THE SOCIAL NETWORK Facebook has volleyed back a patents countersuit at Yahoo.
Yahoo sued Facebook in early March, saying that it infringes 10 of its patents that cover things like advertising, online privacy management and social networking. These topics are pretty key to Facebook's business, and the social networker said that it was "disappointed" to have been sued.
"We're disappointed that Yahoo, a long-time business partner of Facebook and a company that has substantially benefited from its association with Facebook, has decided to resort to litigation," it said.
Now it has turned around and fired a countersuit at Yahoo, saying that Yahoo infringes 10 of its patents that relate to web services and social networking.
"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," said a Facebook spokesperson.
"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."
Facebook said that Yahoo is using patents that cover things like posting headlines and news feeds. We have asked Yahoo to comment.
Late last month, after the firm had been approached by Yahoo's lawyers, Facebook confirmed that it had bought a chunk of IBM patents that could be handy here.
The firm would not go into details about what it got, but the suggestions were that they covered a wide range of web technologies. µ
