What document do you have to sign?
In some cases, the regulations require certain documents to be signed. This applies, for example, when you are going to:
- apply for, change or delete industrial rights
- submit objections and administrative reviews
- give a power of attorney that gives someone else the right to act on your behalf
What requirements apply to handwritten signatures?
NIPO accepts:
- a handwritten signature on a paper document
- an electronic copy or a scan of a signed paper document.
This also applies if you have only used electronic aids to create a document with a handwritten signature.
Paper communication must be juxtaposed with electronic communication. Therefore, we accepted handwritten signatures, even if this is not so secure in terms of authentication and information security.
We did not accept typed names as a valid signature
Below on the left are some examples of approved, handwritten signatures that have been created using an electronic pen or similar, or they are a copy of a handwritten signature.
To the right are examples of unapproved typewritten names using different fonts.

Electronic signature from Altinn
We accepted an electronic signature created by Altinn from a person who is authenticated using a Norwegian social security number in the national ID-en‐porten.
Altinn is the primary internet portal for digital dialogue between business, private individuals and public agencies in Norway.
Altinn provides secure transmission through authentication and receipt. Documents received from Altinn are automatically and quickly imported into the NIPO's system.
- You can tick the box for signing so that the document you are sending is affixed with an electronic signature.
- You can also use Altinn to send over a document with a digital reproduction of your handwritten signature.
How can you use Altinn without a Norwegian ID number?
You can also use Altinn without access to login via the Norwegian ID portal.

Why should I sign a document?
The purpose of the signature is to link a person to the document being signed.
The signature requirement should help you to have confidence in the information in NIPO's register. This is even though, as a general rule, it is always the underlying situation that will be decisive in the event of a dispute.
What happens if I sign the wrong way?
NIPO determines the standard for electronic signatures at all times. If you sign incorrectly, NIPO will contact you to have the error corrected.
Future changes
We are working to establish a system to accept multiple types of electronic signatures. We will regularly review which signatures we can accept and will continuously update the information on our website.
