Acer Inc (宏碁) chairman and CEO Jason Chen (陳俊聖) on Tuesday said that the PC maker's royalty payments to Microsoft Inc are governed by contracts with the US software giant and are not paid by partner original design manufacturers and electronics manufacturing services providers. Chen's comments came amid a patent dispute between Microsoft and Hon Hai Precision Industry Co (鴻海) that prompted personal rebukes by Hon Hai chairman Terry Gou (郭台銘) earlier that day. Acer pays Microsoft directly to fulfill the conditions of the licensing contracts, Chen said.
