Why trust the PRH?

We carry out patentability searches and examinations, and our work quality is under regular control and improvement. We employ 100 highly educated examiners, and offer a variety of services. You are welcome to take advantage of our expertise.

We provide you with a reliable assessment on whether your invention might be patentable, which will help you plan cost-effectively when and to what extent it would be rational to proceed with patenting. Even if you are aiming at patenting beyond Finland, it may be a good idea to start the process by filing a national application with the PRH.

We also offer a route for businesses that operate in the international market and apply for the protection of intellectual property through other countries’ or international systems.

Route for international patenting

A national patent application is a cost-effective way to start international patenting.

  • Your national application can be written directly in English.
  • After the application has been processed, it will be easier for you to decide whether to pursue the application outside Finland, in which countries, and whether you should amend the application.
  • We also receive and process international PCT applications.
  • If you choose the PCT route, you can delay your decision on where to pursue the application by up to 2.5 years.
  • If you want patent protection quickly, you have the possibility to fast-track your application at any authorities which are members of the PPH system.
