Search the USPTO database for existing patents. The USPTO online database allows you to search through existing food patents using a number of search parameters, such as patent number, date of issue and product descriptions. Prior to filing a patent application, you must insure that your food product is unique, meaning that a patent doesn’t exist for the same product.
Prepare the utility patent application transmittal form. When filling out the transmittal form on Form PTO/SB/05, you must include your full name, the title of the food product you seek patent protection for and a list of all documents you are submitting with the application.
Draft a written description of the food product. Your description must include the information for each of the 13 headings the USPTO requires under the specifications section in its Guide to Filing a Utility Patent Application. Write “not applicable” under the headings that aren’t relevant to your food product.
Draw pictures of the food product in black and white. Multiple drawings, each depicting a different angle or view of the food product, are necessary if you’re unable to include all distinguishing characteristics in a single drawing. Each view must be appear on a separate page.
Fill out an oath or declaration form. The USPTO provides standard oath and declaration forms on its website for download. Regardless of the form you choose, you must report the food product’s title, your address and country of citizenship and the names of all inventors on it.
Prepare a fee transmittal form. Obtain Form PTO/SB/17 from the USPTO website and follow the instructions to calculate the appropriate patent application fee. The USPTO requires that you make payment by check or credit card at the time of filing your patent application.
File your food product patent application. You can submit all patent application materials electronically using the USPTO’s EFS-Web service. The USPTO encourages electronic applications and increases the fee if you decide to file on paper. If you prefer to file by mail, send all your paperwork to the address listed on the application.
