Appeal from the United States District Court for the Northern District of California.
Before MERRILL, GOODWIN, WALLACE, KENNEDY, TANG, SCHROEDER, ALARCON, FERGUSON, NELSON, BOOCHEVER, and NORRIS, Circuit Judges.
MERRILL, Circuit Judge:
[1] Levi Strauss Co. has brought this action against Blue Bell, Inc., seeking damages and injunctive relief for federal trademark infringement,15 U.S.C. § 1114(1982), and false designation of origin,15 U.S.C. § 1125(a) (1982),1and, under CaliforniaPage 1354state law, for trademark infringement, unfair competition and trademark dilution. The claimed trademark is for a pocket tab, which Strauss describes as a folded cloth ribbon sewn in the vertical seam of a "garment patch pocket." Blue Bell is alleged to have violated Strauss's trademark rights by using a horizontal tab, bearing the word "Wrangler" or "Maverick," on the pockets of its shirts.
I
[2] The pocket tab trademark was adopted and put to use by Strauss on September 1, 1936, and on May 10, 1938, registration was granted by the Patent and Trademark Office. The mark was described as "a small marker or tab of textile material or the like, colored red. . . ." The goods in connection with which it was used were stated to be "overalls of the patch pocket type." In subsequent years other tabs in other colors, some bearing the "Levi's" name, have been registered for use on jackets and "garments, particularly trousers."

[3] In 1969 Strauss began using a pocket tab on shirts. An application for registration of a shirt tab bearing the Levi's name has been filed. Blue Bell has filed opposition to that application, and proceedings have been suspended pending the outcome of this litigation. A shirt tab was registered by Strauss under California state law on June 12, 1974. Commencing around 1975, Blue Bell began marketing a shirt bearing a "Wrangler" or "Maverick" label imprinted on a tab consisting of a folded cloth ribbon affixed to the seam of a shirt pocket. It is this use of a shirt pocket tab by Blue Bell that is the subject of this action.

[4] In order to prevail on its federal claims, Strauss must establish both (1) that it has a protected interest (or trademark right) in the pocket tab allegedly infringed by Blue Bell's shirt usages and (2) that Blue Bell's shirt usages are likely to cause consumer confusion and thus infringe upon that interest.See,e.g., Levi Strauss Co. v. Blue Bell, Inc.,632 F.2d 817, 820-22 (9th Cir. 1980) (Blue Bell I).

[5] Strauss cannot simply rely on the federal registration of certain tabs, most notably of those on pants, to establish a protected interest in a pocket tab on garments generally, because registration constitutes prima facie evidence of a protected interest with respect to the goods specified in the registration only.15 U.S.C. § 1115.2Further, Strauss has not alleged that the tab mark is "inherently distinctive."See1 J. McCarthy,Trademarks and Unfair Competition,§§ 11:1-2 at 433-36 (2d ed. 1984) (hereinafter J. McCarthy). In order to establish the first element of its cause of action, namely a protected interest, Strauss has, therefore, relied upon the doctrine of secondary meaning.

[6] Secondary meaning is another way of expressing the distinctiveness of a trademark.Blue Bell I,632 F.2d at 820. In this circuit, "`[s]econdary meaning has been defined asassociation,nothing more.'"Id.at 820,quotingCarter-Wallace, Inc. v. Proctor Gamble Co.,434 F.2d 794, 802 (9th Cir. 1970). The basic element of secondary meaning is, thus, the mental association by a substantial segment of consumers and potential consumers "between the alleged mark and a single source of the product." 1 J. McCarthy, §§ 15:2 at 659, and 15:11(B) at 686.See Blue Bell I,632 F.2d at 820.

[7] After a bench trial, the district court found that the Strauss tab as applied to the shirt market did not possess secondary meaning and, moreover, that even if the tab as used on shirts was assumed to possess secondary meaning, Blue Bell's use of its tab on shirts was not likely to cause customerPage 1355confusion.3The district court consequently ruled in favor of Blue Bell with respect to both Strauss's federal trademark and state law claims. We affirm the district court as to Strauss's federal trademark and state unfair competition claims, but we remand for further consideration of Strauss's state trademark infringement and dilution claims.
II
[8] The parties agree that ade novostandard of review is appropriate for the district court's rulings on matters of law. They also agree that the question of secondary meaning is one of fact which is reviewed under the "clearly erroneous" standard.Blue Bell I,632 F.2d at 821. They differ, however, as to what standard is appropriate for our review of the trial court's decision that there was no likelihood of confusion. Strauss urges ade novoreview, while Blue Bell argues for the clearly erroneous standard. We hold that henceforth the clearly erroneous standard should be applied in reviewing a trial court's determination concerning likelihood of confusion.4

[9] InUnited States v. McConney,728 F.2d 1195(9th Cir.) (en banc),cert. denied,___ U.S. ___, 105 S.Ct. 101, 83 L.Ed.2d 46 (1984), this court stated that where a mixed question of law and fact is predominantly one of fact, we review the trial court's determination under the clearly erroneous standard. 728 F.2d at 1203-04. The issue of likelihood of confusion is a mixed question which appears to be predominantly factual in nature.

[10] Likelihood of confusion is the type of mixed question which fits within the categories suggested inMcConneyas suited to clearly erroneous review — cases not implicating constitutional rights and those "in which the applicable legal standard provides for a strictly factual test, such as state of mind."Id.at 1203.De novoreview of this issue would demand a significant diversion of appellate court resources to a task which more properly belongs to the district court judge.See id.at 1201 n. 7.See also Miss Universe, Inc. v. Flesher,605 F.2d 1130, 1133 (9th Cir. 1979).Page 1356Moreover, the limited precedential value of likelihood of confusion decisions, each of which stands upon its own facts, reduces the need forde novoreview.McConney,728 F.2d at 1201.See Matter of McLinn,739 F.2d 1395, 1401 (9th Cir. 1984) (en banc).

