Recognised by Who’s Who Legal in 2018, 2019, 2020, 2021 and 2022 as a “future leader” in competition.
Clemens is committed to help businesses to quickly adapt to new requirements, to realise cost savings and other efficiencies. He provides business-oriented and pragmatic advice on minimising antitrust risk and on EU State aid law.
After over a decade in two major international law firms (Cleary Gottlieb and Hogan Lovells) in Brussels, with placements in Washington D.C. and Copenhagen, in 2019, Clemens started up his own boutique law firm in Brussels.
Advice in EU State aid law matters is a focus of Clemens’ practice. Further, not least due to his experience in competition compliance officer positions, Clemens also assists companies in managing antitrust risk, for instance by designing and implementing compliance programmes. He also advices on cooperation agreements and vertical agreements, including such with sustainability objectives. Clemens handles complex, multi-jurisdictional merger transactions and other types of regulatory filings. He also assists clients facing cartel investigations.
