A trademark registration applies only in the country where it is registered. If you wish to register a trademark outside Norway, you should consider carefully in which countries you wish to secure rights to production and market access.
If you are planning on using your trademark in several countries, you can use either the international application system known as the Madrid Protocol or you can send en application to the EU trademark authority EUIPO.
A professional patent agency (or patent attorney) can assist you in preparing your trademark application and keeping track of important deadlines and payments.
