What are the objects that the design patent does not protect?

Which of the following are not protected by design patents? What are the objects that the design patent does not protect? 1, depending on specific geographical conditions, fixed buildings and bridges that cannot be duplicated. 2. Products whose shapes, patterns and colors are not fixed because they contain substances with no fixed shapes such as gas, liquid and powder. 3. Indispensable, sold or used separately parts of the product, such as socks heel, brim, cup handle, etc. 4. For a product consisting of several parts with different specific shapes or patterns, if the parts themselves cannot become products with independent use value, then the parts are not patentable objects. For example, connectors that can't use the same connector to insert components with a specific shape or pattern can't be used alone, can't form an independent product, and can't give patent protection to designs. Only when this connector and other connectors that can be plugged into it are used as plug-in component toys and filed as an application for a patent for design, can the patent for design be protected. 5. It cannot be applied to articles whose shapes, patterns and colors are difficult to be determined by vision or naked eyes. 6. The design to be protected is not the conventional form of the product itself, such as the design of tying a handkerchief into an animal shape. 7. Design based on the original shape, pattern and color of natural objects. 8. Works that are purely artistic. 9. Only the geometric shapes and patterns that are common in the product field constitute the design. 10, the font, pronunciation and meaning of general characters and numbers cannot be protected as the specific content of design.
