Emma Demetriades


Emma is a Partner in the Life Sciences team and her work focuses exclusively on the pharmaceutical sector. Emma manages patent portfolios covering a wide range of different subject-matter within the pharmaceutical field including new chemical entities, medical uses, dosage regimens, manufacturing methods, new formulations, and polymorphs. Emma works for some of the largest pharmaceutical companies in the world, helping them to obtain patents protecting their most successful and commercially important medicinal products.

Emma has significant experience in advising clients on all aspects of European patent prosecution but the majority of her time is spent assisting clients in defending their most valuable patents in post-grant opposition and appeal proceedings before the EPO. Emma has worked on some of the biggest multi-party oppositions at the EPO involving more than ten different opponents and has represented clients at oral proceedings before both the Opposition Divisions and the Boards of Appeal.

In addition to her significant experience before the EPO, Emma works closely with our in-house Dispute Resolution team on several litigation projects, co-ordinating response strategies before the EPO and across Europe to ensure a consistent approach is adopted in all jurisdictions, whilst tailoring the submissions and amendment strategies to meet the individual needs of each local court. Emma also works closely with technical experts during the litigation proceedings drawing on her chemistry background to get to the bottom of the science behind the invention and assist experts with the preparation of their written reports.

Emma joined Carpmaels & Ransford in 2010 after graduating from Pembroke College, University of Oxford that same year with a MChem in Chemistry. Emma qualified as both a UK Patent Attorney and European Patent Attorney in 2014.
