Rachel Mumby

Senior Associate

Rachel is a patent litigator with ten years’ experience in advising clients across a broad range of subject matters, from pharmaceuticals and medical devices to areas as diverse as mobile apps, glass fibres and beer dispensing machines. She has a particular interest in the chemical and life sciences sector due to her background in chemistry.

Rachel has worked on matters before the High Court, Court of Appeal and Supreme Court. She also has experience of obtaining interim injunctions, advising on complex damages matters and supporting EPO oppositions, as well as providing strategic patent opinions.

In addition to her practice in English patent litigation, Rachel also has extensive experience in the co-ordination of IP litigation relating to global pharmaceutical products. This involves managing litigation in a range of jurisdictions and she therefore regularly works closely with lawyers elsewhere in Europe and the USA.

Rachel spent seven months on secondment to the patent litigation team of a US biopharmaceutical company where she gained a first-hand appreciation of life as “the client” and a valuable insight into how best to provide good client service and useful, commercial advice.

Rachel co-ordinates a team of writers at Bristows for the EPLAW patent blog.
