"Hi Bruce. Thank you for the great article. In the specific instance of an individual creating a unique dietary supplement formula together with a unique name of said supplement, and having the supplement name trademarked and the formula potentially patented (or in process for patent), and also in the unique circumstance that an already well established supplement company would take interest in partnering by manufacturing and selling said product on their label, what percentage of the net profit of each bottle sold would be reasonable to ask for? In this scenario, there would be no up-front cash or equity stake requested. Let’s just say for the sake of the question that it would only be a set percentage/split which would continue indefinitely as long as the product was still being manufactured and sold by that company."
