When Internet start-up Natural Answers, Inc. began marketing a line of herbal products called Herbscriptions, we assume it hoped to avoid getting embroiled in a nasty court fight, especially one with a global pharmaceutical giant like the Eli Lilly company. But no such luck, for here it is (along with its founder Brian Fein-stein), asking us to reverse a district court order, granted on Lilly’s motion for a preliminary injunction, which stopped Natural Answers from marketing its herbal “mood elevator” HERBROZAC. Although Natural Answers does its best to paint this case as David versus Goliath, and hopes for a result similar to that achieved by David, it doesn’t have much of a slingshot to carry into the battle.
The basis of Lilly’s claim is that the name HERBROZAC comes unfairly close to Lilly’s protected mark for PROZAC®, a prescription drug used to treat clinical depression. PROZAC® has received considerable media attention since its rollout in 1988, appearing twice (March 26, 1990, and February 7, 1994) on the cover of Newsweek. In 1999 Fortune magazine named it one of the top six “health and grooming” products of the 20th Century. 1 PROZAC® has been prescribed over 240 million times for 17 million Americans, generating sales of more than $12 billion.
*460 Natural Answers develops, markets, and sells a line of herbal dietary supplements that it calls Herbscriptions. Herbscrip-tions are positioned as “drug alternatives” and include supplements called Herbe-nolPM, HERBALIUM, HERBASPIRIN, and HERBADRYL. Natural Answers’ Feinstein testified that each name was chosen to call to mind the function of a famous drug from which, its name is derived. 2 Although Natural Answers is careful to characterize its products as alternatives to drugs, as opposed to substitutes for drugs, Feinstein testified that he hopes to persuade consumers not to have “a default reaction to immediately go to their physician ■ and have a prescription for something they may not need.”
Natural Answers markets its Herbscrip-tions line exclusively through its Internet Web site but plans to expand its channels of distribution to include retail outlets like health food and convenience stores. Natural Answers’ Web site contains a column labeled “Think Herbs - not drugs!”, under which it reads “Don’t get your prescriptions filled with drugs ... Get your Herb-scriptions filled with Nature!” The Web site also features a table labeled “Herbs v. Drugs” which contrasts Natural Answers’ products with a generic “Drug Alternative.” In addition, until December 1999, Natural Answers’ Web site contained a source code which included the term “Prozac” as a metatag, 3 and described HERB-ROZAC as “a powerful, and effective all-natural and herbal formula alternative to the prescription drug Prozac.” Internet search engines read source codes, which are not immediately visible to an Internet user, in response to search queries. Natural Answers’ use of'“Prozac” as a metatag was an attempt to guide Internet users searching for information on PROZAC® to Natural Answers’ Web site. This effort apparently was unsuccessful, however, because searchers entering the keyword “Prozac” were swamped with Web sites containing a greater number of references to PROZAC®. Natural Answers removed the term “Prozac” from its source codes in response to this lawsuit.
HERBROZAC is positioned as a “mood elevator.” In order to maintain its status as a “food,” and thus remain beyond the scope of the Food and Drug Administration’s drug approval process, HERBRO-ZAC’s label warns that “[t]his product is not intended to diagnose, treat or cure any disease.” No prescription is necessary to purchase HERBROZAC. The tablets themselves are larger than average, dark brown with black specs, and have a distinctly herbal odor. In contrast, PROZAC® is available only with a doctor’s prescription, which can be filled only by a licensed pharmacist. PROZAC® tablets are green and off-white, and smaller than average.
