Full Bio

Clients rely on Marcus for his specialisation in chemistry patent matters – primarily the drafting and prosecution of patent applications, oppositions, providing validity and infringement advice, and conducting ‘freedom to operate’ patent searches.  Clients regularly comment on the intellectual input that Marcus makes, noting that they consider him to be a trusted advisor and very strategic in all that he contributes.  Clients often mention the significant effort that Marcus invests to develop processes which help them ‘in house’ to manage their intellectual property, adding value and saving significant resources.

Specialising in patent matters related to all areas of chemistry, his main areas of expertise are in opposition and infringement opinions.  He has a vibrant patent opposition practice and has particular expertise in the gathering and interpretation of competitor intelligence, which he then integrates into a variety of strategic risk management services to his clients.  Over the past few years, Marcus has built a robust expertise working with multinational corporates to develop tailored competitor surveillance tools which assist them to actively monitor current market conditions.  He has assisted a variety of clients, including foreign corporates, individuals, universities, start-ups, and established large companies, to develop and enforce intellectual property rights relating to a variety of technologies, with a specific focus in chemistry.

Marcus has extensive experience in a diverse range of technologies including animal health products, polymer chemistry, organic chemistry, biochemistry, rational drug design and delivery, formulation chemistry, agrochemicals and analytical chemistry, nanotechnology (including nanofabrication, nanomaterials and nanodevices), and other emerging new technologies in the chemical area. He also has experience in mining and processing of coal and other mineral resources.
