Brad Stone talked to Professor Michael Klausner about the impact of the Skype lawsuit on the sale of the company:

The founders of Skype are escalating their legal battle with eBay.

Niklas Zennstrom and Janus Friis, who became billionaires after selling Skype to eBay in 2005, filed a copyright lawsuit on Wednesday against Skype in the United States District Court of Northern California.
