By the way, in the United States copyright is owned by the author of the work unless there is a written contract assigning it to someone else. The only real exception to this is an employee can assign copyright to their employer by mere verbal agreement. Since you were a contractor they don't have the copyright unless you actually have a written contract assigning it to them.

This is exactly the contract that has caused the issue. I asked for the agreed fee for my IP under the terms of the contract.
