The publication of patent documents by way of this site is subject to a disclaimer in respect of the accuracy of replication

XML data for documents published prior to 1 January 2006 has been converted using a procedure that may result in accidental changes. It therefore cannot be guaranteed that XML data as rendered in HTML or made available in the ZIP file accurately replicates the respective original documents.

For documents published prior to 1 January 2006, only the PDF and SGML versions (in the ZIP file) are accurate replications or - in accordance with Decision of the President of the European Patent Office dated 12 July 2007 concerning the form of publication of European patent applications, European search reports and European patent specifications (Special edition No. 3, OJ EPO 2007, D3) - electronic publications of the respective original documents, as the case may be.

The HTML view is in all cases for users' convenience only. It cannot be guaranteed that this view accurately reflects the underlying XML data.

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 Symbol:  The search in the IPC field is conducted on the IPC Class as published on the patent document (e.g. A01B 45/02 or C07C 110/43). It is possible to search on the IPC class using truncation as follows (e.g. A01B or C07C 110)

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:

https://data.epo.org/publication-server/pdf-document?cc=EP&pn=nnnnnn&ki=nn

For example, for the document EP1502502A1, type.

https://data.epo.org/publication-server/pdf-document?cc=EP&pn=1502502&ki=A1

Please note that all the parameters are mandatory (cc, ki, pn)

Operators available for searching

The operator "OR" can be used in the Publication number or Application number search field: "861638 OR 897716 OR 912145".

Format of the European patent documents

The European patent documents were made available to the public in different formats in the course of the years.

The available formats are the following:

SGML - ST32 XML - ST361 PDF text PDF image via Espacenet Register
2006 onwards X X X X
2000-2005 X X X X X
1999 X X X X
1978-1998 in progress X X

Links to the Espacenet service giving access to the patent document stored as a PDF image in the EPO BNS database are provided for all publication periods

Please note that, according to article 158(1) EPC the European patent applications (EP-A documents) filed via the PCT route and already published by WIPO in one of the official language of the EPO are not republished by the EPO. Nevertheless, a link to the original PCT full text document is available from the hit-list.

1 XML for documents published prior to 01/01/2006 is not of publication quality. It has been captured from the original document using a procedure that may result in differences being introduced.
