Jay-Z and Iconix Brand Group have reportedly been slapped with a   lawsuit for using the 'I Will Not Lose' slogan in a Rocawear campaign.

According to Allhiphop, the Brooklyn rapper and Iconix Brand Group were sued yesterday (September 25) by a company called I Will Not Lose, LLC which claims they trademarked the slogan first.

Jay-Z sold Rocawear's rights to Iconix Brand Group for $204 million last year and they used the 'I Will Not Lose' slogan in a campaign which featured Jay-Z, Chris Brown and Three Six Mafia.

Reggie Tucker, the CEO of I Will Not Lose,LLC (www.iwillnotlose.net), claims that he repeatedly requested Jay-Z and Iconix to stop using the slogan but he was ignored.

Tucker filed the lawsuit in Georgia Northern District Court last week and is seeking unspecified damages.
