Finding a large company to license your invention is often the route chosen by inventors. Although this route appears simple at first, it is typically very difficult to find a company interested in licensing an invention. Those with the highest chance of success will be those who are recognized experts in their field, and/or those who have a pre-existing relationship with the prospective licensee. Be careful how you present your idea to prospective licensees. Many companies have “idea submission web pages. However, by clicking “submit,” you agree that they are free to use the idea unless it is the subject of an issued patent, making the use of these pages a bad idea. Even without using these pages, you will often be asked to sign an agreement. Some of these agreements are reasonable, some are unreasonable, and all will protect the prospective licensee from liability for using anything that their own employees develop independently. Any document you are asked to sign should be reviewed by your attorney before you sign it. I generally do not recommend the use of “invention promotion” companies. You understand the need for your invention better than anyone else, making you the best person to sell your invention. If you choose to work with these companies, investigate their track record carefully before proceeding.
