Pat(R)en(D)ting - To be read as tRenD in Patenting
Google's patent on location based advertising is yet another jewel added to their crown. This is definitely a patent that others in to online advertising would crave for.
I see a trend in patenting.... when an era (like touch phone, location based ad)is shaping up; more and more start ups are formed while the big companies do their part in R&D and later in to acquisition based on the investment they are going to be making in the future. Once the new era is sure to achieve greater heights, companies rush to get their work patented so as to secure a strong hold for themselves in the era and wish to be acclaimed as the champions of the era.
Although Facebook and Google may be happier with their news feed and location based ads patent recently, Apple must be thrilled with their numerous patents it has won over the multi touch interface.
