Yahoo! filed a lawsuit against Facebook, accusing it of infringing 10 patents tied to an array of web technologies. According to the lawsuit, filed in Federal District Court in San Jose, California, Yahoo contended that Facebook had knowingly and improperly violated some of the company's core intellectual properties, the New York Times reports. The patents, which were issued from 1999 to 2010, cover advertising, privacy, customization, social networking and messaging. Last month, Yahoo warned Facebook that it may file suit over the patents. In its complaint, Yahoo seeks to use the words of Facebook cofounder Mark Zuckerberg against his company. It argues that Zuckerberg has conceded that Facebook isn't novel, but rather built on predecessors' innovationsYahoo. Yahoo! is seeking an unspecified amount of damages, and further requests that any such amount be tripled "in view of the willful and deliberate nature of the infringement."
