There are two ways you can exploit your invention:
It is often supposed that the second is the easier option but in many ways it is the more difficult. First you need to find a potential licensee for the invention.

You will need to show that your invention works. Thirdly, you must have something to license. That usually means you have to get a patent (see "How do you protection your invention?"). Finally, you have to satisfy the potential licensee that it can make money from your invention.
