Story: Microsoft patents 'Page Up' and 'Page Down'

• 

must be careful now, I could be infringing a patent

Do you think they employ people to continually check if a patent exists for some of the most common items in use these days?

What possible motivation is there to go seeking patents like this other than being able to sue over patent infringement.

So I guess i'll need to hold my breathe for/on the day a headline reads:
Microsoft to patent "breathing in" and "breathing out"
