INWOOD LABORATORIES, INC. v. IVES LABORATORIES, INC.

JUSTICE O'CONNOR delivered the opinion of the Court.

This action requires us to consider the circumstances under which a manufacturer of a generic drug, designed to duplicate the appearance of a similar drug marketed by a competitor under a registered trademark, can be held vicariously liable for infringement of that trademark by pharmacists who dispense the generic drug.

I

In 1955, respondent Ives Laboratories, Inc. (Ives), received a patent on the drug cyclandelate, a vasodilator used in long-term therapy for peripheral and cerebral vascular diseases. Until its patent expired in 1972, Ives retained the exclusive right to make and sell the drug, which it did under the registered trademark CYCLOSPASMOL.1 Ives marketed the drug, a white powder, to wholesalers, retail pharmacists, and hospitals in colored gelatin capsules. Ives arbitrarily selected a blue capsule, imprinted with "Ives 4124," for its 200 mg dosage and a combination blue-red capsule, imprinted with "Ives 4148," for its 400 mg dosage.

After Ives' patent expired, several generic drug manufacturers, including petitioners Premo Pharmaceutical Laboratories, Inc., Inwood Laboratories, Inc., and MD Pharmaceutical Co., Inc. (collectively the generic manufacturers), began marketing cyclandelate.2 They intentionally copied the appearance of the CYCLOSPASMOL capsules, selling cyclandelate in 200 mg and 400 mg capsules in colors identical to those selected by Ives.3

The marketing methods used by Ives reflect normal industry practice. Because cyclandelate can be obtained only by prescription, Ives does not direct its advertising to the ultimate consumer. Instead, Ives' representatives pay personal visits to physicians, to whom they distribute product literature and "starter samples." Ives initially directed these efforts toward convincing physicians that CYCLOSPASMOL is superior to other vasodilators. Now that its patent has expired and generic manufacturers have entered the market, Ives concentrates on convincing physicians to indicate on prescriptions that a generic drug cannot be substituted for CYCLOSPASMOL.4

The generic manufacturers also follow a normal industry practice by promoting their products primarily by distribution of catalogs to wholesalers, hospitals, and retail pharmacies, rather than by contacting physicians directly. The catalogs truthfully describe generic cyclandelate as "equivalent" or "comparable" to CYCLOSPASMOL.5 In addition, some of the catalogs include price comparisons of the generic drug and CYCLOSPASMOL and some refer to the color of the generic capsules. The generic products reach wholesalers, hospitals, and pharmacists in bulk containers which correctly indicate the manufacturer of the product contained therein.

A pharmacist, regardless of whether he is dispensing CYCLOSPASMOL or a generic drug, removes the capsules from the container in which he receives them and dispenses them to the consumer in the pharmacist's own bottle with his own label attached. Hence, the final consumer sees no identifying marks other than those on the capsules themselves.

A

Ives instituted this action in the United States District Court for the Eastern District of New York under §§ 32 and 43(a) of the Trademark Act of 1946 (Lanham Act), 60 Stat. 427, as amended, 15 U. S. C. § 1051 et seq., and under New York's unfair competition law, N. Y. Gen. Bus. Law § 368-d (McKinney 1968).6

Ives' claim under § 32, 60 Stat. 437, as amended, 15 U. S. C. § 1114,7 derived from its allegation that some pharmacists had dispensed generic drugs mislabeled as CYCLOSPASMOL.8 Ives contended that the generic manufacturers' use of look-alike capsules and of catalog entries comparing prices and revealing the colors of the generic capsules induced pharmacists illegally to substitute a generic drug for CYCLOSPASMOL and to mislabel the substitute drug CYCLOSPASMOL. Although Ives did not allege that the petitioners themselves applied the Ives trademark to the drug products they produced and distributed, it did allege that the petitioners contributed to the infringing activities of pharmacists who mislabeled generic cyclandelate.

