Dr. Christian Krauns holds a doctorate in physics. He has been admitted as a German Patent Attorney since 2005 and as a European Patent Attorney since 2007. Dr. Krauns is familiar with the Japanese language, as well as with Japanese patent law due to having lived and worked in Japan.

Legal Practice

Dr. Krauns has been active in intellectual property law since 2001, initially at a large German law firm specializing in Japanese clients, and since 2010 as a Patent Attorney at Wallinger Ricker Schlotter Tostmann.

Dr. Krauns' expertise in intellectual property law focuses on drafting, prosecuting and maintaining patents, trademarks, utility models, and designs in national proceedings (German Patent and Trademark Office) and in European proceedings (European Patent Office, Office for Harmonization in the Internal Market) as well as in international proceedings (World Intellectual Property Organization).

In addition, Dr. Krauns has extensive experience in proceedings before the Japanese Patent Office and in proceedings relating to Japan and Korea in general.

Technical Background

Dr. Krauns studied physics at the University of Göttingen, Germany and at the International Superconductivity Technology Center (ISTEC) in Tokyo. There, he initially specialized in metallurgy and materials science.

From 1992 to 1995, Dr. Krauns was an ISTEC fellow at the Superconductivity Research Laboratory in Tokyo, followed by a position as a research associate at the Institute of Metal Physics in Göttingen.

From 1998 to 1999, Dr. Krauns worked as a postdoctoral fellow at the Sophia Antipolis Technology Center at the Institut Non-Linéaire de Nice, followed by a fellowship at the Superconductivity Research Laboratory in Tokyo. In these research and development facilities, Dr. Krauns gained extensive experience in the fields of metal physics, metallurgy, materials science, solid state physics, semiconductor physics, catalytic processes, crystal growth processes, and thin film processes.
