Or a cynic might suggest that just by patenting every possible way of presenting search results they can prevent a competitor from getting ahead ;)

Slightly OT but the whole patent system needs looking at: Apple, Google, Samsung etc...they are all stifling technological advancement to protect their own interests. You can't blame 'em - anyone would do the same in their positions...it's the system that needs the overhaul.