[11] Whether confusion is likely is a factual determination woven into the law. We routinely treat the issue as one of fact in a variety of procedural contexts.5For the sake of accuracy, uniformity, and consistency with the predominant view in other circuits,6we will hereafter review findings of likelihood of confusion under the clearly erroneous standard.
III
[12] InBlue Bell I,an earlier lawsuit brought by Strauss over Blue Bell's use of a tab on the right rear pocket of itspants,this court determined that Strauss's pocket tab had acquired secondary meaning in the pants market.See632 F.2d at 821. Under the doctrine of collateral estoppel, the Strauss pant pocket tab continues to possess secondary meaning.See, e.g.,Parklane Hosiery Co. v. Shore,439 U.S. 322, 326 n. 5, 99 S.Ct. 645, 649 n. 5, 58 L.Ed.2d 552 (1979). Indeed, the district court explicitly recognized that the pant pocket tab possessed strong secondary meaning.

[13] Strauss argues, however, thatBlue Bell Iestablished that Strauss has (through secondary meaning) a trademark right in a pocket tab on all garments. We cannot agree. Secondary meaning in the pant tab does not necessarily inhere in the shirt tab since the pant tab was registered as a location specific mark.See15 U.S.C. § 1057(b);In re Levi Strauss Co.,165 U.S.P.Q. 348, 350 (TTAB 1970). More important, we do not regard theBlue BellIlitigation as an appropriate basis for collateral estoppel in any area other than the pants market.

[14] In the first place, it is clear that this court inBlue BellIhad no intention of deciding the questions of secondary meaning and likelihood of confusion in any area other than the pants market.

[15] Our ultimate conclusion was:
Strauss has established that a substantial number of prospective buyers associate its pocket tab trademark with only one seller ofpants,and that Wrangler's use of a projecting label with its ends captured in an edge of rear patch pocketPage 1357of itspantsis likely to cause confusion, to cause mistake, or to deceive.7


[16] 632 F.2d at 822 (emphasis added).

[17] Footnote 7 ofBlue Bell Imakes the point clear beyond dispute: "The parties have argued toward general definitions of Strauss's trademark rights under various hypothetical circumstances. Such definitions must await presentation of an actual case or controversy involving established facts."Id.

[18] Under the doctrine of collateral estoppel, judgment in a prior suit between parties precludes retaliation by the parties of issues actually litigated and necessary to the outcome of the first action.Parklane,439 U.S. at 326 n. 5, 99 S.Ct. at 649 n. 5;Clark v. Watchie,513 F.2d 994, 998 (9th Cir.),cert.denied,423 U.S. 841, 96 S.Ct. 72, 46 L.Ed.2d 60 (1975).See1BMoore's Federal Practice¶ 0.441[2], at 722 (1984). Similarity between issues does not suffice; collateral estoppel is applied only when the issues are identical.Parklane,439 U.S. at 326, 99 S.Ct. at 649;Clark v. Watchie,513 F.2d at 998. If different facts are in issue in a second case from those that were litigated in the first case, then the parties are not collaterally estopped from litigation in the second case. If the litigated issues are the same — the same facts at issue — estoppel will apply and an offer of different proof in a later case will not provide escape.

[19] Here, more than the proof is different; the facts are different. We deal with different products (jeans v. shirts) and different markets; and the assumptions, perceptions and recognitions with which customers approach a purchase are different.See Litton Industries v. Litronix, Inc.,577 F.2d 709, 711 (C.C.P.A. 1978) (admission that the previous proceedings involved an application by the same party to register a mark "fordifferentgoods is fatal to the board's reliance on collateral estoppel.").

[20] We cannot say, therefore, thatBlue Bell Iestablished secondary meaning in the Strauss tab as applied to all garments, let alone as applied to shirts.

[21] In the alternative, Strauss argues that even if collateral estoppel is inapplicable, "the evidence offered at trial established as a matter of law that the Levi Strauss Co. pocket tab as used onshirtshad acquired secondary meaning sufficient to entitle Levi Strauss Co. to exclusive usage" (emphasis supplied).

[22] Strauss's argument is two-fold. First, Strauss claims that the district court erred as a matter of law by not considering the secondary meaning in the pant tab as established by collateral estoppel fromBlue Bell I.It insists that this proof was necessarily relevant to a determination of secondary meaning in the shirt tab.

[23] The strength of the tab as a trademark for pants is not irrelevant to the issue of secondary meaning in the shirt market where evidence exists of public awareness and transference of its trademark function to shirts.See Levi Strauss Co. v.Genesco,742 F.2d 1401, 1405 (Fed.Cir. 1984). Strauss did present such evidence.

[24] The district court did not, however, ignore the strong secondary meaning of the pant tab. The court noted: "The strong secondary meaning of the pants' pocket TAB, and the potential for customer confusion arising out of a competing manufacturer's use of a pocket tab device on its pants, has recently been confirmed by the Ninth Circuit Court of Appeals [Blue Bell I]."

[25] The court then gave a very good reason why the strength of the mark in the context of the pants market should not control in the context of the shirt market. It stated, "[t]here is ample and sufficient evidence in the trial to indicate that consumers treat pants and shirts differently. The court finds that consumer perceptions of shirts and pants are different." That statement is more than sufficient to establish that in the judgment of the district court secondary meaning in the pants market does not carry over into the shirt market.

