JUVE Patent

NLO – Netherlands 2020

JUVE Comment

This patent attorney firm is active in the Dutch litigation market with highly regarded partners Harm van der Heijden and Hans Hutter. Both represent Nokia as co-defendant of KPN in a dispute with Assia over DSL technology. They work with lawyers from Bird & Bird on the case. Thanks largely to these two patent attorneys, NLO has an outstanding reputation for providing technical support in litigation concerning mobile communications and electronics patents. When it comes to pharmaceuticals and biotechnology disputes, however, Mari Korsten is the firm’s figurehead. NLO’s position at the top of the Dutch patent market is not only due to litigation, however. The firm is also respected for its patent filing work. Its number of patent attorneys makes NLO one of the largest practices in the Netherlands. Furthermore, the firm boasts a strong share of international work before the EPO, where it files a large number of patents on behalf of Samsung and Baidu. NLO’s work is on a par with major patent attorney firms in Germany and the UK.


Patent disputes conducted by patent attorneys regarding mobile communication and pharmaceuticals. Patent prosecution, especially in electronics.

European strategy

The patent attorney firm has two offices in the Belgium cities of Ghent and Mechelen. Unlike large patent filing practices from the Netherlands and the UK, NLO forgoes an office in Munich, but files many electronics patents at the EPO for Samsung and Baidu.
