Harry Bush

Since joining Carpmaels & Ransford as a trainee in 2017, Harry has built up a wealth of experience through his work in the Chemistry team, with a focus on small molecule pharmaceuticals. He has advised on all aspects of the patent lifespan, including drafting new applications, devising and executing EPO opposition strategies, enforcing patents in global litigation actions, co-ordinating FTO and due diligence projects, and executing Europe‑wide SPC filing strategies.

Harry has accrued experience in the preparation and worldwide prosecution of patent applications, working directly with inventor teams and counsel at numerous clients. A particular focus has been drafting and prosecuting NCE applications covering small molecule compounds, building robust portfolios with polymorph, formulation, and new medical use applications as the compounds develop into clinical candidates.

He has gained a wealth of experience in EPO oppositions, having been part of teams defending against multi-party oppositions to patents covering marketed drugs, and successfully advocating for clients at oral proceedings before the EPO.

Before joining the firm, Harry studied Chemistry at Merton College, University of Oxford. He gained his passion for organic chemistry during his degree, which has provided the foundations necessary to support his clients. As part of his studies, he spent a year investigating site-specific oxidation of small molecule compounds using a library of Cytochrome P450 mutants.

Harry has co-ordinated the firm’s involvement with the Social Mobility Foundation (SMF). This has involved recruiting and supporting the firm’s cohort of mentors, who support secondary school students with advice about careers and education in their sectors of interest, as well as being a mentor himself to numerous secondary school students. Carpmaels & Ransford has also hosted SMF students on work placements, and Harry and other mentors have presented on panels relating to legal and science sector professions.

Away from the office, Harry is at his happiest on the ski slopes, but closer to home he loves making the most of London’s food scene and will seldom pass up a night at the opera, ballet or theatre.
