Ciba-Geigy AG v Allergan Inc

The dispute before the Federal Court of Australia concerned allegations of misleading and deceptive conduct and passing off, brought by Ciba-Geigy AG against Allergan Inc. Ciba-Geigy, the proprietor of the trade mark "VISINE" for eye drops, alleged that Allergan's use of the trade mark "VISINE" in relation to its own eye drops constituted a contravention of section 52 of the Trade Practices Act 1974 (Cth) and the tort of passing off.

The central legal issues for determination by the Court were whether Allergan's use of the "VISINE" mark was likely to deceive or cause confusion among consumers, thereby misleading them into believing that Allergan's product was associated with or originated from Ciba-Geigy. This involved an assessment of the distinctiveness of the "VISINE" mark, the nature of the goods in question, and the potential for confusion in the marketplace.

Justice Vija Zars reasoned that the "VISINE" mark had acquired a significant degree of distinctiveness in the Australian market through extensive use and advertising by Ciba-Geigy. The Court found that Allergan's use of the identical mark on identical goods was likely to cause deception and confusion, leading consumers to believe that Allergan's product was the same as or connected to Ciba-Geigy's well-established "VISINE" eye drops. This conduct was held to constitute both misleading and deceptive conduct under the Trade Practices Act and passing off at common law.

The Court ordered that Allergan Inc. be restrained from using the trade mark "VISINE" in relation to eye drops and awarded Ciba-Geigy AG its costs.
