If we severed our relationship with TPL, the MMP would not be "worthless", as, per patent law, either patent owner could pursue infringers independently (keeping all the fruits) - and TPL is in a much better position (with their legal staff) to do that.
If the Co-ownership of the patents was split... Every potential licensee would play PTSC against TPL and vice versa.. garnering the lowest possible price for patent licensing ('but PTSC said they'd license it for this price...')... basically, IMO, rendering the patents worthless. BIKN..
