Due to maintenance on the EPO
systems on Saturday 23 October, from 08:00 until 18:00 our customers might notice that
on receipts for form EP 1200 the European application number is missing on the
receipt, whilst the PCT application number is shown. In such cases the European
application number can be received from EPO support from Monday onwards. It is
also shown on EP Form 1201 and can be seen in the European
Patent Register in due course. For information on how to reach us, visit http://www.epo.org/contact.
