Under Armour Inc. wants to protect its “I will” catchphrase.
The athletic clothing maker, based in Baltimore, has filed a trademark infringement suit against Nike Inc., claiming its rival has inappropriately used variations of the phrase in its marketing.
Under Armour says that since late last year, Nike, based in Portland, has launched an advertising campaign using phrases like “I will protect my home court,” and “I will finish what I started.”
Under Amour says such use of “I will” is “likely to cause confusion, mistake, and deception.” Under Amour said that it has been using its “I will” phrase on hundreds of products, packaging and various types of marketing since as early as 1998.
