A trial in 2015 will settle a dispute over whether 'Blurred Lines' plagiarised elements of Marvin Gaye's 'Got to Give It Up'.

A federal judge in the US, John Kronstadt, has denied a request from Robin Thicke and Pharrell Williams for the claims to be dropped, which means the dispute will head to a celebrity trial in Los Angeles, which is expected to begin on February 10, 2015.

The judge ordered that it will now be a jury's decision to determine the case's outcome, writing: ''Genuine issues of material fact are present as to the extrinsic similarity of the works. The intrinsic similarity of the works is a jury question.''

Charges were filed last November by the family of the late Motown legend Marvin Gaye, against the writers of the 2013 hit - which has sold over 10 million copies worldwide - which claimed that the track copied parts of the 1976 song 'Got to Give It Up'.

Judge John, from the US District Court for Central California, said: ''Defendants have made a sufficient showing that elements of Blurred Lines may be substantially similar to protected, original elements of 'Got to Give It Up'.''
