Ozzy isn't only fighting in World of Warcraft

Perhaps you've seen the commercial in which Ozzy Osbourne is contesting his "Prince of Darkness" claim against an animated character from World of Warcraft. Well, Ozzy isn't only fighting in second life, but also in first life. In this case, he is fighting against Tony Iommi:

With his former Sabbath band mates Tony Iommi and Geezer Butler touring and recording with Ronnie James Dio (Osbourne's replacement in Black Sabbath when he left the band in 1980) as Heaven and Hell, Ozzy Osbourne is suing Iommi over the rights to the Sabbath moniker....

In a suit filed in the U.S. Trademark and Patent Office, Osbourne's lawyers allege that the guitarist for the heavy metal giants has claimed sole ownership over the Black Sabbath name, one of the most valuable and revered in metal music. Osbourne, who states in the suit his "Signature lead vocals" led to the band's "extraordinary success," citing a dive in their popularity during his 1980 - 1996 separation from the group, is seeking 50 percent ownership of the moniker.
