IBM vs. Asus 遭ITC駁回

IBM於2007年底時向ITC提出對Asus的專利侵權訴訟，系爭專利有：US5,008,829、US5,249,741及US5,371,852等三個專利，包括風扇、電源供應、與網路等個人電腦的相關技術。
IBM除指控Asus專利侵害外，亦提出禁止Asus產品進口並在美國銷售的要求。經過調查，在2009.3.ITC的行政法庭裁決Asus並未侵害IBM專利，但IBM仍然提出上訴。
ITC 2009.7.13.在官網正式駁回上訴，表示Asus確定並未侵權，該會也不會重審本案。

Title:Personal computer power supply
Filing Date:1990.6.14.
Issue Date:1991.4.16.
Abstract:
This invention relates to personal computers, and more particularly to personal computer power supplies for supplying electrical power to electrically operated components which manipulate or store digital data. The power supply has a controllable component for responding to the presence and absence of a low voltage direct current electrical signal by enabling and disabling the supply of electrical power to the data processing and storage components, and a signal generator circuit operatively connected with the controllable component and with an alternating current electrical main supply for controllably deriving from the main supply a low voltage direct current signal for delivery to the controllable component, whereby a user of the microcomputer may control energization of the electrically powered data processing and storage components by controlling the application of the low voltage direct current signal from the signal generator circuit to the controllable component.

Title:Method and apparatus for making a cluster of computers appear as a single host on a network
Filing Date:1992.10.14.
Issue Date:1994.12.6.
Abstract:
The present invention provides a method and apparatus for enabling a cluster of computers to appear as a single computer to host computers outside the cluster. A host computer communicates only with a gateway to access destination nodes and processes within the cluster. The gateway has at least one message switch which processes incoming and outgoing port type messages crossing the cluster boundary. This processing comprises examining certain information on the message headers and then changing some of this header information either to route an incoming message to the proper computer node, port and process or to make an outgoing message appear as if originated at the gateway node. The message switch uses a table to match incoming messages to a particular routing function which can be run to perform the changes necessary to correctly route different kinds of messages.
