The complaint by Door Systems, Inc., in two counts (actually more, but the others have been abandoned), charged Pro-Line Door Systems, Inc. with infringing the plaintiffs registered trademark “Door Systems” in violation of section 32 of the Lanham Act, 15 U.S.C. § 1114(1), and with false designation of origin in violation of section 43(a), 15 U.S.C. § 1125(a). The district court granted summary judgment for the defendant on both counts, holding with respect to the first that the term “door systems” is generic and therefore cannot be trademarked and with respect to the second that likelihood of confusion between the defendant’s product and the plaintiffs was nil.
Both parties sell overhead garage doors together with the electrical device for opening and closing them remotely. Since 1980, the plaintiff has advertised (mainly in the yellow pages) and sold its garage doors and control devices under the trademark “Door Systems,” which the Patent and Trademark Office accepted for registration in 1989. The defendant started in business in 1986, under the name “Pro-Line Door Systems, Inc.” Four other sellers of automatic garage doors also began using the term “door systems” sometime after 1980. Door Systems sued all five in this lawsuit, settling with all but Pro-Line in consent decrees that bar those sellers from continuing to denote their brands by the term.
The function of the normal product trademark is to identify a brand, so that consumers who want to buy a particular brand of the product will know which brand it is when they are shopping for the product. Mumm’s, the brand, is a trademarked brand

of champagne, the product. A generic term, in the jargon of trademark law, is a word that denotes the product rather than any of the brands of the product.
Two Pesos, Inc. v. Taco Cabana, Inc.,
One question presented by Pro-Line’s defense is thus whether “door systems” is the name of the product-automatic garage doors, or remotely controlled garage doors, or remotely controlled doors of any type, or perhaps any system of noncontiguous parts for performing the function of a door (for example, a matching pair of screen door and regular door, or an integrated system of French doors for a patio or sun-room)-that subsumes the particular brands sold by the parties. This is a question of fact,
Bath & Body Works, Inc. v. Luzier Personalized Cosmetics, Inc.,
More precisely, the question of genericness is one of linguistic usage, and can be approached by a variety of routes. One is the dictionary. If the term “door systems” appeared in a standard dictionary in lower case, this would be powerful evidence that the term was generic, because nouns and other nominatives listed in dictionaries, save for the occasional proper name, denote kinds rather than specific entities (“dog,” not “Fido”). The term “door systems” does not appear in the dictionary. Its component words do, of course, but that in itself cannot count for much; otherwise it could be argued that “Seven-Up” is generic, which no one believes. (Well, almost no one-the argument that it is was made in
Seven-Up Co. v. Bubble Up Corp.,
50 C.C.P.A 1012,
The fact that the parties’ product is designated by a general term that is not the alleged generic term bears against Pro-Line’s defense, because it shows that Pro-Line will not be rendered speechless, as it were, if forbidden to describe its product by the term “door systems.”
Blau Plumbing, Inc. v. S.O.S. Fix-It, Inc., supra,
There was somewhat more evidence in
Liquid Controls Corp. v. Liquid Control Corp.,
Granted, “door systems,” like “liquid controls,” is a good
description
of what the parties sell. But a descriptive term that is not the name of the product (“temperature feedback control” versus “thermostat”) can be trademarked if it acquires secondary meaning,
Spraying Systems Co. v. Delavan, Inc., supra,
A trademark search conducted by Pro-Line revealed that at least a dozen firms (mainly but not only sellers of garage doors), in addition to the five garage-door sellers sued by Door Systems, denote their product by the term “door systems.” If anything, one is surprised the number is no larger. The popularity of the word “system” in contemporary noun expressions (“weapon systems,” “stereo systems,” “alarm systems,” and so forth) makes it plausible to suppose that “door system” might catch on as the standard term for remotely controlled or otherwise complex devices for performing the door function. Perhaps it has caught on already in the relevant submarkets. We do not mean to suggest that the evidence is wholly onesided in the plaintiffs favor. Nor can the plaintiff obtain any residual mileage from the registration of its trademark. The presumption of validity that federal registration confers (see 15 U.S.C. § 1115(a)) evaporates as soon as evidence of invalidity is presented.
Liquid Controls Corp. v. Liquid Control Corp., supra,
Summary judgment is not to be used to resolve evidentiary conflicts, but merely to identify their presence or absence. Fed.R.Civ.P. 56;
Waldridge v. American Hoechst Corp.,
We need not decide, however, whether the issue of the generic status of “door systems” could properly be resolved on summary judgment, given the record compiled in the pretrial proceedings. It is plain that Door Systems could not prevail on the first count even if we remanded for a trial on the issue of genericness. The reason has to do with the ground on which the district court dismissed the second count, which alleges that purchasers of Pro-Line’s garage doors are likely to be misled by the use of the words “door systems” in its advertising into thinking they’re buying from Door Systems. This charge is separable from the first because even if “door systems” is generic a competitor might use the term in its advertising or labeling in such a way as to mislead the consumer.
Liquid Controls Corp. v. Liquid Control Corp., supra,
But a glance at the parties’ ads, which we reproduce in an appendix to this opinion, suffices here as in
Libman Co. v. Vining Industries, Inc.,
We acknowledge the pitfalls of basing a judgment of likelihood of confusion on a side-by-side comparison of the parties’ advertisements. See
Libman Co. v. Vining Industries, Inc., supra,
In the district court Pro-Line argued that the absence of evidence of likelihood of confusion was not only a ground for knocking out the second count but also an alternative ground for knocking out the first count. A trademark, even a registered one, is not a property right, like a copyright or a patent, but merely an identifier of source. Others can use the same mark to identify their product, provided there is no likelihood of confusion, 15 U.S.C. § 1114(1); 3 McCarthy,
supra,
§ 23.01[1], which would impair the trademark’s function as an identifier. The district court, having found that Door Systems’ mark could not be trademarked at all, did not proceed to the alternative ground that there was no likelihood of confusion. Pro-Line could nevertheless have defended the district court’s judgment on the alternative ground in this court. An appellee can defend the judgment appealed from on any nonwaived ground, even if the district court did not address it.
Massachusetts Mutual Life Ins. Co. v. Ludwig,
' So if we remanded the case for further proceedings on the first count, because we were not satisfied that the district court should have granted summary judgment for the defendant on the ground that “door systems” is a generic term, Pro-Line would be free to advance as an alternative defense the unlikelihood of confusion and to point out that the finding of unlikelihood of confusion was the law of the case and should not be reexamined by the district court. The district court would grant judgment for the defendant, and we would affirm, for at argument Door Systems’ lawyer conceded that the finding of unlikelihood of confusion on count two, if sustained, would equally bar any relief on count one. Since the outcome of a remand is foreordained, and the appellant cannot claim unfair surprise because the.issue was explored at the argument and the appellant did not seek an opportunity for supplementary briefing (which would surely have been futile: the issue is open and shut), ordering a remand would be a waste of time.
Affirmed.
