Being secretive made me think about Intellectual Property. I wonder if it is possible to patent a process to "cure "aging", because a patent describes a process with a begin, an end and a result. You can patent a drug, its usefulness is clear, you are ill, you take a drug and then you are in good health. It can be measured with bio markers. In contrast "curing aging" is something different, the result is that you do not age, nothing has changed, what does that mean from an IP point of view?
