Legal analysis: Legal, strictly speaking, it is a trademark transfer, which means transferring the exclusive rights of the trademark from the trademark applicant to another person. There are three ways to transfer a trademark (contract transfer, inheritance transfer, and trademark transfer due to administrative orders). The sale and purchase of trademarks is a contractual transfer in trademark transfer.

Legal basis: "Trademark Law of the People's Republic of China" Article 42: If a registered trademark is transferred, the transferor and the transferee shall sign a transfer agreement and submit the same request to the Trademark Office Make an application. 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. For transfers that are likely to cause confusion or have other adverse effects, the Trademark Office will not approve the transfer and will notify the applicant in writing and explain the reasons. After the transfer of a registered trademark is approved, it will be announced. The assignee shall enjoy the exclusive right to use the trademark from the date of announcement.
