Sterne Kessler is an IP powerhouse known for its deep technical bench. The firm has more than 200 lawyers, patent agents, and technical specialists, many of whom hold advanced degrees in science and engineering disciplines, including over 60 Ph.D.s.

Many of the firm’s professionals have prior experience as in-house counsel, engineers, and inventors. In addition, the firm has former U.S. Patent and Trademark Office examiners and lead administrative patent judges from the Patent Trial and Appeal Board. This combination of experience provides clients with rare and valuable insight into how patent rights are examined, challenged, and enforced.
In the last five years, Sterne Kessler has served as litigation counsel in 200+ patent cases across nearly 30 federal district courts. The firm is one of the top five most active firms for patent cases at the U.S. Court of Appeals for the Federal Circuit, and among the top 10% of most active firms at the U.S. International Trade Commission.
