About Wolf, Greenfield & Sacks, P.C.

Founded in 1927, Boston’s Wolf, Greenfield & Sacks, P.C. has grown to be one of the preeminent intellectual property firms in the Northeast and has been a fundamental part of some of the most important IP decisions in history.

A History of IP Expertise

From its beginning, when patent attorney Ezekiel Wolf opened up shop in Prohibition-era Boston, Wolf Greenfield has attracted notable clients. In its first decades, clients included famed electrical engineer Andrew Alford and radio pioneer Reginald Fessenden. Now, Nobel Prize winners, Fortune 500 companies, high-tech startups, and major research universities rely on the firm to protect and enforce their IP rights.

Wolf Greenfield’s reputation in IP law carries historical weight. In 1961, the firm successfully argued Aro Manufacturing Co. v. Convertible Top, now known as the seminal Supreme Court case covering the doctrine of permissible repair. A few decades later, in the much different technological era of 1998, the firm’s lawyers crafted the winning argument in the landmark State Street case, which set the stage for software patents and the patentability of business methods. More recently, the firm won the second longest patent interference proceeding in USPTO history and the largest jury verdict in a trade secret case in Massachusetts history.

The firm represents clients large and small in patent litigation in district courts around the country and on appeal before the Federal Circuit. In addition, the firm’s lawyers are frequently called upon to represent technology companies in high-stakes patent litigation before the International Trade Commission, where Wolf Greenfield has an outstanding track record of success. The firm has achieved successes such as summary judgment of patent invalidity in the Eastern District of Texas (known as a difficult district in which to secure such summary judgments) and groundbreaking rulings on novel issues such as the proper claim construction for mouse nomenclature in patent claims covering transgenic mice. The firm also has a long and successful history in post-grant matters before the Patent Office and is regularly engaged by clients when the stakes are high.
