Catherine M. Jewell


Expertise and Experience
Catherine’s patent practice is in the chemical field.  She has worked with a wide variety of technologies during her time as a patent attorney, including energy applications such as photovoltaic systems, general organic chemistry, materials chemistry, ceramics and polymers, drug delivery systems such as self-assembling lipid-based formulations, and pharmaceutical chemistry.  Catherine has handled inventions ranging from veneered floor tiles to epoxidation processes, siloxanyl polymers, zeolites and graphene coatings.

Catherine has drafted and prosecuted patent applications for clients with diverse needs and budgets.  Catherine represents large multinationals in prosecution, opposition and appeals at the European Patent Office.  In addition, she has a number of smaller clients whom she has helped to develop their products from concept to market, including drafting and filing patent applications and advising on trade mark use and registration.

Catherine also practises in trade marks, her experience including advising on strategies for handling, extending and maintaining international portfolios of marks, conducting and advising on searches, and defending the brand through opposition proceedings and the negotiation and drafting of settlement agreements.  Catherine is qualified to practise as a trade mark attorney under the laws of both the United Kingdom and the Republic of Ireland, allowing her to continue to practise before the EUIPO in relation to European Union Trade Marks and Designs post-Brexit.

Catherine is part of the team responsible for the firm's CSR function. Over the next year the team will continue to focus on its workplace and community aspects, including the longer-term transformation from a fully office-based working environment to a hybrid model with home-working, and how this affects the implementation of the STEM: Branching Out project, intended to help raise the profile of the legal profession and to broaden the appeal of a career in IP.

Before joining the profession Catherine worked in solid-state and materials chemistry, concentrating on the synthesis of inorganic materials and manipulation of their structure and properties.  During her PhD she studied intercalated materials, while her post-doctoral research focused on potential hydrogen storage materials, particularly alkali metal compounds.

Catherine joined the firm in 2013 and joined the partnership in April 2018.
