2. Categories and goods and services should be selected from the list of similar goods and services according to the goods you have made. This classification table has an electronic version on China Trademark Network. According to what you said, it may involve multiple categories. You'd better find an agency to help you choose and register more comprehensively.
at the same time, it should be noted that only one category can be filled in an application. If multiple categories are involved, you should fill in the application form separately and pay multiple fees.
3. Trademark type: Generally, "General" is selected. Your goods are definitely not collective and proof goods, and "three-dimensional" refers to three-dimensional signs. "Color" refers to the commodity whose color is determined.
it is recommended that you do not specify a color. Where a color is specified, the color cannot be changed in use. Generally, the application is made in black and white, that is, "general" is selected, and the color can be changed at will during use.
4. If you don't need to specify a color, just stick a trademark pattern on the back of the application and attach 5 pieces. The size of the trademark pattern is between 5x5cm and 1x1, so it must be clear.
