The Competition team of CMS Switzerland advises across the full range of Swiss and EU antitrust and competition matters. Based in Zurich and Geneva, the two main Swiss financial centres, we are part of the wider CMS Antitrust, Competition and Trade (ACT) group, one of the largest specialist competition and trade teams in the world. More than 225 CMS experts advise clients in more than 40 countries worldwide on all ACT matters.

We cover all key areas of Antitrust, Competition and Trade law – internationally and in Switzerland:

  • Competition and cartel investigations
  • Merger Control
  • Vertical agreements
  • Horizontal agreements
  • Abuse of dominance and economic dependence
  • Unfair competition
  • Compliance
  • Private enforcement
  • Trade law and sanctions
  • Foreign investment screening
  • Digital markets
  • Regulatory

We represent our clients in proceedings before competition authorities such as the Swiss Competition Commission and other regulatory authorities as well as courts. We have renowned sectoral experience, including in automotive, construction, consumer products/FMCG and retail, energy, life sciences, IT services, payments solutions, and telecommunications among other sectors.

Our clients range from large multinationals who frequently use our team as their ACT law firm of choice for the entire region, to governments and a high number of small and medium-sized companies.

Our size and very wide footprint enable us to handle all ACT matters irrespective of their geographic dimension. Where necessary we cooperate with long established contacts from our wider network of law firms across the world. 

We use the most up-to-date technical and AI tools to support our business in Switzerland and abroad.

We run frequent webinars and events on Swiss and EU competition developments and hold a renowned annual EU competition law conference, which has become a feature in the Brussels calendar.  We put out regular case law updates on competition and trade developments on our Law Now service.  Moreover, our international group is steered, not just by a management committee of partners but also by an active associates’ group that keeps us innovating to serve clients.
