In some fields of electrical engineering we have worked as engineers ourselves. As patent attorneys we cover almost the entire spectrum of this technical field. We have special experience in the following areas: Power electronics (circuit topologies and control techniques), control systems, semiconductor technology (manufacturing processes, structures and materials), integrated circuits, high frequency technology, communications engineering, electrical drives and machines (e.g. wind power technology), photovoltaics, sensor technology and measurement technology. For many years we have been continuously involved in obtaining and especially enforcing patents with these technical backgrounds.
