According to the relevant laws and regulations, the appended drawings of utility model patents are unqualified and cannot claim priority. The priority of utility model patent only applies to the application for invention patent, which requires that the patent should be applied for the same subject first, and then the patent should be applied for the same content. The purpose of priority is to protect the rights and interests of the first applicant in subsequent applications, but unqualified drawings will not affect the consistency of the subject matter. Where the drawings of the patent for utility model are unqualified, priority cannot be claimed, and the applicant shall resubmit the drawings that meet the requirements in accordance with the regulations.
