Ellie Garrigan Mattar

Trainee Patent Attorney

Background

Ellie joined the Dehns London office in September 2024,  having obtained an integrated master’s degree in Chemistry that same year from the University of Oxford. Her final year thesis concerned the synthesis of self-assembled monolayers to be used as the hole transport layers of photovoltaic devices, and the fabrication of both organic and perovskite solar cells to test their function.

 

Types of clients and client work

Ellie works with clients of a variety of sizes, from small and medium-sized technology companies to multinational corporations with international patent portfolios.  She has experience working in multiple jurisdictions, such as the EPO, the UK, the US, China, the Republic of Korea, Japan, and India.  Most of her work concerns prosecuting patents internationally and handling oppositions and appeal procedures before the EPO.

 

Expertise

Most of Ellie’s professional experience involves work in the field of polymer chemistry.  This includes process chemistry for the production of polymers, including down-stream processes such as moulding or extrusion of polymer compositions.  She also has experience in the field of composite materials, with an emphasis on use of recycled materials. Ellie also works on coating technologies, primarily antifouling and intumescent coatings. She also has experience in pharmaceutical fields.

 

Qualifications and Memberships

  • Postgraduate Certificate in Intellectual Property Law, Bournemouth University, 2025
  • Student Member of the Chartered Institute of Patent Attorneys (CIPA)

 

Higher Education

MChem, Integrated Master’s degree in Chemistry, University of Oxford, 2024

Master’s (final year project) on ‘Investigation of carbazole derivatives for the hole transfer layer of photovoltaic devices’. In this thesis, Ellie synthesised small organic molecules which would form self-assembled monolayers (SAMs) when deposited on a substrate. These could then function as the hole transfer layers (HTL) in both organic and perovskite solar cells. Ellie also fabricated organic solar cells to test the function of these HTLs.
