China’s largest telecommunications equipment maker, Huawei, has won a court order to block Motorola Solutions (Motorola, MOT.NYSE) from disclosing confidential information about Huawei’s technology to Nokia Siemens Networks (NSN), Bloomberg reported. The decision is expected to further delay NSN’s US$1.2 billion acquisition of Motorola’s wireless networks business. A Chicago court issued a temporary restraining order against disclosures by Motorola, and ordered the company to notify the court within 24 hours of any decision by China’s antitrust authorities to approve the pending acquisition. Shenzhen-based Huawei sued Motorola and Nokia Siemens on Monday, claiming that the transaction would "result in the massive disclosure of Huawei’s confidential information" to its rival, Nokia Siemens. Since 2000, Motorola has sold Huawei’s wireless-network products under the Motorola brand.
