The Patent 1000 focuses exclusively on patent practice and has firmly established itself as the definitive 'go-to' resource for those seeking world-class legal patent expertise.

Highly recommended - Individuals: prosecution

As one of the United Kingdom’s foremost patent attorney outfits, Kilburn & Strode ably serves players in virtually every sector, thanks to the depth and breadth of the expertise on show. Its three practice groups – tech, engineering, and life sciences and chemistry – are equal in stature, meaning that whatever the technical nature of an issue, the quality of service remains high. In addition, the group has been one of the strongest when it comes to adapting to the changes brought on by the pandemic – its working practices were already forward thinking before 2020, so hybrid working has not presented a challenge. Setting the standard is managing partner Richard Howson, who brings industry experience as a mechanical engineer to his patent practice. He has been defending a major aerospace player at the EPO for almost 15 years and is looked to for his creative solutions in the face of tricky challenges. His fellow engineer is Jim Miller, who similarly has hands-on experience – from his time working within BAE Systems. He received the CIPA Drafting Prize for the highest mark in the United Kingdom in the patent drafting exam, and in the years since his qualification, he has kept up this level of quality. For high-technology issues, Gwilym Roberts and Alexander Korenberg have both received acclaim. Roberts is named by many as the most famous patent attorney in Europe and his reputation does not seem set to change: “His knowledge of patent law and his patent prosecution skills are second to none, but what truly sets Gwilym apart is his understanding of our business and the level of customer service that he provides.” AI expert Korenberg is highly valued by his US patrons: “He is responsible for our European prosecution and provides insightful advice on effectively moving cases forward in Europe. Even given the time difference, Alexander always makes time for us when it comes to advising on patent strategy in Europe. He is a valuable asset to our team.” Meanwhile, in the life sciences and chemistry squad, Nick Lee, Nick Bassil, Elizabeth Crooks, Jennifer Harris and Tom Leonard can be found. Lee heads the team and works with both biotechnology and medical devices clients, bringing specific expertise in the T cell niche, while Bassil has almost 30 years’ experience building filing strategies for blockbuster pharmaceutical products, and continues to receive rave reviews: “Nick Bassil is a real expert when it comes to patent filing and strategy, particularly in the biotechnology and pharmaceutical sectors. His calm and thoughtful advice oozes confidence and genuine expertise and experience. He is very easy and reliable to work with.” Crooks is a force of nature in opposition proceedings before the EPO and specialises in industrial chemistry and consumer products, while chemistry lead Harris focuses on pharmaceuticals – her clients range from start-ups to multinationals and she ably handles the entire patent lifecycle. Leonard is an antibody expert with a fast-growing practice, which sees him advise on extremely high-value products in an increasingly relevant area.
