EP numbering format / system
Posted: Sun Aug 07, 2022 11:00 am
Hi everyone,
I would like to ask what possible numbering formats there are for European Patents. Can there be a patent number with more than 7 digits? As I currently understand, possible formats are:
EP X XXX XXX A1 / A2 / A3 / A4 / A8 / A9 / B1 / B2 / B3 / B8 / B9 / W1 / W2
But can there be a patent with e.g. 8 or more digits like
EP XX XXX XXX B1
On the EPA page I could only find the Basic Definitions (https://www.epo.org/searching-for-paten ... tions.html) and information on the numbering system of other countries like e.g. Japan (https://www.epo.org/searching-for-paten ... ering.html).
Many thanks!
