The eight-person panel resumed deliberations Friday morning, one day after hearing closing arguments. Gaye's children are suing Robin Thicke, Pharrell Williams and the rapper T.I., alleging their song copies Gaye's 1977 hit "Got to Give It Up."
Jurors heard from Thicke and Pharrell, who denied they copied Gaye's song. Much of the trial focused on detailed comparisons of the two songs.
An attorney for the Gaye family told jurors they could award millions of dollars in damages if they determine "Blurred Lines" copied the earlier hit.
"Blurred Lines" was 2013's biggest hit and earned Williams and Thicke more than $5 million apiece.
