Now Facebook is countersuing Yahoo, denying Yahoo’s allegations that Facebook infringed on the company’s patents — and claiming Yahoo is actually infringing on Facebook’s patents.
Facebook’s counter-claim, filed Tuesday, denies Yahoo’s statements that many of Facebook’s tools and features on the site stem from developments made by Yahoo. Facebook requests that any triable issues be taken to court.
The social network also says Yahoo is in violation of some of its patents, including patents the company holds for “generating a feed of stories personalized for members of a social network,” and “tagging digital media.”
Facebook says it plans to fight the original lawsuit.
