Opinion

JOHN P. MOORE, Circuit Judge.

Coherent, Inc., (Coherent) filed suit against Coherent Technologies, Inc., (Coherent Technologies) alleging trademark infringement and false designation of origin under 15 U.S.C. §§ 1114 and 1125(a) (1988), and unfair competition under Colorado common law. The district court ruled against Coherent after a bench trial, deciding that Coherent Technologies’ use of the word “coherent" constituted a fair use and was not likely to cause confusion. Coherent, Inc. v. Coherent Technologies, Inc., 736 F.Supp. 1055 (D.Colo.1990). Because we affirm the district court’s holding that there is no likelihood of confusion, Coherent has failed to establish any of its claims. Therefore, we need not address the fair use defense to infringement.

I

This dispute stems from the use of the word “coherent” by two companies which work with laser technology. The U.S. Trademark Trial and Appeal Board defined the word when it granted Coherent’s first trademark registration: “ ‘[CJoherent’ means the light waves or photons are not scattered or random but are in phase in frequency and spatial relationship. It is the coherency of the radiation which results in the highly concentrated energy that makes lasers useful in a great variety of applications.” The district court found *1124 that all lasers emit coherent light to some degree, and the term is commonly used descriptively in the scientific community. That determination is not challenged on appeal.

Coherent has been manufacturing lasers and laser systems and offering services related to the use of its products since 1966. It is headquartered in Palo Alto, California, and has a subsidiary, Coherent General, in Sturbridge, Massachusetts. The company has used “COHERENT” as a trademark on goods in interstate commerce since April 3, 1973, and obtained its first federal registration of the mark on June 13, 1978. Five of Coherent's six registrations have become incontestable through continuous use for five years. 15 U.S.C. § 1065. Over the years, Coherent has spent between $200-250 million to promote products under the “COHERENT” name and mark. By dollar volume of lasers sold, Coherent occupies about twenty percent of the worldwide market.

Coherent Technologies was incorporated in 1984 and is located in Boulder, Colorado. It develops and markets coherent laser radar systems, known as lidar systems, for atmospheric sensing and target tracking, ranging, and imaging. Coherent Technologies uses lasers, such as those produced by Coherent, as components in its systems but does not produce lasers itself. Coherent Technologies does not affix its corporate name to any product. At the time of trial, it had completed one project.

II

To properly analyze this case, we first clarify the legal significance of “COHERENT” as an incontestable mark. The district court cited a portion of 15 U.S.C. § 1115(b), which provides:

To the extent that the right to use the registered mark has become incontestable under Section 1065 of this title, the registration shall be conclusive evidence of the validity of the registered mark and of the registration of the mark, of the registrant’s ownership of the mark, and of the registrant’s exclusive right to use the registered mark in commerce. Such conclusive evidence shall relate to the exclusive right to use the mark on or in connection with the goods or services specified in the affidavit filed under the provisions of said Section 1065....

Describing this as an evidentiary presumption, the district court then proceeded to analyze the fair use defense, one of the enumerated defenses to use of an incontestable mark. 15 U.S.C. § 1115(b)(4). Concluding that Coherent Technologies had established fair use, the district court stated Coherent “may not rest on the incontestability of its trademarks and service marks to prove infringement.” Coherent, Inc., 736 F.Supp. at 1063. Next, the court found no likelihood of confusion under § 1114, which sets forth the elements of an infringement cause of action. 1 By addressing the issues in this order, the district court left unclear the relationship between incontestable status and the need to show likelihood of confusion.

We conclude that a plaintiff with an incontestable mark must still show likelihood of confusion as an element of an infringement claim. Incontestability establishes a plaintiff’s right to use a trademark, subject only to certain enumerated defenses. 15 U.S.C. §§ 1115(b)(1)—1115(b)(8). However, it does not mean that any use by *1125 another party automatically constitutes infringement. Congress amended § 1115(b) in 1988, adding the clause, “[s]uch conclusive evidence of the right to use the [incontestable] registered mark shall be subject to proof of infringement as defined in section 1114.” The revision clarified that “incontestability does not relieve the owner of an incontestable registration from the burden of proving likelihood of confusion.” S.Rep. No. 515, 100th Cong., 2d Sess. 38, reprinted in 1988 U.S.Code Cong. & Admin.News 5577, 5601; see also 2 J. Thomas McCarthy, Trademarks and Unfair Competition § 32:44, at 764 (2d ed.1988). We implicitly took this approach in Beer Nuts, Inc. v. Clover Club Foods Co., 805 F.2d 920 (10th Cir.1986), in which we analyzed likelihood of confusion to decide whether an incontestable mark had been infringed. 2 Because incontestability does not eliminate Coherent’s burden of proving likelihood of confusion to establish infringement, we resolve this issue before considering Coherent Technologies’ fair use defense.

Ill

Likelihood of confusion is a question of fact. Beer Nuts, 805 F.2d at 923 n. 2. Reviewing the district court’s decision under the clearly erroneous standard, we affirm the finding of no likelihood of confusion.

We identified several factors relevant to likelihood of confusion in Beer Nuts, emphasizing that no one factor is determinative and the list is not exhaustive:

(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 pictures or designs involved;
(iv) suggestion;
