EPO will accelerate oppositions when there are parallel UPC infringement or revocation proceedings

The EPO have announced in the November 2023 Official Journal that they will accelerate opposition proceedings when they are informed of infringement or revocation proceedings related to the same patent pending before the UPC or a national court/authority of a member state.

This is a change in practice – previously, the EPO would only accelerate an opposition if infringement proceedings were pending before the UPC or national courts/authorities. We consider this to be good news for all stakeholders.

This change was discussed at the EPO Opposition Matters Conference held on 23-24 November 2023. Here are some interesting takeaways from the discussion:

• The UPC/national courts will usually inform the EPO that there is an infringement/revocation action pending before it, and so the EPO will usually automatically accelerate the opposition proceedings.
• Alternatively, a party to the opposition proceedings may request accelerated processing.
• When opposition proceedings are accelerated, the aim is to issue the next procedural action within 3 months.
• Where a date for oral proceedings has already been set, they may be rescheduled to take place at the earliest possible date.
• We understand that this automatic acceleration of opposition proceedings only applies to first instance proceedings, and not necessarily the appeal stage (although, parties with a legitimate interest can still request acceleration of appeal proceedings).
