Wolf, Greenfield & Sacks, P.C.

The firm

Wolf Greenfield was founded in 1927 by Ezekiel (Zeke) Wolf, who began his patent practice at 10 State Street in Boston with his wife, Ray, as his secretary. Zeke was one of the first patent lawyers with a technical background to practice in Boston. His clients included Andrew Alford, later inducted into the National Inventor’s Hall of Fame; Reginald Fessenden, first to transmit voice across the Atlantic and inventor on over 450 U.S. patents in sophisticated radio transmission and sonar; and Radio Shack, a client from its beginnings as a single store in downtown Boston.

In the 90 years since then, the firm has grown to become the largest Boston-based law firm focused solely on intellectual property (IP) law, with more than 120 legal professionals. In September 2016, we expanded to a second office, in New York City. Leading companies, innovative startups, major research universities, and Nobel Prize winners consistently turn to us to protect and enforce their intellectual property rights. We learn their businesses and apply our knowledge of their industries, competitors, and markets to create IP strategies that simultaneously enhance the value of their IP and achieve their business goals.
