Moska, everything we have available historically would indicate that a falling out between POET and DR Taylor seems to have occured. Animosity? No, it's not personal, it's just business....
The issuing of patents is about money and future revenue from that idea. There is little or no relationship between the names on a patent and any notion of positive relationships. Poet and Dr Taylor stand to aquire material gains should the issue at patent be involved in a profitable product.
If in doubt, follow the money.
IMO, of course
