EPODOC format of CN between DOCDB and espacenet

Post by patentfield » Sun Jul 05, 2020 8:18 pm

We recognize that the EPODOC number format rules are as follows.

However, Espacenet and DOCDB CN application numbers may have different numbers of digits.

- 6digits

Hi,

No, your link is for DOCDB format and not EPODOC. DOCDB format has in this specific case more 0 for application numbers, but not for publication numbers. Publication numbers of DOCDB and EPODOC look almost identical, the biggest difference is in application/priority numbers, as your CN case shows.

DOCDB is format used in New Espacenet and OPS
EPODOC is format used in Espacenet Classic and OPS

I understand that the link is a docdb rule.

However, the CN application number in EPODOC format seems to have different numbers of digits.

Is there any document on the format rules of CN application number in EPODOC format?

Hi,

EPODOC, as oppose to DOCDB, is not proper numbering standard, its just a legacy product, a simplification of numbers so that Old Espacenet can be searched better. So, no, rules as for DOCDB do not exists for external users.

As said already in my previous post, New Espacent which is a new standard, doesn't not use EPODOC anymore and so does most of products and services. I would suggest that you rather focus on DOCDB format, for which you have rules and tables you can always refer to. We will keep EPODOC until we have new webservice and until Espacenet Classic is still operational but at some point we will discontinue that - don't ask me about when, I would not be able to reply at this point.
