How to convert patent applications to utility model applications

You can simultaneously apply for a patent and a utility model for an invention. What you can also do is to first apply for a patent and later ask us to convert your patent application to a utility model application. Please note: Neither methods nor uses can be protected with a utility model. In conversion, the original patent application remains pending if you do not withdraw it.

Only a pending patent application or a pending application for a European patent can be converted to a utility model application. An application is not pending if it is dismissed, rejected or withdrawn.

A converted utility model application is deemed to have been filed on the filing date of the original patent application or the original application for a European patent. However, a patent application cannot be converted if ten years have passed from its filing date. A granted patent cannot either be converted to a utility model application.


Proceed as follows

  1. Make sure that the patent application is pending on the day you are filing your utility model application.

  2. Draw up your utility model application in Finnish or in Swedish on the basis of the description, patent claims and drawings in the patent application. No abstract is needed. Replace the word “patenttivaatimus" by the word “suojavaatimus" (in Swedish: patentkrav -> skyddskrav). If the patent application contains method (process) or use claims, omit them from the utility model application. Do not add to the utility model application any new information that is not contained in the patent application.
  3. Fill in the utility model application form in Finnish or in Swedish. Tick the box "Muunnettu patenttihakemuksesta/Ändrat från patentansökan", and give the filing date, country and number for the original patent application in the field.
  4. Submit the application form, description, claims and drawings to the PRH. Pay the prescribed fees (registration fee and, if the number of claims is more than five, an additional fee for every claim exceeding five). Pay the fee(s) when filing your application or, at the very latest, two months from filing your application.
