It should be noted that the logo that can identify the source or producer of the product is not limited to the trademark logo or the name of the manufacturer, as long as it is the pattern, color or combination of two-dimensional printed matter mainly used for producing the logo function, it is excluded.
It should be pointed out that although textiles such as sheets, curtains and cloth are also two-dimensional products, they do not belong to "flat printed matter"; The color or pattern of textiles is usually not "mainly used for identification", so the design of these textiles is not excluded.
