By Paul Carsten BEIJING (Reuters) – Motorola, the mobile handset maker bought by China's Lenovo Group Ltd from Google Inc for $2.9 billion, is optimistic about its prospects in the Chinese market, its president told Reuters. Lenovo's acquisition, completed three months ago, ended Google's move into the consumer mobile handset business. The deal has turned personal computer-maker Lenovo into a challenger in the higher-end smartphone market, competing with Samsung Electronics and Apple Inc. "The (Chinese) market itself is so big here and Motorola has no share today, so we believe that what we’re really going to succeed in doing is hopefully take some share from other people in the market," Rick Osterloh, President of Motorola Mobility told Reuters.
