Q86. When the request should be filed?

A86. The request can be filed anytime within three years from the filing date. For a divisional application, a conversion application, and an application based on a utility model registration, a request for substantive examination can be filed within 30 days after filing such an application, even if the three-year period has been expired from the filing date of its original application.
 If no request is filed within the prescribed period, the application is deemed to have been withdrawn.
