"Patentanwälte Isenbruck Bösl Hörschler lands its first spot in the rankings this year as “a reliable group of professionals characterised by profound knowledge of patent issues and excellent strategic insight”. Its thriving EPO oppositions practice is in particularly hot demand among biotechnology and pharmaceutical multinationals. Many of these are catered to by the “outstanding” Fritz Lahrtz , who has been with the firm since its establishment in 2003; he is highlighted for his “tough but fair approach” and “remarkable technical expertise”. At his side are fellow pharmaceutical aces Stephanie Nottrott and Stefan Féaux de Lacroix . Nottrott’s post-doctoral achievements in the biochemical and molecular biology fields underpin the “deep scientific understanding” she displays in commercially crucial office actions. Founding partner Feaux de Lacroix holds a PhD in polymer chemistry; he not only acts in a broad range of EPO oppositions, but also provides valuable support in courtlitigation."
