Microsoft asks Beijing to stop piracy at state-owned firms
Petroleum giant among state-owned companies accused of using illegal software, sources say

Software giant Microsoft Corp has asked China to stop the alleged use of pirated versions of its Office software by China National Petroleum Corp and three other state-owned companies, three people familiar with the situation said.

Microsoft alleged that more than 40 per cent of Office and Windows server client software used by CNPC, the parent firm of China's largest company by value, was unlicensed, the people said.
A Microsoft spokesman said he did not have any information on the filing.
A Beijing-based spokesman at CNPC said the company had not heard about Microsoft's complaints. He declined to comment on whether CNPC used pirated versions of the Office software.
Xu Zhaohui, who is in charge of hardware and software at China Post, said Microsoft's allegations were "inaccurate".
