Our professionals make use of a range of experience including their past in-house expertise in order to deliver commercial solutions to our clients’ disputes, whether through formal proceedings or by alternative dispute resolution such as mediation or arbitration.  Our professionals have experience of advocacy in several jurisdictions, and at all levels of courts, so we can guide you in oppositions, court based disputes and all forms of alternative dispute resolution.

For advice on alternative dispute resolution from mediation to arbitration, we have amongst our professionals qualified and experienced arbitrators, mediators and tribunal chairmen. If you are facing a dispute, or want to assert your rights by way of arbitral proceedings, we are here to help.

What you need to know

Intellectual property rights have an intrinsic value to a business. If those rights are infringed, it is important to act quickly to assert, or if necessary, defend your rights.

How we can help

We advise on how to deal with suspected infringing activities or products, or with threatening letters received from a competitor. In some circumstances, issues such as these can be resolved quickly by engaging proactively with the other party. However, where matters escalate, we are able to provide practical and strategic advice both before and during any court proceedings that may result.

Our team includes barristers and solicitors, as well as patent and trade mark attorney litigators, all with first hand litigation experience both in the UK, Europe and the Americas. We are skilled at all types of dispute resolution including mediation, arbitration, opposition and litigation.

We represent our clients at all levels of the EPO and before the UK Intellectual Property Office. Our team of litigators also has experience representing clients before the Intellectual Property Enterprise Court (IPEC), the High Court, the Court of Appeal and the UK Supreme Court, as well as having experience before US and Canadian courts.
