The European Patent Bulletin is a weekly trilingual publication of the European Patent Office (EPO), generally issued every Wednesday. It contains "entries made in the Register of European Patents, as well as other particulars, the publication of which is prescribed by [the European Patent Convention (EPC)] or its implementation". The European Patent Bulletin is published in German, English and French, the three official languages of the EPO. The three texts coexist in the same issue of the bulletin. The European Patent Bulletin has been published online since January 2004.
