Wrestler Diamond Dallas Page is suing rapper Jay-Z and Rocwear and Roc-a-fella Records over use of a ‘diamond cutter’ hand gesture. Diamond Dallas Page v. Shawn Carter p/k/a/ Jay-Z, 2:05-cv-08475-DSF-JWJ (C.D. Cal 2006). Coverage here. Given that the complaint is not available on Pacer, we can’t evaluate some fairly novel elements here, such as the description of the mark, the manner in which defendants used the mark, and how one person using a hand gesture can be confused with another person using a hand gesture.
UPDATE: depictions of the hand gesture here.
