Changes as from January 1, 2009

Modification of kind codes

As from January 1, 2009, publication codes ("kind codes") used in order to distinguish PCT international applications published by the International Bureau of WIPO will be modified.

PCT international applications republished with alterations, amendments, corrections or supplements will be specifically distinguished from other documents by additional publication codes not previously used. The purpose of this change is to improve the usability of published PCT data and documents by more clearly identifying reasons for republication of PCT international applications.

In compliance with WIPO Standard ST.16 [PDF], the following publication codes will be used (additional codes denoted by italics):

Code Publication details
A1 International application published with ISR
A2 International application published without ISR
A2 International application published with declaration under Article 17(2)(a)
A3 Later publication of ISR with revised front page
A4 Later publication of amended claims and/or statement (Article 19) with revised front page
A8 International application republished with corrections to front page bibliographic data
A9 International application or ISR republished with corrections, alterations or supplements (see also WIPO Standard ST.50)

Example: Under the present system, an international application published with ISR would retain the publication code A1 after republication for any reason. Under the new system, the application would be assigned the publication code A4 if republished with amended claims.

International applications affected: Changes in publication codes will be reflected in all PCT international applications published or republished by the International Bureau on or after January 1, 2009. PCT international applications published or republished before that date will not be affected and will retain their original publication codes.
