Selling an invention without a patent can be challenging but it can be done. Here are some steps on how to go about doing that.

First, apply for a provisional patent from the United States Patent office.  This step is much simpler and than obtaining a full patent.  It also provides you the same legal protection for up to 12 months. 

Second, maintain an inventor’s logbook, which is a detailed diary that documents all the steps you plan on taking to develop your idea or invention.  Always include the date with each entry you make.  This helps show that you developed the idea yourself.  This is necessary if someone else files a patent for the same idea, you can show that you were the first person who invented the product.

Third, you should approach companies in your field that do not already sell a similar product about licensing. Contact marketing managers that are in your target companies and talk to them about your idea

Fourth, you could use an intermediary firm. These companies are “middlemen” to license products to corporations in exchange for part of the license or a flat fee.  They often have good insider knowledge and contacts.  You should also network with other inventors for contacts. 

You should also attend state and national invention conventions. These shows bring together inventors and corporations for products to invest in and develop. Licensing companies also attend these conventions and they do not expect you to have a patent in place.  Another way to sell your idea without a full patent is to license your patent.  These licensing companies are often looking for profitable ideas that generate sales so you could license your idea to these companies if you want to start earning money.    

Also, if your idea is an invention that can be put to use, you might be able to sell it directly.  There are submission companies that will either provide services that help you sell your idea or allow you to sell the product directly to consumers over the internet. You will have to first find the submission company you want to work with.  There are multiple services that these companies offer that you can take advantage of, including graphic illustrations, press release development and publication lists that include information about where you can sell your idea.  

Seek an attorney’s advice if you have any questions about selling your idea without a patent.
