EPO Confirms New Accelerated Opposition Timelines

Further to the EPO notice on acceleration of Opposition proceedings, they have now confirmed timelines for the various stages:

  • Opposition reply will be due within three months (instead of the usual four months)
  • Summons to Oral Proceedings will be issued within two months of receipt of the Patentee’s reply
  • if the Patentee has already replied, the Summons to Oral Proceedings will be issued within two months of receipt of the information on parallel proceedings
  • if the Summons to Oral Proceedings had already been issued, Oral proceedings are rescheduled to the earliest possible date (provided that the time saving is significant)
  • the written decision and minutes will be issued within one month of the Oral Proceedings announcing the decision

These acceleration measures apply with immediate effect and also to pending proceedings.
