Just got this off from EFF after reading an email from one of my mailings:

The Utah legislature has quietly passed a dangerous law allowing trademark owners to prevent their marks from being used as keywords to generate comparative ads. If this law takes effect, a company like Chevrolet couldn't purchase "sponsored link" space on the Google results page when a user types "Toyota" as part of a search query--at least if the latter term is registered in Utah as an "electronic registration mark."
