Clemens has conducted numerous patent infringement lawsuits before the German civil courts and has worked on parallel validity proceedings before the German Patent and Trademark Office, the German Federal Patent Court, the German Federal Supreme Court and the European Patent Office. He has a great deal of experience in coordinating multi-jurisdictional patent disputes (including arbitrations) in Europe. Clemens is also active in client counselling as regards licensing, transactional IP and the law of employees' inventions.
