Essential to Use

Definition

Essential to use refers to the fundamental aspect of a product's design that is necessary for its function, particularly in relation to the functionality doctrine in trademark law. This concept determines whether a feature of a product can be protected as a trademark or if it is merely a functional aspect that should remain available for public use. When a feature is deemed essential to use, it means that excluding others from using that feature would impede competition and innovation.
