What coordinated classes are
Coordinated classes are trademark classes that sit close to one another within the standard NCL (Nice Classification) categories, because the goods or services they cover are related. They overlap, so a brand active in one class often has a natural connection to another.
Why they matter for your application
Businesses commonly grow into neighboring markets to reach more customers. To protect your brand properly, your application should cover the activities you carry out in these related industries. When choosing classes, look beyond what you do today and include coordinated classes that could support your future growth.
Using them in your search
Coordinated classes are also useful when you run a thorough trademark search. Checking them helps you spot possible conflicts before you file your application with the USPTO.
