Renew your GB patent or European patent (UK) online.
When to renew
You must renew your patent on the fourth anniversary of when you filed for it. You then need to renew every year near the ‘due date’ - the last day of the month in which you first filed.
Renew up to 3 months before, or within 1 month after, the due date to avoid late payment fees.
You can renew up to 6 months after the due date but you’ll have to pay £24 on top of the renewal fee for each extra month.
- your patent number - starting ‘GB’ or ‘EP’
- a debit or credit card, or an Intellectual Property Office (IPO) deposit account
- an email address - you’ll be emailed your certificate of payment
You can renew your patent for up to a maximum of 20 years.

You’ll pay any late payment fees when you renew.
When you renew your patent online, you can ask the IPO to email you a reminder a month before the next due date.
If you don’t renew your patent on time, the IPO will send you a reminder by post. They’ll use the last address you provided. If you want it to be sent to a new or different postal address, you should write to the IPO or renew by post.
Patents granted later than 3 years and 9 months after the filing date
Your first renewal is due 3 months after your patent was granted. You’ll need to pay the fee by the last day of that month.
You may also have to pay multiple fees that cover more than one renewal year when you pay your first renewal fee.
You can visit a regional Patent Information centre (or Patent Library) if you need help renewing a patent online.
