The team has a unique blend of diversity of technology expertise combined with individual personal touch, which means that you get both the security that the science is fully understood, along with the in-depth relationship with a single key legal adviser. They are adaptive and responsive to the client’s needs, and very experienced in handling complex collaborative projects with several stakeholders. They also have outstanding commercial expertise, so always see the bigger picture.

Mathys & Squire LLP is an excellent associate office for EPO patent matters. The team is efficient and responsive. They are in tune with the client’s needs and handle our requests in a professional and well-organised manner.

Very professional, innovative, reliable and efficient.

Very thorough in analysis, preparation and strategy for oppositions.

Anna Gregson is simply outstanding. Professional, pragmatic, approachable and always on hand for advice.

Martin MacLean is a real guru in the healthcare and pharmaceutical field, and brings his experience to bear in not only giving very wise legal advice, but also setting things in a commercial context.

Ilya Kazi is second to none in being able to sit down with a new client and get straight to the crux of the issue they need to resolve. He is excellent both in detail and in longer term strategy, very often coming up with business directions that the clients have not thought of.

Catherine Booth excels in: 1) understanding the business needs, 2) learning the technical details, 3) capturing relevant law, 4) persuasive communication both on paper and in person, 5) listening to and countering third parties in real time.

Christopher Hamer is always keen to provide support in whatever way the firm can, which is very useful for an in-house team that has several peaks of legal work and different priorities from time to time.

Sean Leach is technically brilliant and even R&D folks, who are PhDs in their specialist areas, have commended his grasp of new technologies.

‘Craig Titmus is highly knowledgeable and consistently meets incredibly tight deadlines.’
