO issued Gibson’s trade*547 mark registrations. The Court concludes PRS's contention about ... Gibson's drawing lacks merit[.]
Gibson I,
. The issue presented in ECCS was entirely different from the one presented by the LP Trademark. In ECCS, the Federal Circuit was called to determine whether to permit a trademark applicant to amend an admittedly erroneous drawing to conform to its intended trademark, rather than require the trademark be changed to conform to the erroneous drawing. The ECCS trademark applicant had submitted accurate "specimens” of its trademark, as actually used (the word "EXA” appearing above the word "MODULE”), but had included an inaccurate "drawing” of the trademark (listing "EXAMODULE” as a single word, on a single line). ECCS,
. See generally 15 U.S.C. § 1125(a); Wal-Mart Stores, Inc. v. Samara Bros., Inc.,
[t]rade dress refers to the image and overall appearance of a product. It embodies that arrangement of identifying characteristics or decorations connected with a product, whether by packaging or otherwise, [that] make[s] the source of the product distinguishable from another and ... promote[s] its sale. Trade dress involves the total image of a product and may include features such as size, shape, color or color combinations, texture, graphics, or even particular sales techniques.
Abercrombie,
. Many precedents applying this test arise out of bench trials, where the district court has the authority to make findings of fact, see, e.g., Wynn Oil Co. v. Thomas,
This Circuit considers the question of whether there is a likelihood of confusion a mixed question of fact and law. Factual findings must be made with respect to the likelihood of confusion factors set out above. However, the further determination of whether a given set of foundational facts establishes a likelihood of confusion is a legal conclusion. Because this case is presented to us after a grant of summary judgment, our task is to determine whether the District Court correctly held that no genuine issues of material fact were presented regarding the likelihood of confusion factors.
To resist summary judgment in a case where the likelihood of confusion is the dispositive issue, a nonmoving party must establish, through pleadings, depositions, answers to interrogatories, admissions and affidavits in the record, that there are genuine factual disputes concerning those of the Frisch’s factors which may be material in the context of the specific case. Homeowners Group, Inc. v. Home Mktg. Specialists, Inc.,931 F.2d 1100 , 1107 (6th Cir.1991).
. We disagree with several of the district court's conclusions on the individual Frisch factors. However, as these remaining factors are not relevant to our disposition of this case, we need not discuss them separately.
. See Oral Argument Tape, Argument of Behalf of Gibson ("You’re dealing with, you're absolutely right, very sophisticated consumers here. They're sophisticated both at the, at looking for that shape, and they’re sophisticated when they buy this. There's no question when they buy this [i.e., either a PRS Singlecut or a Gibson Les Paul], you’d have to be an idiot not to know which guitar you’re buying. There's labels on it, hang tags, you pay $3000, we understand that.)”; see also Gibson Br. at 15 ("To issue an exemption [from trademark limitations] to PRS for deliberately violating Gibson’s trademark simply because at the point of sale the consumer knows he is buying a 'PRS Les Paul' makes a mockery of trademark protection.”); id. at 24. (“In any case, there is no genuine issue of material fact that PRS’s conduct causes harm, i.e., confusion, in the marketplace. The confusion is simply not at the point of sale."); id. at 41 ("Instead, PRS wants the Court to find that the confusion that occurred was not at the point of sale, and is thus of no consequence.”); id. at 45 ("The expense of the guitar and the degree of savvy of the consumer will likely avoid confusion at the point of sale but will not avoid initial interest confusion.”).
. The dissent maintains that Gibson's concession goes to the ultimate issue of likelihood of confusion, rather than to the fourth factor of the Frisch test. See Dissent at 553-54, nn. 1-2. Although we conclude that the concession is best understood as going to an individual factor, rather than the ultimate issue, we note that even if we were to adopt the dissent's position on this point, it would not lead us to a different result.
. The dissent reads far too much into our discussion of initial-interest confusion in PACCAR Inc. v. TeleScan Techs., L.L.C.,
TeleScan also contends that the district court erred in discounting the disclaimer included on its web sites. The district court found that TeleScan's disclaimer does not remedy the confusion caused by the use of PACCAR's trademarks in its domain names. An infringing domain name has the potential to misdirect consumers as they search for web sites associated with the owner of a trademark. A disclaimer disavowing affiliation with the trademark owner read by a consumer after reaching the web site comes too late. This "initial interest confusion" is recognized as an infringement under the Lanham Act.
