Trademark Dilution and the Lanham Act: Understanding Protection for Famous Brands

“Trademark dilution protects famous marks from being misapplied to create an inferior brand or to lower brand value or, at least, brands' reputation (not when people are ignorant or not). The Lanham Act describes dilution as “lessening of the capacity of a famous mark to identify and distinguish goods or services.” 15 U.S.C. § 1125(c).”

Dilution law protects famous marks from unauthorized uses that blur or tarnish the mark, including applications that create inferior products or diminish the mark’s reputation, regardless of consumer confusion.

  • The Rational Basis of Trademark Protection Revisited: Putting the Dilution Doctrine into Context

    This Article’s thesis is that the dilution doctrine and the traditional tests for trademark infringement have the same rational basis – that they may all be coherently explained on the basis of the functional approach. To prove this the- sis, I will introduce two concepts: the “communication function” and “intrinsic reputation.” On the basis of these concepts, I will argue that trademarks could not fulfill their economic functions if they were not protected against dilution.
