The Eighth Circuit Court recently upheld a decision that denied trademark protection for a water hose manufacturer, ruling that the chartreuse color of its hoses was a functional attribute rather than a distinctive brand mark. This decision arose from a case where the hose manufacturer claimed that a competitor infringed on its trademark by using a similar color for their products.
The court concurred with a previous ruling that the color’s function was primarily utilitarian. The bright chartreuse was considered essential for visibility in gardens and construction sites, enhancing safety by making hoses easily noticeable. Due to this functional significance, the court ruled that the color could not serve as a trademark. The ruling aligns with established principles that prohibit functional features from being trademarked, a stance taken to prevent monopolization of features that improve product utility.
The decision underscores the challenge companies face in differentiating products through color alone. To secure trademark protection, they must demonstrate that a color has acquired “secondary meaning” linked to the brand, rather than serving a functional purpose. Without this distinction, a color remains a functional aspect rather than a trademarkable feature, as further elaborated in discussions by JD Supra.
This ruling could have broader implications for industries relying on color for branding. Companies must carefully consider whether their color-based trademarks can be protected. The case illustrates the importance of proving a non-functional role for color in branding strategies, to prevent competitive restrictions purely based on aesthetic choices. For legal professionals, this emphasizes the need to carefully analyze trademark strategies to ensure compliance with the functionality doctrine.
