It appears that US courts are getting more and more savvy about Internet marketing (or US attorneys are getting more and more savvy about their “expert” witnesses in these cases!). Last week, the 11th circuit court ruled that meta keywords aren’t effective for SEO (so trademark infringement in them didn’t really matter anyway), and the US District Court in the middle district of Florida ruled that a trademark infringing AdWords advertiser would have to use negative keyword matches in future searches.
