  • Patent fees

Fees associated with filing patent application in Norway as well as other patent fees are available in the fee calculator.

  • The term for filing a patent application in Norway

The term for filing a patent application in Norway claiming priority is 12 months from the priority date. The restoration of this term is not stipulated.

  • Minimum of filing documents in Norway

The patent application in Norway should contain:
- name and address of the applicant(s) and representative;
- description of the invention.

  • Language of the Norwegian patent application

The official languages of patent prosecution in Norway are Norwegian and English.  If the application is submitted in English, the Norwegian translation of the patent claims should be provided before issuance of a patent.

  • Power of Attorney

The representation of the applicant together with the representative’s name and postal address must be cited either in the application form, which must be signed by the applicant or in a separate document. If the relationship of representation is based on a general power of attorney, each application in which the general power of attorney is invoked must contain a reference to it.

  • Priority document

In general, no priority document should be submitted. The Norwegian Patent Office may request the priority document at the examination stage, and the time limit for submission of the certified copy is three months from the receipt of the corresponding notification.

The novelty grace period applies if the application is filed within six months after such disclosure. Besides, since these exhibitions happen very seldom, this exception from the novelty requirement hardly ever applies.

The official fee for issuance of a patent in Norway should be paid within two months from issuance of the notice of allowance. This term may be extended for four months by paying the fine. The annual maintenance fees should be paid for pending applications starting from the 3rd year from filing the application, including the official fees for 1st and 2nd years.The fee may be paid within six months before the due date. The due date for paying annuities is the last day of the month in which filing occurred.Late payment may be effected within 6 months after the due date upon payment of a surcharge.

  • Representation by a patent attorney

It is recommended for foreigners to accomplish patent prosecution in Norway through an agent, a registered Norwegian patent attorney.
