James A. Stones


Expertise and Experience

James specialises in the chemical, pharmaceutical and medical sectors.  His chemical practice focuses mainly on “green energy” including oxyfuel combustion, synthesis gas production, fuel cells and carbon dioxide sequestration, but he also has extensive experience in the fields of gas separation by adsorption and cryogenic distillation, deposition techniques for forming semiconductor wafers, and polymers for many different purposes.  In the pharmaceutical field, his work includes new therapies for cardiovascular and metabolic disorders and GI-related indications, together with new techniques for the site specific delivery of drugs.  James’ experience also extends to implantable medical devices and packaged gases.

James undertakes original drafting work for a number of clients based overseas as well as for UK clients.  He is experienced in prosecuting applications through patent offices worldwide, and has an enviable record of success at the EPO in opposition and appeal proceedings.

James has worked on projects for both innovator and generics companies, and has worked with the full range of clients from individuals to multinational companies. He enjoys being involved from the creation of an idea to the launch of the product, and has undertaken “invention harvesting” where client projects are reviewed to extract potentially patentable subject matter. James provides detailed and commercially-focused advice on patent strategy and freedom to operate.

James is also a visiting lecturer at UCL School of Pharmacy on their MSc course entitled “Pharmaceutical formulation and entrepreneurship” where he lectures on the IP aspects of setting up a new pharmaceutical business.

At Beck Greener, James is the partner responsible for the Corporate Social Responsibility (CSR) function.  As part of the “greener Beck Greener” project, James has introduced a number of environmental initiatives intended to reduce the carbon footprint of the firm.  These initiatives have been recognised by the Camden Climate Change Alliance with the award of the “Cutting Carbon” and “Team Green” marks of achievement. He is also overseeing implementation of a schools project to promote careers in science, technology, engineering and maths (STEM) in general and in the IP profession in particular and to this end has become a STEM Ambassador with our community partner, STEM Learning UK. 


James is recommended for patents in The Legal 500 UK 2022 edition.  The Legal 500 says “James whose expertise includes EPO and USPTO patent prosecution, heads the chemical, pharma and chemical engineering team”.  In 2020 clients stated that "James Stones always goes beyond the call of duty. James understands the science behind our work and has a great success rate at opposition hearings because he is always very well prepared. I feel reassured when James is handling our patent oppositions and trust that the outcome will be as desired because he has consistently won cases for us. He is more than just a patent attorney; he is a business adviser to our company".  Other testimonials within the guide note that "James Stones is highly skilled technically and legally - diligent, detail-oriented, and a pleasure to work with".

In 2019 James was noted as being "knowledgeable", "incisive", "to-the-point" and "extremely effective".

James was singled out in The Legal 500 2017 for his "brilliant presentation at oral hearings" and noted for having "a deep understanding of pharmaceutical technology and patent law", which enables him to "negotiate complex patent issues effectively".

James was commended as "an exemplary and gifted lawyer who can think on his feet".
