Notes about interational trade mark registrations. Registration of trademarks in a number of different countries can be a complex process. Part of our service is to smooth that process for you, but there are still some parts which may require additional steps and/or fees. For example, some countries require an authenticated Power of Attorney to be filed together with the application, which can incur additional cost. Other countries have a slightly different process, like the United States who require additional information as part of the application (which if not available at the time of application, would need to be filed after at additional cost) and also require a maintenance fee between the fifth and sixth year of registration. Finally, our fee estimate is subject to changes in exchange rates, local government and local agent fees.
