He has tried federal and state jury cases, argued federal appeals, and been lead counsel in U.S. and international arbitrations.

Both in court and in front of arbitration panels, Tim has led cases involving cross-border mergers, joint ventures, licensing agreements, takeover contests, and international trade disputes, arising out of London, Paris, Saudi Arabia, Eastern Europe, Latin America, Russia, and various parts of Asia.

Tim has been involved in Jones Day's international efforts since the 1980s when he worked on defense of the General Motors/Toyota joint venture and the Gillette-Wilkinson merger, prosecution of Texas Instruments' patent rights, and participated in Jones Day's efforts to develop its offices in London, Paris, and Germany.
