First, I applied for an invention first, and now I want to apply for a utility model with the same technology. The utility model has not been substantially examined, and the previous invention does not affect the authorization of the latter utility model; If the invention can be authorized through continuous examination, you can choose to keep the invention for a longer protection period; However, if you consider that the examination period of utility model is short, the maintenance cost is low, and your technology does not need a protection period of 20 years, you can also claim priority.
Second, it is required that the priority of domestic applications does not need to provide a copy, and the application number can be indicated on the application form, and the National Information Bureau can obtain a copy of the application documents by itself. This provision has been explained in the review guidelines.
