Since July 1, 2017, designated Offices have been required to notify the International Bureau of information concerning international applications which enter the national phase at their Office.

Display of information in the National Phase tab of PATENTSCOPE for an office indicates that the applicant requested national phase processing for the application concerned in that office. The national entry date and national reference number are supplied by the national office concerned and can be used to retrieve further details from that office, if desired. Please note that absence of information for a given office does not necessarily indicate a non-entry in that office.

While the supply of information has improved since the requirement entered into force, further work needs to be done to improve the breadth and quality of the data and the timeliness of its transmission. The information is therefore updated at different frequencies, depending on the office.
