Where can I see the latest coverage information for OPS?

OPS and Espacenet have the same coverage as far as bibliographic data goes.

For coverage information you can consult our Contents and coverage of the DOCDB bibliographic file table, which is updated weekly on Thursdays. Please note that OPS and Espacenet cover only content for actual patent publications, as opposed to DOCDB where you can also find other kinds of document (for instance Gazette notifications, kind codes A0 and D0).

Coverage of legal status codes and information on legal-status events and changes can be found at Coverage, codes and statistics.
