According to Yahoo, Facebook is infringing on its patents. In April, Yahoo sent a letter to Facebook stating that it was in infringement of 16 of its patents and also saying that these patents may be relevant to the technology that Facebook is using in its data centers and servers. Facebook has disclosed this in a regulatory filing. The social networking giant has data centers in North Carolina and Oregon and has been known to be innovative when it comes to developing their own server designs to help operate these data centers.
Yahoo has not threatened a lawsuit but it has left this possibility open for the future. In the past however, Yahoo sued Facebook in March stating that the latter was in violation of 10 of its patents and Facebook countersued stating the same. Yahoo’s return salvo was to allege that Facebook was stomping all over 2 additional patents.
Facebook is defending itself against the current lawsuits and the possibilities of new actions too.
