In 2000, Howrey & Simon merged with Arnold, White & Durkee, an intellectual property specialty firm founded in 1956 in Houston, Texas with offices in six cities and 120 attorneys. This combination resulted in the new firm of Howrey, Simon, Arnold & White, with 350 lawyers, one of the largest antitrust and intellectual property practices in the world, and laid the groundwork for the firm’s expansion overseas. Between 2000 and 2008, the firm expanded to more than 700 attorneys and 17 offices in the United States, Europe and Asia.
