T.F.
No I haven't. However, there are a lot of vultures out there who will steal your idea in a heartbeat.
Make sure you have yourself covered with trademarks and patents. You need to work with an attorney experienced in this type of law.
My husband does have a few patents because we are in the plastics industry and it involves coming up with specific formulas in order to make specific products... EX: something FDA approved, specific colors, UVA protected, etc. It is a lot of work but worth it in the end.
I wish you the best!
