Lenz & Staehelin’s Thierry Calame is a “real favourite among the international patent litigation community”. Commentators admire his “global outlook and measured and skilful approach to litigation”. His background – including a master’s degree in chemistry and law – also distinguishes him from the pack.

Homburger partner Werner Stieger spends the majority of his time working on life sciences patent litigation, representing major pharmaceutical names such as Novartis and Roche. Sources describe him as “quickminded, incisive, direct, solution-orientated and practical”. He combines his life sciences patent litigation practice with general patents, copyright and trademark work.

The “strong and enthusiastic” Andri Hess entered the Homburger partnership in 2009 and already commands a fine reputation for his “clear legal analysis and valuable experience in the pharmaceutical field”. Commentators appreciate the “hands-on, extremely clientfriendly approach” of Rentsch & Partners’ Christian Hilti. He joined the firm last year, having previously run his own IP boutique. Primarily known as a trademark lawyer, Troller Hitz Troller & Partners’ Patrick Troller is also strong in patents and has been involved in a number of high-profile pharmaceutical patent disputes. Interviewees state that he is “thorough and exacting in considering the various possibilities and permutations of a case”.