Ives' claim under § 43(a), 60 Stat. 441, 15 U. S. C. § 1125(a),9 alleged that the petitioners falsely designated the origin of their products by copying the capsule colors used by Ives and by promoting the generic products as equivalent to CYCLOSPASMOL. In support of its claim, Ives argued that the colors of its capsules were not functional10 and that they had developed a secondary meaning for the consumers.11

Contending that pharmacists would continue to mislabel generic drugs as CYCLOSPASMOL so long as imitative products were available, Ives asked that the court enjoin the petitioners from marketing cyclandelate capsules in the same colors and form as Ives uses for CYCLOSPASMOL. In addition, Ives sought damages pursuant to § 35 of the Lanham Act, 60 Stat. 439, as amended, 15 U. S. C. § 1117.

B

The District Court denied Ives' request for an order preliminarily enjoining the petitioners from selling generic drugs identical in appearance to those produced by Ives. 455 F.Supp. 939 (1978). Referring to the claim based upon § 32, the District Court stated that, while the "knowing and deliberate instigation" by the petitioners of mislabeling by pharmacists would justify holding the petitioners as well as the pharmacists liable for trademark infringement, Ives had made no showing sufficiently to justify preliminary relief. Id., at 945. Ives had not established that the petitioners conspired with the pharmacists or suggested that they disregard physicians' prescriptions.

The Court of Appeals for the Second Circuit affirmed. 601 F.2d 631 (1979). To assist the District Court in the upcoming trial on the merits, the appellate court defined the elements of a claim based upon § 32 in some detail. Relying primarily upon Coca-Cola Co. v. Snow Crest Beverages, Inc., 64 F.Supp. 980 (Mass. 1946), aff'd, 162 F.2d 280 (CA1), cert. denied, 332 U.S. 809 (1947), the court stated that the petitioners would be liable under § 32 either if they suggested, even by implication, that retailers fill bottles with generic cyclandelate and label the bottle with Ives' trademark or if the petitioners continued to sell cyclandelate to retailers whom they knew or had reason to know were engaging in infringing practices. 601 F. 2d, at 636.

C

After a bench trial on remand, the District Court entered judgment for the petitioners. 488 F.Supp. 394 (1980). Applying the test approved by the Court of Appeals to the claim based upon § 32, the District Court found that the petitioners had not suggested, even by implication, that pharmacists should dispense generic drugs incorrectly identified as CYCLOSPASMOL.12

In reaching that conclusion, the court first looked for direct evidence that the petitioners intentionally induced trademark infringement. Since the petitioners' representatives do not make personal visits to physicians and pharmacists, the petitioners were not in a position directly to suggest improper drug substitutions. Cf. William R. Warner & Co. v. Eli Lilly & Co., 265 U.S. 526, 530-531 (1924); Smith, Kline & French Laboratories v. Clark & Clark, 157 F.2d 725, 731 (CA3), cert. denied, 329 U.S. 796 (1946). Therefore, the court concluded, improper suggestions, if any, must have come from catalogs and promotional materials. The court determined, however, that those materials could not "fairly be read" to suggest trademark infringement. 488 F. Supp., at 397.

The trial court next considered evidence of actual instances of mislabeling by pharmacists, since frequent improper substitutions of a generic drug for CYCLOSPASMOL could provide circumstantial evidence that the petitioners, merely by making available imitative drugs in conjunction with comparative price advertising, implicitly had suggested that pharmacists substitute improperly. After reviewing the evidence of incidents of mislabeling, the District Court concluded that such incidents occurred too infrequently to justify the inference that the petitioners' catalogs and use of imitative colors had "impliedly invited" druggists to mislabel. Ibid. Moreover, to the extent mislabeling had occurred, the court found it resulted from pharmacists' misunderstanding of the requirements of the New York Drug Substitution Law, rather than from deliberate attempts to pass off generic cyclandelate as CYCLOSPASMOL. Ibid.

The District Court also found that Ives failed to establish its claim based upon § 43(a). In reaching its conclusion, the court found that the blue and blue-red colors were functional to patients as well as to doctors and hospitals: many elderly patients associate color with therapeutic effect; some patients commingle medications in a container and rely on color to differentiate one from another; colors are of some, if limited, help in identifying drugs in emergency situations; and use of the same color for brand name drugs and their generic equivalents helps avoid confusion on the part of those responsible for dispensing drugs. Id., at 398-399. In addition, because Ives had failed to show that the colors indicated the drug's origin, the court found that the colors had not acquired a secondary meaning. Id., at 399.

