Kathryn Eldridge

Director | Patent Attorney

Kathryn joined Greaves Brewster in 2022 as a Director. She is a Chartered UK and European Patent Attorney and started her career at another private practice firm. She has a Masters degree in Chemistry from the University of Bath. She is capable of handling all areas of Chemistry, but specialises in Industrial Chemistry.

Kathryn has extensive experience in a variety of contentious matters including Opposition and Appeal proceedings before the EPO. She is comfortable handling complex cases with multiple parties, high value commercial products and nuanced legal issues, and maintains a high success rate. She also regularly advises on Freedom-To-Operate projects for commercial products, primarily within the field of industrial chemistry (including refrigerants, foam blowing agents, fire extinguishants, solvents and propellants). Other areas of interest include batteries and fuel cells, large scale synthetic processes, as well as catalysts and polymers.

Clients value Kathryn’s diligent approach and no-nonsense advice and have entrusted her to coordinate the defense of various challenges in Japan, China, South Korea and India, advise on pan-European litigation as well as submissions for PTAB trials before the USPTO.

In addition to her contentious skills, Kathryn brings a wealth of knowledge in the areas of IP audit and capture, IP filing strategies and global patent portfolio management. She is comfortable acting for a range of clients including individuals, SMEs, Universities, and spin outs through to multi-nationals. Kathryn enjoys building relationships with her clients so that she can provide valuable, strategic IP advice which fits with her client’s business plans.

Kathryn has a passion for Diversity & Inclusion, with a particular focus on gender, race and LGBTQIA+ issues, and has hosted many panels and events on the subject.
