At this time, the applicant's follow-up procedures are two very important data, which will be used many times, and the applicant should check them carefully. For example, the applicant for an invention should check whether the application number belongs to the invention type. If the patent office gives the utility model and design by mistake, it shall submit it to the patent office in time.