Without expressly stating that the District Court's findings were clearly erroneous, and for reasons which we discuss below, the Court of Appeals concluded that the petitioners violated § 32. 638 F.2d 538 (1981). The Court of Appeals did not reach Ives' other claims. We granted certiorari, 454 U.S. 891 (1981), and now reverse the judgment of the Court of Appeals.

A

As the lower courts correctly discerned, liability for trademark infringement can extend beyond those who actually mislabel goods with the mark of another. Even if a manufacturer does not directly control others in the chain of distribution, it can be held responsible for their infringing activities under certain circumstances. Thus, if a manufacturer or distributor intentionally induces another to infringe a trademark, or if it continues to supply its product to one whom it knows or has reason to know is engaging in trademark infringement, the manufacturer or distributor is contributorially responsible for any harm done as a result of the deceit.13 See William R. Warner & Co. v. Eli Lilly & Co., supra; Coca-Cola Co. v. Snow Crest Beverages, Inc., supra.

It is undisputed that those pharmacists who mislabeled generic drugs with Ives' registered trademark violated § 32.14 However, whether these petitioners were liable for the pharmacists' infringing acts depended upon whether, in fact, the petitioners intentionally induced the pharmacists to mislabel generic drugs or, in fact, continued to supply cyclandelate to pharmacists whom the petitioners knew were mislabeling generic drugs. The District Court concluded that Ives made neither of those factual showings.

B

In reviewing the factual findings of the District Court, the Court of Appeals was bound by the "clearly erroneous" standard of Rule 52(a), Federal Rules of Civil Procedure. Pullman-Standard v. Swint, ante, p. 273. That Rule recognizes and rests upon the unique opportunity afforded the trial court judge to evaluate the credibility of witnesses and to weigh the evidence. Zenith Radio Corp. v. Hazeltine Research, Inc., 395 U.S. 100, 123 (1969). Because of the deference due the trial judge, unless an appellate court is left with the "definite and firm conviction that a mistake has been committed," United States v. United States Gypsum Co., 333 U.S. 364, 395 (1948), it must accept the trial court's findings.15

IV

In reversing the District Court's judgment, the Court of Appeals initially held that the trial court failed to give sufficient weight to the evidence Ives offered to show a "pattern of illegal substitution and mislabeling in New York. . . ."16 638 F. 2d, at 543. 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.

Next, after completing its own review of the evidence, the Court of Appeals concluded that the evidence was "clearly sufficient to establish a § 32 violation." Ibid. In reaching its conclusion, the Court of Appeals was influenced by several factors. First, it thought the petitioners reasonably could have anticipated misconduct by a substantial number of the pharmacists who were provided imitative, lower priced products which, if substituted for the higher priced brand name without passing on savings to consumers, could provide an economic advantage to the pharmacists. Ibid.17 Second, it disagreed with the trial court's finding that the mislabeling which did occur reflected confusion about state law requirements. Id., at 544.18 Third, it concluded that illegal substitution and mislabeling in New York are neither de minimis nor inadvertent. Ibid.19 Finally, the Court of Appeals indicated it was further influenced by the fact that the petitioners did not offer "any persuasive evidence of a legitimate reason unrelated to CYCLOSPASMOL" for producing an imitative product. Ibid.20

Each of those conclusions is contrary to the findings of the District Court. 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 another construction, resolve the ambiguities differently, and find a more sinister cast to actions which the District Court apparently deemed innocent." United States v. Real Estate Boards, 339 U.S. 485, 495 (1950).

V

The Court of Appeals erred in setting aside findings of fact that were not clearly erroneous. Accordingly, the judgment of the Court of Appeals that the petitioners violated § 32 of the Lanham Act is reversed.