[26] The second prong of Strauss's argument that its shirt tab had acquired secondary meaning is an attack on the validity of thePage 1358affirmative evidence of no secondary meaning relied upon by the district court. As a panel of this court has recently explained:
Factors considered in determining whether a secondary meaning has been achieved include: (1) whether actual purchase[r]s of the product bearing the claimed trademark associate the trademark with the producer, (2) the degree and manner of advertising under the claimed trademark, (3) the length and manner of use of the claimed trademark and, (4) whether use of the claimed trademark has been exclusive.See1 Gilson,Trademark Protection Practice,§ 209[1].


[27]Transgo, Inc. v. AJAC Transmission Parts Corp.,768 F.2d 1001, 1015 (9th Cir. 1985).Accord Zatarains, Inc. v. Oak GroveSmokehouse, Inc.,698 F.2d 786, 795 (5th Cir. 1983). An expert survey of purchasers can provide the most persuasive evidence on secondary meaning. 1 J. McCarthy, § 15:13(D) at 690.SeeZatarains,698 F.2d at 795.

[28] The district court's finding of no secondary meaning in the tab as applied to the shirt market was based primarily upon careful, expert surveys of purchasers, including Strauss's own survey. The survey which the district court believed supported a finding of no secondary meaning was conducted for Strauss and was probative evidence that a substantial segment of the purchasing public did not associate the tab as used on shirts with a single source, i.e., Strauss. The court also recognized the relevance of such circumstantial factors "as the length of time the mark has been used, the extent of advertising, and the volume of sales" and "whether Levi Strauss was the exclusive user of such a projecting label on patch pockets of shirts during that period." Strauss was required to prove that the tab as used on shirts had acquired secondary meaning by 1976, when Blue Bell began using a protruding label on shirts.See HMH Publishing Co. v. Brincat,504 F.2d 713, 715 (9th Cir. 1974). The court found, though, that Strauss had only begun using the tab on shirts in 1969 and that it introduced no evidence of sales of shirts with the tab until 1973. Strauss's evidence on the issue of the tab's first use on shirts is mainly uncorroborated testimony which the district court was entitled to discredit. The court also found that "there is little evidence of Levi's advertising the shirt tab" during the 1969-76 period and that "other companies utilized a shirt pocket tab (even though Levi Strauss, through threat of legal action, was able to have them cease the use of a tab)." Evidence of third party usage did exist and is relevant to disprove the existence of secondary meaning.7See Carter-Wallace,434 F.2d at 802-03. Finally, the district court might well have concluded that Strauss's advertising did not primarily promote the shirt tab as against the shirt as a whole.

[29] Our task is not to determine whether a finding might have been made alternative to that of the district court; it is to determine whether the finding of no secondary meaning was clearly erroneous. Mindful of the evidence in the record supporting the court's finding, we conclude that it was not. InInwoodLaboratories v. Ives Laboratories,456 U.S. 844, 102 S.Ct. 2182, 72 L.Ed.2d 606 (1982), the Supreme Court stated:
By rejecting the District Court's findings simply because it would have given more weight to evidence of mislabeling than did the trial court, the Court of Appeals clearly erred. Determining the weight and credibility of the evidence is the special province of the trier of fact. Because the trial court's findings concerning the significance of the instances of mislabeling were not clearly erroneous, they should not have been disturbed. . . . An appellate court cannot substitute its interpretation of the evidence for that of the trial court simply because the reviewing court "might give the facts anotherPage 1359construction, resolve the ambiguities differently, and find a more sinister cast to actions which the District Court apparently deemed innocent."


[30]Id.at 856-58, 102 S.Ct. at 2189-90,quoting United States v.National Ass'n. of Real Estate Boards,339 U.S. 485, 495, 70 S.Ct. 711, 717, 94 L.Ed. 1007 (1950). We similarly decline to reweigh the evidence in this case.

[31] In summary, Strauss pleaded this case not as an infringement of its tab as applied to the pants market or as applied to the shirt market, but as an infringement of its alleged trademark rights in a pocket tab on garments generally. The district court correctly recognized that secondary meaning inhered in the tab as applied to the pants market, but it did not err in finding no secondary meaning in the tab as applied to the shirt market. Because the tab is a location specific mark, the court could not properly have made findings concerning trademark rights in a pocket tab on garments generally.
IV
[32] The finding of no secondary meaning in the tab as applied to the shirt market would normally foreclose any possibility of likelihood of confusion.See Sleeper Lounge Co. v. BellManufacturing Co.,253 F.2d 720, 723 (9th Cir. 1958). In order to establish customer confusion Strauss must establish that use of the Blue Bell mark on shirts is likely to cause a reasonably knowledgeable and prudent purchaser to believe that Strauss was the manufacturer of Blue Bell shirts.See Toho Co. v. Sears,Roebuck Co.,645 F.2d 788, 790 (9th Cir. 1981). A buyer cannot, however, be "confused unless he is looking for a label he recognizes and picks up another in his confusion. Ergo, a buyer who does not recognize plaintiff's `mark' and does not distinguish it from any other, cannot be confused." 1 J. McCarthy, § 15:3 at p. 668.

[33] Strauss argues that this case is unusual in that Strauss has established secondary meaning in the tab as applied to the pants market and that likelihood of confusion may, therefore, also be established between the Strauss pant tab and the Blue Bell shirt tab. Theindependentfinding that Strauss'sshirttab does not possess secondary meaning dooms this argument to failure. Ultimately, even if the tab does possess secondary meaning in the pants market, Strauss must establish that consumers are likely to believe that Blue Bell shirts emanate from Strauss. If, however, consumers do not distinguish Strauss's mark on shirts, then it is axiomatic that they will not attribute Blue Bell shirts to Strauss, even if they distinguish Strauss's mark on pants. To allow Strauss to establish likelihood of confusion in the shirt market on the basis of the secondary meaning of its tab in the pants market would, in short, be tantamount to allowing a second opportunity to prove that consumers distinguish Strauss's mark on shirts. We have held that they do not.

