Jason regularly represents manufacturers as both plaintiffs and defendants in patent, trade secret, and commercial litigation before district courts and at the International Trade Commission (ITC). Jason authors the quarterly “Patent Update” column in Chemical Engineering Progress, the flagship publication of the American Institute of Chemical Engineers.
