Marvin Gaye's children sue Robin Thicke, Pharrell and T.I. over Blurred Lines A still from the video clip of Robin Thicke's Blurred Lines, which is at the centre of a legal dispute. TWO of Marvin Gaye's children have countersued Robin Thicke and his collaborators on the hit Blurred Lines for copyright infringement. The suit filed in a Los Angeles federal court accuses Thicke and fellow singers Pharrell and T.I. of copying Gaye's hit Got to Give It Up. Nona Marvisa Gaye and Frankie Christian Gaye also accused music company EMI of failing to pursue a copyright infringement claim and trying to intimidate Gaye's children from filing a lawsuit. EMI is owned by Sony Music Entertainment, which didn't immediately return a phone message seeking comment. Thicke asked a federal judge in August to rule that his song didn't copy Got to Give It Up. Thicke's attorney Howard King says the Gayes' decision to sue EMI shows the family doesn't have the authority to pursue claims against his client.
