Yahoo is not in good shape. This is a well-known fact. The company is now becoming an object of ridicule as they have just filed a patent infringement lawsuit against Facebook.

Yahoo claims Facebook is infringing on as many as 10 patents owned by them.

This comes just as Facebook has filed for a mega IPO worth around USD 100 billion. Facebook spoke about the lawsuit: “We’re disappointed that Yahoo, a longtime business partner of Facebook and a company that has substantially benefited from its association with Facebook, has decided to resort to litigation.”

Yahoo on their part said: “Unfortunately, the matter with Facebook remains unresolved and we are compelled to seek redress in federal court.”

Patent lawsuits are becoming very common in the web and mobile space. It is pretty clear that you cannot really launch any new web or mobile project without infringing on someone’s copyright in the US market.
