Nils Eichenauer

Dr. Nils Eichenauer was born in Düsseldorf in 1982, studied chemistry with a focus on organic chemistry at the University of Cologne and obtained the degree of Diplom-Chemiker in 2009 with his diploma thesis on “Orientierende Versuche zur Synthese mariner Oxylipine”. The research work for his diploma thesis under Prof. Dr. Schmalz in the field of synthesis of marine natural products at the Institute of Organic Chemistry of the University of Cologne was conducted by him at the Institute of Bioorganic Chemistry (IBOC) of the University of Düsseldorf at the Research Center Jülich.

In 2009, he started working as a research associate and doctorate student at the Institute of Bioorganic Chemistry of the HHU Düsseldorf at the Research Center Jülich.

During his research work in the field of natural product synthesis for his doctorate on the topic of “Development of new allyl boronic acid esters and their application in natural product synthesis” under Prof. Dr. Pietruszka, he dealt not only with methods of synthetic and preparative chemistry but also with the use of biotechnological processes for the production of chemical products, in particular with the use of enzymes in chemical synthesis.

In the course of a fellowship from the Japanese Society for the Promotion of Sciences (JSPS), Nils spent four months as a visiting scientist in Japan at Kyoto University with Prof. Michinori Suginome during his doctorate research on the synthesis of boronic acid derivatives by C-H activation using transition metals.

After completing his doctorate in 2014, he worked for a contract research organization, where his activities included implementing projects in organic and organometallic synthesis, polymer chemistry, and process development for various companies in the chemical and pharmaceutical industries.

In 2015, Nils started working in the field of intellectual property and successfully completed his education as a patent attorney with stations at the Düsseldorf Higher Regional Court, the German Patent and Trademark Office and the Federal Patent Court in 2018. Since 2019, he has been a sworn patent attorney and a professional representative before the European Union Intellectual Property Office (EUIPO).

He advises and represents national and international companies primarily in patent matters. Together with our clients, Nils develops and optimizes national and international intellectual property strategies and portfolios.

Nils joined GILLE HRABAL in 2015. In the year 2023 he was admitted as professional representative before the European Patent Office (European Patent Attorney).

He is married and has two children.
