An invention refers to a new technical scheme proposed for a product, method or its improvement.
Utility model refers to a new technical scheme suitable for practical use for the shape, structure or combination of products.
Appearance design refers to a new design with aesthetic feeling and suitable for industrial application based on the shape, pattern or combination of products and the combination of color and shape and pattern.
It is generally believed that inventions are more scientific than utility models. In fact, there is no essential difference between invention and utility model in content requirements, but there are differences in approval procedures and patent protection years. In the process of patent application, invention patents need substantive examination, and the examination and approval time will generally be extended to 2 to 3 years, while utility model patents do not need substantive examination, and the examination and approval time will be reduced to 8~ 10 months. After the patent is granted, the right protection period of the invention patent is 20 years, while the utility model patent is 10 years.
