Patents are issued by the United States Patent and Trademark Office Patents provide limited protection by keeping others from duplicating an invention with the intent of making a profit. While there are three different classifications for patents – utility, plant and design – a new shoe would most likely be protected by a design patent. Once issued, the patent would last for 14 years.
Before Applying for a Patent
As you develop your idea for a new shoe design, it's important to document everything you do, including drawings and notes of the process, and keep it in a safe place. If you are constructing a prototype of the shoe, take photos of that process too. Date and sign all documentation and have two witnesses sign them. If you are uncertain about any part of the patent process, you may want to consider hiring a lawyer with experience helping clients obtain patents.
Applying for a patent can be expensive, so you should be relatively certain that you will be able to make money from your shoe design – such as producing and selling it yourself or selling the design to a shoe manufacturer. Once you are certain there is a commercial value for your new shoe design, do a thorough patent search at uspto.gov, the United States Trademark and Patent Office website, to be certain no one else has already developed and patented the same shoe already. While there is a search fee when you apply for a patent, searching the USPTO database yourself beforehand is free. If you plan to file patents in other countries, you should research patents in those countries too.
