Utility Patents FAQs

How long does a utility patent last?

A utility patent lasts for 20 years from the date the patent application was filed. If the inventor first files a Provisional Application for Patent and then has a corresponding Non-Provisional Utility Patent Application granted, his or her patent protection will last for 21 years from the date the Provisional Application was filed. LegalZoom can assist you with a Provisional Application as well as a Non-Provisional Utility Patent Application.
