Facebook is turning the tables on Yahoo.
It is suing Yahoo, claiming patent infringement on 10 different patents.
This is in response to Yahoo’s lawsuit against Facebook, which says Facebook is infringing on a dozen patents. Facebook wants to have the lawsuit dropped, and it’s firing back to with patents it developed on its own, as well as purchased from outside companies.
In the suit, Facebook says all of Yahoo’s major properties are infringing on Facebook patents. Specifically, it says Flickr is infringing on Yahoo patents, as well as Yahoo’s optimization engine for its pages.
We have the suit below, and the patent infringement claims start on page 12.
