Hi,

Please have a look at the OPS documentation, page 133, where you have all CQL field identifiers for OPS Published services listed. Documentation is avaialble here:http://www.epo.org/searching-for-patent ... .html#tab3


Just for information for otherwho might read this post; OPS Register has partially different identifiers and those you can see here: https://register.epo.org/help?lng=en&to ... identifier

Regards,
OPS support
