Specialties & Experience of this Expert Witness

Additional Information

In addition to being a Professor, Bruce E. Kahn, Ph.D. is an expert witness, researcher, analyst, lecturer, author, and consultant. He has a diverse multidisciplinary background in many areas including functional printing (2D and 3D), additive manufacturing, advanced manufacturing, photography, imaging, inks, materials science, nanotechnology, and chemistry. He has been involved in functional printing and additive manufacturing since 2002, and nanotechnology since 1990. In addition to working with academic, commercial, legal and governmental organizations, he writes books, articles and reports, and conducts training sessions and workshops in the US, Europe, and Asia. In 2014, he received the Flexi award for technology leadership in education from the FlexTech Alliance. Dr. Kahn has served as an expert witness 5 times, including cases on environmental remediation (Superfund cleanup), patent infringement, trademark infringement, and patent invalidity. He has been deposed 4 times (so far), with one case just starting. He has assisted with due diligence and advised a number of companies. Dr. Kahn has directed research programs on RF energy harvesting using printed metamaterials, rapid automated metrology of printed features, and the influence of scale up and printing process parameters on printed devices using commercial scale flexographic and gravure printing. His research has produced a variety of materials, structures, and devices including printed ceramics for hydrogen generation, highly conductive and high current carrying metal traces, aligned metal nanowires, metal alloys, magnetic inks and materials, metal precursor inks, dental materials, RF energy harvesters, transparent conductive films, multilayer devices, chemical sensors, and antennas for Radio Frequency Identification (RFID) tags. He has used, taught, and written about a variety of printing processes including flexo, gravure, screen, thermal transfer, offset lithography, extrusion, ink jet, aerosol, 3D, and Metallojet. Dr. Kahn has a Ph.D. in Chemistry from the University of Nebraska, and a S. B. in Chemistry with a minor in Economics from the University of Chicago. He is the author of over 100 publications and presentations, including the books Developments in Printable Organic Transistors, (Intertech-Pira, 2005), Printed and Thin Film Photovoltaics and Batteries (IDTechEx, 2007-2012, 6 Editions), and Displays and Lighting: OLED, e-paper, electroluminescent and beyond (IDTechEx, 2008).
