Why has China adopted the utility model patent in addition to the invention patent?

The purpose of adopting utility model patents is to provide lower cost protection, with a Patent Certificate that issues quickly, for "low-tech" and short life-span inventions or for those that are likely to be copied as soon as they enter the market. Since applications for utility model patents are usually given a preliminary examination only and often no search is made to determine whether the invention is already known, examiners qualified in technical disciplines are not required and this significantly reduces the cost and the time taken for the Patent Office to complete its examination.
