Colin Devinant's practice centers on national and international patent litigation. He has experience working on contentious and noncontentious matters in France and abroad (Germany, U.S., UK) for start-up and international groups involving patent rights across many technical fields (mechanics, chemistry, electronics, cosmetics, packaging, transports, consumer products, medical devices, agrochemical products, construction, biosimilars, generics).

Colin's primary focus is on patent validity and infringement litigation as well as on compensation for employee inventions and patent ownership claims. He also drafts and negotiates confidentiality, license, research, and technology transfer agreements and performs IP due diligence in support of M&A deals.

Prior to joining Jones Day in 2018, Colin practiced patent litigation in the Paris office of a U.S.-based international law firm and interned at a leading French patent litigation firm in Paris. His previous experience also includes serving as an intern in the IP legal department of a French research university, where he drafted and negotiated research and development (R&D) agreements, as well as for a French patent and trademark prosecution firm.

Colin has authored several publications discussing patent litigation, notably regarding software patents, generics, and the Unified Patent Court.

Colin is an active member of several of the main professional associations in IP: the International Association for the Protection of Intellectual Property (AIPPI) (member of the Executive Committee and of the Patents, UPC, and Young Members commissions), the Young EPLAW (European Lawyers), and the French Association for the Protection of Intellectual Property (AFPPI).

In 2024, he was ranked by The Legal 500 as a Rising Star in patent litigation.
