According to the source, Chinese officials are taking a more prudent approach with the Nokia-Microsoft deal due to requests from local handset manufacturers, including Lenovo, ZTE and rising star Xiaomi. Apparently, domestic players are worried that Nokia may begin charging higher patent fees now that it no longer needs to protect its handset interests, as it has in the past. The quoted licensing fees until this point were generally about 2% of the end product's selling price. It's, therefore, not surprising to see Chinese manufacturers, who have been using price as a main competitive advantage, appear weary of a future raise in prices for tech they simply can't go without. At least not cheaply.
As you can guess, Nokia's patent portfolio is one of the biggest there is, and it includes some pretty underlying tech, that most now take for granted. Nokia is fixating on this very advantage, and is very likely contemplating turning licensing its patented tech into a cash-making machine. In a previous interview with Reuters, Nokia spokesperson Mark Durrant noted as much:
Nokia is expected to make upwards of a billion dollars in 2014 from licensing fees alone, a sum that would represent a solid increase on the $684 million that the company is expected to cash in for 2013.
