I'll just throw in my 2 cents. I think that this structure is being setup smartly for current and future possibilities. To start the 2 subs under the parent corp signed agreements to be able to license out the technology. So now the company can go license this now. If in the future there is interest in 1 product it can be sold off easily without having to unwind agreements and keep the other product(s) intact. Think of it like avoiding "Co-mingling".
It seems to me that Charles already knows the outcome of the testing and is now having some of the leading specialist in this field document the findings so there can be no mistake that this technology is correct and can be licensed. That's why he formed these subsidiaries even before the results are documented. He is really setting this company up for $$$ SUCCESS $$$
Maybe it is so that they can charge twice the amount or to offer a bundle? Maybe each patent can be used for separate types of applications or medical “cocktails “.? Or for tax reasons. Probably tax reasons.
