Trademark infringement occurs when a third party uses a mark in a way that infringes upon a trademark owner’s exclusive right and use of a trademark. Often, the third party will use a similar mark in a way that confuses consumers as to the source of the goods and services. For example, a fast food restaurant named “Wendi’s” would likely cause confusion with “Wendy’s.” Trademark infringement can occur only when it is likely that consumers will be confused as to the source of the goods. The purpose of this article is to examine the test and factors that courts use to determine if such infringement exists.
Many courts have developed a balancing test to determine if a mark infringes on another. This balancing test has largely grown from the seminal case Polaroid Corp. v. Polarad Elect. Corp., 287 F.2d 492 (2nd Cir. 1961). In that case, the court identified several variables to consider when assessing if a mark is infringing on another mark. This balancing test seeks to determine if consumers would likely be confused as to the source of the marks. If the test favors that confusion would likely result, then the court will likely rule that infringement exists. On the other hand, if confusion is unlikely or minimal, the court will likely rule against infringement.Continue Reading Trademark Infringement: Factors Considered in Consumer Confusion
