The IP team of Meyerlustenberger Lachenal is an outstanding group of professionals in all areas of IP law. Michael Ritscher, who heads this team, has an extensive track record of patent, trademark and copyright enforcement for large and mid-sized corporations not only in Switzerland but also in many other jurisdictions, often as lead counsel. When it comes to arbitration, Michael Ritscher regularly acts as counsel and his experience as extra-official judge at the Zurich Court of Commerce also predestines him as arbitrator or chairman in complex arbitrations.

He has substantial experience in both advising and representing clients in complex national and international patent disputes extending across a wide range of technologies, including pharmaceuticals, agrochemicals and medical devices.

Simon Holzer is also very active in the field of geographical indications as it relates to IP issues and has provided extensive expert opinions on this subject in court proceedings and to the Swiss authorities.
