GSK Stockmann is primarily known for its IT and data protection-related advice and therefore enjoys a good reputation not only among established large companies, but also particularly among start-ups with digital business models. The practice further assists clients with counterfeiting, misleading advertising and greenwashing issues, for instance as demonstrated in its representation of Tesla against the Federal Consumer Center Association. Jörg Kahler focuses on technology and digitalisation projects and, in addition to competition law, also assists with trade mark, copyright and data protection matters; he jointly heads the practice with Katy Ritzmann, who counts a large number of start-ups among her client base and also advises on licensing agreements among other matters.
