Yahoo Inc sued Facebook Inc. (FB) over 10 patents that include methods and systems for advertising on the Web, information sharing and privacy. Yahoo is looking for ways to revive growth after losing ground to Facebook in the display advertising market and trailing Google Inc. (GOOG) in Web searches. Yahoo claims it invented many of the techniques that Facebook uses to run its eponymous, ubiquitous, cloud-computing social network.
In an e-mailed statement, Yahoo said it is confident it will prevail.
“Unfortunately, the matter with Facebook remains unresolved and we are compelled to seek redress in federal court,” the company said in a statement.
“For much of the technology upon which Facebook is based, Yahoo! got there first,” the company argued in its complaint. “Facebook’s entire social network model, which allows users to create profiles for and connect with, among other things, persons and businesses, is based on Yahoo!’s patented social networking technology,” Yahoo said.
Facebook spokesman Jonathan Thaw said “Once again, we learned of Yahoo’s decision simultaneously with the media,” Facebook said. The company said it would defend itself against what it called “these puzzling actions.”
“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,” he said.
