Intellectual Property Office

03:30 2022

In the table below we provide you with information about applications we have received to amend the specification of a patent under sections 27 and 75 before the court and the Office. The table also includes information about when you need to file an opposition if you wish to oppose the application to amend.

Where amendments have been filed electronically, you can obtain full details by selecting the patent number. If you are the patent owner(s), you should check these details carefully and inform us if there are any problems. Where amendments have been filed in paper form only, the symbol * appears in the table after the patent number.

In the case of amendments filed under section 75 before the court and under section 27 at the Office, reasons for the amendments are also provided.

You can obtain reasons for the amendments and full details of any amendments filed in paper form by contacting Litigation Section (telephone: +44 (0)1633 814334).

Opposition procedures

Section 75 before the court

If you want to oppose an amendment filed under section 75 before the court, you need to file a notice of opposition at the court. In the notice you need to set out clearly your reasons for opposing the amendment. You need to send us a copy of the notice and send a copy to anyone involved in the court proceedings. You need to do this within 14 days of the advertisement on our web site of the application to amend.

Section 75 before the comptroller and section 27 amendments

If you want to oppose an amendment filed under section 75 before the comptroller or an amendment filed under section 27, you need to complete and send us:

  • 2 copies of form 15 with the fee of 50. You will need to pay a further fee of 350 later
  • 2 copies of a statement setting out fully the facts of your case and what you want us to do
