Chambers Review
Kirkland & Ellis has an expert team for revocation and infringement disputes with impressive command of second medical use and standard-essential patents. It has a particularly strong focus on the life sciences sector, regularly acting for medical device, biotech and pharmaceutical companies. The team is also highly recommended for electronics patent litigation, and is often called on to advise on non-contentious IP matters.
