Liz Cohen

Partner

With almost 20 years’ experience, Liz is a sought after adviser for pharmaceutical, biotech and medical devices companies alike and has represented companies in the life sciences industry in patent matters in the English Courts all the way up to the Supreme Court. Her extensive experience of coordinating cross-border litigation within Europe and beyond means that her strategic advice is particularly valued making her a trusted commercial adviser to her many clients.

Liz is a qualified solicitor advocate, a qualification she has used successfully to obtain an interim injunction on short notice in the High Court.

Liz’s background in natural sciences provides her with an excellent understanding of the technical and commercial issues facing those operating in the life sciences industry. Liz regularly advises clients on the implications of the proposed Unitary Patent and the Unified Patent Court and played an integral part in representing the alleged infringer in the much publicised Bristows UPC real-time mock action.

Liz’s work is regularly published in industry journals. She is also a member of EPLAW, EPLIT, and CIPA, and sits on the CIPA Life Sciences Committee.

She is frequently asked to comment and lecture on legal issues affecting the life sciences sector and she is a regular speaker at international conferences on strategic considerations for European and international patent litigation. Liz is a tutor on the Oxford University Diploma in Intellectual Property law and Practice course, teaching patent litigation.
