Renew a patent
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’ll 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.
This service will be unavailable from midnight on Saturday 8 November 2014 to 7am on Sunday 9 November 2014.
- 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.
Tell the IPO in writing or renew by post if you want next year’s renewal reminder to go to a new address. IPO will send you a reminder letter if you don’t renew by the due date.
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 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.
