About this form

You must send an application for a certificate to the Norwegian Industrial Property Office within six months from the date when the first marketing authorisation for the product existed in Norway, or if applicable, from the date on which the patent was granted, if this is later. The issuing of a certificate can extend the period of protection by up to five years. The period of validity of the certificate becomes the period that has elapsed from the time when the patent application was submitted until the decision on the first authorisation to market the product in the EEA was notified, less five years.
