As President of a local inventors group I can’t tell you how many inventors I meet who have spent big bucks to procure a patent but never built a prototype. So they have no idea if the invention really works. Others who have a garage full of product, just collecting dust because they never tested the market before hand. However, most successful inventors and product development companies that I know, start off with a Proof of Concept Analysis BEFORE they start spending money. So if they do it, why not you?
