CQL query issues

Post by afedosenko » Wed Jun 20, 2018 12:46 pm

For example, the WO2017123335 number has application original number US2016/064351:
http://ops.epo.org/3.2/rest-services/pu ... 335/biblio

When I am trying to find this number using the search API, I get two different results, depending on the version of the API:
  1. http://ops.epo.org/end-of-life/rest-ser ... 016/064351
    The result contains the WO2017123335 number. And the CQL query in the result look like as <ops:query syntax="CQL">num = "US2016/064351"</ops:query>
  2. http://ops.epo.org/3.2/rest-services/pu ... 016/064351
    The result doesn't contains the WO2017123335 number. But the result contains the "rest-services/published-data/publication/epodoc/US2016064351/biblio" number instead. And the CQL query in the result look like as <ops:query syntax="CQL">num = "US2016064351"</ops:query>(witohut slash).
How can I find the WO2017123335 number using the application original number US2016/064351 in the new version(3.2) of the API?

If you want to use CQL instead of OPS Number search (not the best option though) your query has to look like this:


CQL search in OPS does not search full-text search option like Espacenet so you need to use properly filed identifiers in combination with either epodoc or docdb format number in a query.

but a much better option for searching numbers is:

You can not use original number format any of our services (maybe Espacenet TXT search would find something but even that is quite risky and can bring quite some noise)

DOCDB number format tables are available here: https://www.epo.org/searching-for-paten ... gular.html
