Product upgrades

[gillikin]

If I have an idea to apply to an existing product - is it legal to collect from more than one company on my idea? Can I submit my idea to multiple companies that produce the same product or if the first company buys my idea, is it void to everyone else? I live in Michigan, the Company I am mailing is located in Ohio.

If you sell an exclusive, you give up the right to license it to others. If not, you don't. The buyer would negotiate for what it wants.
