UK prosecution firm Marks & Clerk is focused on, and known for, patent work in France. It has a staff of 26 attorneys in its sole French office in Paris, and 95% of work is on patents while only 5% covers trade marks. It is known for its high output and is one of the country's top PCT filers. It launched a new consultancy business in 2012, Marks & Clerk Consulting SNC, which provides IP advisory services, such as valuations of intellectual property, IP royalty audits and patent scoring. Aerospace, IT and defence are some of the firm's specialities. It represents Thales Alenia Space, Movea, Cooltech, France Brevets and Solsia.
The firm's joint managing partner, Christian Nguyen-Van-Yen, takes an active role in its work. In 2012 he was busy with several pieces of transactional work. He assisted a patent investment fund with its licensing and also advised Cooltech on a joint development agreement to use a new refrigeration technology.
Clients value the breadth of the firm's expertise. "It has the capability to handle any type of IP problem, not just filing patents but whatever IP question we have."
