Syntax for the retrieval of European patent documents

The search allows several different criteria that follow a specific syntax as described below:

Publication number: the syntax should be country code + publication number.
The space between the country code and the publication number is optional (eg: 'EP0927553' or 'EP 0927553'). A leading zero is also allowed (eg: '0927553' or '927553')

Application number: the syntax should be country code + application number. The space between the country code and the application number is optional (eg: 'EP98123150' or 'EP 98123150')
The year may be entered as four or two digits (eg: 'EP1998123150' or 'EP 98123150')
A leading zero and the country code are optional (eg: '98123150')

IPC / CPC:  The search is conducted on the IPC/CPC symbols as published, e.g. G06N3/08. It is possible to use truncated symbols, e.g. G06N or G06N3.

Publication date: using the list box, select whether you wish to search using a particular publication date (during) or a range (between). Then select the year and week using the list boxes.

Kind of document: select the kind codes you wish to search by ticking the corresponding checkbox.

Direct access to the PDF document: When a PDF document is available, it is possible to access it directly using your browser via the following URL:
