How to change register details

It is important that the patent applicant or holder files all changes that concern Finnish patents with the Finnish Patent and Registration Office (PRH). It is in the patent holder’s interest that the registered details are up-to-date.

File the changes with the PRH if

• the applicant’s or holder’s name, address, place of residence (domicile) or registered office changes
• the patent or application is assigned to a new holder
• the representative or the representative’s details change
• the patent holder grants a right to use the patent, i.e. a licence
• a pledging is recorded in the patent

How to file the changes

File the changes with the PRH in writing. You can send the notification and enclosures to the PRH Registry by post, email or secure email. You can also hand in the documents at the PRH customer service point.

See the contact details for the PRH Registry.

Fees

There is no charge for filing changes when the application is pending. After the patent has been granted, filing changes is subject to a charge. However, it is always free of charge to:

• file changes to name, address, place of residence or registered office, and representative
• deregister an entry

Please pay the fee into the PRH’s bank account. Provide the number of the application or patent as the reference number of the payment. We will enter the details in the register once the fee is paid.
