With a U.S. trademark application or registration as your starting point, you can use one international application to request protection in the participating countries or regions you choose. This process is called the Madrid System. Each trademark office reviews your mark under its own rules and decides whether to grant protection in its territory.
You can also file directly in individual countries or regions. To claim the benefit of your U.S. filing date abroad, you generally need to file within six months and meet the applicable priority requirements.
The international registration depends on the basic mark for its first five years.
