Stephan Kessler

Professional activity
Shortly after completing his master’s degree in biochemistry, Stephan Kessler discovered his interest in intellectual property law, whereupon he successfully completed his postgraduate studies in intellectual property at ETH Zurich. Following a short internship, he took up his first position as a “patent liaison” in an internationally active medical technology company. In order to obtain the necessary practice for admission as a European Patent Attorney, he joined a law firm in Eastern Switzerland as a patent engineer, where he was able to gain experience in patent law in a variety of technical fields. Since 2009 he has been bringing this experience to Keller & Partner Patentanwälte AG.