Before Natural Answers could get HERB-ROZAC off the ground, Lilly sued to enjoin use of that name, claiming infringement under the Lanham Trademark Act, 15 U.S.C. § 1125(a), dilution under the *461 Federal Trademark Dilution Act, 15 U.S.C. § 1125(c), and violation of Indiana’s unfair competition law. Addressing the federal claims only, the district court held that Lilly would likely succeed in proving at trial that the HERBROZAC name is likely to confuse consumers under the Lanham Act. In addition, after holding that Lilly was not required to demonstrate actual dilution in order to obtain relief under the Trademark Dilution Act, the court found that use of the HERBROZAC name created a likelihood of dilution of the PROZAC® mark. Accordingly, the district court enjoined Natural Answers from further use of the HERBROZAC name and ordered that the references to PROZAC® be removed from the source files of Natural Answers’ Web site. At that time, Natural Answers had sold less than $2,000 worth of the supplement. This appeal followed.
The standard for deciding a motion for a preliminary injunction is well-established and need not be restated at length. Suffice it to say that the moving party is required to demonstrate a likelihood of success on the merits, that it has no adequate remedy at law, and that it will suffer irreparable harm if preliminary relief is denied.
Abbott Labs. v. Mead Johnson & Co.,
The district court (Judge David F. Hamilton presiding) painstakingly followed the prescribed formula, although it devoted the bulk of its analysis to Lilly’s likelihood of success on the merits. Because the other factors are easily resolved, we’ll follow the district court’s lead. We review the district court’s decision to grant a preliminary injunction under the abuse of discretion-standard.
Abbott Labs.,
We turn first to the Lanham Act, enacted in 1946. In the Act, Congress explicitly stated it intended to protect registered marks from interference by state legislation, prevent unfair competition, and protect against fraud “by the use of. reproductions, copies, counterfeits, or colorable imitations of registered marks .... ” 15 U.S.C. § 1127. Against this background suggesting a broad legislative purpose, courts have come to a consensus that a Lanham Act plaintiff need only establish that its mark is protectable and that the junior mark is likely to cause confusion among consumers.
Munters Corp. v. Matsid Am., Inc.,
Natural Answers does contend, however, that consumers are unlikely to be confused by the HERBROZAC name. In assessing the likelihood of consumer confusion, we generally consider seven factors: (1) the similarity between the marks in appearance and suggestion, (2) the similarity of the products, (3) the area and manner of concurrent use of the products, (4) the degreé of care likely to be exercised by consumers, (5) the strength of the com
*462
plainant’s mark, (6) any evidence of actual confusion, and (7) the defendant’s intent (or lack thereof) to palm off its product as that of another.
Smith Fiberglass Prods., Inc. v. Ameron, Inc.,
After an exhaustive analysis of each of the relevant factors, Judge Hamilton concluded that use of the HERBROZAC name was likely to confuse consumers. Specifically, he found that the similarity between the two marks and products, the strength of the PROZAC® mark, consumers’ degree of care in choosing between PROZAC® and HERBROZAC, alleged evidence of actual confusion, and Natural Answers’ intent to palm off all created a likelihood of confusion. The conclusion regarding likelihood of confusion is a finding of fact which will not be reversed unless it is clearly erroneous.
Smith Fiberglass Prods.,
The similarity between the names PROZAC® and HERBROZAC is obvious: HERBROZAC contains five of the six letters in PROZAC®, and the “B” in HERB-ROZAC sounds similar to the “P” in PROZAC®. Natural Answers argues that the two marks are dissimilar because HERB-ROZAC may be pronounced with an emphasis on the first syllable (HERBrozac), thus rendering the “B” and “P” sounds less similar than when the second syllable of HERBROZAC is emphasized (herBRO-zac). Even under Natural Answers’ preferred pronunciation (which seems contrary to the natural pronunciation of a combination of the root words “herb” and “Prozac”), however, the two words are strikingly similar.
Natural Answers next argues that the HERBROZAC name merely “calls to mind” PROZAC®, while at the same time distinguishing itself. The mere fact that one mark brings another mark to mind is not sufficient to establish a likelihood of confusion as to the source of the product.
Application of Ferrero,
As the district court found, however, “HERBROZAC does much more than merely ‘call to mind’ the PROZAC® mark.” Unlike the mark at issue in
Ferrero,
PROZAC® is a fanciful word that has no meaning independent of Lilly’s mark. Such marks are entitled to the highest protection.
