The source of legal status in this container is INPADOC data from the European Patent Office, covering a variety of entries, procedural steps, and post-grant events from over 50 patenting authorities. Premium Plus subscribers also receive legal status data in English from our new Chinese data source (see Chinese Data Improvements for more details). Content and coverage varies, and all legal status codes are country-specific.
A list of worldwide legal status codes, contents, and coverage can be found on the EPO’s website at https://www.epo.org/searching-for-patents/helpful-resources/data/tables/weekly.html. For several authorities, more detailed explanation of the codes can be found at https://www.epo.org/searching-for-patents/helpful-resources/data/tables/legal-status-codes.html.
