A go-to for patent disputes in Switzerland, Meyerlustenberger Lachenal has “an extremely strong team which makes valuable contributions to technical analyses and takes a creative approach to litigation strategy. They do a fantastic job in the pharmaceutical industry, especially for innovator companies, as they understand the local regulatory environment and its interface with the law exceptionally well”. Testament to this is its recent representation of Gilead in a widely publicised, multi-jurisdictional dispute against Mepha concerning Gilead’s SPC. Here, the innovative and compelling arguments presented by Simon Holzer and Michael Ritscher resulted in the successful defence and enforcement of the SPC, making Switzerland the only country in which this has been achieved. “One of the country’s finest”, Holzer is a first choice for life sciences cases: “He is client driven, committed and thoughtful, gets long-lasting and reliable results and is great to work with.” Consummate litigator Ritscher “knows everyone worth knowing on the local and European markets. He is accessible, easy to collaborate with and his guidance is always carefully considered”. The pair also link up with Kilian Schärli and Ulrike Ciesla to represent AstraZeneca across all of its Swiss patent matters. “Young, dynamic and bright” lawyer Schärli is “one of the best team mates you could think of. He is a focused and clear-cut adviser who always keeps clients’ business goals in mind”. Patent attorney Ciesla brings extra strength and depth to the firm’s offering: “She rapidly gets an insight into each case she works on, researches comprehensively and provides thorough advice on the best route forward, along with its pros and cons. She gives businesses the confidence and motivation to succeed.” The firm also recently welcomed Christian Fischer to the fold. An authority in the telecommunications sector, he was previously head of patents at Swisscom: “He is great at pinpointing weaknesses and inaccuracies when analysing technical arguments, presents arguments in a way that is easy to follow and does not shy away from challenging opinions that are not backed by clear facts.”
