Expertise and professional education

Dr. Matthias Lachenmann specializes in advising on Technology and Data Protection Law, in particular with a focus on data protection for international groups, employee data protection as well as Industry 4.0/Smart Factory. Due to his industry focus on digital business/marketing, fashion and manufacturing companies, he primarily advises on data protection law aspects, such as IoT, AI, autonomous systems and GDPR implementation. Furthermore, he is active in litigating and defending companies in data protection proceedings (e.g., Rights of Access to data, civil enforcement of data protection claims, communication with supervisory authorities or fine proceedings). His clients include international corporations (in the Fortune 500 and Fortune 2000), German mid-sized companies with a global focus, and data-driven SMEs. He is regularly named in rankings as a leading lawyer in data protection law, most recently named in Wirtschaftswoche 2020 as a “TOP lawyer in data protection law” and 2021 in Handelsblatt/Best Lawyers as one of “Germany’s best lawyers”. Furthermore, he is Co-Chair of the privacy organization IAPP Chapter Rhein-Ruhr in 2022/23 and member of the scientific advisory council of the German privacy law magazine „Zeitschrift für Datenschutz“ (ZD).
Dr. Lachenmann studied law in Augsburg, completed his training in Frankfurt a.M. and Milan and received his doctorate under Prof. Dr. Jürgen Taeger at the University of Oldenburg on “Data Transmission within Groups”. He regularly lectures at (inter)national conferences and training courses on data protection law, e.g. at the CodeBlue Conference in Tokyo 2019. He is also a lecturer in the training of specialist lawyers for IT and labour law at the publishing house Dr. Otto Schmidt and in the training of Data Protection Officers at UDIS Ulmer Gesellschaft für Datenschutz und IT-Sicherheit gGmbH. He publishes continuously on data protection, e.g. in the book “Work 4.0”, in a commentary on German and EU ePrivacy laws and is known nationwide as the editor of the “Formularhandbuch Datenschutzrecht” (form manual on data protection law) at the publishing house C.H. Beck.
