Our customer service in Helsinki will open with restricted opening hours on 28 February 2022

The Finnish Patent and Registration Office (PRH) will open its customer service in Helsinki on 28 February 2022 after being closed due to the coronavirus.

The service will be open from Monday to Friday between 12.00 and 16.15 until further notice.

There are instructions for our walk-in customers at the customer service entrance (Sörnäisten rantatie 13 C).

Our online and telephone services will be running normally

You can send paper notifications by post to Finnish and Patent Registration Office, FI-00091 PRH or leave them in our mailbox on the wall of our office building. We recommend that you use our online filing service. It is quicker and cheaper to file online than using paper forms. Our online services and information services are available at the prh.fi website.

Our customer service number is 029 509 5030 and it is open Mon–Fri 9.00–15.00.
