Legal Definitions - colorable-imitation test

The colorable-imitation test is a legal standard used in trademark law to determine if one product or service's branding (such as its name, logo, or packaging) is so similar to another's that it is likely to confuse consumers. The test asks whether an average person, encountering the two items at different times and without the opportunity to compare them side-by-side, would reasonably mistake one for the other or believe they come from the same source. If a court finds that the imitation is "colorable"—meaning it has enough resemblance to potentially deceive—it suggests a trademark violation.

• Example 1 (Food & Beverage): Imagine a new brand of sparkling water called "FizzPop" that uses a distinctive blue and silver can design with a stylized bubble logo. A well-established sparkling water brand, "PopFizz," has been using a very similar blue and silver color scheme and a nearly identical bubble logo for years. A court applying the colorable-imitation test would consider whether a shopper, seeing "FizzPop" on a store shelf without "PopFizz" next to it, might assume it's a new flavor or product line from the "PopFizz" company, or simply confuse the two brands due to the similar visual cues and names. The test doesn't require the designs to be identical, only similar enough to cause confusion in a typical purchasing situation.

• Example 2 (Apparel & Accessories): Consider a new clothing company that releases a line of athletic shoes featuring a prominent "swoosh-like" checkmark logo on the side, which closely resembles the iconic "swoosh" logo of a globally recognized sportswear brand. Under the colorable-imitation test, a court would assess if an ordinary consumer, seeing these shoes in a store or online, would mistakenly believe they are genuine products from the famous sportswear brand, or that the famous brand has endorsed or collaborated with the new company. The key is whether the resemblance is strong enough to create a false impression of origin or association, even if the consumer isn't directly comparing them to the authentic item.

• Example 3 (Software & Applications): A new mobile application designed for managing personal finances uses a user interface, icon set, and specific feature names that are strikingly similar to a very popular and established personal finance app. Applying the colorable-imitation test, a court would evaluate whether a user, downloading or opening the new app, might reasonably think it's an update, a spin-off, or even the original app, simply because its appearance and functionality mimic the well-known one so closely. The test aims to prevent the new app from unfairly benefiting from the established app's reputation and brand recognition by creating a confusingly similar user experience.
