Gotcha, sorry didn't understand that. In the code that I've seen so far, there has been no license. Everything was handled in the contract. "Everything you touch is owned by us, all code you write for this project is owned by us, and if you leak it or show it to a third parry without our consent, we have you by the balls". Pretty much been my experience.
Sometimes there's been a short header in every file "This code is copyrighted and owned by $Company".
