My practice is concentrated in patent matters, mostly in the biotechnology and pharmaceuticals fields, but also in chemistry and mechanical matters. I have provided written and verbal advocacy at opposition and appeal levels at the EPO, before the UKIPO and before the English High Court. I am skilled at protecting clients’ IP assets from third party attacks, and clearing the way for freedom to operate by going on the offensive, and I have an enviable track record on both sides. I act most frequently for clients ranging from universities and spin-outs to multinational companies. My work brings me into contact with inventors, lawyers, tech transfer professionals and company executives. I am used to tailoring my advice to the background, experience and knowledge of my clients.Most of my contentious work is in oppositions and appeals at the EPO. I have led clients in attack and defence of patents for over 16 years and have attended hundreds of hearings. I have been involved in some of the largest cases at the EPO and have appeared before the Enlarged Board of Appeal. I also regularly provide infringement, validity and freedom to operate opinions. Additionally, I have an active practice in drafting and prosecution, and I am often asked to handle very complex matters where refusal is looking likely. Helping clients to turn such cases around is a source of great satisfaction for me.My work has encompassed technologies including:• CRISPR• engineered antibodies and other biologics• vaccines for infectious diseases and cancer• diagnostic methods, kits and devices• DNA sequencing• personalised medicine and companion diagnostics• nucleic acid array technology• medical devices • pharmaceuticals• microfluidics• polymers• cement compositions• various mechanical inventionsThe rapidly growing personalised medicine and genetic diagnostics fields are of particular interest to me, not least because of the peculiar ethical and patentability issues that they raise.
