Dispute Resolution & Litigation

Contentious enforcement and litigation

Our patent, trade mark and design rights attorneys are accomplished at protecting the interests of businesses during disputes. Attacking, defending or enforcing IP rights is not only about whether you win, but also whether the outcome is right for you commercially. We have a strong track record of defending our clients interests, proactively mitigating risk, and delivering results.

We are experts at navigating the UK and European IP systems and can advise on the best forum for any contentious matter.

Our patent and trade mark teams have significant experience in opposition proceedings at the UKIPO, EPO, and EUIPO and infringement and revocation actions at the UK courts and can steer you through the various stages, including when to commence legal proceedings, negotiation and resolution.

Whatever infringement, dispute or risk your IP encounters, and wherever you face it, Barker Brettell will help resolve the problem.

Please get in touch with Yvonne Johnson if you would like to chat about how we can support your team with our dispute resolution, contentious enforcement or oppositions and appeals resources:

“Commercially pragmatic advice and responsive. They take the time to fully understand our client’s business models and needs”
