Is "famn-id" persistent in EPO OPS?
Posted: Wed Dec 07, 2016 12:15 pm
Dear OPS Forum members,
I am working with the extraction of patent families for certain application names.
I understood, that we can not retrieve a list of all patent families for an application name, but only for a publication ID. That is ok for now, but I would like to know, if the "famn-id" (aka simple family identifier) is a persistent number and does not change over time.
In one of the forum entries I read something about recalculating these numbers every week, but it might have been related to another service.
Can someone comment if this simple family identifier is a reliable ID, which does not change over time?
Thanks a lot,
Nisse
