Since 1939, the Mechanical Practice Group at Andrus has successfully protected the inventive creativity of our clients. The Group began by servicing greater Milwaukee's strong base of small, skilled craft shops and large manufacturing companies. As these companies came to dominate their industries, they consistently relied upon Andrus to protect their technological advances in heavy machinery, tools, engines, metal products, and medical devices. Over the years, the Mechanical Practice Group has expanded its practice and now also represents both public and private researchers and developers of complex mechanical and electro-mechanical technologies in various industries throughout the world.
