Thomas S.Y. Lee Partner

Thomas is an amalgamation of unlikely backgrounds and disciplines. A former professional photographer turned lawyer, he is a tireless visualizer who does his best work when complex concepts require visuals that leave a lasting impression.

Much of his work has been in the area of intellectual property, where he serves a number of major corporations in their technology, consumer electronics, and life sciences industries. Most notably, Thomas was the lead consultant on several high-profile smartphone matters for a major U.S. consumer electronics company, one of which led to a jury verdict of $1.05 billion. When queried after the trial, jurors commented that the visual presentation was a particular point of persuasion in their deliberations and eventual verdict in favor of Thomas’ client.

Thomas was the lead consultant to Edwards Lifesciences in their jury trial against Medtronic, which resulted in a global settlement of more than $1 billion. He was also the lead consultant on the precedent-setting, multi-national Nortel trial that was held simultaneously in Toronto, Ontario, and Wilmington, Delaware.  More recently Thomas was the lead consultant for Harvard University against SFFA in an effort to protect affirmative action.

Throughout his career, Thomas has traveled all around North America to work on high-profile trials and arbitrations.  He was also recently a guest lecturer at Harvard Law School.  However, his most significant work has been at Impact where he works tirelessly with his partners, Bill Weir and Jesse Stevenson, to build one of the top trial consulting firms comprised of the strongest, most experienced talents in the industry.

In his free time, Thomas enjoys traveling, playing golf and spending time at local NYC playgrounds with his son, Lucas, and wife, Michelle.
