If you know that you have found out something that others have not then you have to first patent your invention before you try to sell it. Without patenting your invention if you try to sell it, you might lose it and chances are that somebody might steal your invention by patenting that in their name or company. So it is necessary to learn about patenting before you sell your invention. A patent gives you the right to possess that invention and it is possible to sue any person or company who is using your invention without getting approval from you in the form of license. Once patented you have give license to others to use your invention to create the necessary products or process or anything else. By this way you can sell your invention in the form of licenses.
Check out the website of the U. S. Patent and Trademark Office (www.uspto.gov) for more information on the types of patenting and the different application forms available for patenting. First you might require filing a provisional patent application and then a regular patent application within one year of filing the provisional application.
