The application for patent for appearance has not come down for more than a year. Why?

Generally, an application for a design patent has to go through three stages: acceptance, preliminary examination and authorization, and the time is about 6-8 months. You can go to official website, China Patent Office to check the status of the design patent you applied for and whether it has been authorized by the State Patent Office. See if you failed the application or something. If you apply for an agent, contact the agent and let the agent help you solve it.
