‘Mathys & Squire’s life sciences and chemistry and IT, telecoms and engineering departments are among the most active and prestigious patent drafting and filing practices in the market. While the practice counts a high number of international corporations as its clients, it can also look back on a strong track record of prosecution work for start-ups and was appointed as a provider of intellectual property rights services for the North Eastern Universities Purchasing Consortium in 2018.’ Christopher Hamer (who 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”) and Martin MacLean (“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“) direct the life sciences and chemistry group, while Jane Clark and Ilya Kazi (who 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.”) direct the IT and electronics department. Paul Cozens is the head of the engineering practice and the Cambridge-based Alan MacDougall leads the telecoms group. Anna Gregson “is simply outstanding. Professional, pragmatic, approachable and always on hand for advice.” 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”. Sean Leach “is technically brilliant and even R&D folks, who are PhDs in their specialist areas, have commended his grasp of new technologies” and Craig Titmus “is highly knowledgeable and consistently meets incredibly tight deadlines”.

Further praise for the firm includes: “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. Their experience makes it easy to entrust them with patent filings for UK as well as for EPO matters.”
