About this form

Please note that in international trademark registrations, the only changes you are required to report to the NIPO are change of representative. Other changes should be reported directly to the World Intellectual Property Organization (WIPO).

If the applicant has chosen to use a representative, the NIPO will communicate only with the representative in any correspondence regarding the application.

You can apply as an individual or on behalf of an organisation. If you represent an organisation, you must have the Altinn role Patent, varemerke og design.

You will find your receipt on the receipt page or in your Altinn message box. You may send a copy of the receipt by e-mail or save it to your device. NIPO will not send a receipt. You will receive a reference number in Altinn (ARxxxxx) which you can use for any enquiries.

Your notification will become public
Your notification will be published on our website. We generally shield sensitive and confidential information. You can ask us to exempt business secrets from public disclosure. It is therefore important that you clearly indicate what information in the notification or attachments you wish us to exempt. We will then assess whether the information can be exempted from public disclosure.
