Yahoo accuses Facebook of infringing two more patents

First Yahoo sued Facebook over 10 patents. Then Facebook countersued Yahoo with 10 more of its own patents. Now Yahoo has added two more patents to the onslaught, bringing the total to 22.

Yahoo today replied in court to Facebook's countersuit by asserting Menlo Park is infringing on two more of Sunnyvale's patents. This brings the total of disputed patents to 22: 10 Yahoo patents, 10 Facebook patents, and now two more Yahoo patents.

Here are the last duo:

U.S. Patent No. 7,933,903 — “System and method to determine the validity of and interaction on a network” – Filed on January 22, 2010, and granted on April 26, 2011.


A computer implemented system classifies a user interaction on a network. An interface collects a user interaction data relating to a user interaction on a network. The user interaction data comprises an aggregate measure data or a unique feature data. The processor, which is connected to the interface, processes the user interaction data to generate a value score for the user interaction and determines a classification of the user interaction based on the value score.

U.S. Patent No. 7,698,315 — “System and method allowing advertisers to manage search listings in a pay for placement search system using grouping” – Filed on May 8, 2006 and granted on April 13, 2010.


A system for advertisers to efficiently manage their search listings in placement database search system includes grouping means for managing multiple categories for the search listings and query means for searching search listings. The system further includes quick-fill means for modifying an attribute in a plurality of search listings by specifying the modification at a single location.

In today's filing (embedded above), Yahoo also denies it violates any of the patents Facebook cites in its countersuit. Furthermore, Yahoo argues Facebook is not acting in good faith because it is using fighting Yahoo with patents that are not its own. Facebook did indeed buy eight of the 10 patents it's asserting against Yahoo from other organizations.

"Today's filing underscores the breadth of Facebook's violation of Yahoo!'s intellectual property," a Yahoo spokesperson said in a statement. "As we have stated previously, Yahoo!'s technologies are the foundation of our business that engages over 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."

"We remain puzzled by Yahoo's erratic actions," a Facebook spokesperson said in a statement. "We disagree with these latest claims and we will continue to defend ourselves vigorously."

Earlier this week, Facebook announced it is purchasing 650 AOL patents from Microsoft. Yahoo said the purchase showed Facebook is weak. Today's move really shows Yahoo wants to fight till the end.
