Microsoft Applies For Patent On Private Browsing
PhilDEE writes "Microsoft is in the process of applying for two patents for a private browsing mode in their next version of Internet Explorer — a feature already present in Safari, among other browsers."
This is just like their tabbed browsing patent.
M$ Business model: find an unpatented feature in an open source browser. Implement it in IE, then patent it. Sue the pants of the people who dared infringe on it.
