Edward Oates


Ed practises in the life sciences field, with a particular focus on pharmaceuticals, from small molecule inventions through to later stage developments. He is a “very impressive life sciences specialist” (IAM Patent 1000) and has worked on numerous marketed products across a variety of fields, including some of the world’s most valuable medicines of recent times. Ed “has an enviable track record before the EPO” (IAM Patent 1000) and has been the lead defence advocate on some of the biggest multi-party oppositions to have taken place at the European Patent Office in the life sciences field, up against fourteen opponents for Novartis and fifteen opponents for Johnson & Johnson. Ed also has an exceptional experience in patent lifecycle management, advising clients on supplementary protection certificates (SPCs), paediatric extensions and regulatory exclusivities. He has an extremely detailed knowledge of SPC law, and has coordinated many complex pan-European SPC portfolios.

Ed has worked on some of the seminal SPC cases of recent years, and consequently has been invited on a number of occasions to address the annual meeting of pan-EU SPC examiners. Along with his “terrific prosecution and SPC experience” (Managing IP), Ed has acted before the Court of Justice of the European Union, the Court of Appeal of England and Wales, the High Court of England and Wales and the UK Intellectual Property Office, and has worked on litigations in a number of jurisdictions around the world.

When not engaged in contentious work or prosecuting patents, Ed uses his “very impressive … breadth of pharmaceuticals knowledge” (IAM Patent 1000), coupled with his experience on big-ticket cases, to provide his clients, within the life science sector, with practical advice in relation to IP matters. This includes freedom-to-operate advice and transactional support, such as due diligence.

Prior to joining Carpmaels & Ransford in 2003, Ed studied chemistry at University of Oxford where he was awarded a scholarship and a number of prizes for his academic performance, graduating with a first class degree. He spent a research year focusing on the organic synthesis of transition metal coordinated macrocycles. Ed then gained a distinction in the Certificate in Intellectual Property Law from Queen Mary College, University of London. After becoming a European and UK patent attorney, Ed qualified as a Patent Attorney Litigator, receiving the Hogarth prize as the highest-ranked patent attorney in his year.

"An original thinker" and "a very good advocate in the EPO." "He is a powerful intellect with great SPC knowledge."
