Section 2(f) of the Lanham Act allows for the registration of descriptive trademarks that have acquired distinctiveness through secondary meaning. This means that even if a mark initially describes a product or service, it can still be trademarked if consumers have come to associate that mark with a particular source due to its extensive use over time. Understanding this concept is crucial for navigating the complexities of trademark registration, especially when dealing with office actions, color marks, and potential bars to registration.
