7, Rue Joseph Stevens
Brussels, B - 1000

Jan-Diederik Lindemans is a partner in Crowell & Moring's Brussels office. His practice focuses on intellectual property, trade secrets, and entertainment law. Although Jan-Diederik assists a wide variety of clients in predominantly contentious matters, the core of his clients range from the chemical, pharmaceutical, and biotechnological sectors to the advertising, media, entertainment, and fashion industries.

Matters for clients active in the chemical and biotechnological industries are mainly (pre-)contentious and include the filing of protective letters (Schutzschrifte); third party opposition proceedings against counterfeit search and seizures; patent litigation with regard to the invalidity; and/or non-infringement of patents in sectors as life sciences, data exchange platforms, and powder milk.

Jan-Diederik's work for advertising and marketing agencies includes the protecting and/or clearing of promotional campaigns and concepts. In doing so, Jan-Diederik has built deep  experience in licensing (buying or selling) material that is protected by intellectual property (copyright, trademark, etc.) or personality (personal portrayal, etc.) rights. His experience in this area of the law has also persuaded other types of clients, such as photographers, graphic artists, and designers to have their often technical and industry specific legal matters handled by Jan-Diederik.

Clients in the media and entertainment industry generally call upon Jan-Diederik for assistance in negotiations and/or litigation against diverse entities active in this industry, in particular for matters relating to on- and off-screen talent, content production and licensing, and collecting societies.

Clients active in the fashion industry include manufacturers of luxury and leisure clothing, footwear, jewelry, and fabrics. Jan-Diederik has defended their interests in non-contentious matters relating to IP-portfolios, commercial disputes, distribution, counterfeiting, search and seizures, and EU-wide or national border measures.
