What is a Class Registration Number?
A class registration number is a unique identifier assigned to a trademark by the USPTO. It is used to identify the specific class of goods or services that the trademark is associated with. For example, Class 41 represents educational services, while Class 42 represents computer software. By searching by class registration number, you can quickly identify potential conflicts with existing trademarks in the same class.
