Guitar Apprentice, a company that provides virtual guitar tutorials to aspiring musicians, has filed a lawsuit against Ubisoft, claiming the company has violated one of its patents with its recent instructional music game, Rocksmith
Patent Arcade reports
that Guitar Apprentice claims ownership of a patent for a "progressive musical instruction" system that teaches users to play an instrument via "audio signals corresponding to a predetermined musical performance."
and Guitar Apprentice use similar interfaces to teach users to play guitar -- the most apparent difference being that Rocksmith
incorporates interactive elements via the Xbox 360, PlayStation 3, or PC, while Guitar Apprentice uses pre-set video tutorials on PC or DVD.
Prior to Rocksmith
's release in October 2011, Ubisoft said
the product drew inspiration from GameTank's Guitar Rising
, an unreleased program that explored the basic concepts of interactive music instruction.
