Eric Goldman takes an in-depth look at the newly-filed American Airlines v. Google sponsored listings suit. From the professor’s post:
This complaint pleads the usual claims for this type of action, including direct, contributory and vicarious trademark infringement…; a false advertising claim that the “sponsored link” language communicates a false impression of actual sponsorship; dilution; various “soft” state claims (unfair competition; misappropriation and others); and tortious interference with contract because Google allegedly knew that American’s distributors weren’t supposed to buy American’s trademarks as keywords.