[34] Strauss's appeal to the "related goods" doctrine,see AMF,Inc. v. Sleekcraft Boats,599 F.2d 341, 348 (9th Cir. 1979), is to no avail. The related goods analysis is designed to protect a mark from infringement by a similar mark on noncompetitive goods; a buyer may still be likely to assume a common source or sponsorship. 2 J. McCarthy, § 24:6 at 182. In other words, the related goods test serves largely to define the potential scope of secondary meaning. If the doctrine serves any purpose other than to define the potential reach of secondary meaning, it is only as a manifestation of the ultimate test of likelihood of confusion.See id.at 183.8Here, however, even if pants and shirts are relatedPage 1360goods, an independent analysis has established that secondary meaning in the Strauss tab does not extend to the shirt market, and there is consequently no need to undertake a separate "related goods" analysis.
V
[35] The district court found, in the alternative, that even if Strauss's pocket tab had acquired secondary meaning, and thus a protected trademark right, as applied to the shirt market, Strauss could not prevail in this action because it had failed to demonstrate infringement of that right through likelihood of confusion.

[36] As an initial matter, we note that the likelihood of confusion issue is only reached in this case upon the assumption that the Strauss tab as applied to the shirt market possesses secondary meaning. We reiterate our conclusion,see supranote 8, that the related goods test incorporates the same factors as are applied in cases involving competitive goods, with the addition of such factors as the proximity of the goods and the likelihood of expansion of product lines. Proceeding upon the assumption that a directly competing good manufactured by Strauss possesses secondary meaning renders factors such as "likelihood of expansion of product lines" superfluous, and we, therefore, see no need to employ any supplementary related goods analysis.9

[37] Strauss argues that the district court ignored the multifactor test which has been set forth by this court. This simply is not so. The court stated:
Factors that are relevant in determining whether a likelihood of confusion exists are strength or weakness of the marks; similarity in appearance, sound, and meaning; class of goods in question; marketing channels used; evidence of actual confusion; type of goods and degree of care exercised by purchaser; and intent of defendant [citations omitted].


[38] No allegation has been made that the district court wrongly prohibited Strauss from introducing evidence on any of these factors.

[39] It is true that certain aspects of the multifactor test describe the circumstances to which a trier of fact would refer in making an educatedguessas to what was going on in the minds of consumers in the absence of direct proof, such as survey evidence and testimony, as to how consumers were responding to the marks. Survey evidence and testimony may, however, outweigh whatever circumstantial evidence has been introduced.Cf.Anti-Monopoly, Inc. v. General Mills Fun Group, Inc.,684 F.2d 1316, 1323 (9th Cir. 1982),cert. denied,459 U.S. 1227, 103 S.Ct. 1234, 75 L.Ed.2d 468 (1983) (consumer surveys are ample and legitimate evidence in trademark cases); 2 J. McCarthy, §§ 32:46-55 (discussion of the use of survey evidence in trademark cases).

[40] We recognize that survey evidence and retailer testimony are primarily relevant to the existence of actual confusion, which is but one facet of the multifactor test.10It was, however, the prerogative of the district court to evaluate and weigh the evidence introduced by Strauss and Blue Bell, and to find that Blue Bell's direct evidence outweighed Strauss's circumstantial evidence. Our job as an appellate court is not to reweigh the evidence.See Inwood Laboratories,456 U.S. at 856-58, 102 S.Ct. at 2189-90.

[41] Retailers called by Blue Bell testified that, based upon their experience, they didPage 1361not believe that Blue Bell's shirt tab would confuse customers. Further, both Strauss and Blue Bell employed independent survey organizations to conduct surveys of purchasers of children's shirts. The district court discussed those surveys in detail, including the manner in which survey organizations selected the random samples, the questions that the survey interviewers asked, and the results of those questions. The possibility that the consumer views expressed were easily influenced, uncertain or uninformed is, therefore, quite low. Further, the possibility that the surveys were artificial or unreflective of the views of persons who simply notice Blue Bell shirts during casual street encounters was diminished by the use of shirt tabs by both parties over several years and their substantial presence in the shirt market. The court, in making credibility determinations and weighing the evidence, found Blue Bell's survey evidence more credible than that of Strauss. The court concluded, however, that both parties' survey evidence indicated that there was no reasonable likelihood of customer confusion.

[42] We conclude, therefore, that the ultimate finding of the district court of no likelihood of confusion was not clearly erroneous.11
VI
[43] Counts III and IV of Strauss's complaint alleged infringement of state trademark rights, dilution of its trademarks under state law, and unfair competition under section 3369 of the California Civil Code.
A
[44] We have recently suggested that the standard of review for infringement claims based upon state law is more deferential than that used for Lanham Act decisions.Monte Carlo Shirt, Inc. v.Daewoo International (America) Corp.,707 F.2d 1054, 1056-57 (9th Cir. 1983). The state law-federal law distinction in review was eliminated, however, inMatter of McLinn,739 F.2d at 1397, where our court held en banc that in both cases review should bede novo.WhileMcLinndid not discuss review of issues which mix fact withstatelaw, andMcConneyapparently dealt with issues which mix fact withfederallaw, 728 F.2d at 1199-1204,McLinnrelied extensively upon theMcConneyopinion to reach the holding that "appellate review of conclusions of state law should be under the same . . . standard as conclusions of federal law."McLinn,739 F.2d at 1403. Thus, we conclude that the standard of review is the same for both federal infringement claims and those pendent state claims presented here. We will review questions of state lawde novoand the factual conclusions of likelihood of confusion under the clearly erroneous standard.
B
[45] In considering Strauss's state trademark infringement claim, the district court, after finding that Strauss's shirt tab trademark was validly registered, erroneously failed to give Strauss the benefit of a presumption that it thereby met its burden of proof in establishing the validity of this trademark under state law. State registration of a trademark constitutes "prima facie evidence of the ownership of such mark . . . in the State of California." Cal.Bus. Prof.Code § 14241 (West 1984).See, e.g., North Carolina Dairy Foundation, Inc. v.Foremost-McKesson, Inc.,92 Cal.App.3d 98, 106 n. 5, 154 Cal.Rptr. 794, 798 n. 5 (1979).

