Ubisoft's forthcoming music title Rocksmith has found itself the target of a patent infringement claim from a company who make guitar tutorial software.
As reported by Patent Arcade, Guitar Apprentice is taking the French publisher to a Tennessee court for allegedly infringing USP 8,119,896, titled "Media system and method of progressive musical instruction."
Its original listing was made back in October 2010, while Rocksmith was unveiled in March 2011.
It's not the first time the game has landed Ubisoft in hot water. UK rock band Rocksmith claimed it owned the trademark on the name last October, with legal wranglings still ongoing.
Discounting any legal pitfalls, the game is currently scheduled to launch in Europe this September, following a muted release in the US last year.
