Annual renewal fees
Annual renewal fees must be paid on your patents if you want them to remain in force. It is up to you to pay them on time.
The cost will vary depending on the type of patent and the number of years that have passed since you originally filed it. These fees are usually due on or before the anniversary of the filing date of your complete application.
You start paying renewal fees on the second anniversary of the filing date, paying annual fees for the first three years. Renewal fees are then due each anniversary after that until the patent ceases.
The first payment of annual renewal fees is on the second anniversary of the filing date.
You can view your patent in the patent search to check the date on which your renewal fee is due.
One option to ensure the renewal fee is paid on time is to arrange for an annuity firm or a patent attorney to keep track of the due date and forward your payment to us.
