Marvin Gaye's family is making some headway with their ongoing legal battle over Robin Thicke’s song 'Blurred Lines.' The Gaye family has reached a settlement with EMI April, owned by Sony/ATV, which oversees their father’s music catalog.

The Gaye children -- Frankie Gaye and Nona Gaye -- allege that 'Blurred Lines' is a copy of their father’s song 'Got to Give It Up.' The duo is accusing Sony/ATV of breaching its contract by failing to protect Gaye’s music.

According to The Hollywood Reporter, the Gaye family accused the music publisher of allegedly granting the rights to 'Blurred Lines' and not informing them so they didn’t get in the way of the song's ongoing success.

The terms of the settlement with Sony/ATV have not been disclosed.

However, this settlement doesn’t put Thicke in the clear. The copyright-infringement lawsuit between Gaye's children and the crooner could potentially go to trial.

In addition, the 'Give It 2 U' singer has to battle a separate countersuit filed by Marvin Gaye III, the late singer's eldest adopted son, who claims that Thicke habitually steals from his father's catalog. He also believes that 'Blurred Lines' is a rip-off of the Marvin Gaye song, 'Got to Give It Up.'

So the legal battle rages on.
