Legal analysis: Currently, there are two main methods for trademark transactions: 1. Go to the registration hall of the Trademark Office to transfer the trademark by yourself; 2. Entrust a trademark agency to transfer the trademark.

Legal basis: "Trademark Law of the People's Republic of China"

Article 15 Without authorization, an agent or representative shall use the agent's or representative's own name to If the represented person's trademark is registered and the principal or the represented person raises an objection, the trademark will not be registered and its use will be prohibited. A trademark applied for registration for the same kind of goods or similar goods is identical or similar to an unregistered trademark previously used by another person, and the applicant has a contract, business relationship or other relationship with the other person other than those specified in the preceding paragraph and is fully aware of the existence of the other person's trademark. If the other person raises objections, the registration will not be granted.

Article 41 If a registered trademark needs to change the name, address or other registration matters of the registrant, an application for change shall be submitted.

Article 42 If a registered trademark is transferred, the transferor and the transferee shall sign a transfer agreement and submit applications to the Trademark Office at the same time. The transferee shall ensure the quality of the goods using the registered trademark. When transferring a registered trademark, the trademark registrant shall transfer all similar trademarks registered on the same goods, or identical or similar trademarks registered on similar goods.