See Seven-Up Co. v. Tropicana Prods., Inc.,
Another factor is whether HERBRO-ZAC and PROZAC® are similar products. On a purely technical level they are different: HERBROZAC is a food and PROZAC® is a drug. See 21 U.S.C. § 321(f)(g)(l) (distinguishing between dietary supplements and drugs for purposes of Federal Food, Drug and Cosmetic Act); Dietary Supplement Health and Education Act of 1994, S. Rep. No. 103-410, pt. VIII, sec. 2(2)(A)-(B) (clarifying that dietary supplements are not drugs and should not be regulated as drugs). This is a critical distinction, moreover, because HERBRO-ZAC is not subject to the rigorous testing and approval process applied to drugs.
The fact that HERBROZAC and PROZAC® are not the
same
product does not end our inquiry, however, because we are concerned only with whether they are
similar.
Although its legal papers take a contrary position, Natural Answers would certainly have consumers believe that HERBROZAC and PROZAC® are similar products. Indeed, Natural Answers describes HERBROZAC as a “mood elevator,” the mirror image of anti-depressant, and markets it as an alternative to PROZAC®. Natural Answers’ dual-track conception of HERBROZAC — as a PROZAC® alternative for marketing purposes, but a dissimilar product for legal purposes — is disingenuous. Moreover, contrary to Natural Answers’ suggestion, our inquiry in comparing the two products is not whether they are interchangeable, but whether “the parties’ products are the kind the public might very well attribute to a single source (the plaintiff).”
International Kennel Club,
It is unlikely that HERBROZAC and PROZAC® would ever be used concurrently. As Lilly points out, there is some degree of danger that consumers suffering from self-diagnosed depression will view HERBROZAC as a PROZAC® substitute and never seek medical advice. However, a consumer must have a prescription from a doctor in order to obtain PROZAC®, and we have no doubt that doctors would experience little difficulty in .distinguishing between the two products. Thus, any consumer with access to PROZAC® would necessarily have the advice of a doctor, who presumably would .explain , the merits and demerits of each product. Accordingly, it is unlikely that HERBROZAC and PROZAC® would be used concurrently. This factor, therefore, weighs in favor of Natural Answers.
Although we will indulge in the assumption that doctors exercise great care in selecting medications for their patients, *464 the record contains scant evidence of the degree of care likely to be exercised by ordinary consumers. Natural Answers suggests that the legislative history of the Dietary Supplement Health and Education Act — which found that consumers generally believe that dietary supplements should not be regulated as drugs — is indicative of a high standard of care among consumers. See Dietary Supplement Health and Education Act of 1994, S. Rep. No. 103-410, pt. VIII, sec. 2(9)(B). In addition, Natural Answers asserts that its Web site, the only medium through which HERBROZAC is advertised, makes clear that the product is not associated with Lilly.
We are not at all sure that Natural Answers’ customers exercise greater than average care. Natural Answers would have us consider only the care exercised by doctors, but the first-line consumers of HERBROZAC are ordinary consumers, who may or may not seek medical advice before buying HERBROZAC. Indeed, Natural Answers’ strategy is to divert consumers away from doctors by “hav[ing] them go natural first and not go with drugs,” so we must look at the degree of care exercised by
all
consumers.
See Forum Corp. of N. Am.,
“The term ‘strength’ as applied to trademarks refers to the distinctiveness of the mark, or more precisely, its tendency to identify the goods sold under the mark as emanating from a particular ... source.”
Sands, Taylor & Wood Co. v. Quaker Oats Co.,
The record contains no evidence of actual consumer confusion, but Lilly cannot be expected to tender such evidence at this stage. When Lilly filed this lawsuit, Natural Answers had sold less than $2,000 worth of HERBROZAC, so it is not surprising that Lilly cannot identify consumers who were actually confused about the origin or sponsorship of HERBROZAC. Even a statistically reliable consumer survey would likely require a greater sampling than the total number of HERBRO-ZAC customers.
