Query publicationdate for B-documents

Post by martien » Fri Oct 13, 2017 11:57 am

Based on a more complex query, US9780384B2 was one of the results to watch for changes.
The same query with a newer pd doesn't deliver the most recent document.

If I search for pn=US9780384B2 I get the results US2015349348A1 and US9780384B2
For US9780384B2, today I see a publicationdate of 20171003,
for US2015349348A1 pd is 20151203

A combination of pd and the B-document doesn't work.
A query of e.g. "pd=20171003 AND pn=US9780384B2" doesn't deliver a result.

How can I find this newer document based on pd?

Hi,

Hi,

Smart search, or CQL as we call it is not the best option for numbers search, this is exactly why we offer number search separately. CQL should be used for date ranges, names, titles, classifications but not for numbers (it works most of the time, but in cases like yours it does not give proper response).

If you use DOCDB format and you make search as I did here you will get biblio and images URL for that new B document:

Code: Select all

Hi Support,

> CQL should be used for date ranges, names, titles, classifications
Exactly this is what I did (not knowing the pubnumbers) and where I found, that a document
that should be part of the result just isn't there.

It doesn't matter, with which terms I came to the original result.
The result of US9780384B2 disappears if the result "US2015349348A1" disappears, e.g.
famn:45493897 AND pd>20151201 seems ok.
famn:45493897 AND pd>20170101 is not ok, no results although a B2 document should be delivered.
Another point I found, is that "famn:45493897 AND pd>20151201" says "1 Result found", although two
documents are delivered. So does "pn:US2015349348A1"

Querying "famn:45493897 AND pd<20171003" delivered "3 Results found", although 6 documents were delivered.
To me it seems, that with a normal query without explicit searching for a pubnumber, you can get B-documents on which parameters like "pd" are not indexed/searchable.

Martien

B2 is definitely there and is a part of the same family, as shown if you do a full-cycle search for that US document

http://ops.epo.org/3.2/rest-services/pu ... full-cycle

What you are dealing here with is a feature of OPS and Espacenet (imposed due to the database feeding those services) where search results will really only show you applications/inventions and not also all their publication steps. In order to see those you need to add "full-cycle" constituent into your URL.

Also, please note that "pd" reference in OPS as well as in Espacent is actually the date of the first publication in the database only (first loaded to our database, not first laid open, although in most cases we do load that one first, but there are exceptions). This is also a reason why you cannot see 2017 dates in your search. If you repeat your searches in Espacenet you will see the same.

Your search query should look like this when you need to see all publication steps:

Code: Select all

http://ops.epo.org/3.2/rest-services/published-data/search/full-cycle?q=famn:45493897
http://ops.epo.org/3.2/rest-services/published-data/search/full-cycle?q=famn:45493897 and pd>20151201
About a number of results, as said, the whole CQL search is based on giving a result per application (so, one invention, basically) and this is why you get 3 results and each of them can have several publication steps, but those will only be displayed with a "full-cycle" constituent. Still, total count will remain the same even in full-cycle mode, but that is how the system is set so it cannot be changed, at least not for now.

Thanks for your reply.
I understand, what OPS is doing.
In terms of searching for new documents per CQL, it doesn't seem to be possible to search
for changes in B documents
