Experience and passion
Even after more than 25 years in the profession, Joachim Renken is still passionate about his job - always eager to learn about new technologies and to accept new challenges.
Joachim’s practice extends to all areas of the life sciences, from gene editing to sub-diffraction fluorescence microscopy, from cell therapy to small molecules. His ample experience in both patent prosecution and litigation allows him to provide his clients with thorough strategic advice, be it in the context of creating strong patent portfolios or IP due diligence.
Joachim is particularly active in contentious proceedings - EPO oppositions and appeals, nullity proceedings before the German Federal Patent Court and the German Federal Court of Justice, and infringement proceedings before the (Higher) Regional Courts. He has been invited by the EPO to share his experience in oral proceedings by videoconference in several webinars and a podcast.
Joachim also devotes time to the development and management of the HOFFMANN EITLE offices in Madrid and Barcelona.
When not at work, you can often find him on the tennis court or in the mountains.
