trademark dilution

Trademark dilution occurs when a famous trademark's uniqueness or value is weakened due to its use by others, even without causing confusion among consumers. There are two main types: dilution by blurring, which diminishes the trademark's distinctiveness, and dilution by tarnishment, which harms its reputation. For example, if a well-known brand is associated with a poor-quality product, it tarnishes that brand’s image. Trademark dilution laws protect famous brands from being diminished or harmed, ensuring they maintain their strong identity and reputation in the marketplace.
