Matheson managing partner, Darren Maher, said: “Ireland continues to attract significant investment in technology and life sciences, and that is driving a steady increase in complex intellectual property and regulatory disputes. Clients need advice that is both technically strong and commercially grounded.”

“Charleen is widely recognised as a leader in intellectual property litigation and brings deep experience of high-value, multi-jurisdictional matters. Her appointment strengthens our ability to support clients operating at the centre of innovation, particularly where intellectual property, regulation and competition intersect. I am very pleased to welcome her to the firm and look forward to the contribution she will make to our clients and to the continued growth of our intellectual property practice.”
