From what I have seen from previous discussion. YA own`s the patents as collateral for the loans they issued to NEOM. However, as part of their ongoing business, NEOM can license that patents, but not sell them as they are pledged to YA due to the debt. Best way (cheapest) for the Dr to get the patents, is buy the NEOM debt from YA, as NEOM will not have enough cash from operations to pay off the July maturity.
