Through Trademark

If the respective marks and products or services are entirely dissimilar, trademark infringement may still be established if the registered mark is well known pursuant to the Paris Convention. In the United States, a cause of action for use of a mark for such dissimilar services is called trademark dilution.

In some jurisdictions a party other than the owner (e.g., a licensee) may be able to pursue trademark infringement proceedings against an infringer if the owner fails to do so.

Likelihood of confusion

Section 32 of the Lanham Act states that those who use similar or identical trademarks, products, or services, to those already registered with the USPTO in such a way as "likely to cause confusion, . . . cause mistake, or to deceive. . . shall be liable in a civil action by the registrant . . . ." Where the respective marks, products, or services are not identical, similarity will generally be assessed by reference to whether there is a likelihood of confusion that consumers will believe the products or services originated from the trademark owner.

Likelihood of confusion factors

A typical likelihood of confusion test balances a variety of factors, none of which is dispositive on its own. While each jurisdiction uses a slightly different test, every test considers (1) whether and to what extent the alleged infringer intended to infringe on the senior user's valid trademark rights, (2) evidence of any consumer confusion, and (3) factors that speak to the economic relationship between the consuming public and the two marks, products, or services.

The most famous of the foregoing tests is the one employed by the United States Court of Appeals for the Federal Circuit (the "DuPont" Factors). However, this is because it is the test used by USPTO when assessing the registrability of a mark upon application. In any legal action for trademark infringement in the United States, the court will apply the test of the circuit in which it is located.

Types of confusion

Courts assess likelihood of confusion in various contexts, including prior to the sale (also known as initial interest confusion), at the point of sale, and post-sale. Confusion may also be direct or reverse, depending on who the senior and junior user of the marks are.

Point-of-sale confusion

The most typical form of trademark infringement is point-of-sale confusion, which occurs when a consumer mistakenly believes that their product or service is from a company or brand in which it is not. This type of infringement involves a defendant "passing off" a good or service utilizing a trademark that belongs to the plaintiff, usually with the intent of deceiving consumers into thinking that the good or service originated with the plaintiff.

For example, in McDonald's Corp. v. Druck and Gerner, D.D.S., P.C., McDonald's sued McDental, a dental services provider operated by two dentists, for trademark infringement. McDonald's presented evidence that it owned trademark rights in a family of marks beginning with the prefix “Mc,” that there was widespread public familiarity with that family of marks, and that survey evidence established that confusion was likely to occur from the use of the McDental name. McDental's owners denied any intention to evoke McDonald's marks in their adoption of the McDental name, alleging that they had never perceived or heard anyone else perceive an association between the two marks. The United States District Court for the Northern District of New York found that the similarity between the McDental name and McDonald's family of brands beginning with “Mc” was obvious. The court held that McDonald's had shown that a likelihood of confusion existed, warranting the issuance of an injunction.

Initial interest confusion

Initial interest confusion occurs when an allegedly improper use of a trademark attracts potential purchasers to consider products or services provided by the infringer (bait-and-switch). Under the Lanham Act, a plaintiff may bring a trademark infringement claim against a defendant for creating consumer confusion prior to the point of sale, even if the consumer confusion is resolved before the sale goes through.

For example, in Playboy Enterprises, Inc. v. Netscape Communications Corp., Playboy sued Netscape for selling banner ads using trademarked terms "playboy" and "playmate." The United States Court of Appeals for the Ninth Circuit held that Playboy was likely to show that consumers may be attracted to competitors' products by free riding Playboy's reputation when using the trademarks "playboy" and "playmate", even if the consumers are well aware that they are not buying services from Playboy.

Post-sale confusion

Post-sale confusion occurs when the use of a trademark leads individuals of the general public (other than the purchaser) to mistakenly believe that a product was manufactured by the trademark holder. Thus, for the purposes of a likelihood of confusion analysis, the relevant audience may not be the targeted purchasers at all, but rather the general public, otherwise known as the "person on the street."

As articulated by the United States Court of Appeals for the Second Circuit, trademark law protects the public from incurring harms caused by post-sale confusion: "Trademark laws exists to protect the public from confusion. The creation of confusion in the post-sale context can be harmful in that if there are too many knockoffs in the market, sales of the original may decline because the public is fearful that what they are purchasing may not be an original. Furthermore, the public may be deceived in the resale market if it requires expertise to distinguish between an original and a knockoff."

For example, in Ferrari S.P.A. Esercizio v. Roberts, Ferrari S.P.A. Esercizio, a luxury-automobile manufacturer with a reputation for producing exclusive vehicles with distinctive designs, brought a trademark infringement suit against Carl Roberts after Roberts began manufacturing and selling kits that would allow budget-conscious car enthusiasts to copy the exterior designs of Ferrari (e.g., the Daytona Spyder, the Testarossa) onto the undercarriage of less expensive vehicles. Although Roberts has shown that confusion did not exist at the point of sale, the United States Court of Appeals for the Sixth Circuit concluded that allowing the kits to enter into commerce would dilute the Ferrari brand by diminishing the perceived exclusivity and quality that make the Daytona Spyder and Testarossa attractive to consumers. The court further held that the kits were designed to perfectly replicate the exterior of Ferrari's vehicles, and there was a strong likelihood of post-sale customer confusion. The Sixth Circuit held that Roberts's kits infringed upon the distinctive trade dress of Ferrari's vehicles, and a permanent injunction against Roberts was affirmed.

Direct confusion

Direct confusion occurs when consumers believe that the goods or services of a later (junior) trademark user come from, or are sponsored by, the prior (senior) trademark holder. In cases of direct confusion, the junior user is said to free ride on the reputation and goodwill of the senior user. Direct confusion typically occurs if the senior user is a much larger or better-known producer than the junior user.

Reverse confusion

Reverse confusion occurs if consumers incorrectly think that a later (junior) trademark user is the source of the prior (senior) trademark user's products or services. Reverse confusion typically occurs if the junior user is a much larger or better-known producer than the senior user.

Reverse-confusion claims exist to prevent big companies from stealing marks or brands from existing, smaller companies. Factors contributing to a likelihood of reverse confusion include: (1) similarity between the senior and junior user's marks, (2) the conceptual strength or uniqueness of the senior user's mark and the commercial strength or public awareness of the junior user's mark, (3) consumer attentiveness to the product, (4) the length of time junior user has used the mark without causing confusion, (5) whether the junior user intended to cause confusion, (6) evidence of actual confusion, (7) trade and advertising channels for the competing products, (8) the similarity of the manufacturers’ sales efforts, (9) the competing products’ similarity in the minds of consumers, and (10) facts suggesting that consumers would expect the junior user to manufacture both products or expand into the senior user's market.
