Scott ThompsonPatent lawsuits are a thing nowadays, infesting the Internet at large and really putting a damper on the industry. The Apples and Samsungs of the world are the biggest names to throw around its muscle in court, but a breaking story suggests two new faces are getting in on the action.

According to All Things D, Yahoo is moving forward with a case against Facebook after sporadic talks apparently broke down. Yahoo is in the belief that Facebook has breached violations regarding “inventions in online advertising and social network without paying for the privilege.” Yahoo is asking for a percentage of Facebook’s revenue going forward.

Here’s is Yahoo’s full statement:

Yahoo! has invested substantial resources in research and development through the years, which has resulted in numerous patented inventions of technology that other companies have licensed. These 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. Unfortunately, the matter with Facebook remains unresolved and we are compelled to seek redress in federal court. We are confident that we will prevail.

Yahoo hasn’t been the most stable of companies as of late, with some big name departures and internal shakeups happening recently. The company must be pretty confident it has a substantial case if it’s decided to take on Facebook.

We’ll update once we know more.
