Patentwerk – Netherlands 2020

JUVE Comment

With only eleven patent attorneys, Patentwerk is the smallest of the major Dutch patent attorney firms. It is known in the market for its patent filing work, but also has a renowned litigator in Bas Langenhuijsen. Dutch law firms often bring him in for disputes over chemical and especially mechanical patents. Patentwerk is less visible in big-ticket litigation for major industrial corporates; it is recommended rather for its work for SMEs and venture capital investors.
