Data quality
As part of its patent information activities, the EPO provides users with online patent data from more than 80 different countries.
To ensure a high level of data quality, we monitor the three main patent data streams (bibliographic, facsimile images and full text) at key milestones throughout their life cycle, to ensure that they are complete, consistent, accurate and up to date.
To help us maintain our high quality levels, we welcome user feedback on all issues relating to data from published patent documents. You can contact us via our DocHelp helpdesk.
