PCT ap­pli­ca­tions to the PRH

We are a Receiving Office (RO), and you can file your PCT application with us, and thus start an international PCT procedure in Finland. We will first check that your application meets the formal requirements. Then it will be handed over to an International Searching Authority (ISA).

We also act as an ISA and an International Preliminary Examining Authority (IPEA). This means that you can choose us to process your application.

The PCT application form (‘Request’) is in English. If you submit your application to us, your application documents may instead be in Finnish or in Swedish. However, they must be translated into English later on. If you choose us as the ISA, you must file a translation 14 months from the priority date at the latest.

If you want us also to carry out an international preliminary examination of patentability, you can also file your demand for that with us.

You can submit your PCT application to us either online, by post, by secure email or by fax. You can also file other documents, such as your demand, replies to PCT office actions, and subsequent documents, by the above means. Below you can read brief descriptions of the above means of filing documents.
