Yahoo filed suit against the social network.
Company claims that the network violated some of their patents.
Facebook said it will “vigorously defend” the lawsuit related to the possible infringement of patents that Yahoo went against the social network. The information was placed by the company in an update of the documents submitted to U.S. authorities so that Facebook can make its debut on the stock exchange ( see documents here ).
The social network had registered 56 patents and 503 applications until December 31, the company said in a document registered with the Securities and Exchange Commission, regulator of the capital market in the country. With the purchase of IBM’s patents, the number should grow.
On 1 February, Facebook introduced their documents to regulatory agencies to make an initial public offering (the so-called IPO) expects to raise $ 5 billion . The premiere social network in the New York Stock Exchange is scheduled for May, with the symbol FB. The expectation is that the market is the largest IPO for an Internet company, surpassing the nearly $ 2 billion of Google, made ??in August 2004.
