Eleanor Maciver

As sustainability champion at Mewburn Ellis, leading patent attorney Eleanor Maciver makes a marked contribution to the firm’s green transition journey, leading its environmental strategy and coordinating staff activity within its sustainability collaboration group. She is a thought leader on best practices surrounding law firms’ decarbonisation journeys, having written insights for the Legal Sustainability Alliance on the internal measures which best enable the delivery of its sustainability ambitions.

In her legal practice, Maciver supports emerging technology players in building their green products, specialising in how IP can be leveraged in the sustainable chemical and material inventions space to help create and scale-up sustainable polymers, nature-based materials, plant-based foods, battery materials, sustainable refrigerants, and carbon capture and storage.

As part of this expertise, Maciver coordinated the firm’s 2023 Green Channel report, which explored key trends and takeaways from the UK’s green IP pathways. As a thought leader in the cleantech and IP spaces, she has authored insights into topics including the European Patent Office’s cleantech commercialisation and financing report and delivered a green IP masterclass for the Royal Society of Chemistry.
