Robin Thicke Marvin Gaye lawsuit has been filed by the "Blurred Lines" singer to Gaye's family seeking to preempt legal claims that Blurred Lines borrows too aggressively from late soul legend Marvin Gaye and the group Funkadelic.

Attorney for Robin Thicke and the song's collaborators, Pharrell Williams and T.I., filed a lawsuit in Los Angeles on Thursday asking a judge to determine their song does not copy songs composed by Marvin Gaye and George Clinton.

Representatives of the owners (Gaye family) of copyrights to Marvin Gaye's song "Got to Give It Up" and Clinton's song "Sexy Ways" have warned Robin Thicke that he and his collaborators have used elements of the songs in "Blurred Lines."

"Plaintiffs, who have the utmost respect for and admiration of Marvin Gaye, Funkadelic, and their musical legacies, reluctantly file this action in the face of multiple adverse claims from alleged successors in interest to those artists," the Thicke suit states. "Defendants continue to insist that plaintiffs' massively successful composition, Blurred Lines, copies 'their' compositions." Named as defendants are members of Gaye's family and a company called Bridgeport Music, which owns some of Funkadelic's songs.

The Gaye family, according to the suit, recently "notified plaintiffs that, if plaintiffs do not pay a monetary settlement of the Gayes' claim, the Gayes intend to initiate litigation for copyright infringement against plaintiffs."

The album, titled "Blurred Lines," debuted at #1 on both the UK & Scottish Albums Charts. The song has become one of the hits of the summer. "Blurred Lines" peaked at number one in 14 countries including the United Kingdom, Australia, Republic of Ireland, France, Germany, Austria, Italy, Luxembourg, Switzerland, Canada, New Zealand and the United States, becoming Thicke's highest charting song in all of these countries.

In an interview with GQ, Thicke explained: "Pharrell and I were in the studio and [...] I was like, 'Damn, we should make something like that ["Got to Give It Up"], something with that groove.' Then he started playing a little something and we literally wrote the song in about half an hour and recorded it. Him and I would go back and forth where I'd sing a line and he'd be like, 'Hey, hey, hey!' We started acting like we were two old men on a porch hollering at girls like, 'Hey, where you going, girl? Come over here!'" after hearing Gaye's song of "Got to Give it Up."
