Patent Renewal Fee Calculator



Using the Patent Renewal Calculator


First, what’s the difference between a patent renewal, a patent annuity and a patent maintenance fee?

In reality, they are all the same thing, and all refer to payment of fees to the Patent Office to maintain your patent (or other IP right) in force. Different terminology is used in different jurisdictions.

What will the calculator tell me?

Based on your specific patent details, it will reveal the next renewal year in your patent’s lifetime, the deadline imposed by the patent office for the payment of the fee, and the value of the fee itself.


How do I calculate maintenance fees for several patents at once?

What is the processing fee listed?

This is our charge for assisting you in the payment of the renewal fee. Additional charges will apply if we have to use an agent, or if we incur additional costs. The estimated total includes all fees and charges, including the Patent Office fee and all other costs. To see your cases and check costs over time, simply save the patent to your account and then either log in or Sign Up here.


Are fees due on both applications and granted patents?

It depends on the patent office in the given jurisdiction. If it is not clear to us whether a case is granted or not, we may assume that it is granted to reduce the possibility of a fee not being paid.


What does ‘Save to Account’ mean?

If you already have a RenewalsDesk account, you can save this renewal to your account by using the same email address that you registered your account with. If you don’t yet have an account, click on the ‘Save’ button. The patent will be saved and you will be redirected to the sign up page. Once you have signed up, this renewal information will be waiting for you in your account.
