hello,
was wondering if someone could direct me in the right direction. I have a car innovation that may possibly revolutionize the whole car industry if implimented. I contaced several companies that look for new inventions and ideas and I have decided not to liscense my idea with them. If I wanted to pusue this idea myself, how would I go about doing it? Are there automotive conventions, or a group of people to which I can express this idea? I don't want to target a specific brand, but rather target the whole automotive industry. If someone could help, I would greatly appreciate it.
