"Operating on both sides of the contentious/non-contentious divide, Rentsch Partner is one of the best firms for patent work in Switzerland. The group aids clientele at every stage of the patent lifecycle, and its practitioners are proactive, committed to the client and at the top of their fields. The team handles applications smoothly, even if they fall under new categories.” On the contentious front are Christian Hilti and Demian Stauber. Alongside patent attorney Louis Lagler, they come highly recommended: “Stauber has been very supportive in the past in developing an IP strategy and has been part of the strategy workshops with our business units alongside Hilti and Lagler. With their help, we have been able to raise and develop our staff’s awareness of functioning IP strategy.” Lagler has broad knowledge in the field of IP and knows how to use it well. Creativity, reliable work, swift response times and a great grasp of technical details are just some of the characteristics of Lagler that patrons appreciate. They benefit from his commitment to their business needs and an interest in technical developments. Also holding down the fort on the non-contentious side are Dany Vogel, Andrea Carreira and Alfred Köpf. “Vogel has profound knowledge in new technologies. His expertise is of the greatest benefit to every client. He is committed to his clientele and offers goal-oriented discussions.” Combining almost three decades of experience and in-depth life sciences expertise, Carreira is an asset to those seeking litigation and arbitration support. “With a pragmatic approach and an open-minded attitude, Köpf is an expert on patent applications related to all kinds of technology."
