The key point of Eastern Pennsylvania's ruling on J.G Wentworth SSC Ltd v. Settlement Funding LLC case, is that the use of keyword-triggered ads and keyword metatags can be a case of duping if the resulting ads/search results don't display the plaintiff's trademarks. However, the court wisely differentiated between the use of logos and keywords for indicative purposes.
This ruling has eventually brought an end to consumer's confusion on Keyword Ads and Metatag.Hence, the keywords in the Google AdWords, Yahoo! SM account or keyword meta tags at the top of HTML pages are not an infringement attack.
Traffic.com gives a fine example to make it more clear: "If you owned clickstream data, as all of the major website properties (Google, Microsoft, Yahoo) do, you'd already have a very good idea of which consumers had, in the past, visited (say) the BMW site, or searched for "BMW". If you knew this, you could show them your ads at a later time in their surfing travels. Is that legal? As long as the privacy policies are disclosed, it sure is. It's called "targeting." What if you don't own that clickstream data? Shouldn't you be allowed to benefit from the same phenomenon, by participating in a system that works similarly?"
