The Yahoo!-Facebook tussle has finally come a full circle. Few weeks back, Yahoo! sued Facebook for infringing 10 of its patents related to advertising, privacy control, and social networking. Now, Facebook has counterattacked the search engine company and filed a patent lawsuit.


Ted Ullyot, general counsel of Facebook, said, “From the outset, we said we would defend ourselves vigorously against Yahoo’s lawsuit, and today we filed our answer as well as counter-claims against Yahoo for infringing ten of Facebook’s patents.” He further added, “While we are asserting patent claims of our own, we do so in response to Yahoo’s short-sighted decision to attack one of its partners and prioritize litigation over innovation.”


In the fresh lawsuit filed by the social networking giant, it has claimed that Yahoo! has violated 10 of its patents that include several web technologies, such as online advertising, tagging, photo-sharing, link-sharing techniques, and more.


The wait is worth it to find out who will win the race.
