Heralding Innovation™

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. HLG is joined by Stephen Y. Chow, who has a master’s degree in physics and forty years of full-spectrum technology law practice counseling and litigating on behalf of technology enterprises from start-up to Fortune 50. His practice focuses on intellectual property litigation, including patents he prepared and prosecuted, but also covers entity formation, finance and governance and deploying enterprise assets in global competition.