Id. at 253 (emphasis added). The three cases we cited in support of the initial-interest-confusion comment in PACCAR are also Internet cases. See id. (citing Eli Lilly & Co. v. Natural Answers, Inc.,
To the contrary, the applicability of the initial-interest-confusion doctrine outside of the Internet context is an issue of first impression in our circuit. Although other circuits have applied the initial-interest-confusion doctrine to find trademark infringement based on use of a deliberately deceptive name or logo, see, e.g., Mobil Oil Corp. v. Pegasus Petroleum Corp.,
The potential ramifications of applying this judicially created doctrine to product-shape trademarks are different from the ramifications of applying the doctrine to trademarks on a product’s name, a company’s name, or a company’s logo. Cf. Versa Prods. Co. v. Bifold Co.,
In response, the dissent suggests that product-shape trademark-holders be required to
Finally, our concerns about the effect of extending the initial-interest-confusion doctrine to product-shape trademarks are particularly relevant in the summary-judgment context. To the extent we allow it to do so, evidence of initial-interest confusion comes into the eight-factor Frisch test as a substitute for evidence of actual confusion. If our belief that nearly all product-shape trademark-holders will be able to show an issue of fact as to whether a competing product creates initial-interest confusion is correct, application of the initial-interest-confusion doctrine in the product-shape context would make it substantially easier for product-shape trademark-holders to survive a defendant’s summary-judgment motion than for plaintiffs alleging any other type of trademark infringement. (Contrary to the dissent’s view, see Dissent at 556 n. 7, product-shape trademark-holders are perfectly capable of protecting their rights without the initial-interest-confusion doctrine: they must simply show, for example, that the marks are sufficiently similar or that purchasers exercise sufficiently little care in choosing a product to show confusion at the point of sale). Given severe anti-competitive effects such a decision could have, we do not believe it is appropriate to extend the initial-interest-confusion doctrine in this manner.
Given the limited fact situation we have before us, we do not go so far as to hold that there is never a circumstance in which it would be appropriate to apply the initial-interest-confusion doctrine to a product-shape trademark. However, we are unable to imagine such a situation at this juncture, and we do hold that the doctrine cannot apply on the facts of this case.
. See, e.g., Playboy Enters., Inc. v. Netscape Communications Corp.,
. We express no opinion on the extent to which trademark law can properly apply to product shapes. Cf. Qualitex Co. v. Jacobson Prods. Co.,
. As post-sale confusion clearly does not apply in this case, we need not decide whether it can ever be properly applied in the context of a trademark claim, rather than trade-dress claim.
Concurrence Opinion
concurring in part and dissenting in part.
I agree that the district court erred in granting summary judgment in favor of Gibson and I also agree that Gibson cannot maintain its trademark infringement claim either on a theory of likelihood of confusion at the point-of-sale (for it has disclaimed that a consumer could be confused at the point-of-sale)
First, this court has recognized initial-interest confusion as an infringement under the Lanham Act. See PACCAR Inc., v. Telescan Technologies, L.L.C.,
The majority’s reason for rejecting the application of initial interest confusion to product shapes is based upon the concern that since many product shapes within the same category will appear similar when viewed from a sufficient distance, if the initial-interest confusion doctrine were applied to product shapes, a product shape trademark holder could prevent competitors from producing even dissimilar products that appeared from a sufficient distance to be somewhat similar to a
Thus, this preliminary question (whether a product shape identifies its source when viewed from the point where the confusion is alleged to have occurred), when in dispute, as it is here, must be addressed before determining if there is an issue of fact as to whether a competitor’s product shape causes initial interest confusion due to its similarity to a trademark holder’s product shape.
Here, PRS argues that, as there are only a few general shapes in which guitars are made, and since there are numerous single-cutaway style guitars in the market, a consumer would not, and, indeed, could not, identify the source of a guitar on the basis of its shape. Although PRS would likely prevail on this issue, I cannot say, in light of the record as developed, that it has met its burden establishing that there is no genuine issue of material fact as to whether the shape of Gibson’s guitar identifies its source.
Since the district court incorrectly analyzed the issue of whether Gibson’s trademark served to identify its source from the distance where the confusion was alleged to have occurred, I would remand for consideration of this issue.
. The majority states, "Gibson’s concession that there is no point-of-sale confusion (which goes to the fourth Frisch factor, actual confusion) is dispositive of Gibson’s claim.” I believe that what is dispositive of any trademark infringement claim brought on a theory of likelihood of confusion at the point-of-sale is not Gibson’s concession of the fourth Frisch factor, which goes to evidence of actual confusion, but rather Gibson's concession that there is no likelihood of consumer confusion at the point-of-sale, which is the ultimate issue to which the Frisch factors are used as a guide to help address when analyzing a trademark infringement claim brought under a theory of likelihood of confusion at the point-of-sale.
