Are Chinese patents for invention and patents for utility model subjected to substantive examination?

Updated: Nov 26, 2017 SIPO ENGLISH Print

Patents for invention are substantively examined (novelty, inventive step and industrial applicability).

Patents for utility model do not undergo a substantive examination but only a preliminary examination (compliance with formal requirements). However, in invalidation procedures the requirements of novelty, inventive step and industrial applicability will be determined.
