Mark Deem
Position
Mark is a solicitor-advocate and thought leader in the digital and technology sector.
“I am passionate about working with my clients to protect their assets and supporting them in realising their goals at critical times in their commercial lives. I pride myself on finding creative solutions and make a point of getting to know and understand what is important to my clients and – perhaps crucially – what is not.
My practice focuses on helping optimisers and adopters of technology products and services, and disruptors using cutting-edge digital and technology solutions.
My recent book, AI on Trial (pub. Bloomsbury Professional) explores the present status of artificial intelligence and proposes a Manifesto for Responsible AI, a blueprint for any ethical, legal and regulatory framework for this transformative technology. I am also the editor of the Global Data Review Guide to Data as a Critical Asset.
I’ve conducted litigation in all commercial divisions of the English High Court, Court of Appeal, Supreme Court and Court of Justice of the EU; represented clients in international arbitration proceedings under the rules of the ICC, LCIA RIDR and IFTA; and have a broad experience of mediation and other dispute resolution mechanisms. Clients value my strategic advice and ability to manage exposure to the risk and cost of commercial disputes through innovative use of funding arrangements.
Away from work I live with my family in rural Cambridgeshire and enjoy playing piano, clarinet and saxophone, and performing in various ensembles.”
Mark is a widely regarded practitioner and is recognised as a “leading lawyer” and “highly rated adviser” by the main directories.
