Craigslist Files Countersuit Against eBay

Craigslist filed a countersuit against eBay, alleging that the Internet auction company engaged in unfair competition, trademark infringement and a slew of other improper activities. The move comes less than a month after eBay sued Craigslist, claiming the privately held online classifieds company tried to dilute its ownership stake in Craigslist and removed its representative from the board of directors.
