What implications does Yahoo's Patent Infringement lawsuit have for Facebook? Bill Slawski describes these, providing insight into what it all means. Some might think Yahoo's patent infringement suit against Facebook came out of left field Monday, but the situation was brewing for weeks prior to this. The patents point to Overture ad technology, as well as Yahoo's patents on social networking, advertising, customization, privacy and messaging, according to Slawski. The social networking patent was granted in June 2010 and filed in February 2005.
