Gold - Firms: prosecution

“Kilburn & Strode is a one-stop shop for reliable advice on IP-related matters. The firm’s attorneys have a great understanding of complex technologies and provide excellent counsel for obtaining broad protection in an expedient manner. Furthermore, they are responsive, a pleasure to work with and always willing to take a call or answer some esoteric question of law. They are consistent across the board and very much serve as extensions of in-house teams.” Managing partner Richard Howson maintains a busy tech practice, drawing on over 20 years’ experience in the patent profession to keep his clients in the aerospace, automotive, and mechanical and electrical engineering sectors coming back. Under his leadership, the patent prosecution offering includes a life sciences and chemistry group, headed by Nick Lee, and the tech team under Gareth Fennell. Patrons write: “Gareth provides valuable and insightful advice on IP strategy and legal counselling on all IP-related documents. He is enthusiastic about technological innovation and an absolute pleasure to work with. He combines expertise and experience with the ability to understand the requirements and constraints of his clients. Gareth and the Kilburn & Strode team deserve the highest recommendation.” Other leading practitioners on the tech and engineering side include Tom HamerAlexander KorenbergGwilym Roberts and Jeremy Smith. “Tom is highly knowledgeable about EP and UK law, and the medical device technology field, including still-evolving questions about artificial intelligence (AI) in imaging, treatment planning, and other aspects of radiation oncology. He is a highly skilled and competent portfolio manager. Tom is a go-to provider for patent services.” Korenberg’s technical prowess extends from AI through life science devices, and he regularly works at the intersection of these areas. For instance, he has supported work for Sensyne Health Group, a UK-based clinical artificial intelligence company that uses data for the purposes of medical research. “Gwilym is a lawyer of choice for all IP matters in Europe, mostly patent, but also some trademark and unfair competition. His knowledge of patent law and his patent prosecution skills are second to none, but what truly sets Gwilym apart is his understanding of patrons’ businesses and the level of customer service that he provides. Gwilym is a true partner and friend to his clientele – as pleasant over a patent application as he is over a drink.” Smith has an ear for delivering patent applications at the perfect pitch. “He has a good pulse for meaningfully assessing subject-matter eligibility in Europe. He has no problem managing a vast docket of pending applications. He gets things right quickly and efficiently. The quality and timeliness of Jeremy’s work is top notch.” Newly promoted partner Caelia Bryn-Jacobsen has 25 years’ experience in the patent profession. A physics and tech expert with a strong reputation at the EPO, she deftly manages portfolios for femcare innovator Daye Limited, e-commerce disrupter Ubamarket, and supports the team for LG Display. Her contentious expertise was on display in her deflection of an EPO opposition launched by EOS GmbH against aerospace giant Boeing. On the chemical and life sciences side, Lee brings over three decades’ experience to his supervision of the practice, personally taking on work in biotech and medical devices. He is an astute operator in the field of immunology, especially the T-cell sphere. He acted for an anonymous entity to revoke Cellectis’s patent relating to CAR T cells for allogeneic transplantation. Lee is joined on the life sciences and chemistry team by Nick BassilJo Bradley, Elizabeth CrooksJennifer Harris and Tom Leonard. Bassil is a major pharmaceutical heavy-hitter, delivering top-notch patent work in the life science and chemistry field for 30 years. In the past year he has been active seeking an SPC for Melinta Therapeutics, as well as offering due diligence to Oxford Biomedica as it creates US subsidiary Oxford Biomedica Solutions. “Jo’s filing, prosecution and strategic advice is consistently excellent. Her ability to understand a university’s patent-related drivers is impressive. Jo also has an enviable ability to work with a range of leading academics. Her support is always timely and incisive.” Crooks boasts vast technical expertise in the chemical field, from industrial through consumer applications. Alongside her easy familiarity with drafting in that sphere, Crooks is also an accomplished hand at EPO oppositions and took on 12 hearings over 2021. Names she has represented there include Honeywell, Ball Corporation and AdvanSix Resins & Chemicals. “Jennifer delivers clear and reliable advice. Discussions with her invariably add value and often lead to an improved strategy. Jennifer shows particular strength in delivering comprehensive patent strategies to ensure across-the-border protection. She has a keen tactical eye.” “Tom is a superb attorney and his attention to detail is second to none. He is always available day and night and is a technical expert. Tom is first-class in the biopharm space, extremely diligent and very hardworking. He is also friendly, emotionally intelligent and highly considerate of others.”
