Chipmaker Intel has filed a patent-infringement lawsuit against Via Technologies and will seek to have Via's new Pentium 4 chipsets pulled off the market. Santa Clara, Calif.-based Intel on Friday filed suit in U.S. District Court in Delaware. The lawsuit alleges that Via's P4X266 and P4M266 chipsets, which were released earlier this month, infringe on five Intel patents. S3 Graphics is also named as a defendant. S3 Graphics is a joint venture created by Via and Sonicblue--a graphics chipmaker turned consumer electronics company--to help develop chipsets. Via's two chipsets essentially allow computer makers to put DDR DRAM, a high-speed form of standard computer memory, inside computers with Pentium 4 chips. Currently, only Rambus memory can be used inside Pentium 4 computers, although chipsets that let PC makers use ordinary SDRAM will come out Monday. The complaint seeks damages, as well as a permanent injunction that would effectively prevent Via from selling the chipset.
