  • George L. Paul

    Greg Guillot is one of the most outstanding copyright lawyers in the United States, bar none. I worked closely with him on a case in the 8 figures. He is a meticulous scholar, a superb writer, and an excellent strategist. He is one of the most creative thinkers there is -- in a field that values creativity above all else.
