Monetizing with Licensing
Licensing is an effective way to monetize a invention. After the invention is patented, you can begin approaching businesses that may benefit from your innovation. The licensing terms that you can ask for will depend heavily on the value your invention adds to the product and the overall value of the product.
If you are willing to wait, you can also monetize inventions that you do not actively promote. Great ideas are often adopted and spread virally without the inventors involvement.
