Bob Marley Lawsuit -- Family Sues Bro for Fishy Use of Bob's Name

Bob Marley's widow is smoking mad over a relative pimping out the family name to sell everything from concerts to fish, poultry, energy drinks and booze -- and she's suing to stop him.

Rita Marley and nine of Bob's kids filed a federal lawsuit against Richard Booker -- Bob's bro from another father ... for trademark infringement and unauthorized use of Marley's likeness.

According to the suit, Booker's been real busy -- registering the trademark "Mama Marley" to sell ... among other things ... fish, fish and chips, fish cakes, fish croquettes, fish fillets, fish mousse, and fish sausages. Yes, Bob loved him some fish.

In addition, the suit claims Booker is using Marley's name and image to market an annual concert in Miami, known as the 9 Mile Music Festival. For those not in the know ... 9 Mile is the Jamaican village where Bob was born and buried.

Bob's family says they have the rights to all things Marley and want all of Booker's profits. They also want a judge to order Booker to stop all future use of the name.
