1. Digital products are mainly in category 9 of the classification table, in which mobile phones belong to group 97, which includes all communication equipment, and accessories such as batteries on mobile phones belong to group 922; Products such as MP3 and MP4 belong to the 91 group. Because the classification table is divided by large product attributes and characteristics, there is no clear title such as MP3 and MP4, but they are all called "data transmission media".

2. If you plan to expand the range of goods registered with the trademark in the later period, you can't directly add the product to the protection range of the original trademark, and you can only register the goods to be protected.

3. When registering, if you entrust an agent to help you with the registration, you only need to provide a copy of your business license and a trademark sample, and other documents and materials and specific operations are handled by an agent.

4. I'm a regular trademark agency in Beijing, so if you need any other advice or help, you can leave me a message on Baidu hi at any time.
