Rocker Jon Bon Jovi is suing a former employee of his Arena football team Philadelphia Soul, accusing the man of copyright infringement.

The Arena Football League (AFL) team was crowned champions in 2008 and each player was given a special ring to commemorate the occasion. The Bon Jovi frontman and officials at Philadelphia Soul claim ex-sales manager Joe Krause illegally made his own version of the championship rings and sold them on to the public.

In the legal papers, filed in court on Thursday, the team owners allege the design of the ring belongs to them, as well as any use of the team logo. They are suing for damages and demanding all remaining infringing articles be destroyed, reports TMZ.com.

It is the second legal dispute between the two parties in the last few months - Krause filed his own lawsuit against Philadelphia Soul bosses in December, accusing them of failing to pay him almost $125,000 in outstanding wages.
