The classification of trademarks usually follows the international classification system, that is, Nice classification. It classifies goods and services into 45 categories, of which 1 to 34 categories are applicable to goods and 35 to 45 categories are applicable to services. Each category covers a range of goods or services.
If you want to register a trademark, you first need to determine the category of your own trademark. For the field of information engineering, you may need to further determine the specific technical or service fields involved, and then choose the appropriate category according to the Nice classification system. According to the specific situation, information engineering may cover multiple categories, such as computer software (category 9) and scientific and technical services (category 42).
It is recommended to consult a professional trademark agency or intellectual property lawyer, who will help you determine the appropriate trademark category according to your specific situation and provide professional guidance and support in the process of trademark registration.
