Brian’s practice is dedicated to obtaining robust patent protection for his clients’ innovation and developing strategies to minimize their patent infringement risk.

Brian has significant experience counseling clients with respect to a wide range of intellectual property issues, including patentability, clearance, and invalidity of utility and design patents. He regularly represents clients in the mining and heavy manufacturing industries, and he has significant experience in technologies including underground and surface mining machines, mechanical and hydraulic industrial equipment, power tools, manufacturing processes, control systems, and lighting fixtures and components.
