Andy Beal posted at his blog English Courts Rule Using Trademarks in Meta Tags Legal, which has a link to the ruling.
Last week I attended an interesting session at the SES conference named Leggo My Trademark: A Search Engine Legal Update, which discusses these issues. To sum up that session, "Trademark infringement is use of another's mark that is likely to cause consumer confusion, or to cause mistake, or to deceive as to source, affiliation, sponsorship, origin or approval."
I am happy to say that the session at SES was right on the mark with the ruling in the UK court. Not only was the reason behind the ruling right, the definition of trademark infringement remains the same in Europe as it does in the US. Check out the ruling here
