Searching with PCT publication numbers
Depending on the year of publication, you can enter three different PCT publication number formats in the Register. The number format has changed over time as follows:
The format valid from 1 January 2014 onwards is also the standard format and can be used for all PCT publications. It consists of the WIPO code WO (two letters), the year (four digits) and a serial number of six digits: WOyyyynnnnnn.
In the Register, patent document numbers entered in Smart search trigger a search for all types of patent documents, i.e. the Register searches for application, publication and priority numbers, using the search syntax num =. If you want to search for a particular type of patent document number, you can use a corresponding Smart search field identifier. If you only want to search for the publication number, for example, you enter your search using the field identifier pd= followed by the number, e.g. pd = WO2007IB51010. In Advanced search you simply enter the numbers as they appear in the corresponding search fields.
