Orion Berg practices competition law and regulation, with a focus on electronic communications law, energy law, as well as sectors subject to EU regulatory law. He has extensive experience dealing with competition law disputes (abuse of dominance, cartels and private damages actions), as well as assisting companies in the context of multijurisdictional merger control filing (mergers, acquisitions and joint ventures). Orion also advises companies with their operations on regulated markets and dealings with public authorities in economic investigations (product safety and compliance, customs, consumer protection) including litigation before administrative courts. He represents foreign clients and their domestic affiliates in connection with the regulatory aspects of investing in France, to ensure that their business operations are fully compliant with all applicable regulations. He has also developed an expertise in state-aid advice.

In particular, Orion represents clients in national security reviews before the French Ministry of Economy with respect to commitment proceedings and prior clearance procedures under the regime of foreign investments control (FIC) which has been largely expanding since 2014.

A frequent speaker and writer, Orion teaches "Data regulation and electronic communications law" to students from Université Paris-Dauphine (Master 2 Droit et Régulation des marchés).

Prior to joining White & Case in 2008, Orion worked for several years in the competition and regulatory departments of two international law firms in Paris.
