A registration with the government offices of the territory where you do business may grant you additional protections. For example, in the United States the government registration of your trademark includes, among others, 3 main advantages:
It provides brand exclusivity across the US, regardless of your actual place of business.
After five (5) years, your registration gives you a presumption of validity of your trademark.
Your company can benefit from the benefits of preliminary research before filing its trademark to assess the likelihood of confusion with third parties in the US before investing time and money in the deployment of the brand.
