2. What are trade mark classes and why are they so important?

In Hong Kong, trade mark registrations for goods and services are classified in accordance with the International Classification of Goods and Services under the Nice Agreement (see section 40(1) of the Trade Marks Ordinance). The list is internationally recognized and currently organized into 45 classes. It is important to register your mark in the correct class because it defines the category(s) under which your mark receives protection. If the mark is not registered in the correct class, you would not have protection under that class. If you apply to register the goods or services under the wrong class, the Registrar of Trade Marks will ask you to rectify the error during the application.