Although the District Court also dismissed Ives' claims alleging that the petitioners violated § 43(a) of the Lanham Act and the state unfair competition law, the Court of Appeals did not address those claims. Because § 43(a) prohibits a broader range of practices than does § 32, as may the state unfair competition law, the District Court's decision dismissing Ives' claims based upon those statutes must be independently reviewed. Therefore, we remand to the Court of Appeals for further proceedings consistent with this opinion.

Reversed and remanded.

JUSTICE WHITE, with whom JUSTICE MARSHALL joins, concurring in the result.

We granted certiorari in these cases in order to review the legal standard employed by the Second Circuit in finding that a generic drug manufacturer is vicariously liable for trademark infringement committed by pharmacists who dispense the generic drug. The Court implicitly endorses the legal standard purportedly employed by the Court of Appeals, ante, at 853-854, but finds that the court erred in setting aside factual findings that were not clearly erroneous. The question whether the Court of Appeals had misapplied the clearly-erroneous rule, however, was not presented in the petitions for certiorari. This was conceded at oral argument.1 Tr. of Oral Arg. 69. Our Rule 21.1(a) states that "[o]nly the questions set forth in the petition or fairly included therein will be considered by the Court." The majority suggests no reason for ignoring our own Rule. Furthermore, if the issue presented in the petitions for certiorari had been whether the clearly-erroneous standard, although properly invoked, was erroneously applied, it is doubtful in my mind that this fact-bound issue would have warranted certiorari. I nevertheless concur in reversal because I believe that the Court of Appeals has watered down to an impermissible extent the standard for finding a violation of § 32 of the Lanham Act, 15 U. S. C. § 1114.

In its first opinion in this litigation, the Court of Appeals indicated that a "manufacturer or wholesaler would be liable under § 32 if he suggested, even if only by implication, that a retailer fill a bottle with the generic capsules and apply Ives' mark to the label, or continued to sell capsules containing the generic drug which facilitated this to a druggist whom he knew or had reason to know was engaging in the practices just described." 601 F.2d 631, 636 (1979) (Ives II). The District Court applied this test but concluded that no violation of § 32 had been shown. On appeal after trial, a majority of the Second Circuit found defendants liable for contributory infringement by revising and expanding the doctrine of contributory trademark infringement. 638 F.2d 538 (1981) (Ives IV):

Ives II required a showing that petitioners intended illegal substitution or knowingly continued to supply pharmacists palming off generic cyclandelate as CYCLOSPASMOL; Ives IV was satisfied merely by the failure to "reasonably anticipate" that illegal substitution by some pharmacists was likely. In my view, this is an erroneous construction of the statutory law governing trademark protection.

William R. Warner & Co. v. Eli Lilly & Co., 265 U.S. 526 (1924), made clear that a finding of contributory infringement requires proof of either an intent to induce illegal substitution or continued sales to particular customers whom the manufacturer knows or should know are engaged in improper palming off. In that case, it was shown that the manufacturer's salesmen actively induced, either in direct terms or by insinuation, the filling of requests for Coco-Quinine with Quin-Coco. "The wrong was in designedly enabling the dealers to palm off the preparation as that of the respondent."2 Id., at 530. Coca-Cola Co. v. Snow Crest Beverages, Inc., 64 F.Supp. 980, 989 (Mass. 1946), aff'd, 162 F.2d 280 (CA1), cert. denied, 332 U.S. 809 (1947), the case upon which the Court of Appeals relied in Ives II, stands for this very proposition. There was no contributory infringement in Snow Crest's manufacture of a product identical in appearance to that of Coca-Cola. Judge Wyzanski observed that

These cases reflect the general consensus. 2 J. McCarthy, Trademarks and Unfair Competition § 25:2 (1973) ("[T]he supplier's duty does not go so far as to require him to refuse to sell to dealers who merely might pass off its goods"). The mere fact that a generic drug company can anticipate that some illegal substitution will occur to some unspecified extent, and by some unknown pharmacists, should not by itself be a predicate for contributory liability. I thus am inclined to believe that the Court silently acquiesces in a significant change in the test for contributory infringement.