[46] Moreover, the district court erred when it rejected Strauss's state law trademark infringement claim largely on the basis of survey evidence which was found reflective of consumer attitudes throughout the continental United States. Certain state law trademark infringement claims may be joined with federal claims for trial, and a plaintiff can prevail on either, neither, or both.Golden Door, Inc. v. Odisho,646 F.2d 347, 352 (9th Cir. 1980);International Order of Job's Daughters v.Page 1362Lindeburg Co.,633 F.2d 912, 915-16 (9th Cir. 1980),cert. denied,452 U.S. 941, 101 S.Ct. 3086, 69 L.Ed.2d 956 (1981). If confusion inCalifornia(the location of Strauss's headquarters) can be shown, remedies under California law may be available.
C
[47] In considering Strauss's dilution claim, the district court erroneously concluded that absent a showing of likelihood of confusion, Strauss could not establish a right to relief. The dilution statute expressly states that the possibility of dilution of a trademark "shall be a ground for injunctive relief notwithstanding . . . the absence of confusion as to the source of goods or services." Cal.Bus. Prof.Code § 14330 (West 1984).See Monte Carlo Shirt,707 F.2d at 1058 n. 4;Toho,645 F.2d at 793;Walt Disney Productions v. Air Pirates,581 F.2d 751, 760 n. 19 (9th Cir. 1978),cert. denied,439 U.S. 1132, 99 S.Ct. 1054, 59 L.Ed.2d 94 (1979). Thus, the district court erred as a matter of law in dismissing the dilution claim upon this basis alone.

[48] The district court did not err in dismissing Strauss's state unfair competition claim, since both secondary meaning and a likelihood of public confusion are required in order to prevail.See, e.g., Allied Artists Pictures Corp. v. Friedman,68 Cal.App.3d 127, 134-36, 137 Cal.Rptr. 94, 98-99 (1977); 7 B. Witkin,Summary of California Law, Equity§§ 74, 75 (8th ed. 1974).
E
[49] We, therefore, vacate the portion of the judgment dismissing Strauss's dilution and state trademark infringement claims and remand those portions of the action to the district court.

[50] Because we affirm the dismissal of the federal portions of Strauss's action, however, we leave to the discretion of the district court the question of whether exercise of pendent jurisdiction over this purely state claim is appropriate or whether it should be dismissed without prejudice.United MineWorkers v. Gibbs,383 U.S. 715, 727-29, 86 S.Ct. 1130, 1139-40, 16 L.Ed.2d 218 (1966).See Wham-O-Mfg. Co. v. ParadiseManufacturing Co.,327 F.2d 748, 753-54 (9th Cir. 1964). We note that diversity jurisdiction does not exist between the parties because both Strauss and Blue Bell are incorporated in Delaware,see28 U.S.C. § 1332(c), and the sole basis of the district court's jurisdiction over the dilution claim remains pendent jurisdiction under28 U.S.C. § 1338(b).

[51] JUDGMENT AFFIRMED IN PART, VACATED AND REMANDED IN PART.
[52] NELSON, Circuit Judge, with whom GOODWIN and BOOCHEVER, Circuit Judges, join, concurring in part and dissenting in part:
[53] I concur in Part II and in sections A, B, and C of Part VI, but respectfully dissent from the remainder of the opinion.

[54] InLevi Strauss Co. v. Blue Bell, Inc.,632 F.2d 817(9th Cir. 1980) ("Blue Bell I"), we protected Strauss' pant pocket tab against Blue Bell's infringement in the casual pants market. Here, Strauss seeks relief when Blue Bell places the identical tab on casual shirts. Casual pants and casual shirts are "related goods" — they are complementary items,1sold through the same channels of trade,2used by the same purchasers,3and sold within the same price range.4There could be no clearer case for application of the related goods doctrine. Casual pants and shirts satisfyevery oneof the requirements for protection. The district court erred in not applying the related goods doctrine to pants and shirts.Page 1363

[55] By summarily rejecting the related goods claim, the district court did not even consider the secondary meaning of the pant pocket tab in the shirt market, an issue resolved inBlue BellI.This should be done on remand.

[56] The district court's rejection of the related goods claim resulted, further, in its failure to apply the multi-factor framework set forth by our cases for determining likelihood of consumer confusion. In addition, where the district courtdidpurport to apply the multi-factor test — in Strauss' claim of infringement upon itsshirttab — it did so incorrectly. Accordingly, the case should be remanded for proper application of the multi-factor framework.
I.
[57]Related Goods Doctrine
[58] Strauss seeks two forms of relief in this lawsuit. First, it seeks protection of its shirt pocket tab in the shirt market. Blue Bell shirts and Strauss shirts are directly competitive goods; the related goods doctrine is inapplicable to this contention. However, Strauss also seeks protection of itspantpocket tab in the shirt market. Pants and shirts are not competitive goods, so the related goods doctrine should be used to determine if relief is warranted.

