In my view, the License Agreement was flawed from the beginning by creating a conflict of interest between Rossi and IH. The main conflict arises from Section 13.4 (“After Acquired/Developed Assets, Intellectual Property Rights”), which stipulates, in the 1st half, that any refinements or upgrades that Rossi makes to the E-Cat are also covered under the agreement, and, in the 2nd half, that after the agreement, both parties can do their own research and “all inventions, discoveries, concepts, ideas, information and anything else that the Company [IH], its sublicensees, or any of their affiliates, makes or develops which relate to the E-Cat IP or are useful in the business….[etc etc]…shall remain the property of the Company (or such sublicensee or affiliate if so agreed by the Company)”.
Now it depends on very specific interpretation of law, whether A. Rossi was right, when he attacked the IH for issuing his own patent applications BEFORE paying the COMPLETE license fee or not. Try to imagine, you're in A. Rossi position, who just sold successfully his technology to first customer, who has been willing to pay for it under these circumstances. But subsequently you just found another modification of technology (Quark-X), which is clearly superior to former one and which would immediately make this older technology obsolete - so you would want to keep this new technology for yourself.
What will you do? First of all, you'll attempt for doubting the existing license transfer by first minute delay of payment, which your competitor (IH) will commit - willingly or by accident.
