Pat has specialised in EU law and competition law for almost 30 years and has been involved in landmark cases at EU and national level.  In addition to her expertise across the range of competition law, she has particular strengths in advising on the complex legal and policy issues arising where competition law and intellectual property law intersect.  Consequently, clients in high technology sectors including life sciences and TMT seek her advice regularly.

Pat represents clients before the competition authorities and the courts, whilst also advising on competition law issues in complex agreements (including settlement, R&D and licensing agreements).  Pat advises many of the Firm's clients on the competition law responsibilities affecting dominant companies. She and her team assist clients with competition compliance programmes and preparation for "dawn raids", having supported clients through such dawn raids and their aftermath.  Pat is also a frequent commentator on the intersection of competition and IP law as featured in the blog The CLIP Board.

Pat is a member of the Competition Law Association; the UK Association of European Lawyers; and the Competition Section of the Law Society.  She is on the editorial board of the Journal of Intellectual Property Law and Practice and Competition Law Insight. Pat lectures and writes widely on topical issues. She also teaches the competition law module on the University of Oxford Postgraduate Diploma in Intellectual Property Law and Practice course.
