Fees

Application fee and late fee

If you did not pay the application fee when you filed (2. Get a filing date), you need to pay the application fee and the late fee. We will send you a notice that tells you which fees you need to pay. You'll have 3 months from the notice date to pay your fees or your application will be withdrawn.

Maintenance fees

To maintain your patent, you must pay an annual maintenance fee starting on the 2nd anniversary of your filing date. For example, if you file on January 31, 2022 , your first maintenance fee will be due on January 31, 2024 .

• You must pay your maintenance fees on time.
  • We will not send reminder letters letting you know that a maintenance fee due date is approaching.
  • If the full required maintenance fee is not paid on or before the due date, a late fee must also be paid.
  • The late fee can never be waived.
