Dr. Dre Sued By Lucasfilm: "One day after taking legal aim at Napster, Dr. Dre is now the target of a high-profile legal salvo himself.... Lucasfilm's suit, which seeks unspecified damages, hinges on Dre's use of something called the "THX Deep Note," a sound trademarked by Lucas' company. According to Lucasfilm, the sound is the first ever to be trademarked; it should be familiar to moviegoers as the sound that accompanies the THX logo before films screened in theaters with THX sound systems."
