How Long Do Patents Last?

When you get a patent, it doesn’t last forever—it has an expiration date. Utility patents, the most common type, last 20 years from the filing date, but you’ll need to pay fees to keep them active. Design patents last 15 years from issuance, while plant patents also last 20 years. Remember, patents give you protection only for a limited time, so it’s essential to make the most of that period to bring your idea to market and generate value.
