Hi,

The searches as you are trying to do are not possible in OPS.

You have a list of all possible queries in Testing console; https://developers.epo.org/ and all available field identifies that you can use in CQL search are in OPS documentation on the website: https://www.epo.org/searching-for-paten ... s/ops.html - Look under CQL index and CQL queries.

As you will see, filling date is not available for such queries, this is why OPS is also not a tool to be used for monitoring or watch service. Firstly, because you cannot do such queries and secondly, because OPS returns only first 2000 hits for every query.
