Maggie Gisseleire

Senior Associate

Maggie works in the Pharmaceuticals and Chemistry groups at Carpmaels. She focuses primarily on healthcare and consumer technologies, including small-molecule drugs, antibody-drug conjugate therapies, hemostats, and polymeric products. Maggie advises clients through all stages of the patent process, from the drafting of new applications, to coordinating prosecution of global patent portfolios, through to post-grant contentious proceedings.

She particularly enjoys defending or opposing patents in opposition and appeal proceedings at the EPO, and has represented clients in a number of cases protecting their key commercial products at EPO hearings. Maggie also has valuable experience providing support for multi-jurisdictional patent litigation disputes, including helping handle enforcement actions and the defence of nullity actions across Europe.

Maggie works for both established multi-national companies and early-stage companies, and aims to develop robust and realistic IP strategies suitable for clients’ specific commercial objectives.

Maggie joined Carpmaels & Ransford in 2015, qualifying as a Chartered Patent Attorney in 2019. She graduated from the University of Cambridge with a degree in Natural Sciences (Chemistry), having studied a range of subjects across organic, physical and inorganic chemistry. She spent her final summer in the lab working on a fragment-based drug discovery approach to SMYD3, a methyl transferase epigenetic target.

Outside of the office, Maggie enjoys practicing yoga, attending a local book club, and trying her hand at wheel-thrown pottery. She is fluent in French, and likes to stay up to date through French cinema and podcasts.
