A new law firm has emerged following the dissolution of patent attorney firm Isenbruck Bösl Hörschler's Munich office. Patent attorney Sandra Zinner, who is formerly of Isenbruck, has founded her own firm specialising in life science and chemical IP.

Sandra Zinner (40) completed her application period at patent attorney firm Ruff Wilhelm Dauster in Stuttgart, moving to Isenbruck’s Munich office after her successful examination in 2013.
Here, she gained experience in patent prosecution in life sciences and chemistry. For example, in the patent dispute between Merck and Shionogi over compulsory licences for the HIV drug Isentress, she was part of the team led by Isenbruck partner Fritz Lahrtz and Taylor Wessing advising the Japanese patent holder.
In her new firm, which is called ZINNER, Sandra Zinner will also work for international companies. She has strong contacts to some US clients after a stint abroad. She will also work for some German medium-sized companies, especially from Bavaria.
Following the dissolution of Isenbruck Bösl Hörschler’s Munich office, other patent attorneys are also going in new directions. Some, such as Ulrike Herr, are moving to well-known German patent attorney firms.
The office’s two equity partners, Fritz Lahrtz and Stephanie Nottrott, moved to Simmons & Simmons in February with four other patent attorneys. Isenbruck then closed its Munich office completely.
Despite this, Isenbruck retains offices in Mannheim and Düsseldorf, with 15 patent attorneys and two of counsel. The firm’s technical focus on chemical and pharmaceutical patents remains.
However, it now has less expertise in biotech, with just two patent attorneys.
