Dr. Christof Karl specializes in litigation and prosecution of patents, in particular in the technical fields of computer hardware, and software and telecommunications. He has ample experience in multi-jurisdictional cases in the field of telecommunications, including all aspects of patent-relevant anti-trust law. He also advises on issues of licensing, employee invention law, copyright law and Internet Law.

Mr. Karl represents clients in patent infringement proceedings before the German District Courts and the Courts of Appeal, and in patent invalidity proceedings before the European Patent Office, the German Patent and Trade Mark Office, the German Federal Patent Court, and the German Federal Court of Justice. In his patent prosecution practice, one of his focus areas is the patentability of software and other computer-implemented inventions. 

His clients include leading U.S. companies in the areas of computers, computer networks, telecommunications and financial services, a major Japanese computer game manufacturer, a world market leader for tobacco articles and e-cigarettes, as well as smaller and medium-sized German and international companies active in the fields of software, electronics, laboratory equipment, car supply, sports articles, hygiene articles, and food.

His unusual multiple qualifications as Attorney-at-Law admitted to practice in Germany and in New York, computer scientist, and German and European Patent Attorney enable him to handle both the legal and technical aspects of a case. His technical knowledge is particularly valuable in patent infringement proceedings, when the technical facts have to be precisely defined and communicated. In turn, his litigation experience and international focus allow him to draft patent claims which in the enforcement case prove to be powerful and valid, and to give strategic advice in building up cost-efficient worldwide patent portfolios, and monetizing them.
