Fujitsu Computer Systems, Inc. / Corporation — Founded October 1, 2003, with headquarters at 1250 East Arques Avenue, Sunnyvale, California (N.D. Cal. venue). It was a wholly-owned subsidiary of Tokyo-based Fujitsu Limited, formed by merging Fujitsu PC Corp. and Fujitsu Technology Solutions Inc. It was consolidated with Fujitsu Consulting and Fujitsu Transaction Solutions into Fujitsu America, Inc. effective April 1, 2009; state filings show the entity later renamed Fujitsu America, Inc. and re-domiciled to Richardson, Texas. Standalone headcount/revenue for the subsidiary isn't publicly broken out; the parent reported roughly ¥3.9 trillion in annual revenue and ~140,000 employees globally in recent filings.
Products / operations. An operating company, not an NPE. Fujitsu Computer Systems sold and supported enterprise computing platforms in North America: Intel-based PRIMERGY servers, SPARC/Solaris-based PRIMEPOWER Unix servers, desktop and notebook PCs, tablet PCs, plus managed and professional services and break-fix support. It functioned as Fujitsu's North American enterprise hardware and services sales/support arm.
Patent-litigation posture. Sole tracked appearance is as a defendant (0 plaintiff, 1 defendant), consistent with an operating company targeted by an assertion entity rather than an active two-way litigant.
Notable case. Patriot Scientific Corp. v. Sony Electronics Inc. et al., N.D. Cal. (Oakland), Case No. C 03-5787 (filed December 2003). Patriot Scientific, a small San Diego IP-licensing company, sued Fujitsu and other Japanese PC makers (Sony, Matsushita, NEC, Toshiba) alleging infringement of U.S. Patent 5,809,336 ("High Performance Microprocessor Having Variable Speed System Clock"), seeking damages in the hundreds of millions. Patriot voluntarily dismissed the Oakland action on October 24, 2005, after assigning enforcement to The TPL Group/Alliacense for the Moore Microprocessor Patent (MMP) portfolio; TPL then re-filed in the Eastern District of Texas. Fujitsu purchased an MMP portfolio license and was dismissed from the Texas and California actions in 2006. Comments characterizing Patriot as a patent troll appear in contemporaneous press, but no merits findings against Fujitsu are reported.
