Why don't you just call and ask one of their management team. Chances are Dr Victor reads this board from time to time but I would just call and ask. Its not that large of a company yet that a call would go unanswered. As I understand it, they were the ones to develop this process itself so I doubt they would leave out the patent step.
Then again this last PR release is sort of a direct challenge to others in the arena with less efficient or effective means of collection so one would assume the counter move will be to challenge validity or find fault in the claims.
If it works it would be great. It's just that there are no published case studies I can find, and I can't find the patents. I'm not saying that it does not work, the evidence is just a bit thin right now.
