Justin Bieber's legal battle with game makers

Pop superstar Justin Bieber has stepped up his legal battle with the makers of a game which pokes fun at him, filing new court documents in a bid to halt sales.

The Baby hitmaker's attorneys recently sent a cease-and-desist letter to bosses at games company RC3, alleging their Joustin' Beaver cell phone application, which features a Bieber-styled beaver, infringes the singer's trademarks.

They threatened to sue unless the game is removed from sale on the iTunes website, but RC3 executives refused and subsequently filed a preemptive lawsuit against Bieber, asking a court to declare they are not breaking the law by mocking the teenage star.

However, Bieber's legal team has now hit back and filed new court documents last week (ends27May12) in a bid to have the game removed from sale.

The legal papers state bosses at the company filed their lawsuit in Florida, and since Bieber does not live in the state, their case should be dismissed, according to TMZ.com.
