Guitar Hero Out Of Tune As Lawsuits Issued

One of the worlds most popular video games “Guitar Hero” is in strife with Gibson Guitar filing yet another patent infringement lawsuit against Viacom who own the MTV networks and Harmonix. Several weeks ago they also took action against Electronic Arts.

The lawsuit, according to Reuters was filed in the US Federal District Court in Tennessee and relates to the same patent involved in another suit Gibson filed earlier against various retailers, the Tennessee-based guitar maker said in a statement.

The “Guitar Hero” series has sold more than 14 million units in North America and raked in more than $1 billion since its 2005 debut.

Gibson said the games, in which players use a guitar-shaped controller in time with notes on a television screen, violate a 1999 patent for technology to simulate a musical performance.

Harmonix developed the first “Guitar Hero” game and was later bought by MTV. Electronic Arts and another company, Activision Inc, as well as several retailers, either develop, distribute or sell one or several of the games in the “Guitar Hero” series.

“This lawsuit is completely without merit and we intend to defend it vigorously,” Harmonix said in a statement.

A spokesperson for Electronic Arts could not be reached for comment.

Earlier this month, Activision filed a preemptive suit against Gibson, which had complained that the games infringe upon one of its patents.
