Tjibbe Douma

I am a partner in the Intellectual Property Group based in Amsterdam, with a focus on technology-related matters, in particular patents and trade secrets.

I advise and litigate for clients in the life sciences, tech & comms, energy & utilities and retail and consumer sectors. I have extensive experience in both European and US litigation, including high-end multi-jurisdictional patent disputes.

I have acted for both opponents and patentees as co-counsel in EPO opposition proceedings. I have also represented clients in contractual disputes, including contractual litigation involving milestone claims in the life sciences sector and in arbitration proceedings regarding IP warranties.

I regularly advise clients on IP strategy and on technology-driven M&A deals including in the venture technology field.

My work has been recognised by rankings over the past years in Chambers Global & Europe, Who's Who Legal Patents & Life Sciences, IAM Patent 1000, MIP and in 2020 by receiving the Client Choice Award for Intellectual Property - Patents in the Netherlands.
