Search results or the contents of folders can be exported to XML.
It is possible to export the whole result by selecting "Whole result"
or selected patents via the option "Selection".
Here the same data as in the Excel-Export can be selected for the XML-Export.

The XML-Export is especially suitable for exporting particularly large result lists.
The structure of exported XML-data follows the WIPO-Standard ST.36.

This standard was selected in order to easily facilitate the import of XML-data to other tools (e.g. patent administration software).
