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.
