How long does a patent last?

The duration of a patent varies based on the type of patent and the jurisdiction. In most countries, a standard utility patent lasts for 20 years from the filing date. However, this duration can vary:

  • Utility patents: Typically last for 20 years from the filing date.

  • Design patents: Usually last for 15 years from the date of grant in the United States.

  • Plant patents: Typically last for 20 years from the filing date in the United States.
    It's important to note that maintaining a patent often requires periodic payment of maintenance fees to keep it in force for the full term.
