Yes, I'm sure Rich Recording is patented, but the general principle of all device manufacturers now having to work to produce audio capture electronics that do the same job has to be good for all of us in the long run.
For years, phone owners have shot bits of life, events, concerts, and so on, knowing that the audio from their clips will be unusable (and that the video wouldn't be very good either) - we now have a phone that can grab video and audio with near perfection. The Nokia 808 PureView absolutely sets the bar here for everyone else to follow, in my opinion.
From the video description:
Sample video taken with the Nokia 808 Pureview. This time no bright sunlight to make it easy for the camcorder. Instead, it is filmed in a dark area with colourfull spotlights and lots of fast movement.
Since there is very loud music playing, this is a good chance to hear what Rich Recording can do for the audio. I've edited in a short clip from the same event taken from the Galaxy Nexus for good measure. The difference is pretty straight forward.
