  • Unfair competition

    Unfair competition

    The global market is characterised by free trade. The rules of this international economic exchange are expressed in unfair competition law. Comparative or misleading advertising, product imitation, the headhunting of personnel or price dumping may result in unfair competition proceedings. This affects all sectors, from the automotive industry to financial services, from retailers to the internet trade, or from the pharmaceuticals industry to the increasingly deregulated energy supply market.
