The bickering Teutuls -- Paul, Paul Jr. and Mike -- of TV's "American Chopper," have sued a company for infringing on their fame.

The trio, appearing as the Orange County Choppers, accuse Goen Technologies of illegally capitalizing on their stardom with the Discovery Channel's cult favorite, "Celebrity Justice" said.

The Teutuls said the problem started when they custom-made a bike featured on an "American Chopper" episode for Goen, the company behind Trim Spa, the weight loss product endorsed by Anna Nicole Smith.

The Teutuls say the bike soon turned up on Goen T-shirts endorsing Trim Spa. The Teutuls say Goen also used their OCC logo on the shirts without their permission. A Goen spokesman said there is a contractual agreement covering the situation.
