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 Nike, based in Portland, Ore., has started an advertising campaign using phrases such as “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.
Nike spokeswoman Mary Remuzzi declined to comment.
Under Armour is requesting a permanent injunction to bar Nike from using the “I will” phrase. It is also wants Nike to destroy all products, packaging and signs that use the tagline.
