Prof. Dr. Thomas Höppner

Prof. Dr. Thomas Höppner is a Partner at Hausfeld, specialising in EU and German competition law and intellectual property law. His practice covers the full range of contentious and non-contentious competition law matters, including related regulatory areas such as media, telecommunications, broadcasting and energy.

He has spearheaded complaints before the European Commission and taken competition claims before German courts, particularly in the context of an abuse of dominance and damage claims. Thomas has particular expertise in technology, media and network industries where he regularly advises clients in complex proceedings and litigations at the interface of competition law, sector-specific regulation and intellectual property law. Recent cases include representing several complainants in big data investigations relating to Google Search, Android, Amazon and YouTube at European and national levels, private enforcement of competition law claims to compulsory licenses as well as advising on regulatory reforms in the area of digital markets, postal services and the press.

Thomas also acts as a Mediator in commercial disputes relating to online intermediaries pursuant to the Platform-to-Business Regulation (P2B-Regulation) No 2019/1150.

In September 2020, Thomas released a new book, Google’s (Non-) Compliance with the EU Shopping Decision, which can be downloaded here for free.

Having studied in Berlin, Glasgow and Dundee, Thomas holds a Ph.D and an LL.M in competition law. He is a professor of business law and intellectual property law at the Wildau Technical University of Applied Sciences and a Visiting Professor for telecoms law at the University of Strathclyde, Glasgow. Thomas has published, inter alia, four books on the regulation of networks and platforms and regularly speaks on current topics of competition and intellectual property law.
