Cameron Marshall

Practice Areas

Cameron focuses exclusively on the biotechnology and pharmaceutical fields, with an extensive EPO opposition practice (including many cases defending against multiple opponents) that runs alongside a large prosecution practice. These two areas often overlap, so strategic prosecution and parent/divisional strategies are a regular part of his workload. He is often engaged to advise clients at an early stage, in situations where future patent fights with competitors are inevitable.

Cameron acts for biotech companies including Guardant Health and Mammoth Biosciences, but most of his time is spent acting for blue-chip pharmaceutical companies, including Novartis, Merck, Gilead, and Lilly. This work includes defending patents covering blockbuster products which have attracted numerous EPO oppositions, whether from traditional generics companies or from biosimilars. He often acts as lead counsel at the EPO, but also collaborates with other firms to provide a second pair of eyes, and frequently plays a support role for national litigations.

Career

Cameron has over 25 years of experience of inter partes proceedings at the EPO, both defending and attacking, and he is one of only a handful of attorneys to have represented a patentee in an EPO opposition (and subsequent appeal) involving more than 15 opponents. This experience means that he is often engaged to defend patents which provide crucial protection and exclusivity for blockbuster pharmaceuticals and biologics, including patents on new medical uses, dosing regimens, and formulations.
