Cameron Marshall focuses exclusively on the biotechnology and pharmaceutical fields and has an extensive prosecution and opposition practice involving regular trips to the European Patent Office (EPO) to represent clients. He has over 20 years' experience of inter partes proceedings at the EPO, both defending and attacking, and is one of only a handful of attorneys to have represented a patentee in an EPO opposition involving more than 15 opponents.
Although most of Mr Marshall’s work is in the biotechnology field, his experience in EPO oppositions means that he is often engaged to defend crucial protection for blockbuster pharmaceuticals, including patents on their formulations, salts, new indications and dosing regimens. This can be both as lead counsel at the EPO or in a support role for national litigations across the globe.
Most of Mr Marshall’s time is spent acting for global blue-chip pharmaceutical companies, but he has a varied caseload for many large and small clients from Europe and the United States.
Beyond the United Kingdom and the EPO, Mr Marshall has worked on re-examinations, interferences and arbitrations in the United States, and has coordinated parallel invalidity proceedings involving more than a dozen jurisdictions across six continents.
