PATMA: Patent attorneys Tier 1

Mewburn Ellis LLP continues to thrive, with significant growth across all teams. The life sciences practice in particular has handled patents in biologics, bioinformatics, cell therapies, vaccines and precision medicines. The additional expertise in pharma regulatory matters and patent extensions as well as plant variety patents is another stand-out strength. On the chemistry side, the practice impresses with its work in advanced materials and polymers, and is an affiliate partner to the Graphene Engineering Innovation Centre. The engineering and ITC specialists offer combined expertise in patent and design work. At the EPO, the team is among the most active representatives in oppositions and appeals, especially when acting for defendants. Able to manage global IP portfolios of multinationals, but also excelling in original drafting work for smaller clients including prestigious universities, technology transfer offices and spun out start-ups, the firm offers a comprehensive patent prosecution package. In addition to its four UK offices, the firm also has an office in Munich, allowing for direct filing of German patents. Graeme Moore (Manchester) directs the engineering and ICT team, Jeremy Webster (Manchester) heads up the chemistry practice, and Simon Kiddle (Bristol) leads the life sciences team. The London-based Calum McGuinn, who specialises in chemistry and materials, made partner in April 2021. The previous April June Lyons (Manchester) and Susie Harrison (Cambridge) made patent director, a non-equity partner-level position. Patent director Rachel Jones left the firm in spring 2021.

Testimonials

This practice has deep expertise in the biotechnology industry and is experienced in the unique IP challenges and related business and legal risks present in the field. We are able to trust them with the company’s IP because they are not just a law firm, but a business partner who has their client’s best interest at heart, and who performs beyond the expected.

The people are proactive, helpful and eager to assist on giving appropriate advice or suggesting other companies when they are not sufficiently experienced to deal with certain areas. They are continually adapting the client database to match the needs of the client.  They do not instigate costly work if not necessary and will instruct on the estimated costs of any major work.  They have a diverse team to assist with specialised areas when required.

Richard Clegg is very astute and gives carefully considered advice that is pertinent to the issue at hand. He has a wide breadth of knowledge and experience on IP and related business and legal matters that can be relied upon.

Emma Graham always works in every way for our interest and seeks support for us, whenever needed, from others in her firm.

Katherine Green is very dedicated to deliver the best possible position for her clients. She can digs into every detail but keeps the big picture at the same time – very impressive!

Simon Kremer understands our work fully and can probe us on any new material. He is also able to oversee the consistent approach in our intellectual property portfolio.