Despite these limitations, Judge Hamilton found a risk of “initial interest confusion.” Such confusion, which is actionable under the Lanham Act, occurs when a consumer is lured to a product by its similarity' to a known mark, even though the consumer realizes the true identity and origin of the product before consummating a purchase.
Dorr-Oliver,
*465
But we are concerned here with evidence of
actual
confusion, not a mere risk of confusion, and we find no such evidence in the record. The similarity of the two marks is a separate consideration in our analysis, and although it does create a risk of confusion, it does not constitute evidence of actual confusion. The same can be said of Natural Answers’ use of the “Prozac” metatag: it is evidence of Natural Answers’ intent,
see infra,
and .it creates a risk of confusion, but it is not evidence of actual confusion. Such evidence would most likely take the form of a consumer survey, which would not be limited to a sampling of HERBROZAC customers because “initial interest confusion” is complete prior to any actual purchase. Lilly failed to take such a survey, or to provide other evidence of actual confusion. So we must disagree with the district court that evidence of actual confusion indicates a likelihood of confusion. We have previously made clear, however, that evidence of actual confusion is not essential to a finding of a likelihood of confusion.
E.g., Computer Care v. Service Sys. Enter., Inc.,
The final factor for consideration is Natural Answers’ intent. Natural Answers urges us to drop this factor from our analysis, asserting that its intent (or lack thereof) to confuse consumers is not probative of whether consumers are likely to actually become confused. We disagree. The fact that one actively pursues an objective greatly increases the chances that the objective will be achieved, and we have no doubt that this general principle applies here. For this reason, a defendant’s intent is an “important factor,”
Computer Care,
Two facts point to the conclusion that Natural Answers intended to confuse consumers. First, Mr. Feinstein admitted that the name HERBROZAC was coined to remind consumers of PROZAC®, in accordance with Natural Answers’ pattern of adapting famous marks for use in its Herbseriptions line. Although Natural Answers now claims that the intent of the name is only to describe the general function of the product and to distinguish it from PROZAC®, we have a difficult time believing this innocent explanation. The HERBROZAC name does nothing — other than through its reference to the PROZAC® mark — to describe the function of “mood elevation.” If, at the conclusion of this case, Natural Answers is searching for a new name for its product that truly describes its function, it might come up with something like- “Natural Answers’ Herbal Mood Elevator,” a name that would describe the product’s function but not infringe upon Lilly’s mark.
The second fact probative of Natural Answers’ wrongful intent is its references to PROZAC® in the source codes of its Web site. The clear intent of this effort, whether or not it was successful, was to divert Internet users searching for information on PROZAC® to Natural Answers’ Web site. As the Ninth Circuit explained in
Brookfield Communications, Inc. v. West Coast Entertainment Corp.,
Having considered each of the.relevant factors in our likelihood of confusion analysis, we cannot say that the district court erred in finding such a likelihood. Although the district court improperly *466 weighed the evidence of actual confusion, we believe the other factors — especially the similarity of the marks, the strength of the PROZAC® mark, and Natural Answers’ intent to confuse — strongly support the district court’s ultimate conclusion. Accordingly, we affirm the district court’s preliminary injunction under the Lanham Act.
Lilly also brought a claim under the Trademark Dilution Act of 1995, which opens an alternative avénue of relief for the owners of famous marks. The Act provides:
The owner of a famous mark shall be entitled, subject to the principles of equity and upon such terms as the court deems reasonable, to an injunction against another person’s commercial use in commerce of a mark or trade name, if such use begins after the mark has become famous and causes dilution of the distinctive quality of the mark, and to obtain such other relief as is provided in this subsection.
15 U.S.C. § 1125(c)(1). Courts recognize two principal forms of dilution: tarnishing and blurring. Dilution by tarnishing occurs when a junior mark’s similarity to a famous mark causes consumers mistakenly to associate the famous mark with the defendant’s inferior or offensive product.
