(Telecompaper) Google and Samsung have joined Chinese mobile phone makers in expressing concern to Chinese authorities that Microsof's bid to take over Nokia's phone business may result in higher patent licensing fees, two government officials familiar with the matter told Bloomberg. Google and Samsung asked China's Ministry of Commerce to make sure that the acquisition doesn't result in higher fees on wireless technology patents that will remain with Nokia, the two officials said. They're also concerned Microsoft will gain more power over the smartphone market and may abuse its patents. Chinese vendors including Huawei and ZTE also asked China's regulators to set conditions on the deal, according to the officials. The takeover has been awaiting Chinese regulatory approval before it can be completed. China's Ministry of Commerce is conducting an anti-monopoly review and is likely to approve the deal, the officials said. The question is whether the ministry will demand the companies guarantee that the agreement doesn't result in higher patent fees.