Diluting the requirement for establishing a prima facie case of contributory trademark infringement is particularly unjustified in the generic drugs field. Preventing the use of generic drugs of the same color to which customers had become accustomed in their prior use of the brand name product interferes with the important state policy, expressed in New York and 47 other States, of promoting the substitution of generic formulations. See Warner, Consumer Protection and Prescription Drugs: The Generic Drug Substitution Laws, 67 Ky. L. J. 384 (1978-1979).

The Court of Appeals concluded that there was no "persuasive evidence of a legitimate reason" for petitioners to use imitative colors. The District Court, however, had expressly found that for purposes of § 43(a), the capsule colors were functional. With respect to functionality, I fully agree with the Court that the Court of Appeals erred in setting aside factual findings without finding that they were clearly erroneous. The District Court found that capsule color was functional in several respects: patient anxiety and confusion were likely if accustomed medicine were dispensed in a different color; capsule colors assist patients in identifying the correct pill to take; standard colors help physicians identify the drug involved in case of overdose.3 Clearly, the Court of Appeals could not reject these findings merely because it viewed the evidence as less persuasive than did the District Court. Rule 52(a) imposes a stricter standard.

Finally, although the Court states that a "finding of functionality may also be relevant to an action involving § 32," it does not explicate the relationship of functionality in a § 32 case. It is my view that a finding of functionality offers a complete affirmative defense to a contributory infringement claim predicated solely on the reproduction of a functional attribute of the product. A functional characteristic is "an important ingredient in the commercial success of the product," 601 F. 2d, at 643, and, after expiration of a patent, it is no more the property of the originator than the product itself. It makes no more sense to base contributory infringement upon the copying of functional colors than on the petitioners' decision to use the same formulation of the drug, or even to market the generic substitute in the first place. To be sure, the very existence of generic drugs "facilitates" illegal substitution. But Ives no longer has a patent for cyclandelate, "and the defendants have a right to reproduce it as nearly as they can." Saxlehner v. Wagner, 216 U.S. 375, 380 (1910) (Holmes, J.). Reproduction of a functional attribute is legitimate competitive activity.

I am also mindful that functionality is a defense to a suit under § 43(a) of the Lanham Act alleging damages from a competitor's "false designation of origin" on a good.4 The use of a product or package design that is so similar to that of another producer that it is likely to confuse purchasers as to the product's source may constitute "false designation of origin" within the meaning of the Act.5 As the Court of Appeals noted in Ives II, § 43(a) "goes beyond § 32 in making certain types of unfair competition federal statutory torts," 601 F. 2d, at 641. Section 43(a) offers the direct protection of Ives' interest in this case, and it is not surprising that the alleged § 43(a) violation was the primary claim in this litigation, as it has been in other cases of this genre. It would be anomalous for the imitation of a functional feature to constitute contributory infringement for purposes of § 32, while the same activity is not a "false designation of origin" under § 43(a).6

I would reverse the decision of the Court of Appeals and remand for review of the District Court's findings consistent with the principles stated above.

JUSTICE REHNQUIST, concurring in the result.

I agree that the judgment of the Court of Appeals should be reversed. That court set aside factual findings of the District Court without having found them to be clearly erroneous as required by Rule 52(a) of the Federal Rules of Civil Procedure. I disagree, however, with the Court's determining for itself that the findings of the District Court were not clearly erroneous. I think in the usual case this is a question best decided by the courts of appeals, who have a good deal more experience with the application of this principle than we do, and I see no reason to make an exception in this case.

I also assume, correctly I hope, that the Court's discussion of appellate review of trial court findings in bench trials, ante, at 855, is limited to cases in which the appellate court has not found the trial court findings to be "clearly erroneous." United States v. United States Gypsum Co., 333 U.S. 364 (1948), upon which the Court relies, establishes the authority of a reviewing court to make its own findings, contrary to those of the trial court, where it has determined the latter to be "clearly erroneous."

I agree with the Court that these cases should be remanded to the Court of Appeals to review the District Court's dismissal of respondent's claims under § 43(a) of the Lanham Act and its state-law claims.
