The European Patent Bulletin is updated on a weekly basis, and published every Wednesday at 14:00 hrs CET.
Publication number: the space between the country code and the publication number is mandatory (e.g.: "2 830 738").
IPC symbol: the search in the IPC field is conducted on the IPC class as published in the European Patent Bulletin (e.g. A01B 45/02 or C07C 110/43).
Over the years, the European Patent Bulletin has been made available to the public in different formats.
The PDF editions of European Patent Bulletin issues dating from 1978 to 2001 are scanned copies of the original paper documents.
Since 2002, the European Patent Bulletin is produced in character-coded, fully searchable PDF format only.
The PDF editions of European Patent Bulletin issues dating from 1978 to 2001 are scanned copies of the original paper documents. The EPO therefore cannot guarantee that these editions accurately replicate the original documents.
The PDF editions feature a hidden, searchable text layer that was generated automatically via optical character recognition without manual intervention. So, while searching for text and numbers is possible, it is not entirely reliable. The EPO cannot accept responsibility for incorrect search results.
The European Patent Bulletin is produced from the weekly EBD file, which provides details of all newly published applications and patents, as well as recent changes to previously published patents.
