Under Norwegian law, the exclusive right to use a trademark may be obtained either by registration or by established use of the mark.

A trademark may consist of any sign capable of distinguishing the goods or services of a certain entity from those of others. It must also be capable of being represented graphically, such as words, slogans, names, device marks, letters, numerals, the shape of the goods and its packaging.

Applications to register trademarks are handled by the Norwegian Patent Office, a government authority organized under the Ministry of Trade and Industry.

A registered trademark is subject to user-requirements, and provided timely renewals are attended to, the registration is valid for 10 years at a time.

Norway is a party to the Madrid Protocol. However, as Norway is not a member of the European Union, CTM applications will not cover Norway.
