IN MEMORIAM

 

Thomas P. Sullivan

1962–2026

Tom Sullivan was a founding partner of L&A and served for many years on the firm’s Management Committee. Over more than two decades with the firm, he worked closely with some of L&A’s largest and longest-standing clients, helping them build, maintain, and enforce their patent portfolios. Before IP law, he was a Senior Electrical Design Engineer at Raytheon, contributing to communications and missile defense systems for the U.S. Department of Defense — work that shaped how he thought about IP strategy for the rest of his career.

Beyond his practice, Tom was a dedicated educator and mentor. He served on the Suffolk University Law School Dean’s Cabinet, taught in the Accounting and Business Law Department at the Sawyer Business School, and spent several years as Vice Chair of the City Year Legal Community Annual Breakfast. He helped shape not only the firm he co-founded, but the broader Boston legal community he was part of building.
