Nice classification is a system used to categorize goods and services for the purpose of trademark registration. It was established by the Nice Agreement in 1957 and is maintained by the World Intellectual Property Organization (WIPO). The classification consists of 45 classes, with 34 classes for goods and 11 classes for services, each representing a specific category of products or services. This classification system allows for the easy identification and organization of trademarks, making it an essential tool for businesses and trademark offices around the world. The Nice classification is constantly evolving to keep up with the ever-changing landscape of goods and services, ensuring that trademarks are accurately and efficiently classified.
