Milk tea belongs to the 29th or 32nd category in the trademark. Trademark is a sign that distinguishes the source of goods or services, and each registered trademark is designated for a commodity or service. It is precisely for the needs of trademark retrieval, examination and management that some goods with the same attributes are combined into one category, and all goods and services are divided into 45 categories, forming a trademark classification table-"Classification of goods and services for trademark registration". Article 22 of the Trademark Law stipulates that an applicant for trademark registration shall fill in the category and name of the goods using the trademark according to the prescribed commodity classification table and file an application for registration. An applicant for trademark registration may apply for registration of the same trademark for multiple categories of goods through one application. The application for trademark registration and other relevant documents may be submitted in writing or in the form of data messages.
