Listen at the 25 minute mark..Ann the interviewer asks a question that is.
"Do you see any Pharmaceutical cos that will license your patents in the near future?"
Charles answers--
"We hope..we have over the years..even as we speak, we have always been open to Big Pharma, they have always encouraged us, they have always said..when you get to a certain level that we agree with what you are doing that we will be interested."
Tells me that patents are there NOW to be licensed.
