September 23, 2009 - Social networking giant Facebook has been sued in federal court in Delaware for infringement of a patent owned by software manufacturer WhoGlue. WhoGlue sells web-based relationship management software used by groups such as alumni organizations.
The two-year-old patent-in-suit covers an "information management system, method and computer program code and means for facilitating communications between user members of an online network." The infringement is thought to be related to the privacy controls Facebook has put in place over the last couple of years to allow users more control over who sees which posts.
