Konami and Viacom Settle Patent Fight Over Music-Video Games

Konami Corp. and Viacom Inc.’s Harmonix studio settled a patent dispute over music-video games including “Rock Band,” according to court filings.

Terms of the agreement weren’t disclosed. The companies said in a filing yesterday in federal court in Tyler, Texas, that they agreed to dismiss “all claims and counterclaims” in the suit, filed by Konami in 2008. Notice the companies agreed to drop a Viacom suit against Konami was filed today in federal court in Boston.

Konami, based in Tokyo, makes “Rock Revolution,” which simulates playing popular music and Harmonix, owned by New York- based Viacom, makes the competing “Rock Band.” Each suit claimed infringement of patents related to game controllers that simulate musical instruments.

The Konami case is Konami Digital Entertainment Co. v. Harmonix Music Systems Inc., 08cv286, U.S. District Court, Eastern District of Texas (Tyler). The Viacom case is Harmonix Music Systems Inc. v. Konami Digital Entertainment Co., 09cv10206, U.S. District Court, District of Massachusetts (Boston).
