Matheson LLP has appointed Charleen O’Keeffe as a partner in its Disputes and Investigations Department. Charleen will lead its Intellectual Property (IP) Litigation Group, strengthening the firm’s existing offering in IP and regulatory law.
Charleen’s practice spans the full spectrum of IP law, including patents, trade marks, copyright, designs, and confidential information. She is a recognised leader in the life sciences sector, with a particular expertise in the intersection of regulatory law, competition law and patent litigation.
She works with wide range of national and multinational clients from global life sciences and healthcare companies to leading consumer goods companies.

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.”
