The first dispute began in 1978 with Apple Corps Ltd`s complaint against computer manufacturer Apple Computer for trademark infringement. These disputes continued between 1978 and 2006. Apple Corps Ltd. filed another breach of contract complaint in which apple Computer Inc. had violated an earlier trademark agreement by using the Apple logo for its iTunes Music Store logo. On May 8, 2006, the High Court of Justice ruled in favour of Apple Computer. Another notable proof is the management contract signed by John, Paul, George and Pete as members of the Beatles. Brian had not signed the contract. If Pete Best were just a “leased hand,” the contract would not have included it.
The four Beatles presented themselves as a group, in partnership. For a band known for songs like “All You Need is Love,” “Revolution” and “Let It Be,” it may be surprising that the band`s separation was fierce, company-based and withdrawn. The end of the band was not marked by four long-haired men who separated, guitars in hand. Instead, Paul McCartney filed a complaint on December 31, 1970 against the dissolution of the Beatles partnership. This followed John Lennon`s private announcement to leave the band. Due to numerous disputes, the dissolution of the partnership was not completed until the mid-1970s. This was only the beginning of the Beatles-related legal affairs and a study of some of these issues reads like a law course in entertainment, intellectual property and corporate law. Lennon didn`t care when the $1.5 million wind from Live Peace in Toronto entered the General Kitty; Harrison was happy to share royalties on his best-selling Box All Things Must Pass with his former bandmates. But McCartney has a different opinion.
Perhaps he was simply willing to bet on himself because he believed that his own career in an ongoing partnership with Lennon, Harrison and Starr was worth more than a quarter, and his secret purchase of Northern Songs shares indicated that he had been maintaining himself as a separate agent in Serden for some time. But one thing was certain: Paul did not trust Allen Klein and did not want to have him anywhere near his work, his fortune or his money. That`s what he did in the mocking interview of mcCartney`s copies. Since Klein no longer managed Apple, the group`s four former colleagues were able to work cooperatively to reach an agreement. This document, known as “The Beatles Agreement”, was signed by the Four in December 1974.  Photographer Bob Gruen recalled Lennon`s fun about the length and complexity of the comparison document and said, “He told me that the initial agreement between Klein and the Beatles was two or three paragraphs on a single sheet of paper.
