Nicola Dagg

Nicola Dagg is widely regarded as one of the most influential intellectual property litigators in Europe, particularly in high-value patent disputes. 

As a senior partner at Kirkland & Ellis, she has built a reputation for leading complex, cross-border litigation for major multinational clients, especially in the life sciences and technology sectors. 

Her work regularly involves some of the most significant pharmaceutical, biotech and telecommunications disputes in the UK and across Europe, including matters relating to standard-essential patents and FRAND licensing, which are central to global technology markets. 

Dagg’s representative matters include acting as lead global counsel for Lenovo in its high-value patent/licensing dispute with InterDigital, and representing Pfizer as lead counsel in patent litigation against Amgen. 

Beyond individual cases, she is recognised for her role in shaping broader litigation strategy across multiple jurisdictions, often coordinating parallel proceedings and advising on global enforcement approaches. 

Consistently ranked in the top tier of intellectual property practitioners and included in leading industry recognitions, Dagg is a key figure in the development of modern patent litigation strategy.
