yes. Before the patent is granted/rejected, the patent type can be changed from invention to utility model at the request of the applicant. Can only be converted once.

ATPO conducts formality examination and substantive examination of invention patents. The search report will be published together with the patent application within 18 months from the filing date, and the substantive examination will start automatically, and the applicant does not need to file a separate request for substantive examination. It can be authorized if the granted conditions are met.
