Although its not on mobile didn't Google's desktop search tools cover an awful lot of this? I certainly remember it returning, emails, documents and other textual data in the result. It also had plugin support.

It may not have existed on mobile but one could argue that much of it did already exist on the desktop, bringing similar functionality to a mobile is not especially innovative in my opinion, its a feature at best. Integrating things is not innovative either.

I would love to see the fireworks of Apple taking Google to court on search patent infringement.