[59] Related goods are those goods which, though not identical, are related in the minds of consumers.In Fleischmann DistillingCorp. v. Maier Brewing Co.,314 F.2d 149, 152-53 (9th Cir.),cert. denied,374 U.S. 830, 83 S.Ct. 1870, 10 L.Ed.2d 1053 (1963), this circuit determined that whiskey and beer were related goods, and reversed a district court judgment that had denied trademark protection solely on the basis that the two products were "different."Id.at 152. InYale Electric Corp.v. Robertson,26 F.2d 972(2d Cir. 1928), the Second Circuit (per Judge Learned Hand) held that a lock manufacturer could be protected against trademark infringement by a flashlight manufacturer, despite the differences in the underlying goods. Yet in this case, the district court truncated consideration of Strauss' claim for protection of its pant tab by saying only that "pants and shirts are different." It refused to consider Strauss' proof that, in many ways, pants and shirts are "related" in the eyes of consumers.

[60] The casual pants and casual shirts at issue here are certainly related goods. They are complementary items, brought to market through the same channels of trade, used by the same purchasers, and sold within the same price range.See Sleekcraft,599 F.2d at 350. Furthermore, Trademark courts routinely consider all items of wearing apparel to be related.See, e.g., In re DuofoldInc.,184 USPQ 638 (TT A Bd. 1974);In re Sox Unlimited,Inc.,169 USPQ 682 (TT A Bd. 1971);In re Cosmetically Yours,171 USPQ 563 (TT A Bd. 1971). The district court's denial of related goods protection based upon its articulated rationale that "pants and shirts are different" should be reversed.
II.
[61]Secondary Meaning

[62] A.Strauss's Pants versus Blue Bell's Shirts.

[63] When the district court summarily rejected the related goods claims, it failed to consider the secondary meaning of the pant pocket tab. It should do so on remand when applying the related goods test.

[64]Blue Bell Iclearly established the secondary meaning of the pant tab. In that case, we affirmed a finding that the pant "pocket tab trademark has acquired a secondary meaning in the marketplace and is distinctive of [Strauss'] garments in commerce." 632 F.2d at 821. We also held: "The evidence of secondary meaning is strong and the Strauss mark is entitled toa broad scope of protection." Id.(emphasis added). Since the district court erroneously thought this suit concerned only shirts, it ruled that collateral estoppel did not apply becauseBlue Bell Iconcerned pants. However, under the related goods doctrine, the issue of secondary meaning of the pant tab is a part of this action. It wasPage 1364litigated inBlue Bell Iby the two parties to this litigation. Under ordinary principles of collateral estoppel, parties cannot relitigate factual issues that were conclusively determined in an earlier lawsuit.See, e.g., Parklance HosieryCo. v. Shore,439 U.S. 322, 326 n. 5, 99 S.Ct. 645, 649 n. 5, 58 L.Ed.2d 552 (1979). Neither party suggests that the pant pocket tab has been altered sinceBlue Bell Ior that consumers no longer associate the pant tab with Strauss. Therefore, under the doctrine of collateral estoppel, the Strauss pant pocket tab has secondary meaning which should have been considered by the district court in considering the related goods claim of the infringement of Strauss' pant tab trademark.

[65] B.Strauss' Shirts versus Blue Bell's Shirts.

[66] I agree with the majority that Blue Bell I doesnothave collateral estoppel effect upon a finding of secondary meaning of theshirttab. This issue has never before been litigated by the parties. Secondary meaning in the pant tab does not necessarily inhere in the shirt tab, since the pant tab was registered as a location-specific trademark.See In re LeviStrauss,165 USPQ 348, 350 (TT A Bd. 1970).
III.
[67]Likelihood of Confusion
[68] Our cases have defined a multi-factor framework to determine the likelihood of consumer confusion.See New West Corp. v. NYMCo. of Cal., Inc.,595 F.2d 1194, 1201 (9th Cir. 1979);J.B.Williams Co. v. Le Conte Cosmetics, Inc.,523 F.2d 187, 191 (9th Cir. 1975),cert. denied,424 U.S. 913, 96 S.Ct. 1110, 47 L.Ed.2d 317 (1976);K-S-H Plastics, Inc. v. Carolite, Inc.,408 F.2d 54, 57 (9th Cir.),cert. denied,396 U.S. 825, 90 S.Ct. 69, 24 L.Ed.2d 76 (1969).AMF Inc. v. Sleekcraft Boats,599 F.2d 341(9th Cir. 1979) sets forth eight factors to be considered:
1. strength of the mark;
2. proximity of the goods;
3. similarity of the marks;
4. evidence of actual confusion;
5. marketing channels used;
6. type of good and degree of care likely to be exercised by the purchaser;
7. defendant's intent in selecting the mark; and
8. likelihood of expansion of the product lines;


[69]Id.at 348-49.

[70] I agree with the majority that the clearly erroneous standard of review should be applied to a trial court's determination of likelihood of confusion — but only if that determination is arrived at through the proper application of the multi-factor test. The district court's failure to apply the multi-factor test to the pants versus shirts claim, and its failure to apply all of that test's factors to the shirts versus shirts claim are errors of law. They must be reviewedde novo. See Bose Corp. v.Consumers Union of United States, Inc.,466 U.S. 485, 104 S.Ct. 1949, 1959-60 n. 17, 80 L.Ed.2d 502 (1984) ("Rule 52(a) does not inhibit an appellate court's power to correct errors of law, including those that may infect a so-called mixed finding of law and fact, or a finding that is predicated on a misunderstanding of the governing rule of law.").Pizzeria Uno Corp. v. Temple,747 F.2d 1522, 1526 (4th Cir. 1984) ("Nor will the clearly erroneous rule protect findings which have been made on the basis of the application of incorrect legal standards or made in disregard of applicable legal standards. . . .");Kentucky FriedChicken Corp. v. Diversified Packaging Corp.,549 F.2d 368, 384 (5th Cir. 1977) (if test applied is incorrect as a matter of law, "findings lose the shield of the `clearly erroneous' standard"). When, as here, the appropriate legal standard is not applied at all or applied incorrectly, remand is necessary for factual determinations to be made on the basis of the correct legal standard.Pullman-Standard v. Swint,456 U.S. 273, 292, 102 S.Ct. 1781, 1792, 72 L.Ed.2d 66 (1982);United States v. SingerManufacturing Co.,374 U.S. 174, 194 n. 9, 83 S.Ct. 1773, 1784 n. 9, 10 L.Ed.2d 823 (1963).See Bose Corp.,104 S.Ct. at 1959-60 n. 17.

