Nicolas du Teilleul


Nicolas du Teilleul offers strategic advice and can assist clients at all stage of a dispute on all aspects of intellectual property and unfair competition issues.

Over the years, he has developed an in-depth expertise and a strong reputation in transactional matters: negotiating and drafting contracts (license, assignment, coexistence, transaction, pledge, etc.), carrying out complex due diligence, developing and implementing intellectual property policies in the context of financial transactions (M&A, PE and LBO) with underlying IP issues. Furthermore, Nicolas represents well-known artists in the visual and performing arts (street artists, tattoo artists), as well as architects and corporate clients before the French civil and commercial jurisdictions and intellectual property offices in Europe.

Prior to becoming a lawyer, Nicolas worked both in France and in the United States for a sovereign investment fund (France Brevets) on technological development and patent licensing matters. Subsequently, he joined Gide for four years and then spent a year at Armengaud-Guerlain, two top tiers law firms in intellectual property, before becoming Counsel at D’Ornano + Co, a firm specialized in legal and financial due diligence. After setting up his own firm with an associate, Nicolas decided to join Squair as a partner in order to better co-ordinate and serve his clients needs and facilitate wider work.

Nicolas holds a Master 2 from C.E.I.P.I. (Center for International Intellectual Property Studies) and an LL.M. (Queen Mary University of London). He is a member of the L.E.S. France (Licensing Executives Society), for which he regularly speaks (Munich, Paris), and was the co-organizer of the 1st Pan-American Young Member Congress in Chicago. He also acts as an advisor for HEC incubators, and was ranked in the Legal500 (2019 and 2020).
