THE Beatles' record label Apple Corps has clashed in London's High Court with Apple Computer in the latest of a long-running series of battles over the companies' names. Apple Corps has accused Apple Computer of breaching an agreement the two firms reached 15 years ago (91) by selling music. The pair have been tussling since the technology giant was formed in 1976. They agreed to share the name Apple and the apple logo in 1981, but landed back in court in 1989 as Apple Computer became more involved in entertainment. In 1991 the computer firm - founded by STEVE JOBS - was forced to pay $26 million (GBP15.3 million) and was barred from entering the music business. The two Apples clashed again when the iPod mp3 player was released by Apple Computer in 2001. Now Apple Corps, owned by Sir Paul McCartney, Ringo Starr and the families of George Harrison and John Lennon, claims that, by selling music from its i-Tunes website, Apple is breaching the 1991 agreement. Solicitor NEIL VOS, representing Apple Corps, says, "(Apple) Computer was promoting a store at which to buy music, and more particularly, Computer's musical recordings - permanent downloads - with special characteristics. "No objective onlooker could think otherwise."
