Call the Invention Submission Corporation. They will help you patten your idea, but you have to share royalties with them.
you really have to access your invention/idea, if it s going make a profit when you patten it, and how serious you are about commercializing it. There are people who sponsor these kind of entrepreneurship, they are the Venture Capitalists. However, they will take a big chunk of your business, normally 50%. Sometimes the banks sponsor it too, but you need a solid business plan to convince them. Keeping the patten every year is very expensive, unless your invention can generate a constant stream of cash flow, please don t do it, it s a very risky business.
You have the answer....someone rich or a rich company will have to agree to finance the project. YOu ll have to convince them it will be worth their investment.