. The last sentence of the post-sale confusion section reads, "[P]ost-sale confusion cannot serve as a substitute for point-of-sale confusion in this case." I view the post-sale confusion theory of relief not, when applicable, as serving as a substitute for point-of-sale confusion, but rather as a distinct theory of relief. When the alleged consumer confusion takes place at the point-of-sale, the ultimate issue is likelihood of confusion at the point-of-sale, in which the plaintiff will introduce evidence of point-of-sale confusion. However, when the alleged consumer confusion takes place in the marketplace (post-sale), then the ultimate issue is likelihood of post-sale confusion, in which the plaintiff introduces evidence of post-sale confusion.
. The majority, in footnote 15, explains that PACCAR’s discussion of initial interest confusion was specifically in reference to a dispute over internet-domain names. Obviously, as applied in that case, the doctrine's application related to a company’s name trademark as used in an internet-domain name. All trademarks, whether they be a company’s name, logo, or a product shape, do the same thing: they identify the source of a good. Since we (and many other circuits) have recognized the doctrine, the majority must explain why this recognized doctrine should not apply to trademarked product shapes. I find the majority's explanation unpersuasive.
. The majority repeats its concern underlying its rationale for rejecting the application of initial interest confusion to product shapes in footnote 15 by noting that since many competing products will create initial interest due to their resemblance with a trademarked product shape when viewed from afar, a trademark product shape holder would be able to protect a "penumbra” of more or less similar shapes. If there exists a "penumbra” of products in the marketplace with shapes similar to a trademarked product shape when viewed from afar, then the trademarked product shape would likely fail to identify its source. If there does not exist a "penumbra” of products with shapes similar to a trademarked product shape when viewed from afar, and if the product shape does identify its source when viewed from that vantage point, and if the functionality doctrine does not prevent the application of the initial interest confusion doctrine when such confusion is alleged, then I believe a product shape trademark holder should be able to maintain a trademark infringement claim on the theory of initial interest confusion.
. The majority views this inquiry as "needlessly complicated and unworkable.” I view it as essential. Since, as noted before, the purpose of every trademark is to identify the source of its good, if a trademark does not identify its source, a trademark holder cannot successfully prosecute a trademark infringement claim. If a product shape trademark holder believes that a competitor's product causes confusion as to its source due to the competitor’s products resemblance to the trademark holder’s product shape when viewed from a store's aisle or front-door, then the product shape trademark holder will need to establish that its trademark identifies its source when viewed from those perspectives for any evidence of such confusion to support its claim. Thus, the relevant observation distance or location for determining whether the trademark holder's product shape identifies its source is from whatever distance or loca
It is true, of course, that a product shape trademark holder could argue that a competitor's product causes confusion as to its source when viewed from varying perspectives. Assuming the defendant argues that the trademark holder's product shape does not identify its source when viewed from any of those perspectives, the court will need to address this argument. In this case, the only relevant allegation of initial-interest confusion is from Gibson’s expert, who claimed that upon entering Gruhn's Guitar store in Nashville, he looked at what he thought was a wall of Gibson Les Paul guitars to discover, upon closer inspection, that the guitars were actually PRS Singlecuts. Since PRS argues that Gibson’s guitar shape does not identify its source, Gibson must establish that its shape does identify its source from the perspective where the alleged confusion occurred. Ultimately, Gibson may not be able to succeed in establishing this point, but PRS has not met its burden to be entitled to summary judgment.
. The district court made two fundamental errors with respect to its analysis of this issue. First, the district court improperly considered factors beyond the shape of Gibson's guitar, such as knob placement and color, in determining that Gibson's trademark identified its source, since Gibson's trademark consists only of the shape of the guitar. And second, the district court improperly concluded that since evidence of widespread use of similar marks "is not sufficient to rebut as a matter of law the presumption” that an incontestable mark identifies its source, such evidence "does not warrant further consideration.”
. If the initial interest confusion doctrine were not applicable to product shape trademarks, I believe that product shape trademark holders would be put to a significant disadvantage compared to non-product shape trademark holders since this type of confusion is likely the only type of confusion that could arise with product shapes. It will be the rare case for there to exist a likelihood of confusion with respect to product shape trademarks at the point of sale since any confusion created by a product's similar shape will be dispelled at the point of sale, as most products will have a distinguishing feature that is
