To his clients, James Stones is “more than just a patent attorney; he is a business adviser.” The head of Chemistry, Pharmaceuticals and Chemical Engineering, he is widely admired for his “deep understanding of pharmaceutical technology and patent law."


A patent attorney who “always goes beyond the call of duty” for his clients, James focuses on the chemical, pharmaceuticals, medical and chemical engineering sectors, and has extensive experience in cryogenics, refrigeration, ‘green’ energy, medical devices and adhesives. With a “great success rate at opposition hearings,” his strength lies in the creation, management and defence of global patent portfolios for a range of high-profile companies.

As head of Chemistry, Pharmaceuticals and Chemical Engineering, James is especially well known for his experience in the pharmaceuticals and medical sectors. Here, his work includes new therapies for cardiovascular and metabolic disorders and GI-related indications, together with novel techniques for the site specific delivery of drugs, as well as implantable medical devices and packaged gases. His chemical practice is also extensive, and focuses mainly on sustainable energy technologies, including ‘green’ and ‘blue’ hydrogen production, oxyfuel combustion, synthesis gas production, and carbon capture and storage. Additionally, he has extensive experience in the fields of gas separation by adsorption and cryogenic distillation, polymers and adhesives.

James undertakes original drafting work for a wide range of international and domestic clients, from individuals to multinationals, including both innovator and generics companies. He prosecutes applications through patent offices worldwide and has an enviable record of success in opposition and appeal proceedings at the EPO. He enjoys being involved from the creation of an idea to the launch of the product, and regularly undertakes ‘invention harvesting,’ where clients’ projects are reviewed to extract potentially patentable subject matter.

James is also a visiting lecturer at the UCL School of Pharmacy, lecturing on the IP aspects of setting up a new pharmaceuticals business as part of its MSc course entitled ‘Pharmaceutical formulation and entrepreneurship’.

At Beck Greener, James is responsible for the Corporate Social Responsibility function, which has seen him introduce a number of successful environmental initiatives as part of the ‘greener Beck Greener’ project, to reduce the firm’s carbon footprint. He also oversees the firm’s award-winning outreach work in schools to promote careers in STEM and the IP profession. James is a STEM Ambassador with the firm’s community partner, STEM Learning UK, and an Ambassador with Heart of the City, a charitable organisation dedicated to helping SMEs implement sustainability and community-based projects.

“James Stones provides outstanding services. He is proactive, cost conscious, and highly competent, and he can explain patent-related issues in words that are understandable to the non-patent lawyer people.”


James is recommended in The Legal 500 UK 2024.
