Advanced Search

The Advanced search form has the most sophisticated interface of the various search forms. It provides separate text fields for all the data elements that can be searched via Espacenet, eleven in all. Due to the large number of fields, the interface naturally looks more crowded than other forms, but it greatly increases the available search options. However, one feature is lost: the Advanced form does not offer the combined inventor/applicant search that can be conducted from the Quick Search interface. The “Quick Help” topics still appear on the left side of the screen.


The Advanced Search Form.


The Advanced search form will also change when the EP database is selected. When conducting a search in the EP database, the ECLA field isn't present, but a field called "keyword(s) in full-text" can be used to search within the full-text claims or description of the patent document. (For more on the content of the EP and WIPO data files, see The EP and WIPO Databases.)

Both date range searches and full-text searching for the claims and descriptions within EP documents are now available. Date ranges can be searched by entering any of the following formats to specify a date range between two years: 2005:2007, 2005,2007, or "2005 2007." [1] Full-text searching within the claims and descriptions of some EP documents can be conducted in the Advanced search by searching the field "keyword(s) in full-text."

editors note iconEditor's Note:

A drop-down menu format that allows the user to select the data element for each text field would be more user-friendly and less crowded than the Advanced search form's current format of a text field for each available data element.
