I think the problem is that you sold an idea that can easily be copied rather than a product. Perhaps an NDA might be the legislative path to take - but sometimes there is another approach: There is a story, which may be an urban legend, but it exemplifies this story nicely: An Optimizations Research (OR) company tries to sell a product that can do crew scheduling for a airlines company. To show its power, they presented an optimized schedule where several million dollars could be saved, compared to their current models. The OR company was declined, but the airline took the data and implemented it. What they did not know, was that the data presented were poisoned. Normally, when optimizing, you also account for the robustness of the model, so emergencies does not bring the whole system down. Being smart, the OR company had removed the robustness constraints, which severely hit the airline. So the bottom line is: Try to poison the sales pitch. Know that you keep out something which is crucial to the solution, but does not impede the impressiveness. Make it into a game: If you choose us, you get to see the rest of the hand, what you don't know is if it is a royal flush or 4 of a kind :)
