Rock band No Doubt sued Activision in 2009 over how their members’ digital likenesses could be used with songs other than their own. They were also not fond of how avatars of other famous musicians could front their songs.
No Doubt claimed to have no knowledge that Activision planned to make that possible and that Activision did not ask permission. This is similar to the claim that Courtney Love had with Activision about using the image of her late husband, Kurt Cobain’s avatar in Guitar Hero 5.
According to a report by the Associated Press, Activision tried to have the case dismissed; Superior Court Judge Ramona See stated that there seems to be a genuine dispute that a jury should consider.
