Hello, the publication time of utility model patents and invention patents are not related to each other and depend on the examiner's examination speed. Utility model patents will not be disclosed until they are authorized, and the authorization time is generally about 6-8 months. If invention patents check early disclosure when applying, part of the content will generally be disclosed in about 5 months. You mentioned that other people's patent applications were later than yours, but they were published earlier than yours. In fact, this situation is very normal. Different examiners have different review speeds and case backlogs. Just wait patiently.
