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, it is a good idea to use the international application system known as the Madrid Protocol. By filing one application you can apply for trademark registration in many countries at the same time.
A professional patent agency (or patent attorney) can assist you in preparing your trademark application and keeping track of important deadlines and payments.
Norwegian representatives can represent their clients in trademark cases in all stages of the application process before the European Union Intellectual Property Office (EUIPO), formerly OHIM.
