Patents do have a limited life. Let's get on with it please...and quite talking in terms of which decade they are going to monetize this. I do hear Dr Lebby talking in terms of extending their patent moat. But you do have to keep an eye on the ones that expire. A public company needs to denonstrate they can turn a science project into revenue. Kindly put the business hat on for the sake of the investors. And by the way - you are amazing and keep fighting the good fight!
