Groupon Sues Ex-Sales Manager Now at Google

Groupon Inc. sued two former sales managers who it claims took confidential trade secrets with them when they quit the Internet coupon company to join a competing venture run by Google Inc. Michael Nolan, who worked for Groupon for two years, and Brian Hanna, who joined the Chicago-based company in January, each left last month to join Google Offers, according to a civil complaint filed today in an Illinois court.
