A preliminary injunction has been issued Tuesday against Microsoft in connection with a patent infringement case, preventing the software maker from using a networking feature in Longhorn, its upcoming operating system release.
Last August, Microsoft Corp. was sued by San Jose, Calif.-based Alacritech Inc., a data networking firm that claims Microsoft infringed on its patents in developing its TCP-offload technology, code-named Chimney. The technology was slated for inclusion in the Scalable Networking Pack for Windows Server 2003, originally set for release in 2004. Alacritech had requested an injunction that would have covered Longhorn itself, effectively stopping the OS in its tracks.
