Noted for its ‘extensive know-how’ and ’high flexibility’, Baker McKenzie Switzerland AG covers the full spectrum of competition mandates, such as immunity applications, merger control filings, and distribution systems. The team is able to capitalise on its global office network that spans London, Washington DC, and other locations to strengthen its capacity to advise. The practice is jointly led by Roger Thomi, whose varied experience encompasses the structuring of horizontal cooperation agreements and setting up antitrust compliance programmes, and Boris Wenger, who actively handles a litany of cartel and dominance cases as well as merger control proceedings. Veteran practitioner Philippe Reich assists with all facets of antitrust compliance.
