A London company owned by former members of English rock band The Beatles and their successors has lawyered up in South Florida. They’re gearing to fight a group of defendants who have allegedly earned substantial profits by selling products featuring trademarked phrases “The Beatles,” “Beatles” and “Yellow Submarine.”

Plaintiff Apple Corps Ltd. is owned by Ringo Starr, Paul McCartney and the estates of John Lennon and George Harrison. It was founded in 1968 as a business venture that combined music, films, fashion and electronics, and now continues to hold licensing rights for the band’s brand and music.
