About Wolf, Greenfield & Sacks, P.C.

One of the most reputable firms in Boston, Wolf Greenfield has made a name for itself as an IP powerhouse. With just under 100 attorneys, Wolf Greenfield is known for its work in patent litigation on technology matters. The firm has kept to the East Coast with one office in Beantown and one in the Big Apple.

IP Roots

Wolf Greenfield was founded in 1927 by patent attorney Ezekiel Wolf in Boston. In its first decades, clients included famed electrical engineer Andrew Alford and radio pioneer Reginald Fessenden. The firm is no stranger to making history, and over the years has had its hand in some of the most important IP developments. 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.

Got Science?

Wolf Greenfield focuses on eight main practice areas: biotechnology, chemical and material technologies, electrical and computer technologies, litigation, mechanical technologies, pharmaceutical, post-grant, and trademark and copyright. The firm files thousands of patent and trademark applications each year. And its bench has deep experience—more than 90 percent of the firm’s professionals have backgrounds in engineering or science and more than 50 percent of attorneys previously worked as engineers or scientists.

The firm represents clients large and small clients in patent litigation in district courts around the country and on appeal before the Federal Circuit. Its 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. Wolf Greenfield 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.

Technology Specialists

Wolf Greenfield isn’t the only firm with technology specialists—but it was the first to do it in Boston. In 1988, the firm launched its technology specialist program, which continues at the firm today. The firm’s technology specialists assist in making the scientific data and work relating to patents understandable. Among their tasks include client interviews, research, drafting patent applications and communications to the USPTO, and reviewing patents. Specialists follow one of two tracks at the firm, either attending law school part time or developing a career as a patent agent.

September 2019

For the third year in a row, Patexia Inc.—an intellectual property community and information service—has named Wolf Greenfield among the top-performing and most active law firms for inter partes review (IPR). Wolf was ranked in the top 1 percent of all U.S. firms for success rate and was one of only two firms to be named in the Top 20 best performing firms for both petitioners and patent owners. Wolf was also ranked as one of the most experienced IPR practices in the country, in the top 5 percent of all firms based on the number of cases handled.

Rich Giunta, the chair of our Post-Grant Proceedings Group, was ranked in the top 1 percent of all U.S. attorneys for both overall success rate and number of cases handled. Shareholders Randy Pritzker, Mike Rader, and Ed Walsh were also recognized as top performers.

According to the firm, its Post-Grant Proceedings group continues to have an outstanding track record of success. The Legal 500 called it “one of the most successful PTAB practices in the US,” and Managing IP recognized the firm as “notable in the PTAB arena, with impressive expertise in post-grant proceedings and IPRs.” The IAM Patent 1000 recommended Rich Giunta nationally for post-grant proceedings.
