Carpmaels & Ransford LLP

Anna’s area of expertise is in biotech. She has a current focus on cell therapy, and carries out European patent prosecution of a large portfolio of patent applications in this rapidly developing and complex field. Innovation in the cell therapy field comes in many forms, and in addition to this diverse field Anna also works with clients in many other technology areas. In particular she has extensive experience in the areas of protein therapeutics, diagnostics and platform technologies. She has worked with clients of all sizes and types to develop and execute their IP strategies. At all stages, she focuses on building effective working relationships to ensure that clients’ objectives are fully understood. She has extensive experience of drafting patent applications, as well as prosecuting these and other applications at the EPO, and coordinating global patent portfolio prosecution. Running alongside her drafting and prosecution work, is her advice and contentious work. She has considerable experience of oppositions and appeals at the EPO, and supports clients with a variety of advice, including freedom to operate analysis and due diligence exercises. The technical expertise that Anna acquired in her studies and during her time as a patent attorney means that irrespective of the specific technology, she is able to think creatively and solve problems. Anna always looks for the bigger picture, but without losing sight of the technical detail. Her first class degree in Biochemistry from the University of Oxford gave her a broad understanding of the biotechnology field and she built on this with a PhD from the University of London. Anna’s research in cell and developmental biology was carried out at the Imperial Cancer Research Fund (now Cancer Research UK) and focused on intracellular protein targeting and signalling in development, specifically looking at EGF receptor family members and their signalling and intracellular targeting in polarised epithelial cells. Anna entered the patent profession in 2000, and joined Carpmaels & Ransford in 2013 from another large UK firm. While training she was awarded the Bill Caro prize for overall first place in the Certificate in Intellectual Property Law examinations. Anna is an active member of the IPO’s Women in IP Committee, and is a co-chair of the “Mentoring Across Borders” subcommittee. This involves coordinating group and pairs mentoring programs, which brings together participants from across the globe. She also participates as a mentor in the Social Mobility Foundation’s mentoring program for A-level students. Within the firm she takes a particular interest in recruitment and in the training of technical assistants. She is fluent in French, having lived in France previously.

Bruce’s approach relies on attention to detail in order to deliver pragmatic advice to compliment his clients’ commercial interests. His work has garnered praise in the independent guides to the legal profession, having been recognised as ‘tenacious’ in the Legal 500 publication.

Cameron Marshall

Cameron focuses exclusively on the biotechnology and pharmaceutical fields, with an extensive EPO opposition practice (including many cases defending against multiple opponents) that runs alongside a large prosecution practice. These two areas often overlap, so strategic prosecution and parent/divisional strategies are a regular part of his workload. He is often engaged to advise clients at an early stage, in situations where future patent fights with competitors are inevitable. Cameron acts for biotech companies including Guardant Health and Mammoth Biosciences, but most of his time is spent acting for blue-chip pharmaceutical companies, including Novartis, Merck, Gilead, and Lilly. This work includes defending patents covering blockbuster products which have attracted numerous EPO oppositions, whether from traditional generics companies or from biosimilars. He often acts as lead counsel at the EPO, but also collaborates with other firms to provide a second pair of eyes, and frequently plays a support role for national litigations. Cameron has over 25 years of experience of inter partes proceedings at the EPO, both defending and attacking, and he is one of only a handful of attorneys to have represented a patentee in an EPO opposition (and subsequent appeal) involving more than 15 opponents. This experience means that he is often engaged to defend patents which provide crucial protection and exclusivity for blockbuster pharmaceuticals and biologics, including patents on new medical uses, dosing regimens, and formulations. In addition to that work, though, he also handles biotech innovations and has recently been defending Guardant’s groundbreaking work on liquid biopsy against several opponents. His biotech work goes back a long way, and he defended the “Southern” patents on DNA microarrays and spent two decades working on the inventions underpinning lifesaving meningococcal vaccines. The main independent guides to the legal profession regularly rank Cameron at the top of his field. He is recognised as a “highly experienced litigator” (JUVE 2023) with “great business acumen and a strategic mind” (Chambers & Partners). As well as advising on patent matters, he was a tutor for several years on the JDD residential course preparing candidates for the EQE opposition paper, and was an advisor to the IP monitoring group of the UK Government’s Human Genetics Commission. Cameron graduated from the University of Oxford where his work on the folding thermodynamics of fibronectin type III modules was awarded the university research prize and contributed to his first class degree.

Chris adopts an upbeat, ambitious and practical approach to his work, and is often called upon to advise on business-critical patent strategies, informed by his careful understanding of the objectives in view and his 30 years of experience in the industry. Notably, Chris defended Micron Technology’s synchronous DRAM business in Micron’s epic 13-year battle with Rambus, in which he successfully neutralized a series of European patents held by Rambus. These cases yielded valuable insights into a series of complex legal questions concerning the extent to which applicants for European patents can redefine the inventions for which they are seeking protection; subsequently, they have been used as a teaching resource by the EPO itself. Chris is a qualified litigator and has been deeply involved in patent litigation in all the English courts, including the Supreme Court, as well as in France, Germany and Italy. Chris enjoys applying the lessons learned from his extensive opposition practice and his involvement in litigation and is often called upon to engage with technologies outside his core practice where his insights have added significantly to the conduct of litigations and important opposition cases. Recent engagements have included forays into combination therapies and DNA sequencing. During his professional career, Chris has spent time serving on the Executive Committee of a major international law firm. He was a scholar of St. Peter’s College, University of Oxford, graduating with a first class degree in physics.
