Marks & Clerk is one of the UK’s largest, and longest established, intellectual property firms. Our expert teams of patent and trade mark attorneys and lawyers are wired directly into the UK’s innovation economies via our offices in London, Birmingham, Manchester, Oxford, Cambridge, Edinburgh, Glasgow and Aberdeen.

Our team provides a full-service IP offering, from the initial filing of IP, through to litigation and commercial exploitation. Having seen the benefits that our clients derive from our full-service model, a number of patent attorney firms have since sought to follow a similar approach by adding solicitors to their teams. However, our well-established and highly regarded litigation and commercial transactions practices continue to set us apart from other firms.
We are experts not only in intellectual property law, but also in the science and technology that underpins our clients’ businesses. Our ability to draw upon this specialist technical expertise, not just in the context of patent prosecution but also in the context of litigation and commercial transactions, enables us to provide clients with a level of service and reach unmatched by other firms.
