Opposition

Opposition and appeal proceedings before the European Patent Office (EPO) can be procedurally, technically and strategically complex. Our experience of these proceedings, representing both patentees and opponents, often involving multiple parties, makes EIP the firm of choice for clients seeking representation in these proceedings in all technical areas.

Expert team

Our team members have represented clients in hundreds of oppositions before the EPO over the last two decades.

By working collaboratively and sharing expertise we keep on top of the latest substantive and procedural developments before the EPO Opposition Divisions, Boards of Appeal and the Enlarged Board of Appeal.

Comprehensive service

We represent clients in person at hearings at the EPO in Munich, The Hague and Berlin, as well as using EIP's state of the art IT systems to ensure the best possible outcomes in videoconference hearings.

Our integrated team of patent attorneys, litigators and paralegals can act in national court litigation alongside EPO opposition proceedings for a seamless, consistent and effective service.

We are also experienced at using Third-Party Observations at the EPO and WIPO to challenge patent applications before they are granted, which for some clients may be a more cost-effective manner in which to address third-party rights of potential concern.

Maximising success

We work with our clients to devise customised strategies in order to maximise success in commercially important oppositions. This can involve steps such as strategic collaboration with other parties sharing a common interest and holding mock hearings to hone strategies and arguments before the official hearing at the EPO. Mock hearings can range from two attorneys arguing both sides of the case up to having independent consultants acting as the Opposition Division or Board of Appeal, with teams of attorneys, experts and clients attending.

Practice groups

EIP's patent, trademark and design attorneys work in specific legal and technical areas, with some having expertise in multiple areas, and are arranged in specialist practice groups.

Other practice groups

We have a wide range of in-house expertise with additional practice groups, all providing a highly integrated service offering to our clients.
