When do I have to renew my patent?

Renew it on the fourth anniversary from the date on which it was filed and every subsequent year thereafter.

Is my patent perpetual?

The reader should not be mislead by the above words: "...and every subsequent year thereafter." In that you can renew your patent up to 20 years.

How do I renew my patent?

This is done by completing and filing Patents Form 12 paying the relevant fee. See also Patents rule 36.

What is the "relevant fee"?

5 = £70

6 = £90

7 = £110

8 = £130

9 = £150

10 = £170

11 = £190

12 = £210

13 = £250

14 = £290

15 = £350

16 = £410

17 = £460

18 = £510

19 = £560

20 = £600

Where do I send Form 12?

Renewals should be sent to:

Intellectual Property Office

Concept House

Cardiff Road

Newport

South Wales

NP10 8QQ

United Kingdom

Or by fax: +44 (0)1633 817777

If you do not file your renew on time the UKIPO will send a reminder to the proprietor giving you an extra month in which to submit your renewal.

The proprietor has an extra five months to renew but will have to pay £24.00 late renewal fee.

If you do not pay your renewal fee by the payment due date we will issue a reminder letter and you can still renew it up to 1 month after the payment due date at no extra charge. If you are "out of time" the proprietor can restore the patent up to 13 months after the initial 6 month period.
