In this Aug. 25, 2011 file photo, an attorney holds an Apple iPad, left, and a Samsung Galaxy Tab 10.1 at the regional court in Duesseldorf, Germany. The two tech Titans will square off in federal court Monday, July 30, 2012, in a closely watched trial over control of the U.S. smart phone and computer tablet markets. Apple Inc. filed a lawsuit against Samsung Electronics Co. last year alleging the world's largest technology company's smartphones and computer tablets are illegal knockoffs of its popular iPhone and iPad products.
