When filing an application for a trademark registration it is always necessary to indicate the products or services for which the trademark will be used and therefore for which protection is desired. For administrative reasons, products and services are classified into categories, the so-called Nice Classification. This classification comprises 45 classes, of which 34 are product classes and 11 are service classes.
The classification determines the scope of protection of the trademark.
A thorough selection of the classes and the selection of the product and service designations is part of strategic considerations.
