“After an eight-week trial, the jury had the clarity it needed to reach a defense verdict in less than a day of deliberations. From juror interviews, we learned that the jury had relied upon and understood our case because of the excellent graphics we used. IMS partnered with us not only in creating the trial graphics, but also helped us present a convincing, illustrative opening statement and closing argument. Because the jury was able to firmly grasp the technical details from the defense case, it was able to make the right call.”
