Over the past 35 years, Brian has served as lead trial counsel in jury trials and other litigation involving a wide range of patents, including pharmaceutical and biotechnology products, infant formulas, medical and orthopedic devices, nutritional compositions, advanced magnetic materials, plastic compositions, sailboards, fiber-optic connectors, and jet engine fuel controls.
