So they patented automated warrenty registration as well by this
I'm not too sure how to take this, in many ways if I buy something then I will register it for warranty. I'd have no problem with this, indeed from an insurance point of view this only helps, though in that respect i'm sure it will eventual get abbused by spoofed automatic generators perhaps down the line.
The aspect that I have a somewhat acute concern for is that some company will have sat on the internet a attached database that has a list of the goodies in my house. This is not something you generaly advertise since the advent of netcurtains, non-translucent bricks and curtians. The prospect that down to some bug that from a developer account you can goto google maps and pull up a satalite view, then goto streetview mode, thru the door and see a layout of your house with appliances included. Unlikely, though not impossible. That said alot of people don't think twice about posting a picture of every room of there house on facebook and the like's.
I'm not too sure how this will play out with amazon and ebay, especialy since alot of home kit can and does run through a setup that will automaticly register your product already. So in many respects it's a bit too open IMHO to actualy be something that is patentable, but we are talking USA patents right, not EU patent rights? I'm of the opinion there different and as such, with USA patent law, somebody in EU could do a patent and if somebody in the USA see's that patent they can submit it in the USA and if there first to submit they win. But it's not that silly, is it?
