I need help with an IP dispute

When you have to deal with IP litigation our team can help

If a person is infringing your IP, or if you need to defend against such allegations, we can help. We deal holistically with IP disputes. This involves experience and lateral pragmatic thinking to develop and deliver a range of different options and strategies to maximise your outcomes.

Our practical approach coupled with our commercial awareness is highly valued by our clients. It is these qualities, combined with our deep legal and technical expertise, that allows us to provide focused, useful, and competitively priced advice.

We work across all types of IP, clients and industry sectors. Our litigation services cover court proceedings in the UK and Germany,  revocation actions at the UKIPO and DPMA, domain name disputes, and alternative dispute resolution (ADR) such as mediation and international arbitration. We often collaborate with other professional advisors in complex multi-jurisdictional or parallel litigation cases.

In particular, we can represent all aspects of litigation at the UPC.

Our aim is to ensure clients benefit from creative, technically astute and joined up thinking when it comes to their IP strategy and that they achieve a commercially successful outcome. Please get in touch. We'd be happy to help.

The unitary patent and the unified patent court explained

The Unitary Patent and Unified Patent Court provides a new type of European patent and a new system for litigating patents in Europe.

Validity & infringement opinions from the UKIPO

The UK Intellectual Property Office (UKIPO) has a procedure to provide independent, non-binding opinions on questions of validity and infringement of UK and EP(UK) patents or SPCs based on such patents.

Why record changes of ownership at the EPO?

Recording a change of ownership on the EP register is not mandatory. However, we do highly recommend recording such changes in particular for the purposes of litigation.

EPO oppositions

A European patent may be opposed once it is granted. The opposition is handled by the European Patent Office (EPO) and so is a central procedure effective for all designated countries, i.e. the EPO opposition procedure is separate and in addition to national invalidity/revocation procedures.
