I'm not making stuff up.
Your implication is that as Google can legally allow people to use whatever keywords they want then it should be legal for people to use them.
Not really. Unfortunately - and I don't know if you're trying to score points or whether you just don't understand online advertising - you're simplifying what I'm saying to the point of making it too general.
So let me say it yet again: if the courts have decided that it's legal for Google to sell advertising on results pages for trademark keywords (which they have), it must be legal for people to buy that advertising.
The courts have indicated that it is not Google's responsibility to monitor what keywords are used. This doesn't mean that people can use whatever they want, as the onus is now on advertisers to choose legal keywords.
The courts have indicated that it's not illegal for Google to sell this advertising space. The implication is that the act of buying (and using) that ad space therefore isn't automatically an illegal act.
Anything else would be a nonsense.
So that leaves us with questions of libel and "confusion".
Libel is easy enough to dismiss as the ads don't mention the trademark or the trademarked company. And confusion is hard to argue because people know who Interflora are and who M&S are and they know they're not the same.
The one last argument is the argument by Interflora's lawyers that:
According to the lawsuit, "when a user enters the search term INTERFLORA or similar into the Google search engine, it is the intention of that user to look for [Interflora or its associates]."

But that's easily beaten by the simple catch-22 argument that, if M&S are taking business away from Interflora by running these ads, then clearly the people clicking on those ads aren't only looking for Interflora and their associates.
If they're not taking business away, then why are Interflora seeking damages?
So that doesn't stand up, either.
Throw in the defence that Google should have the same rights as any other internet publisher and what's left of Interflora's case?
I'd suggest "nothing", which is why I expect Interflora to lose this.
But, who knows? Maybe the judge will be incapable of understanding the subject? Maybe the M&S lawyers will do a poor job. As I said, who knows?
