This database contains the whole collection of PCT patent applications published by WIPO . You can perform searches in the full text of these patent applications.
Under normal circumstances new patent applications are added to the database on a weekly basis (every Wednesday), around two weeks after publication. They are available in the worldwide database shortly afterwards.
Note (1): When viewing the bibliographic data of a PCT application in the WIPO database, you will not be able to see the patent families or the list of cited or citing documents, and the Mosaics and INPADOC legal status options will not be available. If you want to retrieve any of this information you will need to perform your search in the worldwide database.
Note (2): In this database, it is not possible to perform searches using CPC symbols.
In the EP and WIPO databases keywords can be entered in English, French and German.
