Moore’s path to the courtroom began at the Massachusetts Institute of Technology, where he spent four years analyzing celestial sources. A pivotal decision in his final year led him to Harvard Law School, graduating in 1976. He spent the next three decades at Ropes & Gray LLP, where he became a partner in 1985 and emerged as an early authority on computer law. During the 1980s, he navigated the nascent landscape of software copyright, famously contributing to the passage of the Semiconductor Chip Protection Act.

In 2011, Moore established his own firm, K Square Law, to focus on corporate and intellectual property matters. His influence extends beyond private practice, notably through his long-term counsel for the Whitehead Institute for Biomedical Research and his work on a Massachusetts gubernatorial commission that modernized computer crime legislation. Throughout his career, he has remained deeply involved in academia, serving on the MIT Corporation and teaching at the University of New Hampshire School of Law. As the first chairman of the American Bar Association’s Committee on Technology and Intellectual Property, Moore remains a central figure in the evolution of cyber law.
