Following theNotice from the European Patent Office dated 22 June 2021 concerning the introduction of Cooperative Patent Classification symbols in the European Publication Server, European Patent Register and European Patent Bulletinand our post in this Forum last year, we are pleased to inform you that all newly published EP original documents contain the CPC symbols (INID 52) on the first page since 19 January 2022 (publication week 03/2022).
Published publications in PDF format with CPC symbols (and C-sets) are now available on documents that can be retrieved from the European Publication Server and its API, the bulk data subscription product 14.12 EP full-text data and OPS.
Please note that in cases where the bibliographic data is more comprehensive, some information that is usually printed on the first page will be visible on the next page.
Any changes to CPC symbols after publication are available via bibliographic data feeds in ST.36 format as well as in tools or services that are based on that data set, e.g. DOCDB in bulk.
