Class 1 to Class 45

Classes 1 to 45 refer to the classification of goods and services in trademark registration systems. They help categorize items and services for legal protections. Classes 1 to 34 primarily cover physical goods, like chemicals (Class 1), household items (Class 21), and clothing (Class 25). Classes 35 to 45 focus on services, such as advertising (Class 35), education (Class 41), and legal services (Class 45). This classification ensures clear communication about what is trademarked, preventing confusion and protecting both businesses and consumers in the marketplace.
