Case Overview

Asustek Computer, Inc. filed patent infringement claims against International Business Machines Corporation (IBM) in the United States District Court for the Northern District of California. The lawsuit, docket number 3:08-cv-01168, centered on allegations that IBM infringed multiple patents held by Asustek related to computer hardware technologies.

Timeline and Case Development

• Filing Date: February 2008
• Initial Allegations: Asustek claimed IBM’s CPU and related computer hardware products infringed two patents: U.S. Patent No. 6,584,294 and U.S. Patent No. 7,198,170.
• Defendant Response: IBM filed motions to dismiss and submitted counters, disputing the validity of the patents and the alleged infringement.
• Settlement and Dismissal: The case did not proceed to trial. In December 2009, the parties settled, and the case was dismissed with prejudice.

Patent Details

Patent Number	Title	Filing Date	Issue Date	Key Claims	Technology Focus
