Founders of Skype File Copyright Suit Against Company

Niklas Zennstrom and Janus Friis, who became billionaires after selling Skype to eBay in 2005, filed a copyright lawsuit against Skype in the United States District Court of Northern California. The suit comes a little more than two weeks after eBay announced it would sell most of Skype for $1.9 billion to a consortium of investors led by the private equity firm Silver Lake Partners.
