Mireille Buydens heads the Intellectual Property and IT Practice at Janson Baugniet with Hans Dhondt. She is particularly recognised for her expertise in the field of patents, trademarks and copyright, with extensive experience in complex IP transactions.

She ranks amongst the leading IP lawyers in Belgium and she regularly acts for international chemical and oil companies, as well as major multinationals in the food sector. Mireille is highly regarded for her advice and is also well known for her litigating experience and skills.

Mireille is a professor at the University of Brussels, where she teaches IP law and information law, and a lecturer at the CEIPI (Centre d’Études Internationales de la Propriété Intellectuelle). She is the author or co-author of several books on IP, member of Belgian Council for Intellectual Property, member of the advisory committee of the Prof. Mr. E.A. van Nieuwenhoven Helbach Foundation and chair of the Belgian Examination Commission for Patent Attorneys.

She has a Law degree from the University of Brussels (ULB 1986) as well as a degree in Economic Law (ULB 1987) and a degree in Philosophy (ULB 1988). She also holds a Ph.D. in Law (ULB 1992) and a Ph.D. in Philosophy (ULB 1994).

Mireille was admitted to the Brussels Bar in 1992 and to the Paris Bar in 2001. After practising within other large Brussels and US business law firms, she joined Janson Baugniet as a Partner in 2013.

The team advises and assist clients in drafting and negotiating IP-related agreements, including licence agreements, research and development agreements (R&D), merchandising and sponsoring agreements, non-disclosure agreements (NDAs), assignment of technology and intellectual property securities.

Our expertise in the field of litigation is also widely recognised. We assist companies in collecting evidence of infringements of their rights (unilateral proceedings), defend their interest in legal proceedings and help them to obtain corrective measures (recall and destruction of products, compensation for damages). The team is also highly experienced in arbitration. The partners of the department are regularly appointed as ICC arbitrators in CEPANI proceedings.

Lastly, the team is also consulted for audits and due diligence in intellectual property, e.g. in connection with an acquisition.

Founded in 1950, Janson Baugniet is a multidisciplinary and multilingual business law firm, currently consisting of 30 partners and more than 60 associates, most of whom have an LL.M. or another university degree from Belgium or abroad alongside their degree in Law.

Throughout its expansion, Janson Baugniet has remained independent of other national or international law firms.

In 2004 the law firm Van Drooghenbroeck-Lagneaux, which specialises in social law, merged with Janson Baugniet. The pluralistic character of the law firm was strengthened with the opening of the Ghent office, enabling the team to offer a comprehensive service to its Flemish clientele.

The Favart firm, located in Mons and active since 1957, joined Janson Baugniet in 2017.

Several partners and senior associates teach at university law schools or elsewhere, or are members of editorial boards of one or more legal journals.

Janson Baugniet has extended its legal services to all fields of law relating to economic activities. The firm’s clients belong to different sectors of the economy, such as energy, real estate, communication, finance, the automobile industry, environment, health, etc.

The firm assists Belgian and foreign clients – both companies and individuals – as well as public authorities, funds and (international) non-profit associations.

“Co-head of the department Mireille Buydens continues to play a leading role in complex litigations, especially relating to unfair trade practices. One client describes her as “an impressive IP lawyer with an extraordinary knowledge of IP law in Belgium and also at the EU level.”
