All GCC countries including Saudi Arabia and the most of countries over the world are first to file system which means that ownership of a trademark is given to the individual who registered the trademark first and not to the one who use the trademark first. It is important to register your trademark in each country where your business is operating or is likely to expand to avoid losing ownership of your trademark if it is was registered by someone else prior to you. Obataining the trademark registration certificate in a particular country means that you are the only one who can use this trademark to identify and distinguish his goods or services and gives you also the rigth to prevent others from using identical or similar trademarks in country of registration.
