Equity Partner at COHAUSZ & FLORACK
Christoph Walke studied electrical engineering, specialising in communications technology, at RWTH Aachen University, graduating with distinction in 1999. He then joined the Institute for High-Frequency Technology at RWTH Aachen University, working on the subject of space, code and time division multiple access radio systems, and obtained his doctorate with distinction in 2002.
Dr Walke’s education in IP law started at COHAUSZ & FLORACK in 2002. After further training at the District Court of Dusseldorf, the German Patent and Trademark Office and the Federal Patent Court, he was accredited as a German and European patent attorney in 2006. Dr Walke joined COHAUSZ & FLORACK as a patent attorney in August 2006 and became a partner in 2009.
Dr Walke has particular expertise in attacking and defending patents in invalidity proceedings – primarily those concerning technically complex and standard-related patents, as well as in drafting and prosecuting patent applications. He has also extensive experience supporting companies in their expansion of existing business fields and the acquisition of new business units through freedom-to-operate searches and due diligence evaluations. However, his main focus now lies in patent litigation between multinational companies, including pre-litigation infringement and validity analysis of patents for case selection, and on standard essentiality opinions for patent pools.
Dr Walke’s technical areas of expertise include information and communications technology, audio and video processing, data processing and software, cryptography and medical technology.
