Search the USPTO online database of existing patents to make sure your food idea hasn’t been patented already. You can conduct a basic or advanced search using various keywords at the USPTO website (see Resources). A thorough search using all possible keywords is essential so you don’t waste time and money filing a patent application for a pre-existing food product or recipe.
Evaluate your food idea and make sure it includes a unique recipe or cooking process. Your food idea must be “novel and non-obvious,” meaning it must either result from combining a unique set of ingredients or a unique way of preparing it. For example, making improvements to an apple pie recipe using common ingredients may not be sufficiently novel to warrant a patent.
Prepare the utility patent application documents. The USPTO requires that your complete application package include an application and fee transmittal form, application data sheet, a written specification that outlines all aspects of your food idea, drawings or images of your food product (if including them will strengthen your claims) and an oath or declaration that you are the original inventor. The latter is required only if you are filing a non-provisional patent application. For some of these documentary requirements, the USPTO provides standard forms on its website that you can fill in.
File your patent application with the USPTO. The USPTO encourages filers to use its EFS-Web system. This system allows you to transmit all your documents online. It is also necessary to pay the applicable filing fee for your food patent application. If you elect to submit your application on paper rather than through EFS-Web, the filing fee is increased by $400.
