Google Inc Executive Chairman Eric Schmidt expressed confidence on Monday that Lenovo Inc would gain approval from U.S. regulators to buy Googles Motorola smart-phone hardware business in what would be Chinas biggest technology acquisition to date. Schmidt said he saw a good chance of the deal passing muster with the Committee on Foreign Investment in the United States, or CFIUS, which monitors acquisitions by overseas corporations. Speaking at a dinner organized by the Cato Institute think tank, Schmidt said Lenovos experience buying IBMs ailing personal computer division in 2005 would stand it in good stead as it seeks the green light to acquire the Motorola business. Theres a good chance of it being OK, Schmidt said, adding, We would not have done the transaction if we thought it would be in trouble. Lenovo said last week it would acquire the Motorola handset business, along with some 2,000 patents, for $2.91 billion.
