Since this is apparently patentable, I'm actually kind of happy that it's Google that got it.<p>1) They're not going to actually enforce it because that would damage their image significantly.<p>2) In the absolute best unicorns-and-rainbows case, I can even see Google using it to demonstrate how ludicrous the patent wars are getting these days. This even makes a little bit of sense, given that the first hundred hits (on bing!) for '"Google sues" patent' are for patent countersuits.
