Intellectual Property

Our IP Team, which has grown steadily since the 1990s, comprises some of Switzerland’s leading intellectual property law lawyers, covering all aspects of patent, know-how, trademark, copyright, design and unfair competition law. This includes clarifying the noninfringement of third-party rights, management of worldwide IP portfolios, exploitation and enforcement of intellectual property rights and defense against infringement allegations, both out of court and before state courts and arbitratral tribunals. Our well experienced team has the specialised expertise and human resources to help our Swiss and foreign clients succeed. We typically work in an international context. We follow the important legal, economic and technical developments in Switzerland and worldwide and often help shape them. Innovative companies, whether small, medium-sized or large, usually either have us on their side or as an opponent.
