Hello, not all groups selected during trademark registration can be used freely. Although group products can prevent others from infringing, if you want to use them yourself, it is recommended to add registration.

1. If you register the 11th category and have approved 110337 under the 1104 group, and there are no other general product items, it is recommended to resubmit registration 110356 if you want to sell air fryers.

2. If you want to develop and sell other cookware in the future, you can choose to add general items (such as 110107 electric cookers, 110109 cooking devices and equipment, etc.), so that you do not need to add registration every time in the future. Applied.
