Testimonials

2026

"Very responsive, accurate and strategic approach, very good knowledge of the law and of the stakeholders, very nice to work with."

"HRM Belgium is one of the top practices in the Belgian patent litigation market.  The size and breadth of the team is excellent and the range of cases the firm gets involved is astonishing.  The firm is great value for money and has diverse set of lawyers.  The lawyers are also great to work with which is important when you are spending a lot of time together on large complex cases.
Another unique attribute about HRM is that they can staff lawyers cross-border for larger projects which can be very helpful when certain lawyers are under pressure from different cases.  It also has a number of female associates and partners with good DE&I records."

"We worked with HRM’s advisory service in relation to regulatory matters and pharmaceutical tendering and the team has been excellent.  Liesbeth Weynants and the team has been able to achieve a successful outcome on cease-and-desist based on clustering, likely to be the first in Belgium."

Liesbeth Weynants
