Main Activities

Technical, inorganic, physical, synthetic and organometallic and organic chemistry, pharmaceutics and cosmetics, as well as petrochemistry, glass/glass ceramics technology, automotive parts, adhesives, chemistry of catalysts and catalysis and plastics industry.


Wilm-Christian Haase studied general chemistry at the University of Bonn, receiving his Diplom graduate degree in 1996 and his doctorate in organometallic chemistry and organic synthesis in 1999. He went on to specialize in bioorganic, analytical and combinatorial chemistry during his postdoc research in the field of solid-phase synthesis of oligosaccharides at the Massachusetts Institute of Technology, Cambridge, U.S.

Dr. Haase has been working in the field of industrial property rights since 2001. He became a German patent attorney in 2004 and, in the same year, a European patent attorney and a European trademark and design attorney. Dr. Haase joined our firm in 2006 and has been a partner since 2010.

One focus of Dr. Haase’s work is in successfully representing his clients out of court in adversarial proceedings and in adversarial proceedings such as patent oppositions, trademark oppositions and appeals before the German and European courts. Dr. Haase has gained hands-on experience from successful patent nullity proceedings at every level of court up to and including the Federal Patent Court and from various proceedings (infringement, vindicatory action due to unlawfully acquired patent rights) before the regional courts. He advises and represents both medium sized enterprises and corporations, domestic and foreign, on all matters of industrial property rights, including searching for prior art, and maintains a network of foreign communicating attorneys in order to successfully bring international patent applications to grant, while always allowing himself to be guided by the individual needs of the clientele he is advising.
