What is the approximate group number of trademark registration?

Trademark registration is divided into 45 categories according to the nature, function or service of goods, and different small groups are distinguished in these categories; For example, 1 1 class has 13 small groups. 1 10 1 (lighting equipment), 1 104 (cooking and heating equipment for household appliances), 1 106 (dry ventilation and air conditioning equipment),/kloc-0 19 includes 15 group, such as 1904 (cement), 1906 (building tiles),191(building glass and glass materials) and so on. If it is not specified that each small similar group is similar to a certain group, then they are independent of each other and do not constitute similarity. For example, the trademark you want to register is similar to the previous trademark standard samples, both of which belong to the category of 19, but the product protection range you chose before is in the group of191,and the protection range you chose is 65438.
