One unique aspect of China’s trademark examination is cross-class similarity. CNIPA maintains a “Classification of Similar Goods and Services” document that groups certain classes together when examining likelihood of confusion.
Example Group 1: Class 9 (computer software) and Class 42 (software development services) – considered similar in many contexts
Example Group 2: Class 35 (advertising) and Class 41 (education/entertainment) – may be considered related
Example Group 3: Class 43 (catering) and Class 30 (coffee, tea) – related for food service brands
When filing your trademark, consider filing in multiple classes within the same cross-class group to ensure comprehensive protection. Our experienced agents can advise on cross-class strategies based on your specific industry.
