2.6 Publication of bibliographic data before publication of the application 

In accordance with Art. 128(5), the EPO publishes in the European Patent Bulletin the bibliographic data relating to European patent applications that had been announced for publication but for which the application documents were not published, either because the application was withdrawn or because the announcement was erroneous. The lists of these publication numbers can be found on the European publication server, which is accessible via the EPO website (epo.org).
