Functionality defense

Definition

The functionality defense is a legal principle in trademark law that asserts that a product feature is not eligible for trademark protection if it is deemed functional. This means that if a design or feature is essential to the use or purpose of a product, it cannot be registered as a trademark. The concept plays a critical role in ensuring that trademarks do not grant monopolies over useful product features, allowing competitors to create similar products without infringing on trademark rights.
