Rule of Law:
A manufacturer who intentionally copies a competitor's product and then encourages retailers to substitute its product for the competitor's is liable for unfair competition, even if the competitor's product name is merely descriptive and not a protectable trademark.
Facts:
- In 1899, Eli Lilly & Co. began manufacturing and selling a liquid quinine preparation containing chocolate and yerba-santa under the name 'Coco-Quinine'.
- The chocolate ingredient served to give the product a distinctive color and flavor, as well as to help suspend the quinine.
- In 1906, a company under the same ownership as William R. Warner & Co. began making a substantially similar liquid quinine preparation marketed as 'Quin-Coco'.
- Warner manufactured its 'Quin-Coco' to be indistinguishable from Lilly's 'Coco-Quinine' in ordinary sight and taste.
- Warner's salesmen promoted 'Quin-Coco' to druggists by highlighting its identical nature to 'Coco-Quinine' and its lower price, suggesting or insinuating that it could be substituted to fill prescriptions for 'Coco-Quinine'.
- This marketing strategy resulted in numerous instances of retail druggists 'passing off' Warner's product as Lilly's to the final consumers.
Procedural Posture:
- Eli Lilly & Co. sued William R. Warner & Co. in the U.S. District Court for the Eastern District of Pennsylvania, alleging trademark infringement and unfair competition.
- The District Court, as the court of first instance, ruled in favor of Warner on both claims.
- Eli Lilly & Co., as appellant, appealed the decision to the U.S. Court of Appeals.
- The Court of Appeals affirmed the District Court's ruling on trademark infringement but reversed on the issue of unfair competition, finding in favor of Lilly.
- William R. Warner & Co., as petitioner, sought review from the U.S. Supreme Court.

Issue:
Does a manufacturer engage in unfair competition when it intentionally copies the physical appearance and qualities of a competitor's unpatented product and encourages retailers to substitute its product for the competitor's, thereby deceiving the ultimate consumer?
Opinions:
Majority - Mr. Justice Sutherland
Yes, a manufacturer engages in unfair competition by intentionally copying a competitor's product and encouraging its substitution. While the court agrees that the name 'Coco-Quinine' is descriptive of its ingredients and thus not a protectable trademark, the claim of unfair competition is valid. The essence of the wrong is not the imitation of the product itself, as anyone is free to manufacture an unpatented formula. The wrong lies in selling one's goods as those of a competitor. Warner did not merely copy Lilly's product; it availed itself of the favorable reputation Lilly had built by using the identical appearance to enable and encourage druggists to 'palm off' the cheaper Quin-Coco on unsuspecting consumers who asked for Coco-Quinine. That the druggists themselves were not deceived is irrelevant; Warner is liable because it induced the fraud and furnished the means to accomplish it. The appropriate remedy is not to ban Warner from using chocolate, which serves a functional purpose, but to require labeling that clearly distinguishes its product and explicitly states it is not to be substituted for Coco-Quinine.
Analysis:
This case establishes a crucial distinction between lawful imitation and unlawful unfair competition. It clarifies that even when a product's name or features are not protected by trademark or patent law, a competitor cannot use imitation as a tool for deception. The precedent holds that liability for 'passing off' can attach to a manufacturer who knowingly enables downstream retailers to defraud the end consumer. The decision's significance lies in protecting a business's goodwill and reputation against fraudulent marketing practices, shifting the focus from the act of copying to the deceptive intent and effect of the sales methods used.
