HARMONIX AND VIACOM V. KONAMI

Harmonix and Viacom have instituted proceedings against Konami. The Plaintiffs who developed Rock Band are claiming that the peripheral for Konami's Rock Revolution violates a patent that they hold for controllers that simulate musical instruments.

This is not the first lawsuit to involve these parties. In an earlier lawsuit, Konami had sued Harmonix. It claimed that Rock Band infringed its patent rights.
