IBM is upset with ASUS, enough to announce just how upset they are. Claiming that ASUSTeK has committed patent violations, IBM has filed a complaint against them with the ITC. IBM's assertion is that three patents have been violated, including one for power supplies, another for controlling the speed of a fan and a third for “making a cluster of computers appear as a single host on a network”.
They claim that many ASUS products use IBM technology, from notebooks to servers to OEM components. You can read about the complaint at IBM's site
. The ITC has no comment about the situation, but IBM claims they have tried to work with ASUSTeK to no avail. There isn't any mention of a monetary compensation, so it may be that IBM is trying to get the ITC to bar imports from ASUSTeK.
