Softvault, a Washington based Intellectual Property company, has sued Microsoft and many other tech firms including Yahoo for alleged patent infringement. The main patent in question is "US patent 6,249,868". It covers security components for a computer which can enable or disable systems by use of a remote server. Softvault also claims that the companies it has targeted are infringing another one of its patents, US patent 6,594,765.
Another case against Yahoo, Napster, Creative Labs, Dell, Gateway, Iriver, Samsung, Toshiba, Digital Networks, Palm, Audiovox, Sandisk and Thomson relates to the same patents but is slightly different. Softvault alleges that Microsoft distributes the Windows Media DRM software, which breaches its patent, and the other tech firms use the same DRM so they also infringe the patents.