[71] With respect to the related goods claim, the district court should be directed to applyPage 1365the multi-factor test. With respect to the shirts versus shirt claim, the district court should be directed to apply that test properly. For while the district court did attempt to apply the multi-factor test to the shirts versus shirts claim, it failed to consider all the relevant factors. The majority opinion attempts to legitimize the district court's focus on only one factor — the survey evidence — by characterizing that factor as "direct evidence" and stigmatizing the others as "circumstantial." However, the district court's failure to make sufficiently detailed findings on some of the factors and its misconstruction of others cannot be overlooked.

[72] For instance, when considering the strength of the mark with respect to the Strauss shirt tab, the district court erred as a matter of law in excluding the pant tab's secondary meaning from its determination of the shirt tab's strength of the mark; consequently, its conclusion that the shirt tab is a weak mark cannot be sustained.

[73] On the question of marketing channels, the district court found that the fact that Strauss and Blue Bell shirts were sold in the same stores did not render confusion as "more like[ly] to occur." It miscited a case for this proposition,Interstate Brands Corp.v. Celestial Seasonings,576 F.2d 926(C.C.P.A. 1978), and the rule is to the contrary.

[74] On the question of similarity of the marks, the district court found that the similarity of the marks was reduced by Blue Bell's distinctive point of sale packaging and advertising materials. The proper inquiry, however, considers the similarity of the marks as encountered by consumers throughout the marketplace, and not merely at the point of sale.See Lindy Pen Co. v. Bic PenCorp.,725 F.2d 1240, 1245 (9th Cir. 1984);Blue Bell I,632 F.2d at 822.

[75] Finally, among the factors not even considered by the district court were proximity of goods, type of goods, and degree of care exercised by purchasers. Nor did it consider the degree of competition between Strauss' shirts and Blue Bell's shirts, although highly competitive goods receive greater trademark protection.Sleekcraft,599 F.2d at 354;see also New West,595 F.2d at 1202;Paul Sachs Original,325 F.2d at 215.
[76] CONCLUSION
[77] While I concur in Part II and in sections A, B, and C of Part VI of the majority opinion, I would reverse and remand this case to the district court for application of the related goods doctrine, a consideration of the secondary meaning of the pant tab as applied to the related goods doctrine, and for application of this Circuit's multi-factor test to both the infringement of Strauss'panttab by Blue Bell'sshirttab and the infringement of Strauss'shirttab by Blue Bell'sshirttab.

[78] CONCURRING IN PART, DISSENTING IN PART.
  1. 15 U.S.C. § 1114(1)(a) creates civil liability in anyone who makes use in commerce of "any reproduction, counterfeit, copy, or colorable imitation of a registered mark" in connection with the sale of goods where such use "is likely to cause confusion, or to cause mistake, or to deceive."

    Section 1125(a) creates civil liability in one who markets goods with a false designation of origin including "words or other symbols tending falsely to describe or represent the same." ↩
  2. 15 U.S.C. § 1114, which prohibits trademark infringement, applies only to marks with federal registration, and, therefore, pertains only to any infringement which can be proved of registered marks. Section 1125(a), which prohibits false designation of origin, is not, however, limited to registered marks. ↩
  3. Most of the evidence at trial pertained to the market for children's shirts. Even so, the district court recognized that Strauss and Blue Bell compete in the markets for men's, women's, and children's shirts, and our holding here covers all shirts manufactured by Blue Bell and Strauss which bear projecting tabs on patch pockets. ↩
  4. The parties focus upon their disagreement concerning whether the trial court's decision was based upon undisputed facts. Until today, the degree of deference accorded in this circuit to trial court likelihood of confusion determinations has hinged upon the nature of the evidence below. We have reviewed such determinationsde novowhen based upon undisputed facts, but have applied a different, two-level test where disputed facts have been involved, applying the clearly erroneous standard to the underlying "foundational facts" and givingde novoreview to the "legal conclusion" on likelihood of confusion.AMF, Inc.v. Sleekcraft Boats,599 F.2d 341, 346-47 (9th Cir. 1979).SeeAlpha Industries, Inc. v. Alpha Steel Tube Shapes, Inc.,616 F.2d 440, 443-44 (9th Cir. 1980);J.B. Williams Co. v. Le ConteCosmetics, Inc.,523 F.2d 187, 191 (9th Cir. 1975),cert.denied,424 U.S. 913, 96 S.Ct. 1110, 47 L.Ed.2d 317 (1976). The distinction between these alternative tests has, however, often been omitted or obscured.See Lindy Pen Co. v. Bic Pen Corp.,725 F.2d 1240, 1243-44 (9th Cir. 1984) (omitting disputed facts/undisputed facts distinction),cert. denied,___ U.S. ___, 105 S.Ct. 955, 83 L.Ed.2d 962 (1985);Golden Door, Inc. v.Odisho,646 F.2d 347, 350 (9th Cir. 1980);Blue Bell I,632 F.2d at 822 n. 6. At least one commentator concluded that the distinction had been abolished and that the two-level test had become universally applicable. J. Gilson,Trademark Protectionand Practice,§ 8.15 at 8-194 (1984) (hereinafter Gilson).

