J A Kemp Webinar: Auxiliary Requests at the EPO

May 20, 2021 @ 2:30 pm - 3:30 pm BST

A unique feature of pre- and post- grant procedures at the European Patent Office is the ability to file auxiliary requests. An auxiliary request is an auxiliary claim set which is filed at the same time as the main claims which are being pursued. The auxiliary request is only considered if the EPO deems the main request claims to be unallowable. Auxiliary requests may be filed during the written examination or opposition procedure, and it is standard practice to file auxiliary requests immediately before oral proceedings. Auxiliary requests can also be filed under special circumstances during oral proceedings. There are many rules to navigate as to what an auxiliary request may relate to, when an auxiliary request may be filed, how many auxiliary requests can be filed, admissibility of auxiliary requests, etc. This webinar will examine what an auxiliary request is and when filing an auxiliary request should be considered as well as exploring tactical considerations relating to preparing and filing of auxiliary requests.

Topics will include:

  • When can you file an auxiliary request
  • Timing of filing auxiliary requests
  • Number of auxiliary requests
  • Tactics relating to which auxiliary requests to file and when
  • Admissibility of auxiliary requests

This is a technical webinar aimed at:

  • Overseas attorneys and inventors involved in prosecution of European Patent Applications
  • Attorneys and inventors involved in oral proceedings at the European Patent Office
  • People involved in oppositions and appeals at the European Patent Office


This webinar is available live and on-demand.  If you cannot watch it live, sign up anyway and watch on-demand at a time convenient to you.
