What is now the firm of Wood, Herron & Evans began the practice of patent law in 1868. Colonel Edmund Wood hung out his shingle in Cincinnati, an important center of industry and commerce in the surging economy of the post Civil War era.

Our archives reveal the remarkable industrial and commercial energy of the time in records of innovative patents for mechanized farming equipment, new modes of transportation and machine tool developments that would help set the stage for the mechanization and eventual automation of the nation's exploding productive capacity.

The firm was focused on intellectual property law during its formative years. It gained early experience in the young chemical, machine tool, graphics and electrical industries as they emerged. Growing with a booming industrial base, the firm was headed by our founder and his son, William Wood, through the turn of the century.

Edmund P. Wood, grandson and namesake of the founder, led the firm into the 1930s. Truman Herron and Edward Evans became partners and helped accelerate its growth during the years of the Great Depression and World War II and into the modern era.

Over those 130 years, Wood, Herron & Evans has continued to flourish as a partnership in an ever-changing intellectual property environment. While our founders patented horse-drawn farm implements for a largely agrarian economy, our diverse practice now focuses on a new generation of innovation in a variety of technologies and the dynamic world of commercial enterprise. The firm is committed to remaining a leader in the arena where science, industry, business and commerce combine with intellectual property law.
