Yahoo Adds Two Patents To Facebook Suit

The latest volley in the unpopular patent-infringement lawsuit Yahoo filed against Facebook last month was fired by Yahoo, which claimed in a court filing today that it is not infringing on any of Facebook’s patents, along with adding two more of its own patents to the list of those allegedly being violated by the social network.

Facebook filed a counterclaim earlier this month, not only denying that it had infringed on the 10 patents originally included in Yahoo’s suit, but citing 10 patents of its own that it claimed were violated by Yahoo.

The two patents Yahoo added into the mix today were:

  • U.S. Patent No. 7,933,903, which covers a system and method to determine the validity of and interaction on a network.
  • U.S. Patent No. 7,698,315, which covers a system and method allowing advertisers to manage search listings in a pay-for-placement search system using grouping.

Yahoo also accused Facebook of breaking an agreement that the two companies would notify each other of possible patent infringements before going to the courts.

Yahoo issued the following statement about its court filing today:

Today’s filing underscores the breadth of Facebook’s violation of Yahoo’s intellectual property. As we have stated previously, Yahoo’s technologies are the foundation of our business that engages more than 700 million monthly unique visitors and represent the spirit of innovation upon which Yahoo is built. We intend to vigorously protect these technologies for our customers and shareholders.

OK, Facebook: It’s your turn.
