But I can' t tell you. Seriously, I' m dabbling with a archery invention and I don' t know which way to turn. The idea may not be as revolutionary as the compound bow was, but I feel it can greatly help shooters. I checked around with some patent sites and it looks like it will cost up to $10,000 to get a patent on this thing. Does anyone know of any other options? Ideally, I would like to bring it to an archery company and have them run with the idea. I have built a prototype and it works great. Sorry I can' t say what it is. Thanks for any help.
