The Hsuanyeh Law Group (“HLG”) was founded by inventor-entrepreneur Hsuanyeh Chang, with a doctorate in theoretical physics and extensive experience in patent preparation, prosecution and litigation at major international law and manufacturing firms. Other patent law professionals in the firm also have advanced-degree and industry expertise in a wide range of technologies including the electrical and mechanical arts and life sciences.
