The United States uses the Nice Classification System in terms of class number; however, they use their own identification system of goods and services to determine the class description. The difference between the Nice Classification identification of goods and services and the US identification of goods and services is that the US requires the items to be broken out to describe the goods/services in more detail. For example, “clothing” must be broken down to “shirts, pants, skirts, etc." If you order a Comprehensive Study in the USA, within the study our attorney will recommend the description that should be included in the trademark registration request.
