How do you know there's not? If there was only some sort of legally binding arbitration system we could find out.
The code is the contract! /s
The wording in the article is kind of vague "parallel technology partnership agreement". I have no idea if "parallel" means that the 2 contracts are connected or not. Maybe that's what the court is going to determine.
A contract requires something to be exchanged, there is a minimum of one other thing that has to be connected to this. (I.e. payment for the option)
