And last, but never least, in our patent round up of the Big 3 (though it will likely be 2 now with Yahoo going the way of the Dodo) is of course; Google.

As we've seen with the others, there is a distinct increase in the geo-local areas. While patents tend to be older than a year (from time of filing) it is still interesting to see this. We all know, or should, that local is the in-thing over the last few years. Is it a coincidence that the patent filing mimic this? Probably not.

Also interesting and likely telling were the number of systemic related patents. Why telling? Because 2010 for Google was all about Caffeine and other infrastructure upgrades.
