Are Chinese invention patents and utility model patents subject to substantive examination?

Applications for patents for invention are subject to substantive examination (novelty, inventive step and industrial applicability). Utility model applications undergo a formal examination only. However, in infringement disputes relating to utility model patents, the China National Intellectual Property Administration (CNIPA) will on request examine conformity with the relevant provisions and produce an evaluation report.
