When the stakes are high or new law needs to be established, industry-leading clients turn to intellectual property litigator Adam Kessel. He has an exceptional record of success at trial and on appeal in federal courts across the nation, in cases before the U.S. International Trade Commission, and in post-grant proceedings before the Patent Trial and Appeal Board.

Adam focuses on IP litigation, particularly cases involving patent, copyright, trade secret, and state-law claims involving software, computer networks, electronics, and medical devices across all areas of IP. He also litigates in related areas such as the Digital Millennium Copyright Act and the Computer Fraud and Abuse Act. He has represented both plaintiffs and defendants, tried dozens of cases to a jury, and appeared in state and federal courts across the country.

He frequently represents clients in the U.S. District Court for the District of Massachusetts. He has argued and won motions and claim construction arguments before most of the judges on the bench and has tried cases to a jury before several judges in the district. Adam has handled cases in at least 11 other districts, including in IP hotspots such as Delaware, Texas, and California. He has argued numerous appeals before the First, Fourth, Eleventh, and Federal Circuit Courts of Appeal. Adam also handled nearly 200 criminal cases as a "lawyer on loan" to the Suffolk County District Attorney’s Office (2009-2010), several of which he took to trial as first chair.

Strategic and tactical, Adam thrives on a challenge. He has served as lead lawyer in precedent-setting cases, multidistrict litigation, and disputes involving novel issues of law. His carefully crafted persuasive, logical, and creative arguments have achieved wins at trial and on appeal for iconic brands that include Microsoft, Adobe, and Bose. Adam is equally skilled in resolving matters through negotiated settlements when avoiding protracted litigation makes the most sense for his clients.

Adam also advises on open-source software and patent and software licensing issues in a wide variety of contexts, including negotiated transactions, mergers and acquisitions, investment due diligence, internal best practices and policies, and litigation. As a former software developer, he brings exceptional insight into the technologies and their uses, which proves helpful in guiding his clients and structuring deals.

Adam is involved in several local legal- and IP-related organizations, including serving in the counselor role for the Judge Lourie Intellectual Property Inn of Court and as a chair of the case law committee for the Boston Patent Law Association. Adam maintains an active pro bono practice handling civil liberties cases.

Before joining Fish, Adam was a judicial intern for the Honorable Reginald Lindsay of the U.S. District Court for the District of Massachusetts (2003). He earned a degree in chemistry from Princeton University, developed software for several companies, and conducted research for an academic biochemistry lab involving protein structure and nuclear magnetic resonance spectroscopy.
