The battle over "Blurred Lines" still isn't over.

The family of Marvin Gaye has requested that Robin Thicke, Pharrell and T.I. pay their attorneys' fees and other allowable expenses -- about $3.4 million, according to a document obtained by ABC News.

In paperwork filed by their lawyers, Gaye's children, Nona and Frankie, have asked the singers to pay about $2.67 million in attorney fees and $776,932.71 in non-taxable costs.

"The Copyright Act provides that in an action for copyright infringement, the Court may award 'a reasonable attorneys' fee to the prevailing party as part of the costs,'" they wrote. "An award of fees to Nona and Frankie Gaye will, therefore, further the purposes of the Copyright Act."

Last March, a jury ruled that Robin Thicke and Pharrell Williams copied part of Gaye's song, "Got to Give It Up" for their hit, "Blurred Lines."

As a result, the Gaye family was awarded approximately $7.4 million in damages. According to the Hollywood Reporter, in July, a judge reduced that amount to $5.3 million and rapper T.I., Universal Music Group, Interscope and Star Trak Entertainment were added to the lawsuit.

At the same time, the judge denied the Gayes' bid to remove the song from distribution, but granted their request for ongoing royalties of 50 percent.

According to multiple reports, Thicke and Williams filed an appeal this past December.

They have not yet commented on the most recent filing.
