Two tech titans are squaring off in federal court Monday in a closely watched trial over control of the worldwide 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 smart phones and computer tablets are illegal knockoffs. Samsung countered that it's Apple that is doing the stealing and, besides, some of the technology at issue such as the rounded rectangular designs of smart phones have been industry standards for years.
