I remember when kids would literally nearly stampede each other in order to get their hands on a die-cut Volcom sticker at High Cascade Snowboard Camp during the beloved product tosses.  Now, Volcom is alleging that others want a piece of their iconic stone. Volcom filed suit against Jay-Z’s Roc Nation on March 29th in the Central District of California alleging various trademark and unfair competition claims. Additionally, Volcom claims that their signature stone, in use since 1991, has become well known outside of the brand’s “traditional markets of skate, surf and snowboard enthusiasts, and the music/entertainment industry ” and that “Volcom’s stone mark has become a famous mark.” The main item at issue in this case are Roc Nation headphones that display an inverted stone-shaped logo.  Likelihood of confusion?
