The Japanese games firm, which publishes the Guitar Freaks series and is also developing a music-based game with drums entitled Rock Revolution, claims Rock Band infringes its patents relating to musical instruments and a 'musical-rhythm-matching game'.
According to Bloomberg, Konami is seeking cash compensation and an order to block the use of its inventions.
Rock Band has proved such a success for publisher Electronic Arts that the firm has already announced plans for a sequel this September.
