Facebook Responds to Yahoo Patent Lawsuit With Counterclaims
This article is for subscribers only.
Facebook Inc., operator of the world’s biggest social-networking site, accused Yahoo! Inc. of infringing 10 patents through its home page and Flickr photo-sharing service and in ads displayed throughout its site.
Facebook, which was sued by Yahoo for patent infringement last month, made the counterclaims yesterday in a federal court filing in San Francisco. Facebook denied stealing Yahoo’s technology, saying its rival’s patents are either invalid or its claims legally barred and the lawsuit should be dismissed.
