Rapper Jay-Z's company Roc Nation is being sued for trademark infringement by the modern lifestyle brand Volcom.

COURT DOCUMENTS: Jay-Z Vs. Volcom Lawsuit

In court documents obtained by RadarOnline.com, Volcom filed the lawsuit with the Central District of California on Tuesday and is demanding a jury trial.

According to Volcom, they began using the trademark "stone" on their products in 1991 and "the distinctive stone mark, which resembles an inverted diamond, was different from, intended to be different from, and remains different from, any mark used in the industry."

"Despite its awareness of Volcom's stone mark, in approximately 2009, Roc Nation began using a very similar inverted diamond logo," the documents state.

COURT DOCUMENTS: Volcom Lawsuit

"Roc Nation was previously notified that its use of the inverted diamond logo infringed Volcom's stone mark.

"However, Roc Nation refused to cease its infringing use of the inverted diamond. Its infringement of Volcom's stone mark is thus willful."
