Cannot find patent Check-digit

Post by BoxClever » Thu Jul 04, 2019 1:02 pm


I would like to know where our automated system can lookup the EPO checkdigit number.
(for example: The ‘.8’ at the end of EP13748138.8)

We have an automated system that will be instructing the EPO via the EPO PMS Gateway.

But I cannot find a service that provides the patent number checkdigit for a given patent number.

I do not understand why:
• The EPO generate a number (we cannot get it from anywhere else)
• The EPO require that number when instructing via PMS Gateway
• The EPO does not make that number available via OPS

Is there some other EPO service, which our automated system could access to get the checkdigit ?

I suspect there is something I do not understand.

[This further to: application-number-in-register-page-8238 ]

Kind regards

If you want to have a list with applications that have check digits you can use either EBD weekly files that we offer under Bulk Data: ... ml#tab-1or you can use a web service from European Publication Server: ... html#tab-1

But OPS does not offer application no with check digits, no.
