Understanding Trademark Search by Class System: A Comprehensive Guide
A trademark search by class system is an essential process in the context of trademark registration. The classification system helps organize the goods or services used in applications, assess fees, and aid in searching a database of registered and pending trademarks. In this guide, we will delve into the concept of trademark search by class system, its significance, and strategies for effectively searching trademark classes.
What is Trademark Search by Class System?
The trademark class system, also known as the Nice Classification system, categorizes products and services into broad categories. This system was established by the Nice Agreement (1957) and is updated every five years. The latest 11th version of the system groups products into 45 classes, with classes 1-34 comprising goods and classes 35-45 embracing services.
Each class in the Nice Classification system has a unique number, ranging from 1 to 45. The goods or services are classified into these classes based on their inherent characteristics, and each class has a specific set of goods or services associated with it.
