Jay-Z's company Roc Nation is being sued by Volcom for trademark infringement over its diamond-shaped logo.
Volcom, a Costa Mesa-based clothing manufacturer that specialized in streetwear and accessories, is claiming that Roc Nation’s logo bears too close a resemblance to its own diamond symbol, a logo they've used since 1991. In the details of the lawsuit, Volcom said it has been asking Roc Nation to cease using the logo since it debuted in 2009, but has been completely ignored.
The lawsuit states: "While Roc Nation appears to have initially used the diamond only in combination with the words 'Roc Nation' it is now using the diamond log on its own, causing a likelihood of confusion among consumers." The logo is appearing on Roc Nation-branded headphones, clothing and records.
