The presumption of validity is a legal principle that establishes a registered trademark as inherently valid and protected under law until proven otherwise. This concept serves to bolster the enforceability of trademarks, allowing the registrant to take action against potential infringers without immediately having to prove the mark's validity, as registration provides a foundation of legal protection. It distinguishes between federal and state registration by offering stronger presumptive rights at the federal level, making it easier for trademark owners to defend their rights in court.
