Tokyo - Japanese video game developer and publisher Konami has filed suit against Viacom-owned (NYSE: VIA) "Rock Band" game developer Harmonix, alleging the popular music game infringes on several of Konami's patents, Bloomberg reported.

Konami has released its own line of music-themed games, including "Dance Dance Revolution" and "Karaoke Revolution," and plans to put out a title similar to "Rock Band" called "Rock Revolution" later this year.

The Konami lawsuit, filed in federal court in Texas, seeks monetary damages, as well as an injunction against Viacom and Harmonix that would prevent the release of further infringing products.
