Lauri Laatunen

Senior Associate, Member of the Finnish Bar

I advise our domestic and international clients on a wide range of technology, data protection, intellectual property and contract law matters.

Besides drafting and negotiating contracts across a wide range of industries, I regularly advise our clients on various contract law questions ranging from M&A-related advisory to resolving contractual disruptions. My expertise also covers advising on questions concerning a variety of regulated industries, such as consumer protection, product and food safety.

Over the years I have worked especially with clients in the technology sector and automotive industry as well as inspection and consultancy companies.

Prior to joining Castrén & Snellman, I worked as a trainee on technology and intellectual property matters at a major Nordic law firm, at a Big Four audit firm and a law firm specialising in complex IT procurement and data protection.

In addition to my Master of Laws degree from the University of Helsinki, I have studied law in Belgium at KU Leuven, which has been ranked among the world’s best law schools.
