This has been going on a while as back in August Robin Thicke and Pharrell filed a preemptive lawsuit against Marvin Gaye's family telling them to back down about all this copyright infringement claims.

It is all going down now.

The suit also cites several interviews in which Thicke credits Marvin Gaye as a great inspiration.
The family is also suing EMI, which works for both sides, for 'failing to protect Gaye's songs' and for bullying them for taking legal action.
