It looks like the catalyst is licensed from UoS and is 100% theirs (UoS), as well as being patent issued. From all the pages I looked through on that link, and from what I read on what the ILO does at UoS, they do NOT license out any technology without it having a patent. Basically it looks like CABN is bringing the UoS technology to commercialization.
I couldn't find any of the payment terms, or any other licensing terms for this deal in detail. There is also a page on the above link that answers your last question. Based on these articles, CABN still had a problem with the carbon deposits.
