BiographyDr. Wang’s practice includes patent prosecution in chemical and mechanical arts with afocus on material science, polymers, catalysts, polyelectrolytes, pharmaceuticals,batteries, optics, display panel, virtual reality technology, circuits, and semiconductors.Additionally, Dr. Wang provides legal opinions and counseling on patentability, patentvalidity, and freedom to operate. Before joining WHDA, Dr. Wang is an experiencedresearch scientist who began as a lecturer at the university level in the Department ofChemical Engineering. Then came his postdoctoral work at MIT, followed by industryexperience in a corporate emerging science and technology group, and then in a jointcorporate/academic research Center at MIT.
