Former "Patridge Family" star David Cassidy is looking to Sony for money he says the studio owes him. TMZ.com describes a lawsuit the actor has filed against the entertainment giant, claiming the studio used his image on merchandising for "The Partridge Family" TV show without his permission for more than four decades.  Cassidy claims he signed a contract with the show's production company in 1971 that guaranteed him 15 percent of net merchandise revenues for the use of his image or likeness.

To date, he says he's received about five-thousand-dollars, a drop in the bucket compared to the almost 500-million-dollars he says Sony has made from "Partridge"-related lunch boxes, comic books, board games and other merchandising ventures.  Cassidy is suing Sony for breach of contract and fraud.  TMZ says he's seeking millions-of-dollars in damages.
