2009, Ozzy Osbourne was suing the band's guitarist Tony Iommi over royalty payments. The 60-year-old had accused Iommi of falsely claiming to have sole rights to the band's name which has cost him royalties from merchandise sales. Osbourne was seeking unspecified damages, lost profits and a declaration he is a half-owner of the trademark. Iommi claims Osbourne legally relinquished rights to the band's name in the 1980s. Osbourne said he believed all four original members of the band should share Black Sabbath's name equally.
