2. Treat it differently according to different shapes. Such as tape recorders, televisions, vehicles and other three-dimensional modeling should be based on modeling, supplemented by patterns and colors; Carpet, wallpaper, printed fabric, etc. The pattern should be the main factor, supplemented by the shape, and the color difference should not be used as a separate condition to judge the similarity.

4. The size, material and function of the product are not the conditions to judge whether the design is similar.
