Marcus’ technical expertise is in chemistry, and his cases span a wide range of technologies including catalysts, pharmaceuticals and food technology. He recently spent fifteen months on secondment to a multinational consumer goods company, where he gained significant in-house experience in relation to IP-related agreements, IP due diligence, and in planning and handling large freedom-to-operate projects.
