Gillian McGuire (née Phillips)

Gill’s expertise is in pharmaceutical chemistry, in particular drafting, prosecuting and defending small molecule pharmaceutical cases, primarily for pharmaceutical originators. She has wide experience in the sector, advising the largest multi-national pharmaceutical companies, mid-caps and start-ups, including Janssen, Vertex and KalVista Pharmaceuticals. Gill advises a number of her clients on the management of global patent portfolios and has prosecution experience in the major global jurisdictions beyond Europe, including the US, Japan, China and Korea. Her experience advising on commercial products means she regularly handles the complex interplay between patents, supplementary protection certificates and regulatory data protection. Gill is a sought-out advisor for clients seeking to develop strategies for the management of global patent portfolios to protect commercial products.

Historically, Gill also has experience in the fields of polymer chemistry, industrial process chemistry, organometallic chemistry and materials. As with her pharmaceuticals work, these fields can be highly contentious in nature, and a large part of Gill’s portfolio involves handling opposition cases, in both attack and defence.

Gill’s work highlights her extensive experience in representing clients in both ex and inter partes hearings before the European Patent Office, most notably Dupont Teijin Films and Johnson & Johnson. She has also supported a number of pan-European patent litigations on commercial pharmaceutical formulations with lead responsibility for technical arguments.

Gill has first class MA (Hons) and MSci degrees in Natural Sciences from St. John’s College, University of Cambridge.
