WWL says

Lukas Rengier is lauded extensively by peers as a "rising star and definitely a future partner". He has an "impressive track record in cartel damages claims".


Lukas advises on all matters of European and German competition law. He defends clients in cartel investigations and follow-on cartel damages actions, conducts merger control proceedings for M&A transactions and advises on abuse of dominance issues and on competition law compliance.

He is defending a truck manufacturer in numerous lawsuits related to the trucks case, the largest competition litigation case in Germany to date. Lukas is also defending consumer goods manufacturers in damages proceedings related to the drugstore articles (KWR), consumer goods (HEMA) and consumer detergents cases.

He assisted a German chemical manufacturer in its largest acquisition to date, with merger filings in 10 different jurisdictions.

His PhD thesis, “Too Big to Fail as a Matter of Competition Law”, received an award by the University of Bonn and Deutsche Telekom in 2014.
