Max Warren performs under the stage name Maxamillion. He says Khalifa's chart-topper "Black and Yellow" was lifted from his own song "Pink N Yellow."
Warren says he copyrighted "Pink N Yellow" in 2008 and Khalifa copyrighted "Black and Yellow" in 2011.
The copyright infringement lawsuit was filed in federal court in Philadelphia and seeks at least $2.3 million in damages. It names Khalifa, whose real name is Cameron Jibril Thomaz, two other songwriters and several record companies and music publishers.
Warren's lawyer declined to comment Thursday. A spokesman for Khalifa at Atlantic Records didn't immediately respond to an email seeking comment.