    In now dispensing with our previous distinctions based upon the disputed or undisputed nature of the facts, we are in accord with analogous principles from non-trademark fields.See Commissionerof Internal Revenue v. Duberstein,363 U.S. 278, 291, 80 S.Ct. 1190, 1200, 4 L.Ed.2d 1218 (1959) (Rule 52(a) applies to factual inferences from undisputed facts);United States v. Chesher,678 F.2d 1353, 1358 n. 3 (9th Cir. 1982) (clearly erroneous standard applies to trial judge's decision based on stipulated facts);Lundgren v. Freeman,307 F.2d 104, 113-15 (9th Cir. 1962) (Rule 52(a) applies to findings based upon documentary evidence as well as to those involving witness credibility); Note of Advisory Committee on Rules, Fed.R.Civ.P. 52 (deference mandated by Rule 52(a) is not limited to the trial judge's resolution of disputed facts). ↩
  5. See2 J. McCarthy, § 32:37 at 745. For instance, trial courts disfavor deciding trademark cases in summary judgments because the ultimate issue is so inherently factual.See, e.g.,United States Jaycees v. San Francisco Junior Chamber ofCommerce,354 F. Supp. 61, 68-69 (N.D.Cal. 1972),aff'd,513 F.2d 1226(9th Cir. 1975) (per curiam). Additionally, the question of likelihood of confusion is routinely submitted for jury determination as a question of fact.See Stuart v.Collins,489 F. Supp. 827, 830 (S.D. N.Y. 1980);Five Platters,Inc. v. Purdie,419 F. Supp. 372, 381-82 (D.Md. 1976). ↩
  6. A review of trademark cases in other circuits demonstrates that the clearly erroneous standard predominates for review of a district court's determination on likelihood of confusion.Seegenerally Gilson,§ 8:14 at 8-189; 2 J. McCarthy, § 23:22 at 111 n. 15, 113 n. 20; Comment,Appellate Review of Lanham ActViolations: Is Likelihood of Confusion a Question of Law orFact?,38 Sw.L.J. 743, 752 n. 77, 752-762 (1984). In dissenting from the denial of certiorari for a case in which the Sixth Circuit adopted the two-level test, Justice White partially documented the disparity in the standards employed by the various circuits.Elby's Big Boy of Steubenville, Inc. v. Frisch'sRestaurants,459 U.S. 916, 103 S.Ct. 231, 74 L.Ed.2d 182 (1982) (White, J., dissenting). Justice White noted that the First, Fifth, and Eighth Circuits follow the clearly erroneous standard.Id.(citingKeebler Co. v. Rovira Biscuit Corp.,624 F.2d 366, 377 (1st Cir. 1980);Sun Banks of Florida, Inc. v. SunFederal Savings Loan Ass'n,651 F.2d 311, 314-15 (5th Cir. 1981);Squirtco v. Seven-Up Co.,628 F.2d 1086, 1091 (8th Cir. 1980)). In addition, the Fourth, Tenth, and Eleventh Circuits appear to follow the clearly erroneous standard.See PizzeriaUno Corp. v. Temple,747 F.2d 1522, 1526 (4th Cir. 1984);Frito-Lay, Inc. v. Morton Foods, Inc.,316 F.2d 298, 300 (10th Cir. 1963);Jellibeans, Inc. v. Skating Clubs of Georgia, Inc.,716 F.2d 833, 839-40 (11th Cir. 1983). The Second Circuit and the Seventh Circuit treat likelihood of confusion as a question of fact, utilizingde novoreview only for comparisons of the similarity of the marks.Playboy Enterprises v. ChuckleberryPublishing, Inc.,687 F.2d 563, 566 (2d Cir. 1982);Henri's FoodProducts Co. v. Kraft, Inc.,717 F.2d 352, 354 (7th Cir. 1983);James Burrough Ltd. v. Sign of the Beefeater, Inc.,540 F.2d 266, 273 (7th Cir. 1976). ↩
  7. The issue in this case is not whether Strauss abandoned a trademark, but whether trademark rights had attached at all. ↩
  8. The related goods test is not a separate test for establishing likelihood of confusion but incorporates the same factors which are applied in cases involving competitive goods with the addition of such factors as the "proximity" of the goods and the likelihood of expansion of the product lines.See, e.g.,Lindy Pen,725 F.2d at 1243;Golden Door,646 F.2d at 349-50;AMF,599 F.2d at 348-49;New West Corp. v. NYM Co.,595 F.2d 1194, 1201 (9th Cir. 1979);K-S-H Plastics, Inc. v. Carolite,Inc.,408 F.2d 54, 57 (9th Cir.),cert. denied,396 U.S. 825, 90 S.Ct. 69, 24 L.Ed.2d 76 (1969);Paul Sachs Originals Co. v.Sachs,325 F.2d 212, 214 (9th Cir. 1963). ↩
  9. We also note that, for the reasons discussedsupra,the issue of likelihood of confusion in the shirt market is no more subject to any collateral estoppel effect from the pants litigation than was the issue of secondary meaning. ↩
  10. The absence of evidence of actual confusion need not give rise to an inference of no likelihood of confusion.GoldenDoor,646 F.2d at 351. Strauss was, however, by no means foreclosed from putting on evidence of actual confusion in proving likelihood of confusion. In fact, Strauss did introduce such evidence. Moreover, Blue Bell was not barred from putting on evidence of no actual confusion merely because Strauss was not required to prove actual confusion. ↩
  11. Our holding is limited to the facts on this record and we express no opinion as to whether some other use of a pocket tab by Blue Bell or another manufacturer might lead to a likelihood of confusion with products manufactured by Strauss. ↩
