Great article by Aaron over on SEOBook:
So, Google may shift the rankings of your site, in what appears to be a random manner, before Google settles on a target rank.
Let's say that you're building links to a site, and the site moves up in the rankings. You would assume that the link building has had a positive effect. Not so if the patent code is active, as your site may have already been flagged.
Google then toys with you for a while before sending your site plummeting to the target rank. This makes it harder to determine cause and effect.
Just because a patent exists doesn't mean Google is using it, of course. This may be just be another weapon in the war-of-FUD, but it sounds plausible and itís something to keep in mind, especially if you're seeing this type of movement.
