It's just a patent. The bulk of the patents are never used.

The title says that Airbus invented a new type of plane, but that design was create by someone else I thought.

I don't understand. It's easy to add passengers to a tube-and-wings. Just stretch the tube. This would involve a whole new type. And there's a lot more wing-to-payload going on here.

Only if Airbus is doing a Double-Decker-NEO option.

How would something like this pass evac standards?
...many of those seats are more than two units from an aisle.

Sure, I guess they can put ceiling evac into it; but what happens if it ends up upside-down on its back?

The widest there is 5 seats, which is common to DC10, MD11, some 777. The limit is no more than two seats between you and the aisle, so that middle seat of 5 (though awful to be stuck in) is legal. That's the issue facing the 11-abreast A380 proposal: it would have to be configured 3-5-3, as 4 seats on the window wouldn't pass.

Wasn't this the windowless conceptual design that can allow for a true aerodynamic design??

Where will be located the first class? Towards the center maybe?

By creating a hole in the center of the body, this design addresses somehow the lack of natural light reaching the areas distant from the leading edge. Emirates could turn the center into a nice patio or an oasis  .

I guess that's what i get for looking at it on a phone... that whole top circle seemed like 11, 9, and 7 seats in a row, but now I can see that that's just an axis line drawn through them.

Well I had to look again to be sure I saw spacing indicating an aisle, versus just the axis line. But it does appear to be 5-5.

Firstly, can I just say I'm not too sure about the ladies medication angle here, they're more of a Shorts SkyVan over here (rectangular box).
But I wouldn't get too hung up on the seating arrangements - they're not really relevant to the patent.

I think the real patent is taken up with how to embed a pressure vessel within a BWB. A disc is the most obvious answer, but as it gets bigger the loads in the vertical axis become a constraint - hence the doughnut. Three things that struck me:
1. the proposed exit arrangement (see p7 fig10)
2. The use of the, er, "Ringpiece" for storing baggage (say fig16 p9)
3. How oval (and other) configurations might fit (p7-8)
Haven't read all the blurb in it yet - will when sober - but it suggests a continued attempt to evaluate "exotic" configurations in the future (NB replacement?)
Down with that sort of thing!

LOL, that's awesome.     

Particularly seeing as how informative your post is!

It's interesting, but it suffers from some major limitations. The biggest is the lack of expandability. With a linear fuselage, you can just stretch the fuselage. Hence, A318-A321. With this, any expansion of the fuselage requires expansion of the entire airframe. Even if the eliptical configuration is used, it still requires major structural modifications. Also, the depicted methods of embarcartion/debarcation would require major changes to existing airport infrastructure. A much larger airframe with more under-body clearance might be more suited to this. A boarding elevator could also be built in, but that would add weight and mechanical complexity.

It's still a very interesting idea, though.

So, I can't determine from the patent language, or was it established elsewhere beyond this patent, does the "donut hole" assist the aerodynamics of the flying body?

Tangential, I think the patent verbiage could have been much simpler if they simply used the term "torus" for the donut-cylinder, "a-space-defined-outside-the-cabin-and-inside-the-aircraft".
