I think there could be a case for the negotiations to end rather quickly...
Think about it-
Cooper wants what we think is a specific tech that epgl has the rights to. They could negotiate this pretty easily. Simply determine a fair market value...what is fair market value? In basic terms, what a willing seller is prepared to accept and what a buyer is prepared to pay! The asset is the technology as I understand it. There's no tangible property, assets (other than the tech),assets/liabilities, etc.
I don't know, I may be reducing this to the basics, but they are negotiating one thing-the ability to use the technology that epgl possesses.
Wishful thinking, but big business can get things done quickly if both sides want it done quickly! imo
