Robin Thicke and Pharrell Williams will have to pay a little less to the family of Marvin Gaye after a US judge reduced the level of damages by $2 million in their copyright case over the hit Blurred Lines.

Back in March $7.4m was awarded to the estate of Marvin Gaye for copyright infringement, due to the song's similarities with Gaye's 1977 hit Got to Give It Up.

Thicke and Williams had appealed the verdict, seeking a new trial, but US District Judge John A Kronstadt rejected the request for a new trial, ruling on Tuesday that the pair should pay $5.3m because the original ruling was not supported by appropriate evidence.

As a result, the damages payments have been cut from $4m to $3.2m, and Williams will now pay $358,000 from the $1.6m in profits he was originally ordered to pay.

But the new ruling also saw long term benefits for the Gaye estate as it was awarded 50% of future songwriting and publishing revenues earned by Blurred Lines.