Panavision Int'l, L.P. v. Toeppen,
There are four elements to Lilly’s Trademark Dilution Act claim: (1) the PROZAC® mark is famous, (2) Natural Answers adopted its HERBROZAC name after the PROZAC® mark became famous, (3) use of the HERBROZAC name “causes dilution” of the PROZAC® mark, and (4) Natural Answers’ use of the HERBROZAC name is commercial and in commerce.
See
15 U.S.C. § 1125(c)(1);
Syndicate Sales, Inc. v. Hampshire Paper Corp.,
As a threshold issue, the parties dispute whether the “causes dilution” ele
*467
ment can be satisfied by evidence of a mere likelihood of dilution, or whether proof of actual dilution is required. The legislative history of the Act does not specifically address this question, and the circuit courts to have considered it are divided.
Compare Westchester Media v. PRL USA Holdings, Inc.,
In
Ringling Brothers,
the Fourth Circuit set out a cogent argument for a restrictive reading of the Trademark Dilution Act that requires the plaintiff to submit proof of actual economic harm. The court observed that state antidilution statutes — upon which the Trademark Dilution Act is based — typically prohibit the use of a mark that creates a “likelihood. of ... dilution of the distinctive quality of a [senior] mark.”
The Second Circuit rejected
Ringling Brothers
in
Nabisco,
observing that the Fourth Circuit’s reading of the statute would subject senior mark holders to un-compensable injury. After all, the primary remedy - of the Act is an injunction against future use of an offending mark; damages are permitted only when the defendant acts wilfully. 15 U.S.C. § 1125(c)(2). Thus, if the “causes dilution” element requires proof of actual economic harm, senior mark holders will be restrained from bringing suit prior to suffering an injury for which the Act will not compensate them in many circumstances.
Nabisco,
In addition, the Fourth Circuit’s interpretation of the Act holds plaintiffs to an impossible level of proof. In the case of an immensely successful product such as PROZAC®, it is possible that the distinctiveness of its mark could be diluted even as its sales are increasing, albeit not increasing as much as they would in the absence of the offending mark.
See Times Mirror Magazines,
How then, should we decide whether Lilly has demonstrated a likelihood of dilution? The Second Circuit adopted a number of factors from the much criticized concurrence in
Mead Data Central, Inc. v. Toyota Motor Sales, U.S.A., Inc.,
In suggesting a test for dilution under New York’s antidilution statute, the concurring judge in
Mead Data
identified the following pertinent considerations: (1) similarity of the marks, (2) similarity of the products covered by the marks, (3) sophistication of consumers, (4) predatory intent, (5) renown of the senior mark, and (6) renown of the junior mark.
Mead Data,
We already have addressed the similarity between the two marks at issue and concluded that they are highly similar. As for our second factor, PROZAC® has achieved substantial renown. As we noted earlier, PROZAC® has received an immense amount of attention from the news media. In addition to what we have already described, PROZAC® has been the subject of two national bestsellers (Peter D. Kramer’s “Listening to Prozac” (1993) and Elizabeth Wurtzel’s “Prozac Nation: Young and Depressed in America” (1994)) and segments on 60 Minutes, Good Morning America, and the Oprah Winfrey Show. According to a Baltimore Sun columnist, PROZAC® is “a designer label, a buzzword, a brand name familiar to ... Americans who have taken it, but also [to] those who wonder if they, too might find a cure for whatever ails them in the little green-and-off-white capsule.” Given this evidence, we cannot disagree with the district court’s conclusion that PROZAC® “has achieved extraordinary fame in American culture.” We therefore affirm the district court’s holding that Lilly has shown a likelihood of success in proving a likelihood of dilution.
We also affirm the district court’s assessment of the remaining preliminary injunction issues. Irreparable harm is generally presumed in cases of trademark infringement and dilution.
