EPO - Discussion forums

Hello,

I'm trying to retrieve bibliographical information for epodoc=AT14924U1.
When I query for 'AT14924U1' the API returns 'No results found'.
The same for query 'AT14924' - 'No results found'.

But the document is finally retrieved when I query for 'AT14924U'.

The problem is with kind codes, right?
Where I can read more about correct processing of kind code?

Hi,

I am copying here an FAQ OPS answer about EPODOC numbers:

"...while OPS requires you to (a) specify the format you are using (DOCDB or EPODOC) and (b) use the format as specified. Typically, issues will appear when working with publications where the EPODOC format requires that kind codes (or parts thereof) be attached to the publication number.

For some publication authorities, the EPODOC format requires that (only a part - a letter) the kind code be attached to the number as follows:

[*] for Japanese publications (JP) an entire kind code (a letter and possibly a digit) must be attached to the number, except when the kind code is A;
[*]for publications with a country code on the following list: AT, AU, BA, BG, CN, DK, FI, IS, KR, NL, NO, PL, SK, UY, TW, YU, a kind code letter must be attached to the number, except when the kind code is A (does not need to be added at all, when A);
[*] for publications from all other authorities, a kind code letter must be attached to the number, except when the kind code is either A, B or C."

So, in your specific case, URL has to look like this:
.../published-data/publication/epodoc/AT14924U/biblio

Please note that as oppose to DOCDB, EPODOC is not a number format, its only a normalisation of numbers used mostly for Espacenet.

DOCDB is a proper number format and we have several concordance tables explaining it: https://www.epo.org/searching-for-paten ... gular.html

If you look at any random biblio query in OPS, you will see both formats there: I hope this helps,
