A copyright infringement lawsuit surrounding Jay Z's hit song Big Pimpin' is set to rumble on into 2014 after a California judge refused to dismiss the six-year case. The rapper was slapped with legal action in 2007 from Osama Ahmed Fahmy, amid allegations the 2000 track violates the plaintiff's rights to his uncle Baligh Hamdy's composition Khosara, Khosara, which was released in 1957. Jay-Z's record label bosses at EMI argued that Big Pimpin' was protected under a licensing agreement they had made with bosses at Egyptian firm Sout El Phan, which previously co-owned the copyright to Khosara, Khosara, prompting a Los Angeles judge to issue a summary judgement in their favour in 2011. However, that deal expired in 2006, and now U.S. District Judge Christina Snyder has granted Fahmy until March (14) to conduct further research into case, to determine whether the defendants had wilfully broken copyright law after the licensing period had ended. If he is able to prove the violations, Jay Z and his label bosses will be liable for copyright infringement, according to The Hollywood Reporter.
