In Taiwan, both invention and design applications are subject to substantive examination. According to the Patent Act, the applicant must file a request for examination of an invention application at the time of filing the application or within three years from the filing date. If such a request is not filed in an invention application within the statutory time limit, the application will be dismissed irrevocably. On the other hand, a design application will automatically go to the examination stage after the formalities are fulfilled with no need for the applicant to request examination. Therefore a design application could be approved quite soon after filing. Though this seems favourable, it may not necessarily be what the applicant wants, especially when the applicant wishes to defer publication of that specific design due to commercial considerations.
