Patent application for cat

The difference between invention and utility model lies only in the degree of innovation. In the process of patent application, the invention patent has one more substantive application procedure than the utility model. You can choose to apply for a double application, that is, utility model invention. The examination and approval of utility models is fast, and the examination and approval of invention applications may take two years. Appearance only involves the new design of product shape, pattern, color or their combination.
